Hi all, Willie here. This time we’re going to step away from the keyboard and get architectural. But no ivory towers here. In my next two blog posts, I’m going to give you something that will get you out of lots of pointless meetings.
Got your attention yet? Good!
If you’re in devops, one of the things that you have to figure out is how to collect up all the information that will allow you to manage your configuration and also keep your apps up and running. This isn’t too hard when you have two apps sitting on a single server. It’s much harder when you have 400 apps deployed to thousands of servers across multiple environments and data centers.
So how do you do that? Let’s start off by looking at some things that just don’t work. In my next post I’ll share with you an approach that does work.
Some quick background
Probably owing to some psychological glitch, I’ve always been an information curator. Especially when I was in management, it was always important to me to understand exactly where my apps were deployed, which servers they were on, which services and databases they depended on, which servers those services and databases lived on, who are the SMEs for a given app, and so on.
If you work in a small environment, you’re probably thinking, “what’s the big deal?”
Well, I don’t work in a small environment, but the first time I undertook this task, I probably would have said something like, “no sweat.” (That’s the developer in me.) Anyway, for whatever reason, I decided that it was high time that somebody around the department could answer seemingly basic questions about our systems.
Attempt #1: Wiki Wheeler
The first time I made the attempt (several years ago), I was a director over a dozen or so app teams. So I created a wiki template with all the information that I wanted, and I chased after my teams to fill it out. My zeal was such that, unbeknownst to me, I acquired the nickname “Wiki Wheeler”. (One of my managers shared this heartwarming bit of information with me a couple years later.) I guess other managers liked the approach, though, because they chased after their teams too.
This approach started out decently well, since the teams involved could manage their own information, and since I was, well, Wiki Wheeler. But it didn’t last. Through different system redesigns and department reorgs, wiki spaces came and went, some spaces atrophied from neglect, and there was redundant but contradictory information everywhere. The QA team had its own list, the release guys had their list, the app teams had their list. The UX guys might have even gotten in on the act. Anyway, after a year or so it was a big mess and to this day our wiki remains a big mess.
Attempt #2: My huge Visio
The second time, my approach was to collect the information from all the app development teams. We had hundreds of developers, so to make things efficient, I sent out a department-wide e-mail telling everybody that I was putting together a huge Visio document with all of our systems, and I’d appreciate it if they could reply back with the requested information. And while I had to send out more nag e-mails than I would have liked, the end result was in fact a huge Visio diagram that had hundreds of boxes and lines going everywhere. I was very proud of this thing, and I printed out five or six copies on the department plotter and hung them on the walls.
How long do you think it was before it was out of date?
I have no idea. I seriously doubt that it was ever correct in the first place. Nobody (myself included) ever used the diagram to do actual work, and its chief utility was in making our workplace look somewhat more hardcore since there were huge color engineering plots on the walls.
There was one additional effect of this diagram, though I hesitate to call it utility. I acquired the wholly undeserved reputation for knowing what all these apps were and how they related to one another. This went on for years through no fault of my own. I mention it because it’s relevant for the next attempt.
Attempt #3: Disaster recovery
This one wasn’t my attempt, but it’s still worth describing since I have to imagine that we aren’t the only ones who ever tried it.
As a rapidly growing company, disaster recovery became an increasingly big deal for us several years back, and there was a mandate from up high to put a plan in place. This involved collecting up all the information that would allow us to keep the business running if our primary data center ever got cratered. The person in charge of the effort spent about two years meeting with app teams or else “experts” (me, along with others who, like me, had only the highest-level understanding of how things were connected up) and documenting it on a Sharepoint site where nobody could see it.
This didn’t work at all. Most people were too busy to meet with her, so the quality of the information was poor. Apps were misnamed, app suites were mistaken for apps, and to make a long story short, the result was not correct or maintainable.
Attempt #4: Our external consultants’ even bigger Visio
Following a major reorg, we brought in some external consultants and they came up with their own Visio. By this time I had already figured out that interviewing teams and putting together huge Visios is a losing approach, so I was surprised that a bunch of highly-paid consultants would use it. Well, they did, and their diagram was, well, “impressive”. It was also (to put it gently) neither as helpful nor as maintainable as we would have liked.
Attempt #5: HP uCMDB autodiscovery
We have the HP uCMDB tool, and so our IT Services group ran some automated discovery agents to populate it with data. It loaded the uCMDB up with tons of fine-grained detail that nobody cared about, and we couldn’t see the stuff that we actually did care about (like apps, web services, databases, etc.).
Attempt #6: Service catalog
Our IT Services group was pretty big on ITIL, so they went about putting together a service catalog. The person doing it collected service and app information into an Excel spreadsheet and posted it to a Sharepoint site. But this didn’t really get into the details of configuration management. It was mostly around figuring out which business services we offered and which systems support which services.
They ended up printing out a glossy, full-color service catalog for the business, but nobody was really asking for it, so it was more of a curiosity than anything else.
There were other attempts too (Paul led a couple that I haven’t even mentioned), but by now you get the picture.
So why did these attempts fail?
To understand why these attempts failed, it helps to look at what they had in common:
- First, they generally involved trying to collect up information from SMEs and then putting it in some kind of document. This could be wiki pages, Visio diagrams, Word docs on Sharepoint or an Excel spreadsheet.
- Once the information went there, nobody used it. So the information, if it was ever correct and/or complete in the first place, was before long outdated, and there wasn’t any mechanism in place to bring it up to date.
In general, people saw the problem as a data collection problem rather than a data management problem. There needs to be a systematic, ongoing mechanism to discover and fix errors. None of the approaches took the management problem seriously at all—they all simply assumed that the organization would care about the data enough to keep it up to date.
In the next installment, I’ll tell you about the approach we eventually figured out. And as promised, that’s also where I’ll explain how to get rid of some of your meetings.
Interested in configuration management? I’m working on an open source CMDB called Zkybase.

19 June 2000
Disease Outbreak Reported
An outbreak of acute haemorrhagic fever syndrome has been reported from an isolated village in Gulran district, Afghanistan. Disease symptoms are compatible with Crimean-Congo haemorrhagic fever (CCHF). An international team, coordinated by WHO, arrived in the affected area on 16 June to control and investigate this outbreak. The team comprises experts from the WHO Collaborating Centre at the National Institute of Virology (NIV-South Africa), Epicentre (France) and WHO.
Preliminary findings indicate that cases began at the beginning of May and are continuing to occur. Twenty-five suspect cases including 15 deaths were identified by the team. Samples were collected and transported to NIV where diagnostic laboratory tests will be performed to establish the aetiology of the outbreak.
The team has provided basic protective materials (gloves, masks), disinfectants (chlorine bleach) and instructions for their use in caring for patients with bleeding symptoms. An isolation area has been identified in the hospital in Herat to deal with haemorrhagic patients and will be equipped by WHO. Training in barrier nursing will be provided to medical and nursing staff.

Django ORM if you already know SQL
If you are migrating to Django from another MVC framework, chances are you already know SQL.
In this post, I will be illustrating how to use Django ORM by drawing analogies to equivalent SQL statements. Connecting a new topic to your existing knowledge will help you learn to use the ORM faster.
Let us consider a simple base model for a person with attributes name, age, and gender.
To implement the above entity, we would model it as a table in SQL.
CREATE TABLE Person (
id int,
name varchar(50),
age int NOT NULL,
gender varchar(10),
);
The same table is modeled in Django as a class which inherits from the base Model class. The ORM creates the equivalent table under the hood.
class Person(models.Model):
name = models.CharField(max_length=50, blank=True)
age = models.IntegerField()
gender = models.CharField(max_length=10, blank=True)
The most used data types are:
| SQL | Django |
|---|---|
INT |
IntegerField() |
VARCHAR(n) |
CharField(max_length=n) |
TEXT |
TextField() |
FLOAT(n) |
FloatField() |
DATE |
DateField() |
TIME |
TimeField() |
DATETIME |
DateTimeField() |
The various queries we can use are:
SELECT Statement
Fetch all rows
SQL:
SELECT *
FROM Person;
Django:
persons = Person.objects.all()
for person in persons:
print(person.name)
print(person.gender)
print(person.age)
Fetch specific columns
SQL:
SELECT name, age
FROM Person;
Django:
Person.objects.only('name', 'age')
Fetch distinct rows
SQL:
SELECT DISTINCT name, age
FROM Person;
Django:
Person.objects.values('name', 'age').distinct()
Fetch specific number of rows
SQL:
SELECT *
FROM Person
LIMIT 10;
Django:
Person.objects.all()[:10]
LIMIT AND OFFSET keywords
SQL:
SELECT *
FROM Person
OFFSET 5
LIMIT 5;
Django:
Person.objects.all()[5:10]
WHERE Clause
Filter by single column
SQL:
SELECT *
FROM Person
WHERE id = 1;
Django:
Person.objects.filter(id=1)
Filter by comparison operators
SQL:
WHERE age > 18;
WHERE age >= 18;
WHERE age < 18;
WHERE age <= 18;
WHERE age != 18;
Django:
Person.objects.filter(age__gt=18)
Person.objects.filter(age__gte=18)
Person.objects.filter(age__lt=18)
Person.objects.filter(age__lte=18)
Person.objects.exclude(age=18)
BETWEEN Clause
SQL:
SELECT *
FROM Person
WHERE age BETWEEN 10 AND 20;
Django:
Person.objects.filter(age__range=(10, 20))
LIKE operator
SQL:
WHERE name like '%A%';
WHERE name like binary '%A%';
WHERE name like 'A%';
WHERE name like binary 'A%';
WHERE name like '%A';
WHERE name like binary '%A';
Django:
Person.objects.filter(name__icontains='A')
Person.objects.filter(name__contains='A')
Person.objects.filter(name__istartswith='A')
Person.objects.filter(name__startswith='A')
Person.objects.filter(name__iendswith='A')
Person.objects.filter(name__endswith='A')
IN operator
SQL:
WHERE id in (1, 2);
Django:
Person.objects.filter(id__in=[1, 2])
AND, OR and NOT Operators
SQL:
WHERE gender='male' AND age > 25;
Django:
Person.objects.filter(gender='male', age__gt=25)
SQL:
WHERE gender='male' OR age > 25;
Django:
from django.db.models import Q
Person.objects.filter(Q(gender='male') | Q(age__gt=25))
SQL:
WHERE NOT gender='male';
Django:
Person.objects.exclude(gender='male')
NULL Values
SQL:
WHERE age is NULL;
WHERE age is NOT NULL;
Django:
Person.objects.filter(age__isnull=True)
Person.objects.filter(age__isnull=False)
# Alternate approach
Person.objects.filter(age=None)
Person.objects.exclude(age=None)
ORDER BY Keyword
Ascending Order
SQL:
SELECT *
FROM Person
order by age;
Django:
Person.objects.order_by('age')
Descending Order
SQL:
SELECT *

ORDER BY age DESC;
Django:
Person.objects.order_by('-age')
INSERT INTO Statement
SQL:
INSERT INTO Person
VALUES ('Jack', '23', 'male');
Django:

SET age = 20
WHERE id = 1;
Django:
person = Person.objects.get(id=1)
person.age = 20

Rather than building & maintaining our own td-charts D3 component, we've opted instead to partner with an external open-source library. Charts components are a massive undertaking and would have detracted from the features & support of Covalent.
The NGX-Charts team took the exact approach we would have and did a fantastic job building a framework that can be extended. We therefor are an official partner and will be contributing massive additions.
These are the key decision points in selecting NGX-Charts:
Since our apps largely span from Orange / Blue / Grey families, here's some recommended palettes:

This table gives you a detail and accurate view of expeditions. Expedition scorer also uses the configuration you set in this tab to figure out some best set of expeditions to be run parallelly for you.
If this is the first time you run into this page:
Reset
.otherwise, have fun messing around with these views and sorting methods xD
Expedition configuration represents how you normally run expedtions: for a single expedition, this includes whether you want to guarantee great success, how many Daihatsu your fleet usually carry and what fleet composition you use for running the expedition.
Each expedition is associated with its own configuration.
For each expedition, a configuration consists of 2 parts:
Income Modifier
is a number applied directly to the basic resource income. For example, great success grants you 50% extra resource income, which is equivalent to an income modifier of 1.5
(i.e. 150%). Having 4 daihatsu in your fleet will further boost the income modifier to 1.8
(= 1.5 x (1 + 0.05x4) = 1.5 x 1.2
).
There are two methods of configuring income modifier:
Normal
method allows you to specify whether great success is intended and how many Daihatsu you want to carry, and works out the income modifier for you.
Custom
method is for advanced users. You can fill in an income modifier directly in case you have Toku Daihatsu or improved Daihatsu and want more accurate results. For example, if you want 4 fully improved Daihatsu (122%) together with guaranteed great success (150%), Your income modifier will be 1.83
(=1.22 x 1.5
).
Resupply Cost
is the fuel and ammo cost per run.
There are two ways of configuring resupply cost:
Normal
method estimates the fuel and ammo cost for you, all you need to do is to set Number of Ships
and wildcard
. Take expedition 5 as an example, for a successful run you would just need 4 ships including one light cruiser (1CL
) and two destroyers (2DD
). For an almost guaranteed great success rate (about 95%), however, you would need 5 sparkled ships in total. and the actual fleet composition would be 1CL4DD
. Here the Number of Ships
is 5
in total, and in addition to the require 1CL2DD
, you have two DD
as wildcard
ships.
In case you are interested about how the resupply cost is estimated, see Cost Model
section.
Custom
method lets you accurately specify the cost: say if you have a fleet of 6 Mutsuki-class destroyers for expedition 38 (so it's 80% fuel and 80% ammo consumption), you would set both Fuel
and Ammo
to 72
. Because one Mutsuki-class destroyer will cost 12 fuel and 12 ammo per run. and you have 6 of them in fleet summing up to 72
(=12x6
) fuel and 72
ammo cost per run.
If you are entering this tab for the first time, you need to reset your configuration, please find Reset Configuration
section below and pick one resetting method you like.
All these functions are disabled when you are editing expeditions.
General Config
button do?Normally expedition table tries to represent your configuration instead of some general numbers. A General Config
view forces every expedition configuration to show its actual bonus and resupply cost.
Reseting allows you to initialize your expedition configuration.
There are two resetting methods:
Normal
method sets default configuration to all expeditions. A default configuration considers basic income as your final income - not aim for great success and no Daihatsu is carried.
Recommended
method tries to aim for great success if one expedition has decent income per run. For an expedition to be considered decent, its fuel + ammo + steel + bauxite x 3
value must be no less than 500
.
Optionally you can let KC3 guess some configuration from your recent expedition history.
Gross Income
, Net Income
and Basic Income
?Basic Inome
is the amount of resource you get when you have a normally successful expedition.Gross Income
considers everything: great success, Daihatsu, except resupply cost.Net Income
is Gross Income
but with resupply cost in mind.That would mean even more complicated user interface and algorithm to support it. If you do want to try things like having different amount of Daihatsu for different expeditions, you can have both this tab and Expedition Scorer
opened, change configs in this tab and whenever you click Calculate
button on Expedition Scorer
, it always uses your latest configs.
Clicking on an already-active sorting method reverses the whole list.
Because switching view methods, especially between Total
view and Hourly
view makes the current list no longer sorted. On the other hand, if current list is sorted by expedition id or time, it will be kept.
Cost Model
?A cost model is a function that estimates resupply cost given a fleet composition. You can work out the resupply cost manually by adding up corresponding table cells in Cost Model
section.
For example, given fleet composition 1CL5DD
, with 80% fuel and ammo cost:
CL - 1 Ship
cell, which indicates the cost is 20 fuel and 20 ammo.DD - 5 Ships
cell, which indicates the cost is 60 fuel and 60 ammo.Therefore 1CL5DD
sums up to a total cost of 80 fuel and 80 ammo.
| Ship Type | 1 Ship | 2 Ships | 3 Ships | 4 Ships | 5 Ships | 6 Ships |
|---|

Steem Developer Portal
JS: Vote On Content
Create a weighted up or down vote on a comment/post.
Full, runnable src of Vote On Content can be downloaded as part of the JS tutorials repository.
This tutorial will take you through the process of preparing and submitting a vote
using the broadcast
operation.
Because this tutorial essentially produces spam, it will be pointed at a Steem testnet. The testnet is an open resource,
so the default account and posting key in this tutorial may have been changed by another developer learning the ropes.
If that happens, you’ll want to create a new account on the testnet and use that account’s credentials instead.
To learn more about the testnet, including an easy way to create a play account, visit https://testnet.steem.vc/
Intro
We are using the broadcast.vote
function provided by the dsteem
library to send the transaction through to the
network. On the Steem platform, posts and comments are all internally stored as a comment
object, differentiated by
whether or not a parent_author
exists. When there is no parent_author
, then it’s a post, when there is, it’s a
comment. Voting is done on either of the two based on the author and permlink of the comment. There are 5 parameters
required for the voting operation:
- Username - The username of the account making the vote (the voter)
- Privatekey - This is the private posting key of the voter
- Author - The author of the comment/post that the voter is voting on
- Permlink - The unique identifier of the comment/post of the author
- Weight - This is the weight that the vote will carry. The value ranges from -10000 (100% flag) to 10000 (100% upvote)
Due to the low amount of posts on the testnet we added an additional step to create a post before we vote on it. The values are auto loaded in the respective input boxes. A full tutorial on how to create a new post can be found on the Steem Devportal
Steps
- Configure connection Configuration of
dsteem
to communicate with a Steem blockchain - Create new post Creating a new post on the testnet
- Input variables Collecting the required inputs via an HTML UI
- Broadcast Creating an object and broadcasting the vote to the blockchain
1. Configure connection
As usual, we have a public/app.js
file which holds the Javascript segment of the tutorial. In the first few lines we define the configured library and packages:
import { Client, PrivateKey } from 'dsteem';
import { Testnet as NetConfig } from '../../configuration'; //A Steem Testnet. Replace 'Testnet' with 'Mainnet' to connect to the main Steem blockchain.
let opts = { ...NetConfig.net };
//connect to a steem node, testnet in this case
const client = new Client(NetConfig.url, opts);
Above, we have dsteem
pointing to the test network with the proper chainId, addressPrefix, and endpoint by importing from the configuration.js
file. Because this tutorial is interactive, we will not publish test content to the main network. Instead, we’re using the testnet and a predefined account which is imported once the application loads, to demonstrate voting on content.
window.onload = () => {
const account = NetConfig.accounts[0];
document.getElementById('username').value = account.address;
document.getElementById('postingKey').value = account.privPosting;
};
2. Create new post
A new blog post is created on the testnet with the necessary variables for the vote function being allocated as well. If a post is successfully created it will display a block number and a value will be assigned to the permlink
variable.
//refer to "10_submit_post" in the tutorials folder for creating a post on steemit
//create post function
window.createPost = async () => {
//get private key
const privateKey = createPrivateKey();
//get account name
const account = document.getElementById('username').value;
//for content
const time = new Date().getTime();
//get title
const title = `developers.steem.io - JS-T:17 ${time}`;
//get body
const body = `Go to [developers.steem.io](https://developers.steem.io) for the latest in Steem tutorials! This post was created by someone using the active version of those tutorials at [https://github.com/steemit/devportal-tutorials-js](https://github.com/steemit/devportal-tutorials-js)
${time}`;
//get tags and convert to array list
const tags = 'blog';
const taglist = tags.split(' ');
//make simple json metadata including only tags
const json_metadata = JSON.stringify({ tags: taglist });
//generate random permanent link for post
const permlink = Math.random()
.toString(36)
.substring(2);
client.broadcast
.comment(
{
author: account,
body: body,
json_metadata: json_metadata,
parent_author: '',
parent_permlink: tags,
permlink: permlink,
title: title,
},
privateKey
)
.then(
function(result) {
document.getElementById('permlink').innerHTML = permlink;
document.getElementById(
'postLink'
).innerHTML = `Included in block: ${
result.block_num
}`;
document.getElementById('postResult').style.display = 'flex';
document.getElementById('permlink').value = permlink;
},
function(error) {
console.error(error);
}
);
};
You may have noted the mystery function createPrivateKey()
. It’s a convenience function that allows us to give the
user some meaningful UI feedback if they put in a bad posting key. The important part of it is
return dsteem.PrivateKey.fromString(<somestring>)
but its full glory can be seen in the snippet below
const createPrivateKey = function() {
try {
return dsteem.PrivateKey.fromString(
document.getElementById('postingKey').value
);
} catch (e) {
const resultEl = document.getElementById('result');
resultEl.className = 'form-control-plaintext alert alert-danger';
resultEl.innerHTML = e.message + ' - See console for full error.';
throw e;
}
};
3. Input variables
The required parameters for the vote operation is recorded via an HTML UI that can be found in the public/index.html
file. The values are pre-populated in this case with a testnet demo
account. The vote weight is input via a slider as this value can range between -10000 and 10000 denoting either a 100% flag or 100% upvote.
The parameter values are allocated as seen below, once the user clicks on the “Submit” button.
window.submitVote = async () => {
//we'll make use of resultEl in multiple child scopes. This is generally good practice.
const resultEl = document.getElementById('result');
resultEl.innerHTML = 'pending...';
//get all values from the UI//
//get account name of voter
const voter = document.getElementById('username').value;
//get private posting key
const privateKey = createPrivateKey();
//get author of post/comment to vote
const author = document.getElementById('author').value;
//get post permalink to vote
const permlink = document.getElementById('permlink').value;
//get weight of vote
const weight = parseInt(
document.getElementById('currentWeight').innerHTML,
10
);
....
The weight
parameter is required to be an interger for the vote operation so we parse it from the UI text field. The permlink
value is retrieved from the create post
function.
4. Broadcast
We create a vote object
with the input variables before we can broadcast to the blockchain.
const vote = {
voter,
author,
permlink,
weight, //needs to be an integer for the vote function
};
After which we can complete the broadcast.vote
operation with the created object and private posting key received from the input UI. The result of the vote is displayed on the UI to confirm whether it was a success
or failed
with details of that process being displayed on the console.
client.broadcast.vote(vote, privateKey).then(
function(result) {
console.log('success:', result);
resultEl.className = 'form-control-plaintext alert alert-success';
resultEl.innerHTML = 'Success! See console for full response.';
},
function(error) {
console.log('error:', error);
resultEl.className = 'form-control-plaintext alert alert-danger';
resultEl.innerHTML =
error.jse_shortmsg + ' - See console for full response.';
}
);
window.onload = () => {
var voteWeightSlider = document.getElementById('voteWeight');
var currentWeightDiv = document.getElementById('currentWeight');
currentWeightDiv.innerHTML = voteWeightSlider.value;
voteWeightSlider.oninput = function() {
currentWeightDiv.innerHTML = this.value;
};
More information on how to use the broadcast
operation and options surrounding the operation can be found on the Steem Devportal

The Arrow Highway Multimodal Regional Corridor Plan builds on previous and ongoing planning efforts, ties together extensive collaboration involving multiple agencies, cities, and their residents, and sets a clear path forward to improve active transportation and transit access in the San Gabriel Valley. The final plan can be viewed
here.
As a civic data analyst and planner, I developed a highly detailed cross-sectional dataset of roadway characteristics for the study corridors. This data was used to identify safety, comfort, and access issues along the corridors, and to guide the development of plan recommendations.
I used the Python programming language to create automated, well-documented, and easily adjustable scripts to model the impacts of recommended projects, and to score and prioritize recommended projects based on a framework developed in collaboration with the public and planning agencies across all of the corridor cities.
I created dozens of graphics and maps used in the
final plan (including the two maps presented on this page), and collaborated with our team's engineers to develop cost estimates for each of the plan's recommended projects.


Waldorf Blofeld
Multi Patch Editor
This editor will work with the Waldorf Blofeld, the Waldorf Blofeld with SL Option, and the Waldorf Blofeld Keyboard (which automatically comes with the SL option).
Communicating with Edisyn
Set your Blofeld to send Sysex only, not Ctl nor Ctl+Sysex. Also make sure that Ctrl Receive is on.
Set Edisyn's send and receive channels to the Blofeld's MIDI Channel, and set th
e Synth ID to the Blofeld's Device ID.
The Play Button
Each Part has a button called Play. This sets the status to "play" (versus "mute").
The Show Button
Each Part has a button called Show. This shows the given sound (bank and number) as a separate Blofeld Single editor panel.
Gotchas
Multimode on the Blofeld is a mess.
-
The Blofeld's Multimode sysex is entirely undocumented, and this patch editor is the result of reverse engineering. There may be errors: please report them.
- Edisyn cannot tell the Blofeld to switch to Multimode or to Single-Mode. If you press the "Show" button for a part, Edisyn will load the patch but cannot switch to it on the Blofeld. To switch, you must first put the Blofeld in Single mode, then press Edisyn's "Show" button.
- The Blofeld doesn't send or receive sysex for updating individual Multimode parameters, so you won't see changes on the Blofeld (or Edisyn) when tweaking a parameter on the other.
-
If you save a multimode patch on the Blofeld, it corrupts the first letter of the name of every patch! This is not permanent (just reboot your Blofeld), but it's reported to Edisyn when Edisyn tries to load the patch from temporary memory again, so you'll see a corrupted patch name on receiving a patch.
- (On purpose) you can't mutate or merge the Play, Local, MIDI, or USB options as they turn on or off the ability to test playing a note at all.
- Effects work strangely in Multimode. Part 1's Effect 2 settings are applied to all parts regardless of their own settings. Also, Parts 1 through 4 can have their own independent settings for Effect 1, but Parts 5 through 16 do not have Effect 1 at all (it's just turned off). In either case, you set the mix level of the Effect in question for each Part in its own program patch, not in the multimode patch.
Librarian Support
Edisyn can request all the patches from the Blofeld at the same time via the menu Request All Patches from Synth. It's a lot faster than the standard download methods.
Thanks
Thanks to Gareth Whittock<EMAIL_ADDRESS>for bug reports and clueing me in on an undocumented method for changing patches in multimode.

It was midnight and I hadn't started work on my answer to the question for tomorrow's test on public policy. I hadn't slept for a couple of days and I was feeling slightly panicked as I rifled through books looking for some quotes I could use. It was then that I decided to go to my test tripping. What did I have to lose? And besides, it would be interesting.
I had used morning glories several times before. I've never vomited with them, or had anything worse than a slight stomach ache. I was pretty certain that I could keep it together on them. So, after a few hours hours working on the question, I ground up 200 morning glory seeds and, at five AM, I ate them. The worst thing about morning glories is eating them. The texture lodges in your throat and makes you gag. However, I've discovered a good way to get them down. I put the seeds in a shallow bowl, which I filled with orange juice. Take a gulp of the seeds and juice, then add more juice. Keep doing this until the seeds are gone.
The timing of consumption was intentional. For me, morning glories take around five hours to peak. My test was an hour long and started at 10am. I intended to reach the peak of the trip during the test. The morning glories came on slowly as expected. I left my halls to go to the test a little early - I wanted to buy some cigarettes and perhaps have some breakfast. By now, I was having closed-eye visuals and the world looked subtly different. The walk between the halls and the class is about ten minutes. As I walked, my thoughts raced. I had trouble preventing myself from grinning madly at people. I thought about how I could be paranoid and suddenly, I was convinced that I was convinced that people knew that I was tripping. This made me grin even more. It was as if there was a huge joke and I was the only one who knew the punchline.
I reached the shop and bought my cigarettes. This was the first interaction I'd had with anyone. I believe that I handled myself well and quite normally, although I'm not sure how big my pupils were.  I continued to the canteen where I decided that I couldn't stomach any breakfast, but got myself a coffee instead. I sat outside, looking at the static in the sky when Kali, a girl in my class came up to my table. I chatted to her much more ably than usual - normally I'm somewhat asocial and have difficulty conversing with people I don't like. However, today I talked easily. I almost wanted to tell her that I was tripping, but I managed to restrain myself.
The test itself was fine. Before, I had been concerned about whether I'd actually be able to write, but from the time the test began, to the time it ended I was one conduit of knowledge on the subject. I didn't even need to use the cheat-notes that I'd written on my wrist. The trip peaked, as expected, around half-way through. It was very intense - suddenly, colors flowed over everything, flickering and strobing. I sat back and enjoyed it for a minute or so, and then continued to write.
I believe that I did very well on the test, although I haven't got my result yet.
Afterwards, I met up with my friend Jon and went shopping for Christmas gifts. The shopping center was a very stimulating environment - almost overwhelming. As I came down, things began to make more sense. I was left feeling happy and energised, and not in the least bit tired - almost as if the morning glories had paid back the sleep debt of the last couple of days.
It might be the case that the morning glories actually enhanced my ability to think whilst taking the test - I certainly couldn't have remembered the dates and names that I did. All in all, another positive MG experience for me.

4. The Algorithm¶
This section describes the algorithm.
A curly bracket can be divided into 6 parts: 4 arcs and 2 straight lines.
For easy reference, name the 4 arcs from left to right (assuming the bracket is pointing up) as: arc1, arc2, arc3 and arc4. Also, name the two lines as line1 and line2. If all the points of all the arcs are known, then, by connecting the last point of arc1 and the first point of arc2, line1 can be formed. Similarly, line2 can also be formed once all the points of arc3 and arc4 are known. Therefore, the crucial thing here is to get all the points of all the arcs.
The angle of the straight line formed by the starting point and the end point can be calculated by an atan method that considers quadrants. The radius of the arcs, assuming they are quater circles, can be set as proportional to the lenght of the aforementioned straight line. Let the user decide the proportion.
The centre of arc1 is on the aforementioned straight line and distances from the starting point by the length of the radius. All the points of arc1 can then calculated. The detailed method is in the source code. Similarly, all the points of arc4 can be calculated.
The centre of arc2 has a perpendicular ditance to the aforementioned straight line of twice the radius. It also distances from the midpoint of the straight line of one radius (along the direction of the straight line). By accounting the angle rotation of the arc, all the points of arc2 can be calculated (see source code for details). Similarly, all the points of arc3 can be calculated.
This algorithm has a lot to do with playing with geometry. You can also play with Sigmoid function to make curly brackets (but I like this one here).
For the text annotation, it is actually quite simple. Just use standard matplotlib text should be suffice. The only thing need to take into account is how far the text should be from the summit of bracket. This can be achieved by allow line breaks to be pad to the text. But whether to pad the lines before or after the text depends on where the bracket is, since the summit can be pointing up or down depending on the quadrants.
The catch is that the axes coordinates need to transformed into screen coordinates to calculate the pixels and the transform back. Otherwise the bracket may appear as just a straight line.
Log scale can be dealt with just by logging the axis/axes limits and then expoential the arcs’ points back.
The real difficult thing is the symlog scale since it is part log, part linear and this breaks the transformation and makes the bracket looks funny.

Electricity vandals throw nine Anambra communities into darkness
by NANThe Enugu Electricity Distribution (EEDC) on Monday said that about nine communities were affected by the power outage resulting from the vandalism of the Enugwu-Ukwu 33KV line.
Mr Emeka Ezeh, Head of EEDC Communications Department, made this known in a statement made available to newsmen in Awka.
Ezeh said the vandalism on its installation was carried out early Sunday.
He said that valuable equipment was carted away from the line which transmits to Enugwu-Ukwu, Abagana, Ukpo and Nimo 11KV feeders.
He said the communities affected were, Enugwu-Ukwu, Abagana, Ukpo, Nimo, Nawfia, Umuokpu, Abba, Ifitedunu, and parts of Amawbia, left without electricity supply.
According to him, EEDC regrets to inform her esteemed customers under Enugwu-Ukwu 33KV line that the current loss of supply being experienced is as a result of the vandalism of the 33KV network feeding them.
“This network radiates from Agu Awka Transmission Substation, Awka, Anambra.
“Materials carted away include five spans of aluminum conductors, all-fiber cross-arms and 33KV pot insulators and also a broken high tension pole.
“Consequently, our customers in the entire Enugwu-Ukwu, Abagana, Ukpo, Nimo, Nawfia, Umuokpu, Abba, Ifitedunu and parts of Amawbia are without electricity supply,” he said.
Ezeh said that efforts were on to fix the problem and restore power supply.
He urged customers of EEDC to see the protection of its installations as a shared responsibility.
“Plans are on to address this challenge and we assure our customers that supply will be restored as soon as repairs and replacement are completed.
“EEDC remains committed to providing her esteemed customers with improved service delivery while soliciting for their continued support in ensuring that such an incident does not occur in the network,” he said.

2 patients diagnosed in China with pneumonic plague
by Brie StimsonTwo people were reportedly diagnosed with the highly infectious, potentially fatal pneumonic plague in a hospital in Beijing, Chinese authorities revealed Tuesday.
The announcement comes as the government faces criticism for not being transparent in disclosing cases, The New York Times reported.
Officials said the patients came from a remote part of Inner Mongolia in Northern China. The Chinese Center for Disease Control and Prevention advised Beijing residents that the risk of contracting that disease is “extremely low,” according to The Times.
The patients were isolated and the places they came into contact with were disinfected.
The pneumonic plague is one of three strains, including the septicemic and the bubonic plague, infamous for killing tens of millions of Europeans in the Middle Ages.

The plague is usually contracted after being bitten by a rodent flea carrying the Yersinia pestis bacterium or by handling an infected animal, according to the CDC.
The CDC says with prompt care the disease can be effectively treated. Otherwise, it can be fatal.
Between 2010 and 2015, 3,248 cases were reported globally and 584 patients died from the disease, according to the World Health Organization.
Last May, a couple in Mongolia died of bubonic plague after eating the raw kidney of a marmot.
Dr. Li Jifeng at Beijing Chaoyang Hospital, in the district where the patients sought treatment, said they came to the hospital on Nov. 3 but officials have not confirmed the claim, The Times reported.
Dr. Li wrote on WeChat that she treated a middle-aged man who had a persistent fever and cough, which his wife had also contracted.
“I couldn’t guess what pathogen caused this pneumonia. I only knew it was rare,” she wrote.

Command-Line Tutorial ∞
There are 2 ways to use panstamps, either via the command-line or import it into your own python code and use it from there.
Command-Line ∞
Full usage options can be found by typing:
panstamps -h
Here I’ll run through the basics. By default the command will only download the fits files for the location given. To download the stack fits cutouts for M82 run the command:
panstamps stack 09:55:52.2 +69:40:47
By default the gri filter, 1 arcmin fits cutouts are downloaded:
To increase the image width and download all filters, run the command:
panstamps --width=4 --filters=griyz stack 09:55:52.2 +69:40:47
As you can see we now have a larger cutout:
JPEGS ∞
To download the jpegs, and not the fits files rerun the command with the correct flags set. We’ll also use the --downloadFolder
option to assign the download directory.
panstamps -Fj --width=4 --filters=gri --downloadFolder=/Users/Dave/Desktop/m81 stack 09:55:52.2 +69:40:47
This downloads the jpegs and adds some useful annotation, which can be switched off if required.
Sometimes it maybe useful to add a transient marker at the centre of the image:
panstamps -FjAt --width=4 --filters=gri --downloadFolder=/Users/Dave/Desktop/m81 stack 09:55:52.2 +69:40:47
Or grab the color image as well as/instead of the single filter images:
panstamps -FJc --width=4 --filters=gri --downloadFolder=/Users/Dave/Desktop/m81 stack 09:55:52.2 +69:40:47
Note the code will try its best to choose a colour for the annotation lines and text to make them contrast well against the background image.
Finally you can invert the image colors or convert the image to greyscale:
panstamps -FJci --width=4 --filters=gri --downloadFolder=/Users/Dave/Desktop/m81 stack 09:55:52.2 +69:40:47
panstamps -FJcig --width=4 --filters=gri --downloadFolder=/Users/Dave/Desktop/m81 stack 09:55:52.2 +69:40:47
Temporal Constraints (Useful for Moving Objects) ∞
For moving objects, alongside spatially filtering the panstarrs images, we also require a temporal filter. We need to be able to request images at a sky-position that were taken within a given time range. With panstamps we have the option of passing a time-window to filter the images by via the mjdStart
and mjdEnd
variables:
For example I can run:
panstamps -Fj --width=4 --filters=gri --downloadFolder=~/Desktop/movers warp<PHONE_NUMBER> 28.2374845 55246.63 55246.64
to only return the 2 images I want within the temporal window at the location in the sky.
It’s also possible to request the closest warp image taken before or after a requested MJD by using the closest
flag. For example, to request the closest r-band warp taken before MJD=`55246.64` for the location above, run the command:
panstamps -Fj --closest=before --width=4 --filters=gri --downloadFolder=~/Desktop/movers<PHONE_NUMBER> 28.2374845 55246.64
To request the closest warp taken after the given MJD then use --closest=after
.
Oftentimes it’s useful to download the closest warp within a given time-window, e.g. closest warp in time of the requested MJD taken up to 3 mins before. To do so pass in a postive or negative integer to represent the time-window in seconds, like so:
panstamps -Fj --closest=-120 --width=4 --filters=gri --downloadFolder=~/Desktop/movers<PHONE_NUMBER> 28.2374845 55246.64
Importing to Your Own Python Script ∞
To use panstamps within your own scripts please read the full documentation. But for those of you that can’t wait, this snippet should give you the basics:
from panstamps.downloader import downloader
from panstamps.image import image
fitsPaths, jpegPaths, colorPath = downloader(
log=log,
settings=False,
downloadDirectory=False,
fits=False,
jpeg=True,
arcsecSize=600,
filterSet='gri',
color=True,
singleFilters=True,
ra="70.60271",
dec="-21.72433",
imageType="stack", # warp | stack
mjdStart=False,
mjdEnd=False,
window=False
).get()
for j in jpegPaths:
myimage = image(
log=log,
settings=False,
imagePath=j
arcsecSize=120,
crosshairs=True,
transient=False,
scale=True,
invert=False,
greyscale=False
).get()

ZOOLANDER A film review by Annette Cardwell Copyright 2001 filmcritic.com
In Zoolander, the world's most successful, influential and intellectually-challenged male model Derek Zoolander wonders, "Is there more to life than being really really really good looking?" Obviously, the film's creator and star Ben Stiller asked a similar question when crafting a feature-length movie out of his hilarious VH1/Vogue Fashion Awards short-film subject: Can there be more to this film than being really really really silly? No, of course not, and it never aspires to be anything more.
Much like Derek, Zoolander is a sweet simpleton of a movie. It's not complex in either its social commentary or its comedy, and it never produces any gut-busting laughs (except maybe a scene when Derek's model roommates all die in a tragic "gasoline fight" accident -- a riotously funny take-off of Tommy Hilfiger ads). But it has a satisfying handful of strong chuckles, wild characters and performances, and mildly harsh potshots at the fashion industry to keep you amused. Better yet, this exaggerated version of the original three-minute skit is only blown out to an efficient 95 minutes -- just enough time to string together its goofball plot without exhausting the gag.
Zoolander opens with several fashion bigwigs plotting to assassinate the Prime Minister of Malaysia, since he wants to abolish child labor in his country and thus driving up their costs. Fashion designer and criminal mastermind Jacobim Mugatu (Will Ferrell) drafts a plan to brainwash the dumbest fashion model to carry out the evil deed. Enter Derek, whose career is slumping as newcomer Hansel (Owen Wilson) takes the spotlight. On the trail of Mugatu's plot is Time magazine reporter Matilda Jeffries (Stiller's real-life wife Christine Taylor), and she's hoping to use Mugatu's pawn Derek to ultimately foil the scheme.
Much like the Austin Powers films, Zoolander relies heavily on the strength of the talent involved, and this zany comedy features some of the funniest people in entertainment today. Wilson is hysterical as the young, vain Hansel. Ferrell nearly steals the show from everyone as the flamboyant, freakish Mugatu in the same way Dr. Evil upstages everyone in Austin Powers. Jerry Stiller -- Ben's dad who's best remembered as Frank Costanza of Seinfeld -- makes a priceless turn as Derek's slimy agent Maury Ballstein. Even Ben Stiller Show alum Andy Dick shows up as a deranged, large-assed masseuse. As for Ben Stiller, it seems his Derek has one gag: He's stupid, which plays out in some uproarious one-liners.
Unfortunately, Taylor seems out of place and out of her league here. Maybe it's just because I can't stop seeing her as Marcia Brady (who she played in both Brady movies), making her unbelievable as a dowdy, brainy plain Jane who hasn't had sex in two years. She leaves me pining for the cynicism of Janeane Garofolo, who would've added real comic substance to the flimsy role.
While Zoolander is hardly highbrow, its screwball humor is welcome during these trying times, especially considering the gross lack of decent pickings in the theaters these days. Zoolander's no masterpiece, but a very worthy distraction.

Mesh: The Hackable IDE from the Future
Mesh is a programming environment that combines the best aspects of modern IDEs, the user-hackability of traditional text editors, the safety of pure functional programming languages, and the more progressive features of domain specific language workbenches into a cogent and elegant package. It's like Smalltalk, Emacs, Haskell, and Jetbrains MPS had a baby.
An editor that understands your code
The Mesh language and the Mesh editor are one in the same. This allows the editor to grok your code on a deep level, offering advanced autocomplete and code introspection out of the box. This also gives you the ability to customize the editor is some unique and powerful ways (detailed below). And don't worry - the code is all stored as text on disk, and can be run from the command line.
A safe, expressive language
The Mesh language is succinct, expressive, and modern. It features functions as first-class objects, a straightforward type system, a novel system for restricting access to global state and external IO, and out-of-the-box support for concurrency. It draws inspiration from Go, Erlang, Haskell, and Clojure, but differs from each in important ways.
Your program is an object
In Mesh, the program that you're building is actually just a regular old object. You can interact with it using the environment's REPL, allowing you to run arbitrary Mesh commands on it to gather information or perform alterations. This is incredibly powerful - instead of having to worry about all of the dangers inherent with making sweeping changes to regular text files, you can leverage the Mesh language's type- and state-safety to alter your program with confidence. And unlike refactoring tools in existing IDEs, Mesh allows you to easily roll your own from scratch and bind them to hotkeys. You can build up a vocabulary of safe, powerful alterations that allow you to generate code quickly and refactor boldly.
The editor is an object
Just as the program being built is a regular Mesh object that's available to the REPL, so too is the editing environment. This allows you to build ambitious extensions to the editor without having to learn another language like Vimscript or Emacs Lisp. What's even better is that you can make on-the-fly changes to the editor right from the REPL. And because you use the Mesh language for all modifications to the editor, you get that delicious type- and state-safety for free. When your environment is so easily modifiable, you'll be surprised how much you tailor it to fit the problem at hand.
The VM is an object
So, the program you're building is a Mesh object, and the editor is a Mesh object. And believe it or not, the Mesh VM itself is a Mesh object. To put it another way, you can programatically instantiate VM objects (either from the editor's REPL, or within your program itself) and then run arbitrary code on them. This allows you do some amazing things, like create custom live-coding and debugging environments; serialize the contents of a production VM and then reload it on your development machine to diagnose a problem; or mock out a VM's connections to the outside world to create an ideal test environment. Additionally, Mesh's VMs have robust mechanisms for talking to each other, which allows you to easily create concurrent and distributed programs.
Organize your code visually
While Mesh is not a "visual programming language", it does utilize a GUI to make it easier to navigate and view your program. Mesh's perspective system allows you to do things that are impossible in other editing environments: set up views that programatically query your program to display regions that match a specific criteria; pull up the tests for a function and view the two side by side with the tap of a key; or organize your code spacially in the same way you might lay out papers on your desk. And don't worry - you'll never need to touch your mouse while using Mesh.
Model your domain
Most large programs are comprised of two major parts: a declarative model of the concepts involved in the problem domain, and imperative code that turns that model into something that the user can interact with. Mesh makes it easy to create type-safe, declarative domain models, so that these two parts of your program can be cleanly separated. Modeling your program using declarative concepts is a huge boon - declarative concepts have no notion of time or state, which makes them much easier to reason about and change with confidence. Additionally, Because of Mesh's UI paradigm described above, you can also create concept-specific UIs for the domain models in your system, which means there's no syntax for you to remember. Why write it in text when you can just fill out a form?
Add safety as you go
As programs grow in complexity, there are more and more things that might go wrong. Tests are good for enforcing the functionality of imperative code, but are not so good at enforcing the structural integrity of the declarative portions of your program. Type checkers can be good for this, but they're limited (and trying to cram all of the correctness you need into the type system can be very confusing).  Because the Mesh program is a regular object, traversing it to look for problems is a cinch. And Mesh allows you to attach and display arbitrary metadata on any part of your program, so you can easily see the results of your checkers.

Use $((..))
for arithmetics, e.g. i=$((i + 2))
i=3
i=i+2
i=3
i=$((i + 2))
Unlike most languages, variable assignments (almost) always assigns strings and not expressions. In the example code, i
will become the string i+2
instead of the intended 5
.
To instead evaluate a mathematical expressions, use $((..))
as in the correct code.
If you wanted to assign a literal string, quote it:

ShellCheck (as of v0.5) doesn't recognize Bash/Ksh numeric variables created with declare -i
where this syntax is valid. Using $((..))
still works, but you can also [[ignore]] this warning.

Don't take my word for it. I have a lot of great feedback from people I have worked with as partners, managers and team members. You can also check out other references on upwork under Work History and feedback https://www.upwork.com/o/profiles/users/~014b27088d2e859ce3/
I recently gave two presentations at one of my client sites, Monkey Management and Trust in Project Management. Both of these are challenging topics in business. Monkey management discusses the organizational challenges when managers do not delegate responsibility to the teams they hire to do the work. When you establish trust in teams, it has a positive impact on the project as well as the well-being of the people in the team.
PMP and ITIL certified practitioner PMP demonstrates that you are capable of performing at the highest level in the field of project management. ITIL certification demonstrate that indicates individuals have demonstrated a knowledge about terms, processes, and other aspects of IT Infrastructure Library. Practical experience is important but it is rewarding to take courese and pass the certification tests.

This demo shows how to use the IAR-STM32F407ZG-SK board as
an embedded webserver. It is based on lwIP TCP/IP stack v1.3.2 and features
three HTML pages for interacting with the IAR-STM32F407ZG-SK board.
You will be able to control the four LEDs on
the board through the browser and you will be able to get
continuously, each 1 second, the ADC Channel 10 converted value displayed
on the web page of your browser. The demo can be
configured to use Static IP or DHCP at compile time. The address that is selected will
be shown on the on-board LCD display.
