This is a second in a series of posts describing our experience in migrating a large DWH server to TokuDB. This post discusses the process of migration itself.
As a quick recap (read part 1 here), we have a 2TB compressed InnoDB (4TB uncompressed) based DWH server. Space is running low, and we're looking at TokuDB for answers. Early experiments show that TokuDB's compression could make a good impact on disk space usage. I'm still not discussing performance -- keeping this till later post.
Those with weak hearts can skip right to the end, where we finally have a complete conversion. You can also peek at the very end to find out how much 4TB uncompressed InnoDB data is worth in TokuDB. But you might want to read through. The process was not smooth, and not as expected (it's a war story thing). Throughout the migration we got a lot of insight on TokuDB's behaviour, limitations, conveniences, inconveniences and more.
Disclosure: I have no personal interests and no company interests; throughout the process we were in touch with Tokutek engineers, getting free, friendly & professional advice and providing with input of our own. Most of this content has already been presented to Tokutek throughout the process. TokuDB is open source and free to use, though commercial license is also available.
How do you convert 4TB worth of data to TokuDB?
Obviously one table at a time. But we had another restriction: you may recall I took a live slave for the migration process. And we wanted to end the process with a live slave. So the restriction was: keep it replicating!
How easy would that be? Based on our initial tests, I extrapolated over 20 days of conversion from InnoDB to TokuDB. Even with one table at a time, our largest table was expected to convert in some 12-14 days. Can we retain 14 days of binary logs on a server already running low on disk space? If only I knew then what I know today :)
I recently claimed (as I recall it was in one of the @DBHangops meetings) I was done with ALTER TABLE statements. I would not touch them again: with oak-online-alter-table and pt-online-schema-change I can get better control of my server (and my sleep). Can I use an online migration tool?
Fortunately we are using Statement Based Replication on this MySQL topology. This makes for good news, because triggers are activated on slave as it is replicating its master's statements. You can run an online migration tool on the slave, while it keeps replicating. This is so cool. I don't need to worry too much about binary logs and relay logs. I can take my time with conversion...
I chose to use pt-online-schema-change. Why choose Percona's tool over my own? Percona's tool supports the --check-slave-lag option, which throttles the operation should the server's slaves start lagging. Wait, I'm running the tool on a slave, so what's the point? Well, you can cheat and provide --check-slave-lag=h=<IP_ADDRESS> so that the tool assumes the localhost is the slave (while it is actually the server being altered); which means it will check on its own slave lag to do the throttling. This works well and is fun to watch.
Starting the migration
Some of our tables had the KEY_BLOCK_SIZE explicitly declared. As I mentioned in previous post, for TokuDB <= 7.0.4 this causes problems by bloating the indexes instead of compressing them (and Tim Callaghan of Tokutek notes this is fixed in next version). common_schema to the rescue: the ALTER statement has to include a DROP and recreate of all indexes.
This is the place to mention our tables are heavily partitioned. This will play a crucial role in the next events. We use RANGE partitions over dates. We have a monthly partitioning scheme on all partitioned tables. And we have partitions to spare: starting a few years back from today (depending on the table) and made until Dec. 2025 -- making for some 170 - 200 partitions per table.
Starting from smallest table (a few rows) and increasing in size, we migrated tables one by one to TokuDB.
Party crashers
A few party crashers were made obvious right from the start (they are all being addressed by Tokutek as far as I know):
- @@datadir: all TokuDB files reside in @@datadir. You get a pile of files in the same directory where you would find your ib_logfile*, master.info, etc. files.
- File names: you do not get file names after table names. Instead, you get cryptic names like ./_myschema_sql_7fda_8e73_*.You would suspect that there is some uniqueness to the 7fda_8e73 thing; that it relates to a single table -- it doesn't. Same table get different file names, different tables get similar names -- there's not one regular expression to differentiate tables -- and I do know my regexes.
- INFORMATION_SCHEMA.Tokudb_file_map doesn't make it much easier, either. It is meant to tell you about tables to file names mappings. But the tables are not laid out in easy TABLE_SCHEMA, TABLE_NAME columns, but are denormalized themselves, and can be vague and almost ambiguous, to some extent. common_schema to the rescue, its rewritten tokudb_file_map maps your tables to aggregated list of file names, along with shell commands you would typically want to issue.
But let me emphasize these issues, before you think I'm just spoiled. TokuDB creates multiple files per table: other than the standard .frm file, you get one "main" file for each table, and then another file for each index. So it's quite possible your table will consist of some 7 files.
Well, as you may know, MySQL's implementation of partitioning is that each partition is made of its own standalone table, hidden from the user (but easily viewable on the filesystem). Now this means a single table with 170 partitions and a few indexes can make for over 1,000 files. That's right - for a single table. We have a few dozens like this.
Now consider:
- You may need to accommodate thousands or tens of thousands of files in your @@datadir
- None of which it is easy for you to know who to relate to.
So common_schema's tokudb_file_map gives you this crazy list of 1,000 files which make up your single table. This isn't too friendly, either.
I think Tokutek are missing here on one of the greatest advantages they bring to the table. The one thing a DBA want to know when looking at her MySQL's filesystem is: how much disk space is used by a schema/table. And this information becomes hard to get. Again, common_schema's view will provide you with the script to do it (du -c ... | tail -1) -- but you would have to go into MySQL, out to shell... Bother.
Crashes and failures
The above did not stop at inconveniences. Soon enough, and while still altering my smaller tables, I would get failures from pt-online-schema-change. Checking manually to eliminate the possibility of a bug in Percona's tool, I got:
mysql> alter table my_schema.my_table engine=tokudb row_format=tokudb_small; ERROR 1016 (HY000): Can't open file: './my_schema/#sql-80d_2.frm' (errno: 24)
This would happen again and again and again. What's the deal here?
Let me cut short on this one: we got over 20,000 files in @@datadir. And MySQL was unable to open any more files. Mind you, we had:
- open_files_limit=30000
- open_table_cache=16000
- table_definition_cache=3000
Quite the generous numbers (also backed up by ulimit, to be on the safe side; and also note we're using XFS file system). And yet, open files were an issue. To prove my point, it was possible to ALTER a table with a fewer number of partitions. It was then possible to ALTER another smaller table without partitions. It was then impossible to alter any additional partitioned table. Once I dropped partitioning for some very small table some room was made and I was again able to ALTER a partitioned table... And this would happen for completely empty tables -- no data involved. We were on some file limit here.
Another such ALTER and the server crashed. This was quite unceremonious. The error log produced nothing; no stack trace. Zit.
I was fervently querying the Tokudb_file_map to get a picture of what's going on. I would need to do a self join on the table (as common_schema's view does) to get a per-table listing of files. This would occasionally crash the server. I guess I had 3 or 4 such crashes.
Recovery
On this I feel I'm quite the veteran here :D. TokuDB recovery works well. As with InnoDB, TokuDB recognize there has been a crash, and before allowing MySQL to open connections it restores to a stable state.
ALTER TABLE in TokuDB
Here I found two comforting features (the third and fourth yet to be discovered). As indicated above, I did turn to issue a manual ALTER TABLE. What I found was:
- A TokuDB ALTER TABLE statement lets you know its progress. This is no little thing! Your SHOW PROCESSLIST output shows messages like "Fetched about 312724000 rows, loading data still remains", or "Loading of data about 66.1% done", or "Queried about 33113001 rows, Inserted about 33113000 rows". Cool!
- Even better, the crash I had during the ALTER TABLE? I thought that would be the end of it. If you ever had a crash while ALTERing an InnoDB table, you know how it goes: InnoDB will forever complain about some table existing but not listed (or the other way around). And don't get me started with DISCARD TABLESPACE; when InnoDB decides it is upset about something - you cannot convince it otherwise.
Thankfully, TokuDB completely reverted the ALTER operation. It removed what temporary files were created (further notes following) and forgot all about it. No complaints, no ghosts. Great! Back to consistency!
What do we do now?
Throwing my hands up in the air, having worked on this for many days, I thought to myself: OK, I still have this server all to myself. If TokuDB is not going to work out, I have some time to come up with a sharding/commercial solution. Let's use up this time and learn something about TokuDB. And I decided to re-create all tables without partitions. My colleague argued that she was not ready to give up on partitioning altogether and we decided to try again with YEARly partitioing scheme. This would reduce number of files by factor of 12. Also, 2025 is so far away, we agreed to settle for 2015. So reducing number of files by factor of 25-30.
And this made all the difference in the world. Having reduced number of files made the impact we were hoping for. Suddenly all went well. No crashes, no weird complaints, little proliferation of files in @@datadir.
ALTER TABLE
And I did notice that a manual ALTER TABLE went considerably faster than I would expect. And by far faster than the pt-online-schema-change pace. I tried a couple more -- sure thing. ALTERing a table from InnoDB to TokuDB is fast.
How fast?
- I converted a 47GB InnoDB COMPRESSED table to TokuDB in 73 minutes. By the way, resulting table size measured 3.4GB.
- A 330GB InnoDB COMPRESSED table converted to TokuDB took little over 9 hours. I dare you alter 600GB worth of uncompressed data into InnoDB (COMPRESSED) in less than a few days. It went down to 31GB.
- And our largest, 1TB COMPRESSED table (2TB worth of uncompressed data)? There's yet another story here.
Altering 1 (2 uncomressed) TB of data
Here's a tip that will save you some exhaustion: SET tokudb_load_save_space := 1.
While ALTERing our largest table, I was concerned to find our disk space was running low. Plenty temporary TokuDB files were created. I assumed these would consume only so much disk space, but to my surprise they accumulated and accumulated... It turns out for ALTERing a table TokuDB creates the equivalent of the table in temporary files, and only then generates the new table. This means you need to have enough room for your own original table, the equivalent in temporary files, and your new table altogether.
With great compression that would be nothing. However you'll be surprised to learn that by default those temporary files are not compressed. Thus, the ALTER operation consumed more than 1.3TB of disk space in temporary files, until I had no choice and (36 hours into the operation) had to KILL it before it consumed the entire 3TB of disk space.
Setting the variable as specified and the next attempt was far more successful: the temporary files were created with same compression algorithm as target table, which left with a lot of free space to work with.
ALTER time took about 40 hours.
Well, what's the resulting size?
 It took the better part of three weeks to work through all the pitfalls, the pt-online-schems-change attempts, the crashes, the tests, the no-partitions, the YEARly partitions... Finally we are with a TokuDB version of our data warehouse.
Suspension is over. We got from 2TB of InnoDB COMPRESSED (KEY_BLOCK_SIZE=8) down to 200GB of TokuDB_SMALL (aka agressive, aka lzma) tables.
I mean, this is beyond expectations. It is ridiculously small. From 80% disk space utilization down to 8% disk space utilization. Absolutely ridiculous!
Conclusions
- TokuDB does not play well with many partitions.
- Crashes encountered. Recovery is fine.
- Good ALTER TABLE experience
- SET tokudb_load_save_space := 1
- Great compression (x20 from uncompressed InnoDB; x10 from KEY_BLOCK_SIZE=8)
Next
In the following post I'll share some observations on how well our newly converted TokuDB slave performs as compared to our equivalent InnoDB slaves; some configuration you might care about; and some things you can do with TokuDB that would be so very painful with InnoDB. Stay tuned!

SABEN promotes broadband connectivity to improve teaching, learning and management at TVET colleges nationwide - update
SABEN has engaged the suppliers and TVET colleges in the detailed roll-out planning, with the first go-live connections expected in the first quarter of 2020.
by SABENThe TVET Campus Connection Programme (TCCP) is part of a renewed commitment by government to support TVET (Technical and Vocational Education and Training) colleges by providing high-speed, broadband connectivity for administration, teaching and learning.
In January 2019, the Access connection portion of the programme kicked off with a Request for Proposal (RFP) process. The requirement was to support the strengthening of broadband connections at 325 campuses across 50 TVETs. A number of achievements have been realised.
The RFP process has resulted in eight service providers being contracted to provide 200Mbps connections between the SANReN (South African National Research Network) and 223 campuses and to upgrade 51 already connected campuses from 100Mbps to 200Mbps per connection. Negotiations continue with TVETs regarding 18 campus connections. The remaining 33 campuses have been withdrawn from consideration for reasons such as merging of sites and lack of need.
From a technology perspective, the intention of the project was to minimise the wireless options and move towards fibre options, where cost-effective to do so. This is important in order to achieve a degree of ‘futureproofing’.
Preference was given to dark fibre, managed fibre and then wireless technology. Through the competitive RFP process, it was possible to provide a greater number of more reliable fibre connections than originally anticipated.
| Row Labels | Original Scenario | Final Scenario | Shift |
|---|---|---|---|
| Dark Fibre | 24 | 44 | 20 |
| Managed Fibre | 60 | 160 | 100 |
| Wireless | 157 | 37 | -120 |
| Grand Total | 241 | 241 | 0 |
The South African Broadband Educational Networks (SABEN) has engaged the suppliers and TVET colleges in the detailed roll-out planning, and this should be completed by mid-November 2019. The first go-live connections can be expected in the first quarter of 2020.
In addition to the abovementioned progress, it is important to note the inherent value that will be provided through these new and upgraded connections of the TVET campuses to the SANReN.
- The connections will provide a minimum of 200Mbps connection speed (where some of the connections being replaced are 5 and 10 Mbps ADSL connections);
- The connection speed will be upgradeable;
- The synchronous connections provide equal upload and download speeds;
- There is no data cap/limitation, contention, throttling or shaping on the connections; and
- SABEN provides a 24/7 call centre with real-time monitoring and management of the connections.
The essential characteristics of the SANReN are set out in the following diagram and associated notes:
The next phase of the TCCP will address WiFi for TVET campuses. A national survey of installed WiFi at the campuses of 48 TVET colleges was conducted in September and October 2019. The results of the survey will inform options for the project.
An ancillary component to the Access connection portion of the programme is the implementation of WiFi connectivity on all TVET college campuses. In planning this component, it became evident that there was insufficient knowledge about each TVET college campus for the TCCP team to create a viable WiFi implementation and deployment project plan.
To address this need, the TCCP team assembled a small team to visit each TVET college to collect information about the physical infrastructure of each TVET college’s network, WiFi infrastructure, if any, and capacity development needs.
The gathering of the information was called the TCCP TVET Technical Census. A questionnaire was developed and loaded on to tablets, and the TCCP census takers entered answers to the set of questions into a tablet. At the end of the question session with a TVET, the answers were uploaded to the cloud.
The answers will then be pooled and analysed, and used to provide a viable and meaning WiFi deployment plan and a capacity development plan.
It will take about two months to gather the data and a further month to analyse the data and write a WiFi and capacity deployment plan.

Inaccurate Almanacke
This week over at The Dabbler I am afraid I have had to issue a set of corrections and clarifications to Old Key's Almanacke for 2011. As I point out, the errors in the original were probably due to the wrong kind of ectoplasm on the line, the “line” in this case being an invisible thread strung between the corporeal world and the eldritch realms inhabited by the shade of Old Key himself.
The mysterious prognosticator can, however, already claim a triumph of foresight in the first week of the year. Old Key noted that birds fall out of the sky when petulant Ozymandias, King of Kings, gets one of his temper tantrums, and what do we find? In Arkansas, blackbirds have plummeted from the blue, while flocks of jackdaws have crashed to earth in Sweden.


public class BufferedReader extends Reader
Reader
and buffers the input. Expensive interaction with the underlying reader is
minimized, since most (smaller) requests can be satisfied by accessing the buffer alone. The drawback is that some
extra space is required to hold the buffer and that copying takes place when filling that buffer, but this is usually
outweighed by the performance benefits.
A typical application pattern for the class looks like this:

Defunct Ideal Finance boss Kotei Dzani arrested
The CEO of defunct Ideal Finance Nii Kotei Dzani was on Wednesday arrested by the police for misappropriation of some funds in his care.
Reliable sources told Starrfm.com.gh that the Council of State member was detained at the Ministries Police Station for some hours before being released on bail.
Sources say he was arrested over the misappropriation of some GHc 1,000,000.00 entrusted to him during the operation of his financial outfit.
Sources within the Police service indicate that one of the clients of his collapsed Ideal Finance may have dragged the elected member of the Council of State to the Police in an attempt to retrieve monies owed him.
“We have granted him bail and we are investigating the case,” a top police official said.

So I got a car. Well, we got a rented car. I had been somehow nervous seeing the day coming closer and closer and not doing anything, but getting more nervous. So on tuesday we decided to finally get rid of this pain. After a really nice italian lunch under some trees as umbrella and an improvised siesta (the heat was really pushing us to the couch) we sat in front of the computer and started scooping rental car websites. After a while, a few shocks due to the numbers we were seeing and some deeper search, we came out with the final choice: a Chevrolet from Alamo through a british web-operator :) I guess it couldn't have been anything better than a Chevie for my Coast2Coast.


title: Bubble Chart
A bubble chart is used to display three dimensions of data at the same time. The location of the bubble is determined by the first two dimensions and the corresponding horizontal and vertical axes. The third dimension is represented by the size of the individual bubbles.
// For a bubble chart
var myBubbleChart = new Chart(ctx,{
type: 'bubble',
data: data,
options: options
});
| Property | Type | Usage |
|---|---|---|
| data | Array<BubbleDataObject> |
The data to plot as bubbles. See Data format |
| label | String |
The label for the dataset which appears in the legend and tooltips |
| backgroundColor | Color Array<Color> |
The fill color of the bubbles. |
| borderColor | Color or Array<Color> |
The stroke color of the bubbles. |
| borderWidth | Number or Array<Number> |
The stroke width of bubble in pixels. |
| hoverBackgroundColor | Color or Array<Color> |
The fill color of the bubbles when hovered. |
| hoverBorderColor | Color or Array<Color> |
The stroke color of the bubbles when hovered. |
| hoverBorderWidth | Number or Array<Number> |
The stroke width of the bubbles when hovered. |
| hoverRadius | Number or Array<Number> |
Additional radius to add to data radius on hover. |
An example data object using these attributes is shown below. This example creates a single dataset with 2 different bubbles.
var data = {
datasets: [
{
label: 'First Dataset',
data: [
{
x: 20,
y: 30,
r: 15
},
{
x: 40,
y: 10,
r: 10
}
],
backgroundColor:"#FF6384",
hoverBackgroundColor: "#FF6384",
}]
};
Data for the bubble chart is passed in the form of an object. The object must implement the following interface. It is important to note that the radius property, r
is not scaled by the chart. It is the raw radius in pixels of the bubble that is drawn on the canvas.
{
// X Value
x: <Number>,
// Y Value
y: <Number>,
// Radius of bubble. This is not scaled.
r: <Number>
}
The bubble chart has no unique configuration options. To configure options common to all of the bubbles, the point element options are used.
For example, to give all bubbles a 1px wide black border, the following options would be used.
new Chart(ctx,{
type:"bubble",
options: {
elements: {
points: {
borderWidth: 1,
borderColor: 'rgb(0, 0, 0)'
}
}
}
});
We can also change the default values for the Bubble chart type. Doing so will give all bubble charts created after this point the new defaults. The default configuration for the bubble chart can be accessed at Chart.defaults.bubble
.

Happy new year and we start again with our monthly meetups in 2014.
Talks
"Using Vimperator to browse the Web" by Matthias Günther
I switched over to Vimperator one month ago and would like to show you shortcuts and how you can configure it.
"Using Vimperator to browse the Web" by Matthias Günther from wikimatze on Vimeo.
"Clever autocommands" by Andrew Radev
I'm going to do a quick overview on autocommands and some gotchas in their usage. I assume that most people present will know this stuff already, but there might be one or two things you may not have known before :).
I'll talk about some clever ways I use autocommands. I'll also show my unfinished experiments with a recently-added autocommand called
TextChanged
. This allows you to hook into any kind of change in both normal and insert mode, with some gotchas...I'm hoping that many other attendees will pitch in for ideas about interesting autocommands they use, opening up some discussion after the talk.
“Clever autocommands” by Andrew Radev from wikimatze on Vimeo.
"Writing text in Vim" by Florian Eitel
I like to show some tricks and snippets I use for working with text. This include using the spell checker in multiple languages, break long lines, full text search using vimgrep and maybe more.

# Product workflow How to be a production ready team
Summary
- #### Git workflow - #### Semantic versioning - #### Commit semantic - #### In practice
Git workflow
#### develop and master * Master branch is the release history. Every commit is tagged. * Develop branch is the integration branch of features.
#### develop and master ![workflow-master-develop](./img/workflow-master-develop.svg "Master-develop workflow")
#### feature branch * feature branch should be created from develop * feature branch should be merged into develop * feature branch MUST not interact with master * feature branch should be named feature/ID-FEATURE Example: feature/12-my-feature
#### feature branch ![workflow-feature](./img/workflow-feature.svg "Feature workflow")
#### bugfix branch A bugfix is the correction of a bug present in develop and not in master * bugfix branch should be created from develop * bugfix branch should be merged into develop * bugfix branch MUST not interact with master * bugfix branch should be named bugfix/ID-BUG Example: bugfix/13-my-bugfix
#### release branch - release branch should not accept new features once created - release branch MUST be merged into master - release branch MUST be merged into develop - release branch branch should be named release/VERSION Example: release/1.0.1
#### release branch ![workflow-release](./img/workflow-release.svg "Release workflow")
#### hotfix branch A hotfix is the correction of a bug present in master - hotfix branch should be created from master - hotfix branch MUST be merged into master - hotfix branch MUST be merged into develop - hotfix branch should be named hotfix/ID-BUG Example: hotfix/14-my-hotfix
#### Synthesis ![complete-workflow-git](./img/workflow-git.svg "Complete workflow")
Semantic versioning
#### [Semver](https://semver.org/) It is a convention that describes how product/package versioning should be done * 1.0.0 => 1.0.1 : patch version (only fixes) * 1.0.1 => 1.1.0 : minor version (fixes and features) * 1.1.0 => 2.0.0 : major version (breaking changes)
#### Breaking changes What is a breaking change ? > A change in one part of a software system that potentially causes other components to fail Examples - changes in injection data API - changes in generated API contract - non upgradable changes in database - changes in app removing a feature
Conventional commits
It is a [convention](https://www.conventionalcommits.org) that describes some rules for writing commit ```
[optional scope]:
[optional body] [optional footer] ``` Example : Commit with body and issue link in footer ``` fix: minor typos in code see the issue for details on the typos fixed fixes issue #12 ```
##### type * feat, fix : tracked and used for changelogs * chore, docs, style, refactor, perf, test : can be used, not tracked ##### scope The scope is the perimeter of the commit * -engine => worker, engine, docs, dqapi... * -api => api, consumer,...
#### Examples Simple commit ``` docs: correct spelling of CHANGELOG ``` Simple commit, with scope ``` feat(lang): added polish language ``` Commit with breaking changes ``` feat: allow provided config object to extend other configs BREAKING CHANGE: `extends` key in config file is now used for extending other config files ```
#### Why * Consistency * Readability * Complementary with [Semantic versioning](https://semver.org/) * Allows automatic generation of changelogs * Allows easier writing of upgrade documentation
![changelog](./img/changelog.png "Changelog")
In practice
#### Branches - Respect branch naming - Branch across multiple repos for a same feature must have the same name, and be linked to the same issue - One branch = One feature OR fix - While doing a feature, if I see a bug/codestyle unrelated, I must do it on another branch
#### Merge request - Merge request will be fast-forwarded, and can be squashed - Branch to merge, if not squashed, MUST have clean commit (`git rebase -i`) - Merge request must have 2 reviewers - Reviewer must enforce several things - Code style (no copy-paste, readability, no useless variables, or assignement...) - Feature (content, limit case handling, unit test, ...) - Linting (branch naming + commit style)
#### Automation - Git hooks will enforce these behaviours, both for learning and consistency purposes - locally - on CI - Release task will be automated - One task for multiple repositories - Separated and aggregated changelog - Gitlab release
#### Example : Add ensembling to monitor (1/3) - Create feature branch (linked to issue if possible) - `git fetch --prune` - `git checkout -b feature/42-add-ensembling-monitor origin/develop` - `git push --set-upstream origin feature/42-add-ensembling-monitor` - Create Merge Request in WIP (Work In Progess) with title `feat(monitor): adding ensembling (fixes #42)`
#### Example : Add ensembling to monitor (2/3) - Do some work - `git commit -m "feat(monitor): adding ensembling"` - `git commit -m "refactor(monitor): cleaning up code"` - `git push` - Rebase regularly on `develop` - `git fetch --prune` - `git rebase origin/develop` - `git push --force-with-lease`
#### Example : Add ensembling to monitor (3/3) - Ask for review when ready and remove WIP - Two options - Squash commits using option in MR options (commit message will be MR title) - Clean up your commits and do a fast-forward merge - `git rebase -i HEAD~5` ou `git rebase -i origin/develop` - `git push --force-with-lease`
#### Example : Hotfix queue name (breaking training) Same as feature, except - Branch must be checkout from `master` - Two MR must be created, one for `develop`, one for `master` - Branch must be named `hotfix/43-fixing-queue-name` - MR title should be `fix(engine): fixing queue names (fixes #43)` - Commit type should be fix `fix(engine): restoring old queue names`

Among Giants (1999) A Capsule Review by Nathaniel R. Atcheson
Director: Sam Miller Cast: Pete Postlethwaite, Rachel Griffiths, James Thornton Screenplay: Simon Beaufoy Producers: Stephen Garrett Runtime: 94 min. US Distribution: Fox Searchlight Pictures Rated R: language, sex, nudity
Copyright 1998 Nathaniel R. Atcheson
Visually interesting but emotionally vacuous, Sam Miller's Among Giants stars Pete Postlethwaite as a painter who falls in love with a tomboy (Rachel Griffiths). Postlethwaite and Griffiths are both good, but the love story is too inconsequential to gather any kind of momentum (and the film is far too short to develop the characters adequately). There's also an extended scene in the middle that features gratuitous frontal nudity of both characters, and it's more likely to elicit laughs than anything else. But Among Giants is still very pretty to look at, thanks to Miller's majestic direction, and the colorful group of supporting characters is at least marginally interesting.

Steam Achievements Tracker
Steam Achievements Tracker
This is a mobile app built upon the Flutter framework that uses the Steam API. Given a Steam User’s vanity URL, it orders all their owned games by percentage of achievements completed in descending order (it filters out games with 100% achievement completion).
The goal of this app is to provide a simple way to see which games are closest to 100% achievement completion for who care about such things, similar to the built in badge progress in the Steam UI.
Getting Started
Prerequisites
Flutter: Get it here
The Android SDK should also be installed: Get it here An android emulator will be needed to run the app locally
Installing
Before running the program, a valid Steam APIkey should be entered into ‘configs.dart’. A Steam API key can be gotten from the Steam Dev Portal
NOTE: Your Steam API key is extremely sensitive and should be kept secret. Any commits/PRs that include this value will be rejected
Additional Note: The Steam Profile you are attempting to pull data from must be set to public. See here for a Steam Knowledge Base article on privacy settings
Built With
- Flutter - The Mobile App Framework


Errors & Warnings
[Description]
Note: Your code for each level is saved in your browser.
You solved the level in seconds.
You can predict the future of the system by calling simulate(dt, controlFunc) on the model state. Example:
// Simulates for 0.5 seconds. The input for the model is set to be the negative of its `x`. newState = state.simulate(0.5, function(s){ return -s.x ;})
simulate() returns a modified copy of the model state.
The control function will be evaluated only once at the start of a simulate() call
and held constant during the simulation, so choose a small dt.
You can view your own variables by calling `monitor(name,value)`.
If you need to, you can use global variables.
You will have to declare them outside your function with the 'var' keyword.

[dscrdeql] <Combat Wom-mod>
[dscrdeql] <Jellysmash> I think once there's a house or two built, like a demo house and people can see what they're gonna be buying then that type of thing will make a difference
[dscrdeql] <Jellysmash> There'll be proof in the puding
[dscrdeql] <Jellysmash> when people can see what awesome houses can be built and the price of them then they'll understand
[dscrdeql] <Jellysmash> and queue up to get one of them
[dscrdeql] <Jellysmash> I know they're working on it, just a matter of time
[dscrdeql] <Jellysmash> not sure how long it takes to make one of them
[dscrdeql] <Jellysmash> I watched the video and it looks fairly straight forward
[dscrdeql] <Jellysmash> maybe in a few weeks
[dscrdeql] <Jellysmash> I'm really looking forward to seeing this progress
[dscrdeql] <Jellysmash> it's going to be fantastic
[dscrdeql] <Jellysmash> It'd be like a demo house like they have in Australia where you go to one of those housing demonstration villages
[dscrdeql] <Jellysmash> each building company has a few houses so you can see the design and what they're like
[dscrdeql] <Jellysmash> a lot of people find it hard to visualise that sort of stuff
[dscrdeql] <Jellysmash> but when they see it in reality, they'll love it
[dscrdeql] <Combat Wom-mod> yeah i agree.. i don't think they are waiting on building but getting the right permissions to build
[dscrdeql] <Jellysmash> that's why those demo homes are so important to the bvjuilding industry
[dscrdeql] <Jellysmash> I guess they have to buy a block of land first and then get the building permissions and the build according to the council regulations and building codes and compliance.
[dscrdeql] <Jellysmash> that's stuff can take time
[dscrdeql] <Jellysmash> especially in australia
[dscrdeql] <Jellysmash> just getting a council approval in sydney takes months
[dscrdeql] <Jellysmash> to do even the most simplest modification
[dscrdeql] <Jellysmash> I'm sure other countries aren't so long
[dscrdeql] <Jellysmash> but where ever there's regulations you can guarantee it takes time
[dscrdeql] <Combat Wom-mod> yeah i think thats why beginning in PR is a better idea
[dscrdeql] <AndronicusBass-Founder> We will build a few types, I plan to build one of my own here in AUS, I used to like the idea of shipping containers but they get crazy hot especially in SA. Energy efficient is a key property of the homes.
[dscrdeql] <Jellysmash> I saw the video and it was amazing...looked so easy
[dscrdeql] <Jellysmash> and cheap..
[dscrdeql] <Jellysmash> they said about $2000
[dscrdeql] <Jellysmash> but that'd be USD so about $2700 aussie
[dscrdeql] <Jellysmash> but for a house, that's incredible
[dscrdeql] <Jellysmash> I guess fitting it out with taps, toilets, etc may cost another $5k as that can be one of th emost costly bits and pieces
[dscrdeql] <Combat Wom-mod> that would be nice... costs you more to do some landscaping here lol
[dscrdeql] <Jellysmash> hahaha...yes
[dscrdeql] <AndronicusBass-Founder> What is $2000?
[dscrdeql] <Jellysmash> I got a back deck built at my last house...cost $10k
[dscrdeql] <Jellysmash> I saw in the youtube video by that building company..in was in a link on the Equaliser official twitter site.
[dscrdeql] <Jellysmash> can't remember their name
[dscrdeql] <Jellysmash> but the video showed the technology behind how they build the houses and how light the aircrete is and how strong also
[dscrdeql] <Jellysmash> and super easy to pour into a frame and mix up
[dscrdeql] <Jellysmash> that video was an eye opener
[dscrdeql] <micaine10> Hello
[dscrdeql] <Combat Wom-mod> yeah the aircrete homes
[dscrdeql] <AndronicusBass-Founder> indeed
[dscrdeql] <Combat Wom-mod> forget the name but i checked out their site.. really nice
We have also secured a working partnership with Domegaia founder Hajjar Gibran to create sustainable housing at fractions of the cost of traditional construction see this home built for less than 10k!!! https://t.co/1ppFFkFzzS

Small, fast, and highly energy-efficient memory device inspired by lithium-ion batteries
| Source: | Tokyo Institute of Technology |
| Summary: | Scientists have developed a new three-valued memory device inspired by solid lithium-ion batteries. The proposed device, which has an extremely low energy consumption, may be key for the development of more energy-efficient and faster random-access memories (RAMs), which are ubiquitous in modern computers. |
Virtually all digital devices that perform any sort of processing of information require not only a processing unit, but also a quick memory that can temporarily hold the inputs, partial results, and outputs of the operations performed. In computers, this memory is referred to as dynamic random-access memory, or DRAM. The speed of DRAM is very important and can have a significant impact in the overall speed of the system. In addition, lowering the energy consumption of memory devices has recently become a hot topic to achieve highly energy-efficient computing. Therefore, many studies have focused on testing out new memory technologies to surpass the performance of conventional DRAM.
The most basic unit in a memory chip are its memory cells. Each cell typically stores a single bit by adopting and holding one of two possible voltage values, which correspond to a stored value of either "0" or "1." The characteristics of the individual cell largely determine the performance of the overall memory chip. Simpler and smaller cells with high speed and low energy consumption would be ideal to take highly efficient computing to the next level.
A research team from Tokyo Tech led by Prof. Taro Hitosugi and student Yuki Watanabe recently reached a new milestone in this area. These researchers had previously developed a novel memory device inspired by the design of solid lithium-ion batteries. It consisted of a stack of three solid layers made of lithium, lithium phosphate, and gold. This stack is essentially a miniature low-capacity battery that functions as a memory cell; it can be quickly switched between charged and discharged states that represent the two possible values of a bit. However, gold combines with lithium to form a thick alloy layer, which increases the amount of energy required to switch from one state to the other.
In their latest study, the researchers created a similar three-layer memory cell using nickel instead of gold. They expected better results using nickel because it does not easily form alloys with lithium, which would lead to lower energy consumption when switching. The memory device they produced was much better than the previous one; it could actually hold three different voltage states instead of two, meaning that it is a three-valued memory device. "This system can be viewed as an extremely low-capacity thin-film lithium battery with three charged states," explains Prof. Hitosugi. This is a very interesting feature that has potential advantages for three-valued memory implementations, which may be more area efficient.
The researchers also found that nickel forms a very thin nickel oxide layer between the Ni and the lithium phosphate layers, and this oxide layer is essential for the low-energy switching of the device. The oxide layer is much thinner than that of the gold-lithium alloys that formed in their previous device, which means that this new "mini-battery" cell has a very low capacity and is therefore quickly and easily switched between states by applying minuscule currents. "The potential for extremely low energy consumption is the most noteworthy advantage of this device," remarks Prof. Hitosugi.
Increased speed, lower energy consumption, and smaller size are all highly demanded features in future memory devices. The memory cell developed by this research team is a very promising stepping stone toward much more energy-efficient and faster computing.

https://en.wikipedia.org/wiki/Monte_Carlo_method
https://en.wikipedia.org/wiki/Markov_chain_Monte_Carlo
https://en.wikipedia.org/wiki/Metropolis%E2%80%93Hastings_algorithm
'Monte Carlo methods' are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. Monte Carlo methods are mainly used in three problem classes: optimization, numerical integration, and generating draws from a probability distribution.
Monte Carlo methods vary, but tend to follow a particular pattern:
(1) Define a domain of possible inputs.
(2) Generate inputs randomly from a probability distribution over the domain.
(3) Perform a deterministic computation on the inputs.
(4) Aggregate the results.
Monte Carlo method applied to approximating the value of pi.
(1) Draw a unit square, then inscribe a quadrant within it.
(2) Uniformly scatter a given number of points over the square.
(3) Count the number of points inside the quadrant.
(4) The ratio of the inside-count and the total-sample-count
is an estimate of the ratio of the two areas, pi/4.
Multiply the result by 4 to estimate pi.
Uses of Monte Carlo methods require large amounts of random numbers, and typically pseudorandom number generators are used.
Markov chain Monte Carlo (MCMC) methods comprise a class of algorithms for sampling from a probability distribution. By constructing a Markov chain that has the desired distribution as its equilibrium distribution, one can obtain a sample of the desired distribution by recording states from the chain. Various algorithms exist for constructing chains, including the Metropolis-Hastings algorithm.
Warning. The random samples used in MCMC are autocorrelated.
The Metropolis-Hastings algorithm is a Markov chain Monte Carlo (MCMC) method for obtaining a sequence of random samples from a probability distribution from which direct sampling is difficult. This sequence can be used to approximate the distribution (e.g. to generate a histogram) or to compute an integral (e.g. an expected value).
The Metropolis-Hastings algorithm can draw samples from any probability distribution P(x), provided that we know a function f(x) proportional to the density of P(x) and the values of f(x) can be calculated. The algorithm works by generating a sequence of sample values in such a way that, as more and more sample values are produced, the distribution of values more closely approximates the desired distribution P(x). These sample values are produced iteratively, with the distribution of the next sample being dependent only on the current sample value. Specifically, at each iteration, the algorithm picks a candidate for the next sample value based on the current sample value. Then, with some probability, the candidate is either accepted or rejected. The probability of acceptance is determined by comparing the values of the function f(x) of the current and candidate sample values with respect to the desired distribution P(x).
Problem: the samples are correlated. We have to throw away the majority of samples and only take every nth sample, for some value of n.
Problem: the initial samples may depend on the initial point. A 'warmup' period is typically necessary, where an initial number of samples are thrown away.

This is a demonstration of step one "barely-counts" Reactive, from Understanding Reactive Programming.
Now please open your browser's developer's tools (usually f12, cmd-opt-i, or ctrl-shift-i, varying by browser and OS,) then switch to the console.
By example, to get started, you might copy and paste
var A = 0,
B = 5,
X = new JRV( () => A+B );
console.log( X.v );
A = 10; console.log( X.v );
A = 20; console.log( X.v );
A = 30; console.log( X.v );
That should, successively, print 5, 15, 25, and 35.
Can you predict what this code will do?
function SumOfArray(A) { return A.reduce( (x,y) => x+y ); }
function ArrayAsTextString(A) { return A.map(num => num.toString()).join(', '); }
function RandBetween1and10() { return Math.floor(Math.random() * 10) + 1; }
var List = [],
Sum = new JRV( () => SumOfArray(List) ),
Text = new JRV( () => ArrayAsTextString(List) );
window.setInterval( () => {
List.push(RandBetween1and10());
console.log( `Sum ${Sum.v} from [${Text.v}]\n` );
}, 1000 );
Reload the page if the console is getting boringly long.

Hudson makes extensive use of generics. Thus it has to be compiled with JDK 1.5. There is no possibility of removing the generics from the code as it is too well integrated.
Up until builds in the 1.90ish area, the Hudson build process would use retrotranslator to backport the Hudson to work on JDK 1.4. However, retrotranslator is not perfect. It does not catch every case where you have used a method that was introduced in JDK 1.5. Very often, it would take a couple of days before somebody would catch the problem.
Basically, using retrotranslator was a patch over the seeping wound at best. So retrotranslator was dropped, and you must run Hudson with JRE 1.5.
To make things more fun, there is a bug in JDK 1.5 to do with generic exceptions, so Hudson needs to be compiled with JDK 1.6. Thankfully, this is just a compilation requirements and not a runtime requirement, so we can run Hudson with JDK 1.5)
The Maven2 project type (alpha) uses Maven in a semi-embedded mode, therefore, it must run Maven in the same JRE (as far as I know).
Building with JDK5 and deploying to JDK1.4 (or earlier) is quite possible, but if you'd like to use compiler from the earlier version of JDK, or to run unit tests with the target JVM, you can do as follows:
In your ~/.m2/settings.xml put a ,
<properties> <jdk.ibm.1.4.2.path>c:\jdks\ibm-1.4.2\</jdk.ibm.1.4.2.path> <!-- or whatever your local path is --> <!-- if windows --> <jdk.ibm.1.4.2.jvm>${jdk.ibm.1.4.2.path}bin\java.exe</jdk.ibm.1.4.2.jvm> <jdk.ibm.1.4.2.javac>${jdk.ibm.1.4.2.path}bin\javac.exe</jdk.ibm.1.4.2.javac><!-- if windows --> !-- if *nix --> <jdk.ibm.1.4.2.jvm>${jdk.ibm.1.4.2.path}bin\java</jdk.ibm.1.4.2.jvm>< <jdk.ibm.1.4.2.javac>${jdk.ibm.1.4.2.path}bin\javac</jdk.ibm.1.4.2.javac><!-- if *nix --> </properties>
Then change your project's pom.xml such that you have something like
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <verbose>true</verbose> <fork>true</fork> <executable>${jdk.ibm.1.4.2.javac}</executable> <compilerVersion>1.4</compilerVersion> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <jvm>${jdk.ibm.1.4.2.jvm}</jvm> <forkMode>once</forkMode> <!-- can also use always. Cannot use never --> </configuration> </plugin>
You might also consider adding the enforcer plugin to stop the build if the properties are not set or if the compiler and jvm don't exist.
Note: I have not tested this, the need for the .exe's on windows may not exist. Give it a try and update this page when you have something that works (if my initial guess is incorrect)

--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/system-wide.20elan.html ---
@Sebastian Ullrich I'd like to try to build a debian package for local deployment for my course. Is it possible to have a system-wide elan
It seems elan always tries to install in the user directory
Or should I forget about elan and install Lean directly?
You can do a system-wide installation of elan manually - here is Arch Linux's package for rustup for comparison: https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/rustup#n30
Is there a command line argument for elan saying where it should install?
But if you're using a single Lean version for your course, there's probably not much to benefit from elan
That's probably simpler indeed. Maybe releasing Lean 3.4.2 would also make it feel cleaner
Yes, I hope I can get to that today
Thanks

How to Engage Students
1. Practice your stand-up routine. It doesn't matter if they are six or sixteen, everyone loves to laugh. Try to interject some humor into your lessons.
2. Use a variety of technology. You are teaching to children that have been spoon fed mass media from an early age. Accept this, keep up with technology, and go for it.
3. Provide hands-on experiences, allow exploration - supplement "book learning."
4. Shock, drop and roll. Gain their attention with extreme facts. Think Guinness World Records TM and relate it to your subject, drop anecdotes, and if this fails, roll with it and return to step one. 5. Let them learn from each other. The ability to learn a concept is increased by trying to teach it to someone else. Encourage peer tutoring and coaching.

Thanks man. ---
Richard Seroter has a few good recommendations here on how to diagnose the confusing "Internal SOAP Processing Failure" message you get when a call to a WebService exposed from BizTalk fails. As he mentions, it can be quite confusing and sometimes quite hard to get to the root of the cause if you're not familiar with the system.
Other recommendations I'd add to Richard's list would include:
Besides this, I always recommend developers that any orchestration that is going to be exposed as a Web Service should have extremely strong error handling built-in, hopefully to ensure it always returns a response message (either a real response or a failure message). Otherwise, an unhandled exception will cause the orchestration instance to be suspended which will cause the Web Service to timeout.
