Introduction
Everyone is welcome
You won't need any mods, just the latest non-dev version of ArmA 3 (including the APEX expansion) and TeamSpeak 3. There are no applications or tests. We only ask that you read through our introductory information.
Click on The Basics button bellow to get started...
The BasicsThe Basics
Uh, hello?
Welcome, comrade! The Third International Fighting Brigade of Takistan in the name of Che Guevara is overjoyed to have you with us. I can see that you are ready to charge off into action. Unfortunately, you will have to curb your enthusiasm for a bit, as our scheduled operations do not begin before 1920 UK time, every Sunday and Tuesday.
The what now?
The sessions, of course! Twice a week, we will embark on a mix of Coop and PvP missions. Generally, they are affairs of 20-50 organized, focused individuals, who can be relied on to bring them to a close within 40 min, without resorting to revive or third person.
Oh, yeah, the sessions. That's what i came here for. What are the requirements for joining up?
To attend, you will need the latest (official, stable, non beta version of) Arma 3, and (the latest stable, non beta version of) TeamSpeak 3. The Arma 3 DLC is not strictly required, but players who don't have the APEX expansion will not be able to participate in missions set on Tanoa. There are also no required addons. There is a small list of optional addons, but they are, as the name says, optional.
So that's for "attending". What if I want to join?
There is no "joining" process in FA. Everyone is welcome to hop on and play. There is also no saluting, no ranks, and the slots are handed out on a 'first come-first served' basis, and you can take any slot the host calls out, be it commander, tanker, pilot, or the common grunt.
That's cool!
Yes it is.
Wait, there are no ranks, but there's a commander?
Exactly. Anyone can step up to command, anyone can step up to be a grunt. But whatever slot you pick for the mission, stick to it. If you're a rifleman, do what your unit lead tells you. If you're a unit lead, do what your commander tells you. If you're a commander, devote your time to actually commanding. ArmA works best as a team sport. Folk ARPS believes you don't need ranks to be a team.
But what if I screw up?
 Like most other things in FA, competence is entirely optional. Your comrades will not feel less of you for trying. Or else.
Uh...
But enough about un-pleasantries. Step right on to the next room, while we walk you through the standard setup:
Showing up
So, first of all, before you join, you should probably set up your Teamspeak client
How do I set up Teamspeak?
For starters, if you don't already have it, download the latest version of TS3 from their website and install it. Once it's installed, launch it and connect to server.folkarps.com:9988. The password is freedom. You will be connected to "General Chat", at the very bottom of the list. For the session, move to "Limbo", at the very top of the list. Next, you should probably join the game server.
How do I join the ArmA 3 server?
In the ArmA 3 Launcher that starts when you launch the game from Steam, go to SERVERS, then INTERNET, then search for 'folk' (it may take couple of minutes). Of the two servers found, select the "Folk ARPS" server and click "join". The password is "freedom".
The server just kicked me.
Yeah, that tends to happen if you have non-authorized mods. Close the game, disable any non-authorized mods (or, as a last resort, all mods) and try again.
Ok, I'm in. What now?
Now we wait for the host to pick a mission. Once everyone is in the Limbo channel and on the game server, the Host load up a mission and begin calling slots. For example, the Host will call for a Commander, and open the CO slot. Whoever takes the slot is the commander for the duration of the mission. Next he will call the SL, then FTL etc. Once everyone is slotted, the session Host will launch the mission, ask you to move to a different Teamspeak channel, which will be used for the duration of the mission.
So how do the actual missions work?
Once the mission is launched, you will see the briefing screen, and should move any banter to the sidechat (press '/' to type, press 'enter' to send). This gives the CO time to read the briefing and think of a plan in peace. It's a good idea to read the briefing yourself. When the CO is done planning, he will then share his plan with the rest of the platoon, and the mission will start. When If you get killed, return to Limbo, and once the mission ends, the Host loads the next mission, and the slotting starts again.
Hold on. If just anyone can join, then how do you keep out the... how to put this... more disruptive people from ruining the sessions?
The Host team has methods of enforcing etiquette
The, uh, the etiquette?
Oh, that's right, how (ironically) rude of me! Step right into the next room:
EtiquetteEtiquette
So, what is the etiquette?
We ask that every comrade observes a few very simple principles with regard to communications, gameplay and banter:
- Slotting: During this phase please don't talk on TS and listen carefully to the host's instructions. Please use SideChat for questions and banter.
- Briefing: During this phase please don't talk on TS and listen carefully to the CO's instructions. Please use SideChat for banter. Importantly, we don't plan by committee: critiques and alternative plans belong in the session's AAR thread.
- In-Game: Simply remember that one person's witty banter can be another's frustrating distraction. Some banter on VON is fine, but if an element leader asks you to hush for a bit, please do so.
That seems reasonable. What about during gameplay?
If you do only one thing, simply to follow the orders of your element leader and avoid lone-wolfing. Beyond that, we like to respect the design of each scenario and play the parts we have selected during slotting: unless ordered to, please don't scavenge for fancy/different weapons or vehicles not relevant to your role. Non-regulation gear tends to attract friendly fire and falling submarines.
What?!?
Nevermind. Just follow the etiquette and keep the banter to chat during planning.
Is, uh, is there an etiquette guide for banter?
Just one rule: please don't use humour that is at the expense of any group of people, be it defined by gender, race, sexual orientation, nationality, political views etc. At FA, everyone is welcome - because we all strive to ensure nobody feels unwelcome. We're sure you already know that outright sexism, racism, homophobia etc. are unacceptable here (as in many communities) - we just ask that when you crack a joke or make a witty comment, you consider first whether it will make someone feel unwelcome. If your remark boils down to 'lol, gay'/'lol, swedes'/'lol, rape', then it's just not our kind of banter. This applies not only to 'Banter' banter, but to any and all FA comms channels, be it forums, Discord, or party-approved carrier pigeons.
But what if me and my friend have this in-joke that s/he doesn't find offensive at all, even though it's about Swedes and Australians and sex? Isn't this all a bit Social Justice Warrior?
Remember that anyone can participate in our sessions - new comrades might not understand that you're friends, and may feel uncomfortable enough not to come back - which would be a shame for you, them and everyone who works hard to make the sessions happen. This isn't about politics for us, it's about ensuring that FA is a community where absolutely anyone can come and enjoy some tactical ArmA. Even sex-loving Swedes and Australians.
Ah ... yeah, that makes sense now that you put it that way. So what happens if someone says something that makes me uncomfortable?
Contact any of the hosts and they'll do all they can to resolve the situation. Hopefully without having to use a Party-issued Makarov.

Basically.
Anything else I should know?
I am glad you asked! Step right on through this bunker for the organisational briefing:
FA PlatoonFA Platoon
So, what exactly are all these CO, SL, FTL things I keep hearing about?
The missions (mostly) incorporate the FA2015 Platoon structure. The Platoon, led by a CO, consists of three Squads, led by SLs, each made up of two Fireteams, led by FTLs.
Oh, well, obviously. But let's pretend for a moment that I didn't understand a word of that...
You'll figure it out the minute you see it in action. If you're 100% new to this, my advice would be to grab one of the 'riflemen' slots. You can even ask the host to save you one. It's a perfect position to see how the system works, and it takes no prior knowledge past "listen to your leader" and "point and shoot".
Right. But suppose I still wanna hear the details?
Allrighty then:
Fire and Maneuver?
Exactly. One team suppresses the enemy (so they can't shoot back), and then the other team moves in for the kill.
So, if I'm not an SL or FTL...
You generally don't talk on TS. Unless there's something really, really urgent.
Infantry squad. There are other kinds?
Very observant! There is, indeed, a mechanized squad. Basically, the mech. squad trades one fireteam for an armored transport/fire support vehicle.
Wait, what are 'attachments'?
Attachments are typically 2-man elements (spotter and gunner) that can be used to add a specific type of special weapon to the platoon. For example, the Heavy AntiTank (HAT) team adds, as the name suggests, a heavy AT weapon. An MMG team adds a medium machinegun, which is bigger than what the automatic riflemen have. A mortar team, well, you get the picture.
So, where do they fit on the diagram?
Wherever the CO wants them. When attached to a squad, the Attachment lead (the 'spotter') talks on TS. When attached directly to CO, they speak on Channel commander.
Wait, wait, back up: what's "Channel Commander"?
Oh, right, that thing. Well, CC is a TeamSpeak feature that lets you talk to people outside of your channel. We use it for comms 'one level up' from TS. You can more or less ignore it unless you slot as an element lead. or your lead gets shot and you have to take over.
And if that happens?
I am glad you asked! Proceed right down this hatch for your comms training:
TeamspeakTeamspeak
OK, I got the latest Teamspeak 3 from the website, and have it installed and launched.
Go to "connect" and use these details:
- Address: server.folkarps.com:9988 (note: the domain and port go together)
- Password: freedom
I'm connected. Which channel should I go to?
For the session, you're going to start with "Limbo (Slotting/Dead)". When you've just arrived, hang out there. When the mission starts, everyone will move to the appropriate side channel family (BLUFOR/OPFOR/INDFOR). Further channel split will be handled by the CO. When the mission ends (either for everyone or just for you) return to limbo, and wait for the next mission.
What about Channel Commander?
CC is a TeamSpeak feature that lets you talk to people "over the fence" of your channel. The setup we use is pretty straightforward:
- In TS3 go to Tools > Whisper Lists (Ctrl+Shift+W)
- Click on New (in the bottom-left of the dialog)
- Set a Hotkey (the suggestion is: H)
- Set Whisper to: to Groups
- Set Group Whisper Type: to Channel Commander
- Set Group Whisper Target: to Complete Channel Family
- Click OK
And you're set. To turn CC on/off, either right-click your name in the playerlist and select Channel Commander, or set-up a hotkey (or combination, such as Shift+H):
- TS3 > Settings > Options (Alt+P) > Hotkeys > Add
- In the dialogue that pops-up click on Show Advanced Options
- Under the action Channel Commander select Toggle Channel Commander
- Set a hotkey or hotkey combination (the suggestion is Shift+H)
- Click OK, then click OK again to exit the Options dialogue
Sounds technical
Sounds, yes. But once you see it in action,it gets intuitive. In general, it's highly recommended to have CC if you plan on taking leadership slots. Or, when your superior gets shot, and you get assigned leadership.
That doesn't sound like something that should happen very often, right?
Er...Well, why don't you follow me to the leadership course, just in case?
LeadershipLeadership
So, suppose I get 'promoted' to a leadership position. How do I exactly run my unit(s)?
That's a difficult one, but there are a few best practices:
- Within a fireteam, be ready to step up if your FTL dies! Seniority within the fireteam follows the order of slotting: automatic rifleman #1 is 2IC, then automatic rifleman #2, then the assaultman (AT) ... and then your fireteam pretty much ceases to exist.
- As an FTL, be sure to re-consolidate and reassess your fireteam after each engagement! Remember that your riflemen in the manoeuvre sub-element are carrying spare ammo for your automatic riflemen in the base-of-fire sub-element.
- At the fireteam level, make good use of successive bounding overwatch, as helpfully outlined in TTP3. Within each fireteam, the two colour teams are split very purposefully into distinct base-of-fire sub-elements to fix the enemy with fire and manoeuvre elements to flank or assault the enemy. Be sure to re-consolidate your fireteam after the engagement has concluded.
- At the squad level, make good use of alternating bounding overwatch. Within each squad, both fireteams are very robust and powerful sub-units, capable of acting as either a base-of-fire or manoeuvre element, trading off roles as the squad advances using fire-and-manoeuvre to leapfrog fireteams past one another in quick succession.
- As CO, assign objectives to your SLs, then allow your SLs to use their two fireteams as they see fit in order to accomplish those objectives.
Got it. I think. Wait, is there anything I shouldn't do?
Lots. Here are some to things to watch out for:
- As an FTL, don't treat your colour teams as independent units with sub-leaders. Your fireteam operates as a whole in support of the other fireteam (or vehicle) in your squad, and you are the brains telling the other five what to do. Think of your colour teams as polygamous-battle buddies, not independent units!
- As an SL, don't split your fireteams beyond the range of mutual support. Your squad is the smallest unit with which to accomplish an independent objective such as "Seize the outpost on Hill 138." Use your fireteams to support one another in order to accomplish your squad's objectives!
- As CO, do not give assignments to individual fireteams within a squad. Your SLs will manage their own fireteams; your job is to control the flow of the platoon as a whole and not get bogged down in the specifics of any one engagement.
Well, thanks. That was a fairly comprehensive infodump.
The pleasure is all mine, comrade. The Party is always happy to help. if you have any other questions, feel free to ask in our Discord channel. Now please, after me:
DeploymentDeployment
I really liked the presentation so far, but I don't think I'm quite ready to hop on just yet. I was thinking maybe I'll... wait, why are you handing me a bag of ammo?
You can thank me later, comrade. Your uniform is also inside.

Supply depot, naturally! Where else to we get you your equipment? Oh, and here's your helmet.
Is that a BTR?!?
Of course. And your trusty AK is waiting inside!
...You know what, maybe I 'll come round some other time...
  Now, really, and before I draw my Makarov ... Get. On. The. Troop. Transport.

Girl Develop It is here to provide affordable and accessible programs to learn software through mentorship and hands-on instruction.
Some “rules”
We’ll be using the Terminal (Mac/*nix) or GitBash (Windows) to run queries in this class, but if, after you leave here, you’re hankering for a GUI, head over to Postico (Mac) or, if you downloaded the full package from the Postgres website, you can use the pgAdmin tool that comes with it (all platforms).
There are many other GUIs for Postgres out there, too!
Mac & Linux users: Open Terminal
Windows users: Open Git-Bash
We will not be using Windows "cmd" program, as it uses a different syntax than *NIX systems.
| . | the current directory- e.g.: touch ./muchwow.txt |
| .. | the parent of current directory - e.g.: cd ../BashPartay |
| ~ | the current user’s home directory- e.g.: cd ~/Pictures |
| cd [location] | "change directory" to [location] |
| pwd | "present working directory" - where am I? |
| ls -lah | "list all" of the contents of current directory, including invisible ones, with metadata |
| touch [filename.extension] | create a file called filename.extension in the current directory |
| mkdir [directoryname] | create a directory called directoryname in the current directory |
| clear OR cmd+k | clear the terminal screen |
| help | lists all possible commands |
| man [command] | displays the manual for command |
| which [command] | tells you where the program is installed. if you get nothing back, then the program you’re looking for is not installed or not available on your path. |
| psql | opens a connection to your running Postgres server! |
Working in the terminal, create a directory called gdi_db in the
location of your choosing.
(Desktop? Documents? super-awesome-folder-of-awesomeness?
Somewhere you'll be able to find it again!)
See if you can get to psql
$ which psql
If you see a path, then login like so:
$ psql
psql (9.5.3)
Type "help" for help.
yourusername=#
If successful, you will see the version info and the psql prompt
Open sqlite-shell.
Enter help + ENTER for instructions
We will go through many of these. For now, note that you can use \q + ENTER to exit the prompt
createdb chinook
psql chinook < /full-path-to-/ChinookDatabase1.4_CompleteVersion/Chinook_PostgreSql.sql
.open C:/Downloads/ChinookDatabase1.4_CompleteVersion/Chinook_Sqlite.sqlite
Open the psql program
psql
Then, after the prompt, connect to the chinook database
yourusername# \c chinook
Your prompt should now be the name of the database you’re connected to
chinook#
In a relational database, a table is an organized set of data using columns and rows.
You may sometimes hear a table referred to as a relation.
Let's check out the tables included in the Chinook database:
psql> \dt
List of relations
Schema | Name | Type | Owner
--------+---------------+-------+---------
public | Album | table | yourusername
public | Artist | table | yourusername
public | Customer | table | yourusername
public | Employee | table | yourusername
public | Genre | table | yourusername
public | Invoice | table | yourusername
public | InvoiceLine | table | yourusername
public | MediaType | table | yourusername
public | Playlist | table | yourusername
public | PlaylistTrack | table | yourusername
public | Track | table | yourusername
(11 rows)
chinook=#
We can also check out the schema for the tables.
sqlite> .schema Artist
CREATE TABLE [Artist]
(
[ArtistId] INTEGER NOT NULL,
[Name] NVARCHAR(120),
CONSTRAINT [PK_Artist] PRIMARY KEY ([ArtistId])
);
CREATE UNIQUE INDEX [IPK_Artist] ON [Artist]([ArtistId]);
What are the columns in the Artist table?
Many GUI tools exist for SQLite.
Let's download SQLite Manager, an add-on for Firefox
(First install Firefox, if you do not have it already.)
Spend a few minutes exploring the SQLite Manager
sqlite> SELECT * FROM Album;
1|For Those About To Rock We Salute You|1
2|Balls to the Wall|2
3|Restless and Wild|2
4|Let There Be Rock|1
5|Big Ones|3
This will return all of the results from the table, which could be expensive.
You can have only a subset of rows returned by using the WHERE clause
sqlite> SELECT *
...> FROM Customer
...> WHERE FirstName = "Mark";
14|Mark|Philips|Telus|8210 111 ST NW|Edmonton|AB|Canada|T6G 2C7|+1<PHONE_NUMBER>|+1<PHONE_NUMBER>|mphilips12@shaw.ca|5
55|Mark|Taylor||421 Bourke Street|Sidney|NSW|Australia|2010|+61 (02) 9332<EMAIL_ADDRESS>sqlite>
Alternatively, the SELECT .. WHERE statement can be made on one line:
SELECT * FROM Customer WHERE FirstName = "Mark";
| Operator | Description |
| = | Equal |
| <> | Not equal. Note: In some versions of SQL, this may be written as != |
| > | Greater than |
| < | Less than |
| >= | Greater than or equal |
| <= | Less than or equal |
| BETWEEN | Between an inclusive range |
| LIKE | Search for a pattern |
| IN | To specify multipl possible values for a column |
SELECT * FROM Customer WHERE FirstName <> "Mark";
SELECT * FROM Employee WHERE BirthDate > "1970-01-01";
SELECT * FROM Employee WHERE BirthDate < "1970-01-01";
SELECT * FROM Employee WHERE BirthDate BETWEEN "1965-01-01" AND "1971-01-01";
SELECT * FROM Track WHERE Name LIKE "%Love%";
SELECT * FROM Track WHERE MediaTypeId IN (1,2);

If there was a real-time tag cloud for the RSA conference this year, three words would be in big bold letters: Security (of course), Cloud, and Virtualization. Paul Congdon, from HP's ProCurve Networking group gave us a view into the not-so-distant future where servers, like good house guests, knock before entering. In this case, it's the link they request, and to get it they will properly announce themselves and their intentions to allow the host to prepare to accommodate them.
This capability is a linchpin in removing the process bottleneck in provisioning new services in the data center. For most organizations, the network is manually configured. To keep up with the movement of the provisioning of virtual machines, the network needs to enable "plug and play".
The network is in a unique postion as a "pipe" as well as a "control" where it needs to know what communications go where and plays the role of traffic cop.
This means opening ports between servers, controlling traffic and setting monitors to make sure traffic is optimized. When things change, configuration does as well, especially when a new service is requested. Today, this is controlled by human processes and controls to keep the network up to date with the applications and servers that host them.
In the future, there is the opportunity to move forward in auto-configuration or even smarter handshakes.
In essence, to oversee this process a directory or resources or inventory would exist that allows the network to "know" what is in place within it. This is a new control point for the data center, and is a resource to the network.
802.1.x is technology that has been used in WiFi connections. One reason it was useful in that context is that it's expected that the link drops and reconnects frequently and so is seen as an opportunity for the physical link as well.
The potential upgrades to 802.1 would enable a richer dialog between the server as it starts up its networking process. This would allow the server to announce itself and its requirements (e.g. encryption) and allow the network to respond to these appropriately (e.g. set encryption key). This process can become a big win for configuration management where now, the server can come up in the network and be provisioned according to the policy.
All of this reminds us of the benefits of a company like Apple. Having the unique opportunity to control the model from end to end means have the ability to make better tools. We wonder if natural evolution will get multi-vendor shops a solution for all of their IT assets.
What will it take to get to a model-driven data center?

WHEN THE CAT'S AWAY (Sony Classics) Starring: Garance Clavel, Zinedine Soualem, Renee LeCalm, Olivier Py. Screenplay: Cedric Klapisch. Producers: Aissa Djabri, Farid Lahouassa, Manuel Munz. Director: Cedric Klapisch.  Reviewed by Scott Renshaw.
The Paris of Cedric Klapisch's disarming comedy WHEN THE CAT'S AWAY is no City of Lights. Quaint neighborhoods are vanishing as elderly residents are evicted to make way for upscale cafes and trendy boutiques. Wrecking crews clear away old buildings to make way for the new. Lovers in love have given way to a parade of lonely hearts trying to connect in bars and alleyways. Paris has rarely looked more modern -- or less romantic -- on film.
This is the Paris discovered by a young single woman named Chloe (Garance Clavel) when she is forced by the disappearance of her beloved cat Gris-Gris to get out of her apartment. Gris-Gris, along with Chloe's gay roommate Michel (Olivier Py), is one of the few dependable male figures in her life, giving her plenty of incentive to track him down. Instead of her cat, however, Chloe finds plenty of reminders that she is not alone in her loneliness. Her neighbor Madame Renee (the charming Renee LeCalm) surrounds herself with pets, another neighborhood woman (Gisele Laquit) holds conversations with her dead husband's ashes, and a shy fellow named Djamel (Zinedine Soualem) develops a crush on Chloe while helping her search for Gris-Gris.
Though this all may sound quite depressing, it's actually nothing of the kind. Klapisch finds none of his subjects pathetic; he looks upon them with a subtle bemusement, admiring their ability to persevere and to adapt to the world around them. He has a particularly good time with Chloe, played with an arresting sweetness by Garance Clavel. Some of the film's cleverest scenes, including a seaside vacation rendered in one five-second shot of Chloe swimming alone in the ocean, capture Clavel playing a woman trying to pretend she is resigned to her fate. The film's final optimistic note makes her struggles all the more appealing.
The episodic nature of WHEN THE CAT'S AWAY does grow wearying after a while, with several encounters dissolving before they even register with the viewer. There isn't much narrative momentum to Chloe's adventures -- WHEN THE CAT'S AWAY functions mostly as a walking tour of contemporary Parisian heartache, emphasis on the "walking" -- but there is a genuineness to each one. The many characters in WHEN THE CAT'S AWAY are looking for love in a lot of the wrong places, but at least most of them are still looking. Chloe's quest is really a search for the romantic Paris of song and story, one which may no longer exist, though it may please the heart to believe that it does.
On the Renshaw scale of 0 to 10 cat's meows: 7.

The bad news is, retractions of scientific papers have risen tenfold since 1990. The good news is, the rate has gone from 0.0007% to 0.007%. Going back to bad news, though, some estimates of how many papers ought to be retracted are around 1%, so we still have a long way to go.


OCAMLRUN(1) OCAMLRUN(1) NAME ocamlrun - The Objective Caml bytecode interpreter SYNOPSIS ocamlrun [ options ] filename argument ... DESCRIPTION The ocamlrun(1) command executes bytecode files produced by the linking phase of the ocamlc(1) command. The first non-option argument is taken to be the name of the file con‐ taining the executable bytecode. (That file is searched in the executable path as well as in the current directory.) The remaining arguments are passed to the Objective Caml program, in the string array Sys.argv. Ele‐ ment 0 of this array is the name of the bytecode executable file; ele‐ ments 1 to n are the remaining arguments. In most cases, the bytecode executable files produced by the ocamlc(1) command are self-executable, and manage to launch the ocamlrun(1) command on themselves automatically. OPTIONS The following command-line options are recognized by ocamlrun(1). -b When the program aborts due to an uncaught exception, print a detailed "back trace" of the execution, showing where the excep‐ tion was raised and which function calls were outstanding at this point. The back trace is printed only if the bytecode executable contains debugging information, i.e. was compiled and linked with the -g option to ocamlc(1) set. This option is equivalent to set‐ ting the b flag in the OCAMLRUNPARAM environment variable (see below). -I dir Search the directory dir for dynamically-loaded libraries, in addition to the standard search path. -p Print the names of the primitives known to this version of ocamlrun(1) and exit. -v Direct the memory manager to print verbose messages on standard error. This is equivalent to setting v=63 in the OCAMLRUNPARAM environment variable (see below). -version Print version string and exit. -vnum Print short version number and exit. ENVIRONMENT VARIABLES The following environment variable are also consulted: CAML_LD_LIBRARY_PATH Additional directories to search for dynamically-loaded libraries. OCAMLLIB The directory containing the Objective Caml standard library. (If OCAMLLIB is not set, CAMLLIB will be used instead.) Used to locate the ld.conf configuration file for dynamic loading. If not set, default to the library directory specified when compiling Objec‐ tive Caml. OCAMLRUNPARAM Set the runtime system options and garbage collection parameters. (If OCAMLRUNPARAM is not set, CAMLRUNPARAM will be used instead.) This variable must be a sequence of parameter specifications. A parameter specification is an option letter followed by an = sign, a decimal number (or a hexadecimal number prefixed by 0x), and an optional multiplier. There are nine options, six of which corre‐ spond to the fields of the control record documented in The Objec‐ tive Caml user's manual, chapter "Standard Library", section "Gc". b Trigger the printing of a stack backtrace when an uncaught excep‐ tion aborts the program. This option takes no argument. p Turn on debugging support for ocamlyacc-generated parsers. When this option is on, the pushdown automaton that executes the parsers prints a trace of its actions. This option takes no argu‐ ment. a (allocation_policy) The policy used for allocating in the OCaml heap. Possible values are 0 for the next-fit policy, and 1 for the first-fit policy. Next-fit is somewhat faster, but first-fit is better for avoiding fragmentation and the associated heap compactions. s (minor_heap_size) The size of the minor heap (in words). i (major_heap_increment) The default size increment for the major heap (in words). o (space_overhead) The major GC speed setting. O (max_overhead) The heap compaction trigger setting. l (stack_limit) The limit (in words) of the stack size. h The initial size of the major heap (in words). v (verbose) What GC messages to print to stderr. This is a sum of values selected from the following: 0x001 Start of major GC cycle. 0x002 Minor collection and major GC slice. 0x004 Growing and shrinking of the heap. 0x008 Resizing of stacks and memory manager tables. 0x010 Heap compaction. 0x020 Change of GC parameters. 0x040 Computation of major GC slice size. 0x080 Calling of finalisation functions. 0x100 Startup messages (loading the bytecode executable file, resolving shared libraries). The multiplier is k, M or G, for multiplication by 2^10, 2^20, and 2^30 respectively. For example, on a 32-bit machine under bash, the command export OCAMLRUNPARAM='s=256k,v=1' tells a subsequent ocamlrun to set its initial minor heap size to 1 megabyte and to print a message at the start of each major GC cycle. CAMLRUNPARAM If OCAMLRUNPARAM is not found in the environment, then CAMLRUN‐ PARAM will be used instead. If CAMLRUNPARAM is not found, then the default values will be used. PATH List of directories searched to find the bytecode executable file. SEE ALSO ocamlc(1). The Objective Caml user's manual, chapter "Runtime system". OCAMLRUN(1)

The visualisations were created by Xiao Niu (Shirley) for the Open Data module (COMP 6214) at Southampton University.
Implementation
A number of external libraries, were used to build the visualisations:
- D3.js
- Dc.js
- jQuery
- colorbrewer.js
- crossfilter.js
The books Visualization for the Web and Information Visualization: Perception for Design gave great help for finishing this coursework.


Key highway reopens, Hong Kong remains relatively Calm
Hong Kong: After five straight days of traffic disruption and chaos, Hong Kong witnessed a relatively calm Saturday as a key highway fully reopened after being blocked by protesters the night before.
With the closure of the Tolo Highway and the suspension of the MTR train services on Friday, the government provided free ferry services between Tai Po and Wu Kai Sha, so that residents could travel to other parts of the city, reports the South China Morning Post.
However, main arteries such as the Cross-Harbour Tunnel and stretches of Pok Fu Lam Road and Bonham Road remained blocked, while MTR train services between Fo Tan and Tai Po Market were still suspended. Train services were also suspended between Hung Hom and Mong Kok East after a petrol bomb was thrown onto the track on Saturday morning, but services later resumed.
On Friday night, protesters clashed with police in Mong Kok and occupied the Chinese University (CUHK), before eventually pulling out. Meanwhile, at the Polytechnic University, around 100 protesters were scattered around the campus on Saturday. Some were patrolling the grounds, while others cleaned up trash, or collected and tidied up food supplies in the canteen.
The University of Hong Kong’s main campus, which had become a base for protesters this week, was quiet on Saturday morning, with hubs like the main library closed and few students to be seen. Hong Kong has increasingly has become a battleground between police and protesters since June, when mass peaceful marches targeted a government proposal, since shelved, to allow the city’s criminal suspects to be extradited to mainland China.

1 S.B.Cr.Revision Petition No.264/1993 IN THE HIGH COURT OF JUDICATURE FOR RAJASTHAN AT JODHPUR ORDER S.B.CRIMINAL REVISION PETITION NO.264/1993 Narayandass & Ors. Vs. State of Rajasthan & Anr. Date of Order :: 15/09/2009 PRESENT HON'BLE MR.JUSTICE H.R.PANWAR None present for the petitioners and respondent No.1. Mr.O.P.Singaria, Public Prosecutor for the respondent No.2. BY THE COURT:
By the instant criminal revision petition under Section 397/401 Cr.P.C., the petitioners have challenged the order dated 25.5.1993 passed by Additional Chief Judicial Magistrate (Environment), Pali (for short "the trial court") whereby the trial court framed charges against the petitioners for the offences under Sections 24 read with Section 43 and 26 read with Section 44 of the Water (Prevention and Control of Pollution) Act, 1974.
In view of the decision of a Coordinate Bench of this Court in Natwar Lal Vs. State of Rajasthan & Ors. 2008(1) Cr.L.R. (Raj.) 617, the instant criminal misc. petition is not maintainable directly to this Court, however, it is open for the 2 S.B.Cr.Revision Petition No.264/1993 petitioners, if so aggrieved by the order dated 25.5.1993, to file a revision petition before the concerned Sessions Judge and in that event, the period taken during the instant revision petition will not come in the way for the purpose of limitation.
The criminal revision petition is dismissed.
(H.R.PANWAR), J.

Mr.O.P.Singaria, Public Prosecutor for the respondent No.2.
Since the criminal revision petition itself has been dismissed, the stay petition also stands dismissed.

Abstract: 'Kernel' principal component analysis (PCA) is an elegant nonlinear generalisation of the popular linear data analysis method, where a kernel function implicitly defines a nonlinear transformation into a feature space wherein standard PCA is performed. Unfortunately, the technique is not 'sparse', since the components thus obtained are expressed in terms of kernels associated with every training vector. This paper shows that by approximating the covariance matrix in feature space by a reduced number of example vectors, using a maximum-likelihood approach, we may obtain a highly sparse form of kernel PCA without loss of effectiveness. 1


CC Catalog is a project that gathers information about images from around the internet, and stores the information so that these images can eventually be indexed in CC Search. A portion of the process is directed by Apache Airflow, which is a tool commonly used to organize workflows and data pipelines.
In this blog post, we will explore the way in which we keep information we gather about images up-to-date, using metadata pulled from the Flickr API as an example case study.
Apache Airflow, and the execution_date
concept
Apache Airflow is open source software that loads Directed Acyclic Graphs (DAGs) defined via python files. The DAG is what defines a given workflow. The nodes are pieces of jobs that need to be accomplished, and the directed edges of the graph define dependencies between the various pieces.
A DAG Run is an 'execution' of the overall workflow defined by
the DAG, and is associated with an execution_date
. Contrary to what one might
expect, execution_date
does not mean the date when the workflow is executed,
but rather the date 'perspective' from which the workflow is executed. This
means one can give a command that instructs Airflow to execute the workflow
defined by a DAG as if the date were 2019-01-01, regardless of the actual date.
Our Use of execution_date
Much of the data contained in CC Catalog is pulled from various APIs on the internet, and one strategy we use quite regularly is to make a request of the form:
"please give me all the metadata for photos uploaded to Flickr on 2019-01-01".
Since we're often requesting metadata about user-sourced content on 3rd-party
sites, some sort of date_uploaded
parameter is often available for filtering
results in the API provided by the 3rd-party site. This allows us to partition
large data-sets into more manageable pieces. It also leads naturally to the
strategy of requesting metadata for yesterday's photos, each day:
"please give me all the metadata for photos uploaded to Flickr yesterday".
Doing this each day lets us keep the metadata in our catalog synced with the
upstream source (i.e., the Flickr API). This is where the execution_date
concept comes in. By default, a workflow which is scheduled to run daily uses
the previous day's date as its execution_date
, and so an execution that
happens on the actual date 2020-02-02 will have execution_date
2020-02-01 by
default. This matches up naturally with the strategy above, so we have a number
of workflows that ingest (meta)data into CC Catalog using this default
execution_date
on a daily basis.
Challenge: Data can go stale over time
There are some problems with the strategy outlined above:
- What if a photo changes upstream?
- What if a photo is deleted upstream?
- What about metadata that changes over time (e.g., 'views')?
Given we're only ingesting metadata about photos the day after they're uploaded, we won't be able to capture the relevant data for any of these situations. So, we need to reingest the metadata for images on some schedule over time.
Reingestion Schedule
We would prefer to reingest the metadata for newer images more frequently, and the metadata for older images less frequently. This is because we assume the metadata for newer images will be updated at the source in more interesting ways when the image is newer. For example, assume a picture is viewed 100 times per month.
| month | total views | % increase |
|---|---|---|
| 1 | 100 | infinite |
| 2 | 200 | 100% |
| 3 | 300 | 50% |
| 4 | 400 | 33% |
| 5 | 500 | 25% |
| 6 | 600 | 20% |
| 7 | 700 | 17% |
| 8 | 800 | 14% |
| 9 | 900 | 13% |
| 10 | 1000 | 11% |
| 11 | 1100 | 10% |
| 12 | 1200 | 9% |
As we see, given consistent monthly views, the 'percent increase' of the total views metric drops off as the picture ages (In reality, it appears that in most cases, pictures are mostly viewed when they are new).
Thus, it makes sense to focus more on keeping the information up-to-date for the most recently uploaded images.
Real numbers for Flickr
For Flickr, in the worst case, we can ingest about 100 dates' worth of uploaded image metadata per day. This was calculated using the year 2016 as an example. Because 2016 was around the peak for the number of images uploaded to Flickr per day, the actual number if dates' worth of metadata we can ingest per day is quite a bit higher, perhaps 150.
We'll need to choose around 150 dates for each daily run, and reingest the metadata for all images uploaded on each of those dates. We want to choose those dates preferring newer images (for the reasons outlined above), and choose them so that if we follow the same date-choosing algorithm each daily run, we'll eventually reingest the metadata for all images on some predictable schedule.
Strategy to choose which dates to reingest
Assume we'll reingest metadata from some number n
of dates on each daily run.
We set some maximum number of days D
we're willing to wait between reingestion
of the data for a given image, subject to the constraint that we need to have
n * D > T
, where T
is the total number of dates for which data exists. For
Flickr, there's (at the time of this writing) about 6,000 days for which image
metadata was uploaded. If we set
n = 150
D = 180
then we have n * D = 150 * 180 = 27,000 > 6,000
, as desired. In fact, there
is quite a bit of slack in this calculation. Keep in mind, however, that we add
one date's worth of metadata as each day passes in real time. Thus, we want to
keep some slack here. One option would be to reingest the metadata for each
image every 90 days, rather than every 180. This would still leave some slack,
and we'd have generally fresher data. This means that on each day, we'd ingest
metadata for photos uploaded on that date, as well as metadata for photos
uploaded
- 90, 180, 270, 360, ..., 13320, or 13410 days prior to the current date.
This is better, but 90 days is still quite a long time to wait to reingest
metadata for a recently-uploaded photo. So, it'd be better to use the slack
available to reingest metadata for recently-uploaded photos more often, and back
off smoothly to reingest metadata for the oldest photos only once every 180
days. We ended up using a schedule where we ingest metadata for photos uploaded
on the current execution_date
, as well as metadata for photos uploaded
- 1, 2, ..., 6, or 7 days prior;
- 14, 21, ..., 84, or 91 days prior;
- 106, 121, ..., 376, or 391 days prior;
- 421, 451, ..., 1081, or 1111 days prior;
- 1201, 1291, ..., 3181, or 3271 days prior; and
- 3451, 3631, ..., 10291, or 10471 days prior.
These lists can be generated using the following snippet:
def get_reingestion_day_list_list(*args): return [ [ args[i][0] * (j + 1) + sum(arg[0] * arg[1] for arg in args[:i]) for j in range(args[i][1]) ] for i in range(len(args)) ] get_reingestion_day_list_list( (1, 7), (7, 12), (15, 20), (30, 24), (90, 24), (180, 40) )
This function creates a list of lists of integers based on input pairs describing which prior dates to ingest. An approximate interpretation of the input pairs in this example would be
- Ingest data which is at most a week old daily.
- Ingest data which is between a week and three months old weekly.
- Ingest data which is between three months and a year old biweekly.
- Ingest data which is between one and three years old monthly.
- Ingest data which is between three and nine years old every three months.
- Ingest data which is between nine and twenty-eight years old every six months.
The astute reader will notice that these lists only define 128 dates (including the current date) for which metadata should be reingested. We prefer to be a bit conservative on the total amount we plan to ingest per day, since things can happen that put the ingestion workflow DAG out of service for some time on occasion.
So, using this strategy, we ensure that all metadata is updated at least every 6 months, with a preference towards metadata about images uploaded recently. Because this schedule covers about 28.7 years back in time, this strategy should suffice to reingest all relevant Flickr data for the next 12 years or so (the current date is 2020).
For more context around what we've shown here, please take a look at the CC Catalog repo.
