The Harvard PASS system (https://syrah.eecs.harvard.edu/pass) intercepts system calls to generate provenance information. When an event occurs, the corresponding system call is triggered. This dataset distinguishes the same processes by version, ensuring that no loops occur. In addition to dependency properties (such as INPUT, GENERATEDBY, FORKPARENT, RECV, and SEND) between objects, the object's own properties (such as NAME, ENV, ARGV, PID, EXECTIME, and TYPE) are also collected.
There are mainly three types of objects collected: file object, process object and network connection object. For file object, its attributes include specific information about the file itself, such as file name, file storage space, storage location, and file node number. For process object, its attributes mainly contain the process name, the PID number of the process, environment variables, the process creation time, etc. For network connection object, it is used to record the transmission of data on the network. Network connection objects can be considered as file objects, the attributes of which include the source port, the destination port, the source IP address, and the destination IP address. There are mainly three types of dependencies collected: (1) FORKPARENT: Process to Process, if a process P creates process Q, the provenance record "Q FORKPARENT P" is generated, we represent it as, Q->P. (2) INPUT: Process to File, if a process P reads the contents of a file A, the provenance record "P INPUT A" is generated, we represent it as, P->A. (3) GENERATEDBY: Network connection object to Process, if a process P sends data from the network connection object B, the provenance record "B GENERATEDBY P" is generated, we represent it as, B->P.

--- layout: post title: Using Statement with an “expression” date: 2010-05-24 20:08:28.000000000 +02:00 categories: [] tags: - C# - Using Statement status: publish type: post published: true meta: {} author: login: admin email<EMAIL_ADDRESS>display_name: Philippe first_name: Philippe last_name: Vlérick excerpt: !ruby/object:Hpricot::Doc options: {} ---
Reading More Effective C# book, I was amazed to find out that the using statement can be used simply with an expression:
using-statement:
using ( resource-acquisition ) embedded-statementresource-acquisition:
local-variable-declaration
expression
If the resource-acquisition is an expression, the variable resulting from the expression will be inaccessible to the embedded-statement.
Now, the reason why this is outlined in Bill Wagner’s book is when you write generic classes. Simply put, if expression is something like “a as IDisposable”, if a actually implements IDisposable, it will be disposed after the using statement. If it does not implements IDisposable, nothing will happen.
The beauty of this is that you don’t have to know, it will work in all cases.
I didn’t know that, and I find it very neat!

Scaling Reporting at Reddit (redditblog.com) |
| Reddit’s Advertising business has seen incredible growth over the last few years and has consistently evolved to meet the needs of our increasing advertiser base. Providing transparency to advertisers on how users engage with their ads is a critical feature for any advertising platform. To derive the information that advertisers care about, we need to empower them to perform specific aggregates and breakdowns across large amounts of data. Our ads generate tens of gigabytes of event data per hour. Allowing advertisers to query across the last six months of data means that we have hundreds of billions of raw events to sift through. We also need to scale well beyond this since we expect our event volume to significantly increase over the next year.... Read more |

Biotica is a work in progress project. It's a serious game + an hybrid game using augmented reality, about biodiversity in cities.
We wanted to create a game to raise awareness among people about the interaction between the fauna & flora in cities.
Players needs to cooperate to instaure a beautiful & useful nature in their cities. The board is modular, and players can choose the tiles they want so each game is different
They will learn a lot about the biodiversity while having (i hope) fun during the game.
Learn more : An article about Biotica 🇫🇷
Currently, we created a POC, with a board game, cards, pieces and an Unity app using Vuforia + a prototype made on Adobe XD for the experience.
The 'future' application has the role of game master & opponent.
We meet a lot of professionals, to gather the right informations about the flora. We made some users play test with an early version of our prototype, during a
board game festival.
The game will go through many changes and maybe, it won't be the same in the future.
