LinkMeUp. Issue No. 22. STC Metrotek. Software development for FPGA chips. Instrumentation Ethernet

Stream of the 22nd new year's eve edition of the podcast linkmeup was a blast, and the subsequent publication of 10-th part of SDSM to consolidate the success. There was a full house and the number of listeners and the number of new participants VK groups and the quality of review I wish I could say.

And with good reason — the topic of this issue is Measuring the quality of channels and development of FPGA chips to handle 100 GB/s without loss.
Visiting us employees STC Metrotek: Pavel Kurochkin (Director of development), and Ivan Shevchuk (engineer FPGA).
In the podcast we discuss:
the
    the
  • equipment Line Metrotek — measuring equipment, switches, special design.
    • the
  • methodology for the measurement channels of communication and in particular Ethernet: two-way and one-way delay, jitter, bandwidth, BERT.
    • the
  • measurement Standards: RFC2544 and Y. 1564, OAM, TWAMP/OWAMP.
    • the
  • Chips FPGA. Making use different from ASIC.
    • the
  • to develop a FPGA to process Ethernet traffic at speeds of 100 GB/s. Problems, solutions, schematic diagrams.


In addition, in the 22nd issue, we begin a heading "History of communication". Keep it be Dmitry Bulygin. In the first part of the story about the discovery of electricity and the first prototype of the Telegraph.

Fresh hay from the cow, or 3000 icons submitted!

After the release of the 2000 icons FatCow more than a year . In her fourth year of drawing. the Page called for 560,096 (288,511+235,221+36,364) visitors . To reach 3500 icons, the works will last until February 2013. If you add the size of 64x64, then to mid-2015. While invested $76778 and 2000 hours. Then put 3000 icons , a week before the release on the official website, because the owners of the cows (Bluehost) busy buying crocodile ( HostGator ). / > To understand which icons are the most unique in the world, had to sort 7422 icons. The result did not disappoint... and it turned out that the percentage of unique icons 85,53% cows , 55,90% James and 68,59% from Yusuke. 17.15% — so % unique icons more Fatcow than Fugue . Our designer worked 3.5 hours a day, 5 days per week, for 4 consecutive years. As at the manufactory. Using specially crafted for our set generator Corvo from Berezin Artyom, woven two carpet, put through photoshop and get lep

Knowledge base. Part 2. Freebase: make requests to the Google Knowledge Graph

Изображение
More than a year ago, Google announced that from now on in their search is the mysterious Knowledge Network (an official translation of the Knowledge Graph). Perhaps not everyone knows that a significant part of the data Network available for anyone to use and available via well described APIs. This part is the knowledge base Freebase, supported by Google and enthusiasts. In this article, we first a little nuts, and then try to do a few simple queries in MQL. This article is the second of the knowledge Base. Stay tuned. the the Part 1 — Introduction the Part 2 — Freebase: we make requests to the Google Knowledge Graph the Part 3 — Dbpedia — a kernel of the world of Linked Data the Part 4 — Wikidata — semantic Wikipedia Google Knowledge Graph from the point of view of an ordinary user One of the visible manifestations of the Google Knowledge Graph is the information panel that briefly describes the object that you are looking for.

Group edit the resources (documents) using MIGXDB

Изображение
I wonder the opportunities offered by component MIGX from Bruno17 for MODX Revolution . While he looks clumsy and there are mistakes, but the critical problem. All that is written in this article important for MIGX version 2.5.8-pl (the latter at the moment). / > Many people use MIGX for creating photo galleries , but its functionality is not limited. A real designer to manage data of any database tables. You can even display a list of child resources (documents of MODX) in any container. This will be discussed in this article. Something I learned from documentation MIGDB but, as I understand, it is already rather outdated and much of what is described there simply doesn't work. I will tell you how to make a table with nested resources: 1. Open "Components" -> "MIGX". Go to the tab "MIGX". Click "Add item". 2. On the "Settings" tab to enter a name (Name) of the configuration, for example "ch
