I recently presented (another) webinar with EMA Design Automation to discuss
DDR5
! This time the discussion was centered around a live post-layout demo. In the example, I showed the analysis of a board with
PowerSI
(which, of course, had some failures when the DDR report was generated). We then used
S-parameter
and
TDR
analysis to track down the failures. Lastly, we used the
Clarity
Via Wizard to generate new ..

Should children be allowed unlimited screen time? If not, what limits should we impose? This is a fairly common question that parents have to reckon with these days. What I find missing in these discussions is that not all screen time is created equal. In my mind, there are two main kinds of screen time. On the one hand, there is the harmful kind. It’s the passive, mind-numbing, and unprofitable waste of time where we allow children ..

Network defenders often struggle to obtain timely, accurate, relevant, predictive, and tailored intelligence about the enemy and other aspects of the operational environment. This document attempts to address that difficulty by detailing a single, curated list of reputable, open sources of threat data, information, and intelligence. This list combines traditional sources such as cybersecurity organizations that publish detailed reports (thi..

These are the questions for set 1 of A Ramble Around CS . Questions for set 1 When you say a = "Hello, world" in your favorite language, how is the string stored? How about "Hello, 世界"? When you say a = "Hello" and b = " world" and then do c = a + b, what happens? How are a, b, and c stored? When you say a = 42, and then b = a, and then b = 17, what are a and b? Why? When you say a = {"foo": 42}, and then b = a, and then b.foo = 17, wha..

I have been playing around with offline non cloud tool replacements for doing things like speech to text and the like. One that I found which looked promising was voice2json which is a command line tool for turning speech intent into text. It can do generic conversion too, but a review of that is not the subject of this post. Following the instructions from the website http://voice2json.org/install.html worked fine up till I tried to ru..

You often need a web interface for your Raspberry Pi projects. Flask is a Python framework that makes it easy to program web APIs. Then you need to add all the deployment steps to automatically run the Flask application. Here I want to show how you can do this with Gunicorn, Nginx and systemd.

It’s no secret that I’m a passionate supporter of software freedom: I’ve written two posts about how Free, Libre, and Open-Source software (FLOSS) is necessary but insufficient to preserve user autonomy: Whatsapp and the domestication of users The phenomenon of a class of predatory busines....

Postgres supports three types for "schemaless" data: JSON (added in 9.2), JSONB (added in 9.4), and HSTORE (added in 8.2 as an extension). Unfortunately, the performance of queries of all three gets substantially slower (2-10×) for values larger than about 2 kiB, due to how Postgres stores long variable-length data ( TOAST ). The same performance cliff applies to any variable-length types, like TEXT and BYTEA . This article contain....

Intro It turns out we have several folks at Square who arrived at programming through boot-camps, or other non-CS paths, and feel a sort of lingering insecurity (or get explicitly told by unkind people) that their path left them without a solid grasp of “the fundamentals”.

For those unfamiliar, Artsy is a fine art marketplace. Knowing that, it follows logically to say that the form via which our partners list artworks for sale is an integral part of Artsy’s core systems. This form, known only as “The Artwork Form,” is whispered about in the halls of Arty’s New York headquarters. It is legendary. It is a colossus. It is old enough not only to predate React v16.8 hooks and context APIs, but Artsy’s use of React....
