Fedora People – Fedora Magazine: Use cpulimit to free up your CPU

Jun 142021
 

The recommended tool for managing system resources on Linux systems is cgroups. While very powerful in terms of what sorts of limits can be tuned (CPU, memory, disk I/O, network, etc.), configuring cgroups is non-trivial. The nice command has been available since 1973. But it only adjusts the scheduling priority among processes that are competing for time on a processor. The nice command will not limit the percentage of CPU cycles that a process can consume per unit of time. The cpulimit command provides the best of both worlds. It limits the percentage of CPU cycles that a process can allocate per unit of time and it is relatively easy to invoke. The cpulimit command…

Planet PostgreSQL – Hans-Juergen Schoenig: Data warehousing: Making use of synchronized seq scans

Jun 142021
 

PostgreSQL contains some hidden gems which have been around for many years and help to silently speed up your queries. They optimize your SQL statements in a clever and totally transparent way. One of those hidden gems is the ability to synchronize sequential scans. Actually, this feature has been around for 15+ years, but has gone mostly unnoticed by many end-users. However, if you are running data warehouses and analytical workloads, you might have already used synchronized seq scans without actually knowing it.
Reducing I/O for large SQL queries
Before we draw any conclusions, it is necessary to understand the problem we’re trying to solve in the first place. Consider the following scenario: 10 users are concurrently running…

TechCrunch – Ring refuses to say how many users had video footage obtained by police

Jun 092021
 

Ring gets a lot of criticism, not just for its massive surveillance network of home video doorbells and its problematic privacy and security practices, but also for giving that doorbell footage to law enforcement. While Ring is making moves towards transparency, the company refuses to disclose how many users had their data given to police.
The video doorbell maker, acquired by Amazon in 2018, has partnerships with at least 1,800 U.S. police departments (and growing) that can request camera footage from Ring doorbells. Prior to a change this week, any police department that Ring partnered with could privately request doorbell camera footage from Ring customers for an active investigation. Ring will now let its police partners publicly request…

– The Conversation – Home – Sick of dangerous city traffic? Remove left turns

Jun 022021
 

Left turns are dangerous and cause a lot of unnecessary traffic. Chris Jongkind/Moment via Getty ImagesTo reduce travel times, fuel consumption and carbon emissions, in 2004, UPS changed delivery routes to minimize the left-hand turns drivers made. Although this seems like a rather modest change, the results are anything but: UPS claims that per year, eliminating left turns – specifically the time drivers sit waiting to cut across traffic – saves 10 million gallons of fuel, 20,000 tons of carbon emissions and allows them to deliver 350,000 additional packages. If it works so well for UPS, should cities seek to eliminate left-hand turns at intersections too? My research suggests the answer is a resounding yes….

PopularResistance.Org – Torture sites and mass graves reported in Colombia

Jun 012021
 

A May 23 report prepared by the human rights organization Justicia y Paz stated that fascistic paramilitary groups, which operate in concert with the far-right and US-backed regime of Colombian President Ivan Duque, have created torture sites and mass graves in an attempt to suppress protests in the city of Cali, which has been the epicenter of continuing countrywide demonstrations.

Planet PostgreSQL – Craig Kerstiens: Better JSON in Postgres with PostgreSQL 14

Jun 012021
 

Postgres has had “JSON” support for nearly 10 years now. I put JSON in quotes because well, 10 years ago when we announced JSON support we kinda cheated. We validated JSON was valid and then put it into a standard text field. Two years later in 2014 with Postgres 9.4 we got more proper JSON support with the JSONB datatype. My colleague @will likes to state that the B stands for better. In Postgres 14, the JSONB support is indeed getting way better. I’ll get into this small but pretty incredible change in Postgres 14 in just a minute, first though it is worth some summary disclaimer on the difference between JSON and JSONB. JSON still exists…

Hackaday – Retrotechtacular: The Drama of Metal Forming

May 302021
 

It may seem overwrought, but The Drama of Metal Forming actually is pretty dramatic.
This film is another classic of mid-century corporate communications that was typically shown in schools, which the sponsor — in this case Shell Oil — seeks to make a point about the inevitable march of progress, and succeeds mainly in showing children and young adults what lay in store for them as they entered a working world that needed strong backs more than anything.
Despite the narrator’s accent, the factories shown appear to be in England, and the work performed therein is a brutal yet beautiful ballet of carefully coordinated moves. The sheer power of the slabbing mills at the start of the film…

Most of this code dates back to 1998, when I built a little 2 player Joust game to push the bounds of what you could do with Div (and at the time Layer) tags in the latest browsers such as IE4 and Netscape 3.

Techdirt. – US Postal Service’s Social Media Surveillance Program Uses Clearview’s Facial Recognition Tech

May 282021
 

Late last month, it was discovered the United States Postal Service was operating a social media surveillance program. The “why” of this was never explained. Apparently, the USPS has time and money to blow, so it has something called an “Internet Covert Operations Program” (iCOP) which it uses to investigate crimes that definitely are not of a postal nature.

According to the two-page bulletin first reported on by Yahoo News, iCOP was trawling social media looking for “threats.” And the “threats” observed in the report shared with the DHS and its many, many (mostly useless) “Fusion Centers” was that the threats weren’t credible.

Great, I guess, but why is the Postal Service surveilling communications that aren’t being sent…

Hackaday – One Inkscape Plugin Collection To Rule Them All

Inkscape is an amazing piece of open source software, a vector graphics application that’s a million times more lightweight than comparable commercial offerings while coming in at the low, low price of free. The software also has plenty of extensions floating around on the Internet, though until now, they haven’t been organised particularly well. The MightyScape project aims to solve that, putting a bunch of Inkscape plugins into one useful release.
The current MightyScape release has a whole bunch of useful stuff inside, for tasks as varied as laser cutting, 3D printing, vinyl cutting, as well as improvements on areas where Inkscape is a bit weak out of the box – like CAD, geometry and patterning. The…

Jacobin – Jeff Bezos Weaponizes the Washington Post Homepage

May 282021
 

The Washington Post’s website — owned, of course, by Amazon founder Jeff Bezos — became a giant native ad Tuesday for Amazon. Bezos is using the paper as his personal megaphone to push back against criticism over wages and working conditions.
Jeff Bezos using native advertising on the homepage of the Amazon website to portray itself as a devoted supporter of a higher federal minimum wage. (Daniel Oberhaus, 2019 / Flickr) A few years after Amazon CEO Jeff Bezos bought the Washington Post, he said it was because it “is the newspaper in the capital city of the most important country in the world” and “has an incredibly important role to play in this…

Planet Mozilla – Manifest v3 update

May 282021
 

Two years ago, Google proposed Manifest v3, a number of foundational changes to the Chrome extension framework. Many of these changes introduce new incompatibilities between Firefox and Chrome. As we previously wrote, we want to maintain a high degree of compatibility to support cross-browser development.  We will introduce Manifest v3 support for Firefox extensions. However, we will diverge from Chrome’s implementation where we think it matters and our values point to a different solution.
For the last few months, we have consulted with extension developers and Firefox’s engineering leadership about our approach to Manifest v3. The following is an overview of our plan to move forward, which is based on those conversations.
High level changes
