I just did some quick tests of hyper-threading on my new E5-2696v3 CPU. I compiled the Linux 6.0.10 kernel with and without hyper-threading enabled. Here’s the times for “make -j36 bzImage” and “make -j36 modules” with HT enabled: real 2m26.540s user 55m25.121s sys 9m56.443s real 10m57.374s user 309m21.531s sys 58m1.070s Here’s the times for “make […] Vox has an insightful interview with the author of “Slouching Towards Utopia: An Economic History of the Twentieth Century” [1]. The main claim of that book is that “The 140 years from 1870 to 2010 of the long twentieth century were, I strongly believe, the most consequential years of all humanity’s centuries”. A claim that […] I just got a E5-2696 v3 CPU for my ML110 Gen9 home workstation, this has a Passmark score of 23326 which is almost 3 times faster than the E5-2620 v4 which rated 9224. Previously it took over 40 minutes real time to compile a 6.10 kernel that was based on the Debian kernel configuration, now […] In response to a post about my latest laptop I had someone ask why I chose an Intel CPU. I’ve been a fan of the Thinkpad series of laptops since the 90s. They have always seemed well constructed (given the constraints of being light etc) and had a good feature set. Also I really like […] The Dell T320 Almost 2 years ago I made a Dell PowerEdge T320 my home server [1]. It was a decent upgrade from the PowerEdge T110 II that I had used previously. One benefit of that system was that I needed more RAM and the PowerEdge T1xx series use unbuffered ECC RAM which is unreasonably […] We are getting towards the freeze for Debian/Bookworm so the current state of packages isn’t going to change much before the release. Bugs will get fixed but missing features will mostly be missing until the next release. Anarcat wrote an excellent blog post about using Wayland with the Sway window manager [1]. It seems pretty […] The Intercept has an amusing and interesting article about senior Facebook employees testifying that they don’t know where Facebook stores all it’s data on users [1]. One lesson all programmers can learn from this is to document all these things in an orderly manner. Cory Doctorow wrote a short informative article about inflation from a […] In May 2014 I bought a Samsung Galaxy Note 10.1 2014 edition tablet (wikipedia page [1]) with 32G of storage. It’s display is 2560×1600 resolution which still compares well to the latest tablets. The Galaxy Tab S8 [2] is the latest high-end tablet series from Samsung and the 11 inch tablet in that series also […] Charles Stross wrote an informative summary of the problems with the UK monarchy [1], conveniently before the queen died. The blog post “To The Next Mass Shooter, A Modest Proposal” is a well written suggestion to potential mass murderers [2]. The New Yorker has an interesting and amusing article about the former CIA employee who […] I’m currently reading the second book of the TriSolar Sci-Fi series by Cixin Liu, I’ve only just started it so this post can’t have spoilers for it and I will also only have minimal spoilers for the first book (nothing more than you will get from pop culture references to it). In the second book […] |
