Wifi usually just works. In the past I haven’t had to worry much about performance as for home use things have always been bearable and at work it’s never been my job so I just file a bug report with the relevant people when things go wrong. But a few years ago I had some […]

This page has summaries of some USB limits [1]. USB 2.0 has the longest cable segment limit of 5M (1.x, 3.x, and USB-C are all shorter), so USB 2.0 is what you want for long runs. The USB limit for daisy chained devices is 7 (including host and device), so that means a maximum of […] I’ve just bought a HP ML110 Gen9 as a personal workstation, here are my notes about it and documentation on running Debian on it. Why a Server? I bought this is because the ML350p Gen8 turned out to be too noisy for my taste [1]. I’ve just been editing my page about Memtest86+ RAM speeds […] I just started looking at the Kubernetes documentation and interactive tutorial [1], which incidentally is really good. Everyone who is developing a complex system should look at this to get some ideas for online training. Here are some notes on setting it up on Debian. Add Kubernetes Apt Repository deb https://apt.kubernetes.io/ kubernetes-xenial main First add […] C Thi Nguyen wrote an interesting article about the difficulty of escaping from Echo Chambers and also mentions Epistemic Bubbles [1]. An Echo Chamber is a group of people who reinforce the same ideas and who often preemptively strike against opposing ideas (for example the right wing denigrating “mainstream media” to prevent their followers from […] This is another post about EVM/IMA which has it’s main purpose providing useful web search results for problems. However if reading it on a planet feed inspires someone to play with EVM/IMA then that’s good too, it’s interesting technology. When using EVM/IMA in the Linux kernel if dmesg has errors like “op=appraise_data cause=missing-HMAC” the “missing-HMAC” […] I decided to start work on repeating the tests for my 2006 OSDC paper on Benchmarking Mail Relays [1] and discover how the last 15 years of hardware developments have changed things. There have been software changes in that time too, but nothing that compares with going from single core 32bit systems with less than […] Dr Justin Lehmiller’s blog post comparing his official (academic style) and real biographies is interesting [1]. Also the rest of his blog is interesting too, he works at the Kinsey Institute so you know he’s good. Media Matters has an interesting article on the spread of vaccine misinformation on Instagram [2]. John Goerzen wrote a […] I previously wrote about getting a Brother MFC-9120CN multifunction printer/scanner to print on Linux [1]. I had also got it scanning which I didn’t blog about. found USB scanner (vendor=0x04f9, product=0x021d) at libusb:003:002 I recently upgraded that Linux system to Debian/Testing (which will soon be released as Debian/Bullseye) and scanning broke. The command sane-find-scanner would […] I’m playing with a HP Proliant ML350P Gen8 server (part num 646676-011). For HP servers “ML” means tower (see the ProLiant Wikipedia page for more details [1]). For HP servers the “generation” indicates how old the server is, Gen8 was announced in 2012 and Gen10 seems to be the current generation. Debian Packages from HP […] |
