My first Linux system in 1992 was a 386 with 4MB of RAM and a 120MB hard drive which (for some reason I forgot) only was supported by Linux for about 90MB. My first hard drive was 70MB and could do 500KB/s for contiguous IO, my first Linux hard drive was probably a bit faster, […]

OS security features and server class systems are things that surely belong together. If a program is important enough to buy expensive servers to run it then it’s important enough that you want to have all the OS security features enabled. For such an important program you will also want to have all possible monitoring […] MIT Technology Review has an interesting article about Google Project Zero shutting down a “western” intelligence operation [1]. There’s an Internet trend of people eating rotten meat they call “high meat” (rotten meat) [2]. This is up there with people setting themselves on fire and “nut shot” videos. A young female who was making popular […] I recently bought a couple of PowerEdge T320 servers, so now to learn about setting them up. They are a little newer than the R710 I recently setup (which had iDRAC version 6), they have iDRAC version 7. RAM Speed One system has a E5-2440 CPU with 2*16G DDR3 DIMMs and a Memtest86+ speed of […] It seems that Netflix has an ongoing issue of not working well with IPv6, apparently they have some sort of region checking code that doesn’t correctly identify IPv6 prefixes. To fix this I wrote the following script to make a small zone file with only A records for Netflix and no AAAA records. The $OUT.header […] I’ve recently signed up for Internode NBN while using the Arris CM8200 device supplied by Optus (previously used for a regular phone service). I took the configuration mostly from Dean’s great blog post on the topic [1]. One thing I changed was the /etc/networ/interfaces configuration, I used the following: # VLAN ID 2 for Internode’s […] Hard Drive Brands When people ask for advice about what storage to use they often get answers like “use brand X, it works well for me and brand Y had a heap of returns a few years ago”. I’m not convinced there is any difference between the small number of manufacturers that are still in […] 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 […] |
