Turning a Twitter thread into a post. I wrote about the performance of AWS’s Graviton2 Arm based systems on InfoQ The last 40 years have been a Red Queen race against Moore’s law, and Intel wasn’t a passenger, they were making it happen. I used to like Pat Gelsinger’s standard reply to ‘when will VMware […]


AnandTech has published Amazon’s Arm-based Graviton2 against AMD and Intel: Comparing Cloud Compute which includes comprehensive benchmarks across Amazon’s general purpose instance types. The cost analysis section describes ‘An x86 Massacre’, as while the pure performance of the Arm chip is generally in the same region as the x86 competitors, its lower price means the price/performance is substantially […]


This is the blog version of a Twitter conversation with my colleague Graham Chastney. Huawei, and the war on trade POTUS #45 has been pursuing a ‘trade war’ with China, as this appears to be popular with his base, even though it makes stuff more expensive for them and will ultimately harm the US economy. […]


The Spectre and Meltdown bugs have been billed as a ‘failure of imagination’, where the hardware designers simply didn’t conceive of the possibility that a performance optimisation might lead to a security vulnerability. I personally find this a little hard to swallow. The very first time I came across side-channel attacks the first thing I though […]


RISC-V[1] is something that I’ve been aware of via the Open Source Hardware Users Group (OSHUG) for a little while, and their most recent meeting was a RISC-V special, with talks on core selection and porting FreeBSD to the platform. Suddenly it seems that RISC-V is all over the news. A sample from the last […]


Update (13 Mar 2014) – this presentation is also available on YouTube I did a presentation at the open source hardware users group (OSHUG) last night. Click to the second slide to get the TL;DR version: With more time I’d like to get some quantitative material on the memory footprint of various cipher suites and […]


One of the things that attracted me to buying a Chromebook was reports I’d read that it would run Ubuntu (and run it fast). Today my 32GB Transcend Class 10 SDHD card arrived, so I set to work installing ChrUbuntu – Ubuntu 12.04 packaged up for the Chromebook[1]. Like some others I hit an issue […]


I got my Chromebook a week ago, so it’s time to reflect on my experiences so far (beyond my initial first impressions). The good parts Blogging – it’s pretty much a perfect blogging tool, and I’ve managed to get a lot of posts done in the past week. The holiday may have had something to […]


Netbook mort?

01Jan13

Over the past few days I’ve seen a few articles about netbooks. One was declaring that 2012 was the year the Netbook Died, another saying the netbook isn’t dead — it’s just resting (with perhaps an even more interesting Hacker News comments thread). So what’s really going on? A couple of years ago I wrote that […]


I’ve been without a laptop for a few weeks[1], and whilst tablets are fine for consumption and the occasional comment I’ve missed having a keyboard for proper creative work. I’ve been tempted by Lenovo’s Black Friday sale for the X230[2], various Ultrabooks and Netbooks[3], but by the time I’d got an SSD[4] I’d be looking at £400-£500. […]
