Oh yeah, that's true. Thanks for correction.

There's one of those* on display in the CS building at the University of Manchester, it's the size of a forearm and IIRC stored 1 byte :) * A CRT RAM thing. It's a refreshing RAM that takes advantage of the persistence of the

Aren't you allowed to have your "click to unsubscribe" button lead to a page with a button that does a POST that actually unsubscribes? I feel like I've seen that approach in use.

Not Centriq but I think there are boards with Cavium ARM chips that you can buy as a consumer (can't find link to cite so may be wrong, but may be a useful avenue for your search).

I suppose this reality is the reason why ops like Cloudflare make a song and dance about it instead of just quietly putting QC chips in their datacentre: they want the market to flourish so that commodity parts become available, software ec

Also when you type into a search field and the thing you want comes up as a succession, you go to click/tap and exactly at that moment, a different suggestion takes its place as the remote site catches up. Twitter is very bad for this.

I worked on Android power perf (frequency scaling in particular) for the last 18 months and I'm not aware of any linkage with the battery state, except for the Battery Saver mode. So yeah same perf, just shorter life. There could be so

So it says the protocol won't be extended initially, only the repo format. I'm trying to figure out the implications of that. IIUC this basically boils down to: can we make sure that when you have a signed tag (i.e. a hash signed

It also looked messed up on mobile - the nav bar took up 20% of the screen. Definitely a point in favour of the motherfuckingwebsite.com school of thought.

One example: applying an effect to an image using custom JS. I also once used this as a fun way to arrange the repeated string "FILE NOT FOUND" in the shape of the characters "404", using the system's native font.

FWIW I find probably 1/3 of my music through DW, 1/3 through manually browsing related stuff on Spotify (if I discover a new artist and see they were featured on a compilation, I might listen to that compilation) and 1/3 from

It's also not just about monolithic Vs microkernel: Linux could decouple filesystem drivers without becoming a unikernel e.g. by specifying a fixed driver API - you could just load FSs as kernel modules. The reason for tight coupling i

In all seriousness, it never occurred to me before that because of access to "globals", an import statement can introduce (or alter the value of!) unexpected names.

In my team we use a tool we developed called TRAPpy [1] to parse the output of ftrace (and systrace) into Pandas DataFrames, which can then be plotted and used for rich analysis of kernel behaviour. We also integrate it into a rather large

FWIW I've also seen bike sharing systems in smaller cities in China (Guilin, Suzhou) that do use docking systems. Could be because those cities are tourist destinations. In Bristol, UK they recently started a bike sharing system that d

This program is discussed amongst a whirlwind of beautiful insight in Douglas Hofstadter's "Gödel, Escher Bach". I doubt I'm in the first 1,000 people to recommend that book on HN but I think it would be remiss to have a

Google have a GPS feed from a good proportion of phones, they don't need to sniff WiFi. Plus they'd have to sprinkle devices for detection throughout the world (I doubt mobile WiFi chipsets do monitor mode)

Dunno about this particular case but I'd say linters are exactly for finding things that are valid but behave differently than the user expects. E.g. "if (x = 1)" is valid C but i'd be pretty unimpressed if a linter didn

I came here to say this but since you've already said it, I'll also provide an on-the-other-hand! On the other hand, CPU utilisation is used to scale CPU frequency on some systems. This generally works OK but if a workload is spen

by bjackman 9y ago
Power consumption is more complex than processor load - you have to think about how P-state (cpufreq) and C-state (cpuidle) selection is affected by the workload and now the scheduler distributes load across cores.

Cool, thanks for the info. It's such a shame we have to resort to (slightly) compromising on security & reliability to make banking work for consumers. Do you think there's a future where there's a standard API that banks

Have you integrated this directly with the banks or do you take user's login details and scrape the online banking sites (like MoneyDashboard does)? I would be more than willing to switch banks just to get a read-only API for this kind

Aside from your edit: I have heard (but cannot back up) that there are sometimes things you can buy in person in Shenzhen but not on Taobao. It's hard to believe though.

You might be surprised how many Android apps work on x86 too. Either they are "fat" (have libraries for multiple ABIs in the .apk) or the Play Store has multiple versions, and delivers you the one for your platform. Edit: however,

IIUC installing the snap should be easily reversible, but it only installs an installer :). The installer then does some much more intrusive stuff, It has to install kernel modules for ashmem and binder. Can't really blame the devs, it
