recent chrome versions actually throttle these reports down to 60hz max, checked this on several systems and mice

You actually should not, usual (non-gaming) mice still do the same (most touchpads in cheap laptops even slower, they share already slow i2c bus with several other endpoints), and the article ignores drivers and the UI stack altogether.

I could not find anything about google or other browser vendors in the article. My take is that you should trust provider (developer, hoster) of said encryption app to send you actual implementation, not something that looks like the real d

I would not call 2nd video "skillful", that SOIC was molested, not soldered :(

I'm scratching my own itch: building a yet another audio signal generator for smartphone. I need some extra functionality that is not available elsewhere, and impose some limitations "just because": it must be bare minimal PW

I'd recommend a spoon-style tip* instead of using a fresh drop of solder each time. [*] like these https://www.jbctools.com/cartridges-category-4-design-Spoon-...

Thanks! That cisco sounds like a hell of equipment. Is it loud? And how much power does it draw? And thanks for pointing at CWDM4, these are quite cheap on ebay now

This pic is quite unsettling, I didn't understand why at first, but this blue wire pinched under the bolt...

Yep, these cards need a fan (or any kind of directed air flow). Where did you get "several ms of latency" figure from? I have not measured external card, but may be I should do it... Because cards themselves have latency in range

Nice! Cool to hear from a fellow admirer of overkill-lan setups ;) Which cards do you prefer for 100G, and what is the situation with dacs/optics?

Officially: to access NAS, get raw market-data files (tens to hundreds of gigabytes a day), not needed on laptop every day, but only once in a while to fix or analyze something. Really: because I can, and it is fun. I upgraded my home lan t

Ha! Been running these for years on both linux and windows (on lenovo x1 laptops). Using cheap chinese thunderbolt-to-nvme adapters + nvme-to-pcie boards + mellanox cx4 cards (recently got one cx5 and a solarflare x2). Pic of a previous cx3

I have read both articles (this and zig-cool), and I regret the time wasted. IMO, both articles fail to deliver on their titles :( Both fail to list really cool parts, and both reiterate same arguments several times. This one even looks lik

It's not mobile, it is IE6 era all over again, when sites are designed and work only in one (dominant) browser :(

Yup, exactly how I use zig most of the time: just use good old OS apis, it is very easy to use cImports, when I'm too lazy to create zig definitions )

Yes it is. In hft (or any algo trading nowadays) it is commonplace to use usermode networking since like ~2010 or even earlier. The part of NICs address space is mapped to a process (control registers and memory rings), and whole driver jus

Source repository ( https://github.com/ieviev/resharp ) seems to be deleted. Does anyone have a link to the actual code? Edit: answering myself, this seems to be (at least partially) merged into the dotnet itself https:

I suppose this is about different thing: male/female are about two parts of connector mating together. And each of these parts has mating side (to the other) and side where wires come in. This is the first time I see this distinction t

All internal parts are usually measured by low-overhead logger (which materializes log messages in a separate thread, and uses rdtsc in the hot path to record timestamps)

by omgtehlion 1y ago
In HFT context (as in the article) measurement is quite easy: you tap incoming and outgoing network fibers and measure this time. Also you can do this in production, as this kind of measurement does not impact latency at all

About doorbells (and charging them): there exist battery-less wireless doorbells, they generate enough energy from pushing the button. I got some off aliexpress several years ago.
