IIRC IceCast essentially extends/abuses HTTP/1.1 chunked encoding to frame such metadata. The original Nullsoft's ShoutCast protocol simply multiplexes fixed size blocks of mp3 data with length prefixed metadata packets. In b

That is because MP3 is not a file format in the first place. The file is originally simply an stream of MP3 frames written into a file without any structure and usually with technically invalid and undecodable frame at both ends (due to how

Many years ago I wrote https://github.com/adh/random-tools/blob/master/byc.c which tends to be the tool that I use for copying images from/to block device (it was originally meant for something else

Both dd's name and its command line syntax is intentionally arcane and bizarre and originally meant as a joke ;) The tool is originally meant to do various conversions of formats of data on 8-track tapes and both its name and syntax is

In fact SSCC is simply and unique identifier for particular logistics unit (ie. the one indivisible thing that you send from point A to point B) and does not in any way describe some kind of class of things sharing the same geometry. In the

I think that that dichotomy is obviously wrong. More useful dichotomy between animals and "not-animals" involves capability of locomotion, which is something that althought not strictly correct can at least be observed from outsid

It is somewhat natural to just refer to 802.X standards as 802.X when implementing them as that is the correct name of the standard and you need to read most of it in order to implement it. If you want to talk about distinct added features

While receiving analog radio is trivial for the processing required, it is fairly low frequency transmission which requires antenna sizes which are not entirely practical for phone-like device. I would even assume that many phones contain t

I second the suggestion that every software engineer should at least be able to imagine how they would go about building computer from discrete logic. When commercial computers were built from discrete logic in this manner, there was distin

That is pretty much an inverse problem ;) If you care about that you probably should use mosh as that does solve that by design and not by random chance. On the other hand using VPN with fixed tunneled endpoint IPs causes idle TCP connectio

Some NAT implementations ignore TCP keepalives. Alcatel branded ADSL modem/router I had used in 2005-ish certainly did and IIRC some more recent Zyxel ones do the same.

The first two points have to do with the fact that if you do the whole process only with symmetric primitives you are only spliting the traditional salted hash into two computations one of which then becomes essentially redundant. If client

by dfox 6y ago
Because calculating the salted hash on the client side will just substitute the hash for password and render the whole hashing useless. Also it would require additional roundtrip to server in order to get the stored salt. Then there is the

That kind of construction involves storing whatever is required for login in plaintext on the backend side. You can get around that limitation by using something like SRP, but that is even more complex than using RSA. On the other hand SRP-

Scheduling fixed pauses between runs is often better (for jobs where fixed frequency is not critical, which is most of backround jobs) because you then don't have to care whether it will complete within the period. It is certainly simp

That is mostly an issue with Windows' device driver architecture and not with USB itself. Windows tries hard to assign unique and persistent internal "name" to every device it has even seen, the resulting device record then h

All Unix-like systems had exactly the same issues with large file support on 32b architectures. The solution was standardized in 1996 and adopted by most relevant OSes relatively quickly. Another issue is that support for large files has to

Pixomatic wasn't just on par with UE1's SW rasterizer it was somewhat explicitly designed to be the SW rasterizer for UE2. The thing was notable by the fact that it had feature parity with HW Direct3D implementations of the time a

The card-side implementation of NFC payments is surprisingly resource hungry for parasitic powered NFC chip, but utterly negligible for a device with own battery, 64MHz ARM core and 4MB of storage. On the other hand good luck with getting s

The issue there is interaction between exceptions and deterministic destructors. In the end it means that there has to be some hidden code for every stack allocated object whose destruction could be skipped over by exception handling mechan

Windows CE is modular and in fact most of what one would consider "Windows CE GUI" was IIRC separately licensed and fairly expensive module.

Windows CE as an OS has lot of peculiarities. For essentially single-tasking game console most of them are probably irrelevant, but on the other hand these peculiarities would probably make straight port of typical DirectX game from desktop

It is other way around: in the original class-ful internet the numerical range of first octet directly implied what is in CIDR called netmask length. The original IPv4 implementations probably did not even have concept of netmask and this w

For a long time that was my approach to LoB backoffice applications: make the backend clever enough that there is no need for non-trivial user interfaces (in the sense of being non-trivial to implement). That in part works well but on the o
