Knowing that we have to create a Babylon project after the Earth-Minbari war anyway, Irak took a lead and decided to use the Babylon name so that nobody would dare to attack us in the first place.
Setting aside the issues from waste during the manufacturing process and the messes that have been made (see 3M plants for example), is the actual Gore-tex product itself hazardous? Like, how much of the material do you have to eat, and how edible is the Gore-tex product? I get Teflon coatings scratching and getting mixed with the prepared food, but I typically don't go around gnawing on my clothing. Does Gore-tex leach anything that can absorbed by the skin while wearing it?
in the 80s on every ski trip, my parents would spray me down with scotch guard while i stood there in my cold gear. think of the scene from A Christmas Story with Randy in his overstuffed coat, but then imagine the mom spraying him down with a can of scotch guard. that was me.
does that count as being overused, or just as intended?
The title says this is expanded PTFE, which seems like it wouldn't need an additional PFOTS coating. I doubt it would shed similar small molecules to a PFOTS coating as it's a different material (polymerized tetrafluoroethylene).
I also doubt you would get similar endocrine disruption with PTFE polymerization biproducts since you won't have the "polar head/fluorinated tail" structure that PFOTS has.
Not exactly. Its properties come from PTFE, which is not water soluble. PFOS is a surfactant, like soap. You can’t make a jacket out of it — it’s water soluble.
PFOS was used in the manufacturing process. It’s quite problematic, but it’s actually the end product.
Is it more precisely: don't use PFOA or PFOS anymore, switching to less-proven-guilty chemicals with different lengths?
Either way, my concerns are mostly: how much fluorinated waste they release from factories and what happens at the end of product lifetime. Solid fluorinated compounds don't seem atrocious, as they can be reduced to safe minerals if burned properly unlike the spray-on compounds and factory leakage.
You may have to turn on your VPN to appear to be coming from an EU country (or maybe even from inside Germany, since this Youtube channel, Strg-F [literally "Ctrl F", so 'find'] is part of `Funk`, which is a German public broadcast station) but I found this half-hour-long documentary on PFAS and PFOAs, more generally, to be quite informative:
The video covers Chemours, DuPont, etc. and how there's a town in the US where the rain and soil is poisonous due to PFOA production in the past (and still on-going: not PFAS but other deemed-safe-by-corporate-lawyers PFOAs). The man who they interviewed had pet dogs that he would let outside and the husky loved being outside in the rain. However, the dog developed sores / lesions on its back and then died. Turns out the groundwater and basically the whole environment around the PFOA factory is highly toxic.
The video also interviewed a worker at a PFOA plant in Germany who has (had?) thyroid cancer, I believe it was, and suffers from many disrupted endocrine system effects. (He worked inside a PFOA factory where sometimes the chemical vapor would condense on the ceiling and drip down on to the workers. Again, the ground water and soil there is not safe for human or animal consumption.)
They also cover / touch upon the lawsuits that farmers with grazing cattle (that died off) tried to bring against PFOA manufacturers like DuPont, Chemours, etc. Unfortunately, most of those farmers are now dead due to cancers of various sorts (from consuming PFOA-laden groundwater, the same water which they were giving to their animals which died by the hundreds a few decades ago).
They also touch upon how difficult it is to recycle PFOA-containing fabrics: they must be incinerated at much higher temperatures to render the compounds inert and safe for disposal in the way that regular trash is disposed of after incineration.
So your only valid solution is to use __getattr__, which is guaranteed to work. But either you load all missing value on first access, and you can only lazy load once, or you pay the price of a method call for attribute access every single time. And in all cases, you won't have type hint doing the ork for you.
An hybrid strategy would be to always use __dict__ pointing to an empty dict you lazy load later, and @property for attribute that are only for the local object. Then you will pay the price of the of the method calls only for non lazy attributes.
Depending of your work load and data shape, one solution will be much better than the other, but nothing as elegant as the ChainMap.
The question is more complicated than that: curl is so popular it is used on systems where c99 is not available. The question is how many of those exist, and are at which point it's not worth supporting them anymore.
Don't you have to compile separately for each `msvcrt` environment, as I thought they aren't binary compatible? And would a non-C99 msvcrt necessarily have an `snprintf()` implementation in its libc-equivalent dll?
You can call code compiled with one msvcrXX from code compiled with a different msvcrXX, provided that you don't try passing things from one to the other (that is, no passing a pointer to a FILE structure, or even a file descriptor since the file descriptor table is on the msvcrXX instead of the kernel), and always free or realocate memory using the same msvcrXX (that is, don't allocate memory and expect your caller to call free() on it, always provide a custom deallocation function for your objects).
This is possible because, unlike on Linux where function names are global, on Windows function names are scoped to the DLL, so you can have MSVCR71.DLL and MSVCR81.DLL loaded at the same time in the same process and they won't interfere with each other.
OK, but isn't the point of building a program that links to (say) MSVCR71.DLL that you're expecting to run it in an environment where (say) MSVCR81.DLL isn't available?
I don't see how that fixes the problem of possibly not having an snprintf() implementation on a system that doesn't have a C99-compatible MSVC runtime environment.
Did I miss an implication of your comment somehow?
If you compile your program against some MSVCRT then it's your job to make sure that MSVCRT is available on the machine where your program is installed, by delegating to its installer.
All supported MSVCRTs are installable on all supported Windows SKUs.
Yes, that's the thing I always forget, the way Windows deals with multiple incompatible versions of msvcrt is that every application ships its own copy of libc, and hopefully the installer is well-written enough to only copy it into place if it's newer than the newest release of the same major version that's already there, lest a random app re-introduces a bunch of security issues that should have been closed by the last security update for every other application that uses the same msvcrt.
...and by "forget", I mean "block out due to trauma, because surely it can't be that stupid".
Linker scripts change whether or not symbols are added to a global symbol table for subsequent requests (i.e. "exported"). Though, you don't even need a linker script to effect visibility as both GCC and clang provide a visibility function attribute, and you can change the default visibility through a simple compiler command switch.
dlopen permits you to control whether exported (externally visible) functions in a module become available to satisfy link dependencies in the application, such as subsequent module loads. See the dlopen flags RTLD_GLOBAL and RTLD_LOCAL.
dlmopen is for controlling the visibility of shared library dependencies pulled in by dlopen'd modules, whether RTLD_GLOBAL or RTLD_LOCAL, which only effect the immediate symbols in the module and not symbols from automatically loaded shared library dependencies. If you link the main application with OpenSSL (-lssl -lcrypto), or a prior module you dlopen'd pulled in OpenSSL as a dependency, then those OpenSSL symbols become available to satisfy requirements for subsequent dlopen'd modules. dlmopen allows you to create an entirely different symbol namespace for a module or modules, where symbols dependencies are only ever satisfied from that namespace, and exported (global) symbols, whether pulled in by dlopen or transitively via a shared library, are never visible outside that namespace.
None of these options directly map to the behavior of DLLs. DLLs fundamentally use different semantics, AFAIU. The closest behavior to DLLs might be DT_RUNPATH + dlmopen, but dlmopen use is explicit so not really the same thing. You could use ELF symbol versioning (maybe in combination with DT_SONAME and DT_RUNPATH) to accomplish the same thing as DLLs by effectively renaming all the symbols in a library (e.g. attaching a version component), but there aren't any tools around to help automate that, AFAIK; you'd have to generate linker scripts and it'd be a complex build. Much easier to just static link at that point.
For C, Windows has had a stable CRT (libc in Unix speak) for several years now, since Win10. There are still cross-runtime compatibility concerns with C++, but those shouldn't apply here.
More than you would think, but curl is used to talk to the local network too, or inside VPN as well.
Some hacks are quite crazy.
E.G: there is this very old navy broacasting protocol, NMEA (https://en.wikipedia.org/wiki/NMEA_0183), that was designed so it could be transmitted through old fashion radio waves. You'll find it in some sonars, water sensors or AIS beacons. For this reason, despite that it looks more like a layer 4 protocol, it embeds its own packet format and checksum, all in ASCII, that clients are expected to parse.
Now of course, a lot of devices are still emitting their data in NMEA, and it's not uncommon to be able to just telnet or netcat (if UDP) into one to see the data flowing.
But after a while, people started to aggregate those data from their numerous sources into one single router, and expose this router for convenience through... HTTP over TCP/IP.
And now you have those all those old computer towers (some still rocking a CRT screens or windows xp) doing long polling to get broadcasting data over a protocol that was made for request/reponse, to read the payload that is another protocol that was meant for radio equipment and hence requires manual consistency checks, that is transported by yet another protocol that is doing its best to preserve packets.
And they say the spirit of hacking is dead :)
(sometimes I feel IoT or domotic stacks look the same honestly)
Of course, somewhere in there, there is a curl call. The question is therefore does curl author want to support a potential upgrade path for such twisted use case or not. I would say "nahhhh", but maybe curl had precisely the success it did because the author was ready to support it in crazy settings.
Maybe. Or maybe they have the only know toolchain to work installed on this single machine somewhere in the basement (seen in a healthcare corp), or they have a chain of trust that needs way too much effort to verify again (seen in the army), or they are not comptent enough to do such thing (seen in airports), or their whole stack is so old it can only run on this stuff (seen in ports), or their target is exotic and you can't cross compile to it easily (seen in aerospace).
Again, not sure that it means curl should endorse such niche situations, but the modes of failure are numerous.
Maybe on desktop, but on mobile I don't think the benefit would be that clear cut, because mobile are slow, and heavy computations drain battery pretty fast.
This work if you have only experienced professional developpers in the team. If you have juniors or non devs (mathematicians, geographers, qwants...) that just happen to also code, rebase is a minefield. This is espacially true in open source contributions.
Merge and conflict resolution is a minefield if unexperienced developers do it too. Fortunately it can (often) be arranged that those with some understanding of the issues involved can do the resolution.
> SQL is a little language for describing database operations
Yeah, SQL is not a little language anymore.
It started as one, but because a lot has been added to it and SQL flavors for Oracle or Postgres are anything but tiny. Windowing, nesting, json handling...
I think the author is kinda proving with this that a successful little language does not stay little, and hence little languages are not the future.
And don't get me started on DSL in general. Just lookup my username and "DSL" on hackernews for endless rambling.
Maybe the term modular would be more appropriate than little? Every solution that has gained widespread dominance, take the shipping container, has been thanks to its flexibility, and modularity.
