Almost impossible, it depends on how fast they're being generated and the precision of the timestamp. The real problem is two years later when someone finds and removes that usleep(10000); /* sleep 10 µs */ that was the hard speed brake needed for the UUID generator, and suddenly duplicate IDs start showing up a few times per day or something similar.

I keep telling the dev teams I'm on that with enough data points, all those random numbers will (probably) eventually collide, and *then* we'll see how robust their software really is. At least your database flagged it, and hopefully nothing major exploded.

And yet, plenty of experienced devs, including team leads and CIOs, are convinced it's impossible. As in, they absolutely don't write code to deal with the condition. So a bad RNG can randomly destroy the system far sooner than expected at any time, and it won't be noticed, caught, re-genned, or anything, with concurrent corruption being entirely possible. They're fine with it. I feel like these are the same guys who don't check to see if malloc() succeeds.

I like to ask them, "If it's impossible, you're using too many bits, right?". I haven't talked any of them into hedging with a brownian motion detector, or a lava lamp or something for better randomness yet, but I'm still trying.

I really hate it when the recommended install method is curl-ing some script directly into a shell, often as root. Especially since it's pretty well known that the remote end can tell whether it's going to a script or a file.

Quarkdown's page has this:

curl -fsSL https://raw.githubusercontent.com/quarkdown-labs/get-quarkdo... | sudo env "PATH=$PATH" bash

And… yuck. And that ".sh" is kind of annoying all by itself.

GoDaddy proved themselves corrupt forever ago, grabbing domains their customers didn't pay for in time and then auctioning them back to those customers for massive markups. There's a litany of terrible things they've done.

My main domain is still with nic.ddn.mil / rs.internic.net … i.e the travesty of itself today, networksolutions, which once had the ethics to only give one domain name to each physical site so as to make sure future generations could have them. That fled the moment some pharm company attempted to buy about 90 domains at one and the greed set in. But the same process they failed to improved for a decade or two after getting an income stream is still considered more reliable that GoDaddy.

GoDaddy is corrupt, the joke everyone already knew who was in the know.

This is happening in Colorado too, meaning it could be part of a national push:

Colorado Senate Bill "26-051"

The actual bill and links to its two sponsors Matt Ball and Amy Paschal.

    https://leg.colorado.gov/bills/SB26-051

    https://leg.colorado.gov/legislators/matt-ball

    https://leg.colorado.gov/legislators/amy-paschal

It puts the infrastructure in place to do all of those things if a future(?), authoritarian regime wants to.

* It also reveals that visitors to any site are children, compromising their privacy and opening them up to targeted advertising

* The data will undoubtedly be added to the accumulated, traded databases so many services use

* The bill makes onerous demands of developers to consider other items that may suggest the user is actually in a different age bracket, like doing websearches for "toys" (child) or "toys" (adult) - which works what percentage of the time, exactly?

* And it's totally ineffective, since kids can look at porn anywhere they want, or internationally, regards of useless bill like this

The most egregious part of this bill is that:

* It legislates that if kids connect to a website, that website can query their age brackets (an "age signal"). This means their approximate age is revealed for kids-specific advertising, manipulation, or even sold to a pedophile group.

A DEVELOPER SHALL REQUEST AN AGE SIGNAL WITH RESPECT TO A PARTICULAR USER FROM AN OPERATING SYSTEM PROVIDER OR A COVERED APPLICATION STORE WHEN THE DEVELOPER'S APPLICATION IS DOWNLOADED AND LAUNCHED.

Basically SB 26-051 creates a mechanism that can be used to harvest the data that certain users are kids and then sell that data to anyone who will pay for it.

Data like this is traded internationally, which makes it tragic that elected lawmakers would waste time pushing a bill whose only mid-term effect would be making Colorado less attractive to developers and software companies.

The irony is that normally your kids would have been protected, by standard practices, from having their age exposed. This bill reverses that, putting your children at more risk.

The bill also would force many devices to provide age bracket data that are surprising to most people, because this part:

"DEVICE" MEANS ANY GENERAL-PURPOSE COMPUTING DEVICE THAT CAN ACCESS A COVERED APPLICATION STORE OR DOWNLOAD AN APPLICATION.

... means anything with Internet access and storage. This includes smart televisions, thermostats, tablets, smartphones, smart watches, some fitness tracking devices, some smart toilets, and so on, all potentially reporting your activity on demand, even if that back-end service has nothing to do with porn.

The bill is also poorly structured. Clearly it's intended to focus on services like app stores (Android, Apple), but by attempting to integrate support for this into operating systems, makes it available to hostile actors for any purpose worldwide. Further, it requires developers to guess whether other available information on a user might mean they're really in a different age bracket, exposing them to fines of $2500 to $7500 per minor "affected" (note: "affected" is not defined in the bill). The exemptions give blanket protection to developers working on for-internal-use software, but give no exemptions to recreational programmers. non-profit personal software, university projects, and so on, casting a chilling effect across software engineering generally.

Lastly, the bill is ineffective. Most of the web runs on Linux, a coöperative international effort, nominally controlled by one man in Finland. There is no chance of this bill's mechanism being implemented in this context. Nor will other developers be especially interested in rewriting software for this Colorado-specific bill. Further, the kids supposedly being protected from all the Colorado native porn sites would just web-browse to nearly any porn site and be outside of Colorado anyway, if not outside the US entirely.

These sponsors aren't alone. Most elected lawmakers are equally bad at technology and protecting democracy from the threats that come from chipping away at privacy protection. Bills like this appear in other states all the time, despite being toothless, easily circumvented by kids (who trivially circumvent even face photo hurdles), or radically compromising the privacy of adults (like this one).

There's also the long game, where these sometimes Democrat-led bills in various states could eventually see a much deeper-reaching federal one, where, instead of a "age signal", the user's computer must send an "ID signal", allowing all personal interactions with the Internet to be tracked, analyzed for political and other biases, and used by backbone firewalls to control exactly what people are allowed to read. Very handy for a dictator who might want to block off "fake news".

This is only a hypothesis, but one has to wonder whether sponsors to such bills even care if the bills work or pass, since either way they still get to claim they Protected the Children! even though the bills themselves violate privacy for everyone, often cause websites about breast cancer to be censored, or pave the way for authoritarian control - something this one stands out for. The only thing really surprising is that this bill wasn't sponsored by MAGA Republicans deliberately to add another paving stone to the road to national censorship.

I urge everyone to get in touch with other Colorado representatives to call for a fight against this travesty of a bill. Further, I would excoriate the two sponsors by email and phone, and tell them now that you will not reward this sort of juvenile lawmaking with your vote. Lastly, tell other people about how Matt and Amy plan to strip away their privacy in a way that puts children more at risk than doing nothing.

While XML was imperfect from overcomplication, JSON is imperfect by falling short of even basic database use, and somehow despite its alleged simplicity it manages to be unstandardized almost as badly as Markdown. JSON and YAML both fail to have comments that survive processing, something it's easy to regret since XML does have comments that appeared in the parsed objects.

A saner subset of XML, possibly run through some over-caffeinated developers to lighten its redundant syntactic feeling, would have given us something FAR better than JSON's failure and YAML's gratuitously hypercomplicated syntax.

Developers Are Stupid - developer.

XDG doesn't handle complex environments, especially not heterogeneous computing environments. Something long the core strength of Unix is acknowledged by XDG and then left utterly unaddressed. Without this, the "standard" is as much an impediment as an aid.

It's amusing that modetc goes through all this effort to twist dotfiles into the XDG half-solution, and here I am using symlinks through /dev/shm/xdg/* to warp XDG into sort-of working in an actual heterogeneous environment.

Because XDG by itself is a failure beyond trivial cases.

A while ago, I just wrote a filter to be able to paste markdown into a <name>.smd file, and an Apache filter to autoprocess them much like any other filter (and a <named>.smd.meta for title info and some other metadata).

This makes it super easy to write something cool on Reddit or whatever, then just paste the markdown into an index.smd file in a new directory (named meaningfully) and poof it's in a webpage.

The core of all of it is a /var/www/cgi-bin/markdown-to-html program centered on:

    python3 -m markdown -x codehilite -x fenced_code -x toc

It's enabled in my ~/www/.htaccess of all places:

  # This works, with setup in /etc/apache2/conf-enabled/mod-ext_filter-adds.conf
  AddType text/markdown .md
  AddType text/markdown .smd 
  AddOutputFilter markdown-to-html            md
  AddOutputFilter markdown-to-shtml;INCLUDES smd

Much easier to just edit markdown (index.smd usually) and reload than reconvert, and that filter above lets you include arbitrary HTML too, critical to deal with markdown numerous weaknesses.

I just hate that (1) you can't nest anything into a table (2) it's different everywhere.

Restructured Text is much more capable, and yet here we are, still using Markdown.

My markdown pages often also have HTML in them, I mainly use Markdown so if I decide some overlong thing I wrote on Reddit actually doesn't suck, I can copy-paste it into a webpage, and my web-server's .smd handler does the convertion. Lowest common denominator. :(

Fine advice overall.

Except:

Don't put suffixes on command names. Don't. It's a DOS thing that has no meaning in Unix. It confuses users. It breaks hiding implementation details. It encourages users to do the wrong thing. It makes changing what language a script's in have a ripple effect of breakage across everything else that uses it.

Don't do it.

The general movement of UI paradigm has been from one tech to the next with a focus on backwards compat. Almost amusingly so at times, but this is how all the earlier users and use cases can most easily progress. E.g.

* hollerith cards and sundry + printer * printing teletype * dumb (video) terminal * smart (cursor addressable) terminal * images of smart terminals * images of smart terminals with color (businesses resisted color for years) * ... ?

And in the meantime we have an evolution of support for modelling things visually and working with more descriptive protocols - or even function-defining protocols to raise the abstraction chatting with the display server in realtime. In this, "abstracted" means something that can be sent over the network instead of using a local buffer. These are in a less strict order than foregoing...

* text, color plotters, VDST, and all that other old slow stuff * [skipping a bit up through bitmapped greyscale graphics] * bitmapped color graphics * abstracted 2D graphics (-> W and X) * abstracted 3D graphics (OpenGL + GLX) * dynamically client-extendable remote graphics servers (NeWS, mostly 2D) * ... ?

So here I am, waiting for the next stage in these. Hypothesizing that finally we'll get something with 3D abstracted, network graphics (display lists in GLX but accelerated with something like XCB?), where the primary display coördinate space is (x, y, x) instead of (x, y), where the client can push some code to the remote server and raise the abstraction on the fly, finally. Where maybe we'd be able to permission the objects in that space and share it among users live. Where the 2D apps would be inside the 3D space instead of the other way around. Something for the 2000s instead of familiar abilities provided in 1990.

But instead, Wayland. Wayland, which is not backwards compatible with X. Wayland, which is 2D at its heart. Wayland, another 1990 era graphics system with a super thin offering of features for actual end users (not devs) which come at substantial cost in lost X features. Wayland, which resists the one user doing things we've long thought of as normal - in the name of "security".

Wayland is not what I've been waiting for.

I can't really enjoy an article on CSS where the third thing he does is to override the USER'S PREFERRED FONT SIZE.

Arrogant.

But not as bad as those jerks that use smaller and smaller, progressively lower contrast text as the actual content gets more important. Huge readable repetitive headings, microfiche gray-on-gray for the stuff that mattered.

My theory is that this same Windows experience is also how so many joined the command-with-filename-extension cargo cult. But unix and windows work differently, and the approach does NOT port.

No, this is pretty meaningless unless sourcing in function.sh or something. If your script is short lived and doesn't have a work area (read/writing files), don't bother with cd. If it's long lived, the best default would be "cd /" or "cd /tmp" - sadly, since bash seem to mmap the script, this still doesn't free up the filesystem for unmounting. Python is different, and "cd /" is a good default for a long-lived program.

echo has long been unreliable. Even the built-in echo in the shells were unreliable in SunOS, because the shell would look at the binaries in your PATH and try to figure out whether to emulate the BSD vs SysV (IIRC) version of echo and then change what echo would do. So much for writing a single script (with echo) that would work for all your users on the same host.

This is why you'll see code like this: echo 'prompt: ' | tr -d '\012'

No other simple mechanism was portable at the time. Seriously portability-minded coders still use that line, because although the issue is finally dead in linux+bash (i.e. /bin/echo is enough like bash's builtin) - it's likely still broken in other Unixen out there.

I've had Perl change its syntax on me and break my pet monitoring system too often to make me feel good about Perl. It hasn't been too hard to keep it running (20 years so far), but starting fresh I'd probably use Python.

Python is much cleaner code than Perl for the most part as well.

However, for anything that should run forever, make sure you have a copy of all of its source code AND its libraries AND the source code for it's compiler. Repo rot is a serious problem over time.

The extensions are improper from the outset. Commands should not have extensions.

erlkonig

4년 전discuss

No, it doesn't. The extensions are usually too inaccurate to rely on. That could be either a Bourne or Bash script, meaning it could either fail at some arbitrary point during run if the wrong one is used, or just subtly, critically change some output. Much more true for Python scripts.
