You are probably working directly with native formats embedded in PDF without even processing the visualized elements. Adobe tools like to do that.

Sometimes, publishers make their PDF e-books from printed source in which images are “optimized” to low quality JPEGs, but next to them non-display Photoshop data streams with pristine megapixel illustrations are kept. If you catch big PDF files, check their insides, it's one line of `mupdf extract`.

With 60GHz it would take a storm with a rate of rain approaching 55mm (2") per hour to exceed a 20dB fade margin. That is quite a severe rain. A slight rain shower should not significantly impact a 1.5km link at 60GHz.

I work for a huge enterprise software vendor and even internally I’ve heard the rise of the cloud as “don’t have to talk to a sales guy as a service”. I was sitting in the room when one of our clients got fed up with our sales process (we’ll have a quote to you in two weeks) and called a competitor, who had a solution spun up in AWS in under 5 minutes.

Unfortunately enterprise sales are a self perpetuating cycle. Vendors do it because customers want it, and customers do it because that’s how the vendors are set up to work, because customers have been demanding it for so long.

What those customers actually want is long term stability and someone to blame when things go wrong. The drawn out sales cycle is just one manifestation of that, but doesn’t have to be the only one.

OLTP in this context is indeed online transaction processing.

This general approach of «let it "crash"[1]» or happy path programming is what I used when I wrote OTLP systems for mobile networks which were performing financial transactions. The exception handling would allow you to write fairly complex business logic and relying on exception handling to recover to a stable state.

[1]: Crashing in Erlang terms is not at all what people generally mean with crashing. It is a very unfortunate word because in part many of the problems in node.js comes from joyent not understanding what "let it crash" meant - it did not mean let the unix process crash. Erlang does one process per transaction and they are incredibly lightweight. Some details from joyent can be found here: https://www.joyent.com/node-js/production/design/errors

Yes, life is dangerous, yet sadly most parents today take the approach of avoiding all dangers at all cost.

And of course you should not leave dangerous things around and make it as safe as possible, but how can one learn, how to deal with dangers, when all the slightest dangers are removed? That will only hurt later on.

One have to play with fire, to learn how to deal with it. If parents forbid it completely, kids will just burn stuff on their own. I did ... and luckily I never burned anything down. But friends of mine ... allmost burned down a village.

If you're a new parent and haven't heard this advice before, this is one of the key takeaways. It also applies any time young kids are playing out of sight. If your kid is in their room and it gets quiet longer than usual, it's a good idea to go peek in on them.

For me it is not about the showmanship, I am not the type to even take a picture of my food. What I did do though was grow up in a family of good southern cooks on both sides of the family, so I had a foundation in cooking from a young age and developed a taste for quality. I can tell how something is made by tasting it, flavor is all I really care about in food, as such I became interested in developing flavor from a young age. I attended culinary school because of that and though I wanted to be a chef until I got a real job in a commercial kitchen and quickly revised my dreams away from the culinary arts all together. About the only thing I engage in showmanship on when it comes to cooking is BBQ Brisket, I am pretty damn proud of mine as it is a hard art to master.

Okay, I'll say it: there are things that could save the life of a few children that we should still not do. We could save the lives of more children by 24/7 surveillance and GPS tracking of all adults and children. Even more if we gave law enforcement the ability to activate a disabling implant at will. Should we do that?

"But the children!" has its limits; it's not an argument, but a cynical attempt to make your opponent look like a jerk if they persist in disagreement.

So we're all fucked. By this reasoning no bridge is too far. Chip every citizen like a dog? Why not, it might help save a child. Government controlled cameras in every domicile? Of course! What if it helps save a kidnapped child!?

Justice is not about "doing everything possible", it's about balancing the rights of victims with the rights of the public. If I'm a distraught parent, I might want to ignore this balance. But the government should not, no matter how much I want them too.

Hello all! I'm the creator and director of the LibraryBox project. Sadly, the project is mostly ceased for a handful of reasons. As noted here, Matthias stopped production of Piratebox code, which was the underlying basis for LibraryBox.

When the FCC passed the rule a few years back that 5Ghz chipsets had to be firmware locked, the hardware that we mostly relied on dried up. Rather than producing 2.4-only devices or leaving the 2.4 unlocked, manufacturers like TP-Link just firmware locked everything. This killed the MR3040 and MR3020, and without those as primary hardware targets, development stalled.

LibraryBox never pivoted to the RPi, for a few reasons...the biggest being that for most of our development, the RPi didn't have onboard wifi, and driver support for USB wifi dongles was a horrorshow. The other big driver was that LibraryBox always focused on the lowest possible price point devices, and the RPi was never the cheapest, so it was never our focus.

The project is "dead", in that there's no ongoing development (unless someone out there wants to jump into the GitHub). But I'm keeping it up because there are still pockets of the hardware out there in the world that people might want to convert.

Easy answer: As someone who's used Vanguard for index funds and the like for a couple decades now, I had no idea they had an app or commission-free trades. They don't market this at all.

As a secondary answer, normal, mainstream brokerages have pretty bad tech, tbh. I don't expect it to be worse than Robinhood in terms of things like security, and I expect UX to be worse. (Side note: I just discovered that Vanguard actually has a secret security key option hidden under Account maintenance, so I can finally switch from sms 2fa. +1 to Vanguard.)
If they both work for the same organization to achieve common goal, communicate through some interface they agree on, having to coordinate occasional changes that affect both codebases, than no.

If they are completely isolated, than yes, but its really rare scenario.

There are two ways that exceptions create problems not present with other error-handling approaches.

One is that the effective behavior of a function can be changed with no change to the function itself because of an exception thrown "over its head" from something it calls to something that called it. This makes both human and machine analysis significantly more difficult.

The other, somewhat related, has to do with performance. It's easy to do a function-by-function analysis of runtime in error and non-error cases, and those analyses are readily composable. With exceptions, it's much harder to predict how much time will be spent unwinding through M functions, calling M*N destructors, etc. This is exacerbated by the fact that exception-oriented languages also tend to encourage idioms that involve many more possibly-expensive object creations/deletions (including the exception object itself). "Zero cost abstraction" is true much less often than people seem to think.

If you're concerned with ensuring that a given piece of code will never exceed a certain execution-time bound, your job becomes at least an order of magnitude harder with exceptions than with plain old return codes, even if the two seem equivalent at some higher conceptual level.

By default, every function call--including external function calls--can cause an exception to be thrown. Any unresolved function call now causes an extra edge in the control-flow graph that goes to what is effectively a return in the function. This extra edge is also harder to manipulate for normal CFG optimizations (e.g., splitting critical edges or duplicating nodes).
I agree with your two examples (malloc failure and hard drive issue).

> They are errors but trying to handle every little bit of how a computer can go wrong is not really a feasible task, although you might be inclined to handle some.

Though, using error values, it's not that different.

1. check if the error is something that you care about

2. if not, check if it is something that you should pass back to the caller (in general that's an assert "if not null/empty"), if it is then return it

3. otherwise continue what you're doing in the current function

You have the same result without a need for exception, you only handle what you care about in the current scope, or let the chain of callers decide what they want to do with the error.

My point was to highlight that it can be as complicated as you want to make it. It depends on your goals, some people are OK with stock from bullion so people want the flavor of a stock from scratch but most would agree that the latter is going to be far more flavorful and thus considered better. It depends on your goals but soup can be complicated, if your goal is better flavor than run of the mill.

>An exeption were these orange things you strap onto a child's arms, and inflate, which they can't really remove by themselves.

Those are widely considered NOT safe, a non-swimmer child is probably much safer without them than with them, as using them lulls the caregiver into a false sense of security and they pay much less attention to them. They also teach children the wrong posture for swimming/floating, which can be difficult to unlearn. In the US the common wisdom says that if you use them you must be in arms reach of the child at all times - but that's what you'd do without them anyway, so what's the point?

The idea that you'd leave a non-swimmer child unattended with them is, frankly, horrifying.

This is was my impression as well, hence asking. I dimly recall him getting zinged by some fringe enforcer group once or twice, but not because what he was saying was genuinely heterodox, simply to tighten the overtone window a bit on that side.

I agree with him that financial independence and a bully pulpit give one freedom and, as a public spirited person at least, responsibility to make use of that freedom to voice otherwise supressed opinions that merit some airing (whether correct or not). If he's actually doing it, it would certainly enhance my opinion of him.
Or you're incorrectly trained. You should always be able to flip and float on your back if push comes to shove, and in that position you can swim just using your arms.

I'm not sure what inflatable things exist that go on a child's arms and they can't remove themselves. Water wings are considered quite unsafe.

Is it possible you are thinking of something like Puddle Jumpers (look up an image online), which look like water wings but strap behind the child's back, and don't actually inflate? Those are, indeed, considered safe.
