Ask HN: Tech help for a concerned mother
MY friend called me from [redacted]. A child she had adopted and raised has been running away via a chat site with predators. She two of the user names the girl has used, and one device she has used, but would like help to prevent the girl from creating a new user name, which could be her last.
Below is her plea with contact info edited out.
If you think you can help, contact me and I will connect you.
Thanks

* * *

I have a 14 y/o daughter who has been getting on [redacted] & meeting/running away with much older men. Her latest user name is [redacted]. The one before that was [redacted]. I need to find out if/when the last time she was on site. I fear she is getting ready to meet up with someone & run again. She has done this 2 times already, but thankfully was found. She was sexually assaulted. I need someone with way more knowledge than me to please help.

I'm certain the value here comes from changing your focus and mindset. If you switch to a mode of thinking of "I ned to give you (the rubber ducky) context and explain concepts so that you can see intention and reasons for this code chage/ bug behavior". This change of mindset allows you to view and reason about things better.
Christ, ten seconds on Google for "pentagon wings 9/11" would've done the trick. The wings of a plane are basically soda cans filled with fuel.

http://www.popularmechanics.com/military/a5659/debunking-911...

> When American Airlines Flight 77 hit the Pentagon's exterior wall, Ring E, it created a hole approximately 75 ft. wide, according to the ASCE Pentagon Building Performance Report. The exterior facade collapsed about 20 minutes after impact, but ASCE based its measurements of the original hole on the number of first-floor support columns that were destroyed or damaged. Computer simulations confirmed the findings.

> Why wasn't the hole as wide as a 757's 124-ft.-10-in. wingspan? A crashing jet doesn't punch a cartoon-like outline of itself into a reinforced concrete building, says ASCE team member Mete Sozen, a professor of structural engineering at Purdue University. In this case, one wing hit the ground; the other was sheared off by the force of the impact with the Pentagon's load-bearing columns, explains Sozen, who specializes in the behavior of concrete buildings. What was left of the plane flowed into the structure in a state closer to a liquid than a solid mass. "If you expected the entire wing to cut into the building," Sozen tells PM, "it didn't happen."

Anything else trivially answerable you're interested in?
I totally agree with you, but as you know, a CPU is pretty complex and is not possible to explain it all in just one article.
Before writing it i've been looking for something similar and have not found any other article that explains as much as i've covered, so, to me it can be considered far from being perfect but "good enough".

Also, i'm technical but don't want to spoon-feed anyone, the article says what a logic gate is, how are they built and which ones are the basic ones, after that, just some wikipedia and google will be enough to teach any reader how to build the other variations, same applies to flip-flops.

I'm not witting this as rude as it looks, indeed, i agree that i've been far from explaining exactly how everything works and fit together, but i tried my best to make it simple, not too techie and easy to read, and becoming a text-book was just out of my scope.
Also everybody else would choose the degree candidate so you have no competion for the other, you are likely to get them for less money and they will be more loyal.

However I suspect there is very little rationality in hiring, even amongst this community.
If they are handled by a closed source browser extension distributed by them, how are you so sure?
And GPUs these days have their own MMUs too.
The attack in the article isn't about a malicious user eavesdropping and obtaining someone else's cookie directly. It's about a user who gets a cookie from the server, brute-forces to determine the key used to sign the cookie, and then uses that key to generate cookies that authenticate them as other users (or that execute code during deserialization, etc).
This is dark comedy from Amazon. I like it. Not campy. Pornhub apparently had a real good April Fools too.

Well done.

n/m. Doesn't look like it's done by amazon.
He should change the description from "hard sell" to "hard on the eyes."
Construction of a unit complex number though, given an angle, requires trigonometry. Precomputing this and re-using it is identical to precomputing the sine and cosine of that angle and reusing them instead - the complex number itself doesn't simplify anything here other than storing both the sine and cosine in one variable.
Yeah, TeX name autocomplete or better yet free unicode description search triggered by \ is the obvious direction.
(think github emoji search, like how :ship also offers :anchor: and :package:)

https://kasperpeulen.github.io/PressAndHold/Unicode/ was a novel attempt. [source: https://github.com/kasperpeulen/PressAndHold]
The trick is you long-press any letter, e.g. press Shift+A and don't release => you get a popup offering 𝐴 ∀ 𝒜 𝔄 (use arrors & Enter to select)
Long-pressing letters is amusingly unnatural, I have to make a conscious effor :-)

Apropos unicode notations, that demo was made for https://github.com/kasperpeulen/CoffeeTeX, a unicode AsciiMath-inspired notation.
I really like it. Might have to mimic your style for an editor friend of mine. Do you incorporate this style somehow into your business cards (if you have any at the moment)?
Uh... why is this on the front page of HN? Feels like spam but I'm probably missing something.
Hey, I remember those days. Wasn't there a 2K basic before that - and an "unlabeled" one before that? I remember an article at the time - with "Palo Alto Tiny Basic" actually listed in source format. It was generally agreed that Bill Gates simply copied that Basic from the magazine and started selling it on paper tape. Somebody at the time even did a comparison, and found that the tape was almost identical to the code in the magazine article. Should we be surprised? Another billionaire getting rich on the work of others.
You could give your feedback without laying it on so thick in that first sentence.

But I agree. A simple hello-world example adds a lot to a language's homepage.

Cool project.

As someone from the FPGA industry, bigger projects just use your CASE 3 on a board to start prototyping. A Zedboard or similar. Cheaper version could be the Zybo. It's like $500 vs $200.

When you get to production stage, you whip up your own board.

What exactly is your complaint about the propriety tools? You are using Altera tools with the DE0 Nano.
That's what anarchy really devolves into.
Well, I could certainly do that - I've already blown $40MM trying it once several years ago :) - actually it was for an aircraft with a different focus, but still ...

Making predictions is hard, especially about the future.

Building a complex system is rife with complex risks. There's the initial sticker shock, and that's even if costs can be reasonably estimated years in advance for technology which is not only unproven, but undemonstrated. Then there's the quite significant nonrecurring engineering costs. Want to divide those costs over 200 aircraft instead of 300 - bam - 50% cost increase, thank you madam taxpayer. Still need those 200 aircraft by a given date - discover it costs more because manufacturing facilities come in "chunks" of price-to-capability - under-build and miss the target - over-build and per-unit is higher. Discover your estimates of deliverability, even if made with honest efforts, are off by a few years, and the price only goes in one direction. Try to keep certain components really (relatively) inexpensive to meet price requirements, and discover, like every aircraft manufacturer in history, that adding lightness is difficult after you had to add strengthening material in certain problematic areas, like, oh, the wings. And of course, politicians change their minds - keeping 10,000 engineers engaged during a lean period so that you can re-engage them when political winds change is a nontrivial task too.

And with all that, to be a successful long term project, there's some future events that have to be estimated - tell me what the threat will be in 20 years? What will the political will to engage those threats be? What munitions will there be? What survivability is desired? What's the desired lifetime? Will AI be good enough to dump pilots entirely?

As much as I'd love to build the next generation manned fighter-bomber, it's not a palatable risk for anyone not ready to lose their entire investment. Even Paul Allen has got to feel a little sensitive at the billion dollars he lost with his effort at Eclipse (during the time I was losing far less).

I recently went through (most of) a technical incubator in the area I live in. There were several investors involved that were quite knowledgeable about aviation. I couldn't get any of them interested enough to engage in my autonomous air ambulance idea (the Marine's have said in advance they want such a thing - but it has to be good, fast, and cheap) - and the translation to a future civilian capability is pretty obvious.

That's one reason I'm cheering for the effort by Boom to build a new civilian supersonic aircraft. Yeah, it's going to be hard to meet price targets, and it's refreshing to see someone willing to take a $30MM chance on a complex project, and that's just to get a demo built and flown.

Building a future capable fighter is a whole other ballgame.
Does Scala have this kind of dependent types? What does Idris type system provide that Scala doesn't support?

It's not about the person, or his job. It's about the clever concept.
> Because under the conditions of contemporary Capitalism, believing in venture capital as your ladder to the moon is as mythically fictitious as your description of unions.

We have before us, in the form of Y Combinator and other accelerators, many examples of successful businesses started using VC by ordinary people such as you and I. And, as a former resident of Detroit, I quite assure you that my portrayal of unions comes from observing their behavior over quite some time and I am far from alone in having first-hand experience with their, shall we say, drawbacks. So forgive me if I fail to see the "mythically ficticious" bits here.

I will agree that many modern worker protections do stem from the risks taken and sacrifices made by organized labor nearly a century ago and that we ought all to be grateful for that indeed. However, that was then, this is now. History is fine but what unions are in the United States today is something that many software professionals, including myself, don't wish to be a part of.

These days you don't even submit them via a kernel call these days; you've got your own GPU MMU context so you can kind of just go to town within your own process.

That's sort of the whole point behind Mantle/Vulkan/Metal/DX12.
There is this myth about the correct way in which one should code a game, entity/component is just the current fad of the decade, previously it was OOP.
It's more like: if you lost your keys on your way home, you go and look for them under the lamp post because you're drunk and you can only see where the light is.
Good idea for business cards like this. Could leverage multi-design printing such as Moo's Printfinity[0] (allows for a different design on every card).

No, but thanks for the ad hominem. I mean, the discussion is obviously about me.
You've also have Singularity style software isolated processes where the OS statically verifies memory safety so that it can safely run all of the code in ring 0.

This isn't a tech problem. Unless you watch them all the time and/or imprison them, you can't stop someone in the US from accessing the internet. It's free at the library and inexpensive in many other places.

Your friend needs professional help from one or more of the following: psychologists, counselors, social workers, or possibly even law enforcement (to prevent these men from meeting her daughter in the first place, if feasible).

Perfect example of a clever functional component to convey your business / sell yourself.

One usability note: I would turn 'less / more hard sell' either side of the slider into links that move it forward/back as keeping my mouse pressed down on the slider reading through all the options was a little cumbersome.
Its rare that you come across a unique personal pitch tactic with this much selling power and focus. For me, this was one of those rare occasions where it actually happened. This guy seems very good at what he does.
Yes and no. Defensive driving in Portland against pedestrians and bicyclists is required well above what I'd grown accustomed in other cities. Yes, they have a right. They pop out and around the cars in expected and very much unexpected ways.

This reminds me of a sailing lesson. Smaller vessels have right of way. Sails have right of way over engine driven. A friend of a friend was sailing and came close to allowing his 30 foot sail boat to be run into by a mega ocean fairing cargo ship. He saw it coming at him, had plenty of time to drop sail, but refused to take action because "he had right of way" completely ignoring that the cargo ship needed a mile or more to meaningfully turn out of his path. The sailor was right. Right but stupid. Stupid might mean dead, and stupid people dying is evolution at work.
I think the purpose of that sidebar is to list the names of relevant configuration keys for some frameworks. Pretty confusing though.
edit: to clarify, when submitting orders to an electronic exchange, traders will call out (to themselves) the price size direction and instrument before sending the ticket. I personally also mouseover all the important parts so i'm not just going through motions.

this method seems particularly effective for work that is routine but never in the same scenario. Ever since I picked up this habit I have applied this to everything else I do - booking flight tickets, hotels, buying things on amazon, etc. avoiding errors is so much of a good thing - for those of you with really bad experiences firefighting at work will know the importance of not being in the position where you need to firefight at all.
It’s probably a generally better idea to use a polynomial approximation if you have a floating point unit; a degree 8 polynomial for sin(x) on the range [0, π/2] gets you to just about the limits of single precision floating point. If you only need about 4 digits of precision, you can use a degree 5 polynomial.
Cancer, like aging, is an example where much of the research community is undertaking very challenging and expensive work with marginal expectation value because that dovetails well with the types of fundamental research that can be funded, not because of any expectation that it is the best approach with the highest expectation value. This is an age of genetics, genetics is popular, and so people are getting funded for personalized medicine and ever more intricate mapping of cellular biology.

But there are hundreds of types of cancer, and taking the genetics/drug discovery approach for each of them is its own distinct and massively expensive undertaking. It'll never get done: the research community and its funding sources are not large enough to make significant progress on the whole of the problem in the next few decades. This isn't hacking cancer, this is hacking the cancer funding institutions in order to obtain funding to get on with the fundamental life science research goal of mapping all of cellular metabolism. Cancer is the excuse, but not the goal.

This is a cultural problem.

Hacking cancer would be to sit down and say, ok, the economics of this are not working, we need to find common points to target, a way to produce a universal cancer therapy at no greater expense than one of these single cancer therapies.

Some immunotherapies, like CAR-T approaches, are a small step in this direction, something that can be applied to multiple cancers with a lower cost of customization per cancer type.

The best target, however, is to block telomere lengthening; disabling both telomerase and alternative lengthening of telomere (ALT) mechanisms. This is a small area of biochemistry in comparison to the scope of most single cancer explorations. All cancers depend on telomerase or ALT or both. All of them. No exceptions. No cancer can evolve its way around a suppression of these mechanisms. It will simply die, losing its ability to replicate uncontrollably. Some noted research groups are making early inroads into disabling telomerase in a targeted way. ALT remains to be dealt with, but is easier to work with than telomerase interdiction by virtue of the fact that ALT doesn't happen in normal cells.

A telomere lengthening interdiction treatment would be applicable to all cancers, and it doesn't appear to be more expensive to develop than any other approach to a specific cancer. That is what hacking cancer research looks like; identifying a way to completely change the economics of the situation, and redirect the primary effort back to producing an effective cures as soon as possible.

Lastly, I have to fundamentally disagree with the final lines of this article; cancer can absolutely be dealt with robustly by killing cancer cells. You just need to be selective enough, early enough, and comprehensive enough, and raising the bar on these items is the whole point of the field.
Honestly, one thing I like about HN is that these sorts of corrections are made, and made respectfully.

Their post was interesting because they're right: I'm a native English speaker and I paused on "medicament".

Most agencies already use the internet with VPN's and the cell system. This will give them a dedicated LTE radio band but I think the towers and backhaul to inet are the same with some sort of prioritization.

If you are the skeptical of the government type though it is true they could shut down the public bands and keep band 14 up. Probably not though, they will just just get backhaul priority and the public bands will be jammed up if something bad happens.

The only time you need to start with an angle is if a human or other external system is feeding it to you, and the only time you need to convert to an angle is when you need to present the data to a human or other external system.

The point here is that you can usually get rid of evaluating transcendental functions in the middle of the number crunching part of your code, which is where you would care most about saving operations.
That's only one indicator of it's potential quality. You can also judge (and price) a film by the caliber of actors in it.

But sometimes that doesn't work - Kevin Spacey, Jennifer Garner, and Christopher Walken -- should be a total winner, right? Not always...

A friend of mine does something similar.

Long story short, he uses a foldable bluetooth keyboard and his phone cover as a stand (that folds too).

Not much really, once you a mean to get an ssh terminal you're ready to go.

But quite frankly, I find it quite a waste of money and time. Such setup is practically unusable for anything useful.
