The main obfuscation was the way IEC 61131-3 constructs get first compiled to C and then to assembly.

There's a lot of indirection and zero strings in the resulting code, meaning it's very difficult to actually find whatever logic you're looking for. But once you see it, it is obvious and seems like it was built like any other logic.
It gets spent on awards and grants to non-browser related things that please the CEO and board:

Time to decentralize everything. I think we are already in the early stages of this new trend. We can run AI locally and hard drives are so large we can have a local copy of an entire library, with millions of ebooks, in our own home now.

That is in addition to generating our own energy off grid (so no smart meter data to monitor), thanks to the low cost of solar panels as well.

Bye bye Big Brother.
The dystopian part is that they're testing a CV feature that has enough capacity to watch tons of streams constantly, and they don't _need_ your permission to run it. One would hope this will put the "haha my FBI agent must be bored I'm not worth it nothing to hide :)" fools in their place

For me it's the Firefox sync feature. I install Firefox everywhere so I can instantly be up and running anywhere with all the settings, bookmarks, open tabs, logins, and addons ready to go on any new computer. It's a huge convenience and time-saver.

Most of the problems I have are that when opening a new tab, FF does not show the content. I need to copy paste the url to another tab, and then it works.
I'd rather have some uncouth editor berate me in a discussion than my personal editing experience of sometimes having simple and obvious, even clerical changes to non-contentious topics immediately reverted with no comment.

It's not that I take it personally, because I realize that no one cared to review the edits before reversion. It's just that "be bold" in the sense that it's applied by me in combination with how it's applied by overprotective bots (maybe?) or at worst diligent but careless editors is a massive waste of time and energy. So I've stopped contributing altogether.
It's an absolutely valid observation and I cite it often. We need to learn as a society how to separate things and think less wholesale.

The best people have silly beliefs, the worst people have great insights, and the vast majority of us are in-between.

If we discard everything "tainted" by imperfection, we'll be left with nothing good.
This is an interesting method to advertise. I can’t say I like it or hate it but certainly, it’s better that advertisers are being more proactive.

Sure? There is nothing about upperclass-hood that implies that it is desirable or infinitely maintainable. In fact, beyond the romanticizing of the upper-class we see in popular culture, I suspect most actually prefer to be working class, especially when coupled with an upper income. There are way fewer nightmares when your only concern is showing up to work.
If you care about the web, use Firefox. It's as simple as that.

Yeah, sorry, Hacker News has successfully made my server chug a lot :)

I'm working on it right now and hopefully will be working better soon! In the meantime I've increased timeouts so loading will be longer but it should work better.
Get Financial Data of 345 Companies Within 40 Seconds with the FinanceToolkit
The Finance Toolkit this is an open-source toolkit in which all relevant financial ratios (130+), indicators and performance measurements are written down in the most simplistic way allowing for complete transparency of the calculation method. This allows you to not have to rely on metrics from other providers and, given a financial statement, allow for efficient manual calculations. This leads to one uniform method of calculation being applied that is available and understood by everyone.

Through threading it can get you financial statements, historical data, ESG scores, ratios, performance, risk and technical indicators within seconds for any amount of companies. Try it now.
Basically "supercharge" but in a use not specific to the literal raising of intake manifold pressure and flow. To "supe up", also spelled "soup up" (which makes no sense to me as there's no broth involved), has been a common term in motorsports since at least the 1960s.

Really good article and it's great to see this come out right after the fiasco of Sunbird / Nothing Messages.
Never before in history has it been necessary. It used to be possible to travel like a hundred miles and dissappear. Before credit was ubiquitous, money was hard to trace, and before that is was essentially untraceable. And cameras didn't used to be everywhere tracking faces for criminals and frequent shoppers. I don't know what privacy technologies you are talking about that are super effective, and i have been bit older than 10 for a while.
I used to just buy a couple 5 gallon jugs and refill them at the market. Then I would keep a 2 gallon dispenser in the fridge. Now I have an RO unit and just refill at my sink.

Although, one thing to keep in mind is that RO units typically waste a lot of water. For every gallon of filtrate they produce, they also dump 5 gallons down the drain.
Well the error message claims that they are infringing copyright. It very well could be that they are within their rights if the initial license/contract stipulated that they would only service the trains in their authorised locations. This should be illegal, but very well might be.
Of course it seems weird... if you read what I said I implied it's not really rational.

But no one's brain is saying "wow the lack of motion blur really affects the realism here".

I walk into a house and see a TV show playing on a TV with interpolation turned on and it just looks weird because of how TV looked growing up. I mean that's just the simple reality of it. I understand when film nerds come along and explain motion blur etc but that's all very "system 2" thinking. I'm talking about pure system 1 subconscious processing.

What's even weirder is how some folks can never seem to grasp why their explanations of how motion blur is bad can't convince others to suddenly like interpolation.
That is more the API testing level, it's an application logic thing. In theory, you can output the values of interest into the logs and use log analysis. Or you could expose them as metrics like other values with https://openmetrics.io/
That guy clearly has never been around 10 years olds, and vastly over estimates their intelligence.

I'm fact, all evidence points to younger generations being less tech savvy because they don't have to troubleshoot like the older generations did. Everything works, and almost nothing requires any technical configurations.
It's either that or they are referring to the board being useless against the CEO. Usually the board is the only group keeping a CEO in check. Honestly don't know from the tone of the comment though
Sure, depends on how you encounter it. Most often on forums someone will show up wanting to hear about how to write a strategy, and they are rebuffed with "nobody would ever publish that".
> Never in the history of humanity has such powerful privacy tech existed for anyone who wants to use it.

True.

> it's trivial today, even for a non-technical 10 year old

Not even close. It's difficult even for a technical 30 year old.

You're talking about acquiring cash that has passed through several people's hands without touching an ATM that recorded its serial numbers. Using it to acquire Bitcoin from a stranger. Making use of multiple VPN's, and making zero mistakes where any outgoing traffic from your computer can be used to identify you -- browser fingerprinting, software updates, analytics, MAC address. Which basically means a brand-new computer you've purchased in cash somewhere without cameras, that you use for nothing else -- or maybe you could get away with a VM, but are you really sure its networking isn't leaking anything about your actual hardware? Receiving Bitcoin, and then once again finding a stranger to convert that back into cash.

That is a lot of effort.
> or any combination of praenomen, nomen, and cognomen that was sufficient to distinguish them from other men with similar names.

Even Julius Caesar's full name including all three parts would not be helpful in distinguishing him from many of the other men in his family.
The timing was terrible for me lol.

All the ads on Twitch had pushed me into paying for Turbo.. and now they're advertising in chat and embedded in people's streams
Thank you for linking that, that made me laugh out loud. That should be a scene in Idiocracy.
It will be interesting to see whether the AI recognizes olde timey mountain dew logos, and whether or not it recognizes a "DO NOT DRINK THIS" sign above a mountain dew logo. I suppose no publicity is bad publicity, so they probably don't care.
I've found inheritance to be a problem with pretty much any ORM I've used extensively (Django, Hibernate, NHibernate, Entity Framework). It helps to design your OOP model with that in mind; having no more than one level of inheritance, and using inheritance only to supplement a set of common records seem to be good enough rules of thumb.
Web devs do not love to take it away from you. However, designers, product owners and project managers do.
I have been making small contributions for fifteen or so years. I don’t much feel like doing it anymore after a spurt of bad interactions.

About a year ago I created a Wikipedia page for a TV personality and author I enjoy. Spent literal hours on it collecting citations and what have you. Within a couple hours the page was deleted for not being noteworthy. He had his own TV show, has multiple published books and a popular podcast. Seems noteworthy enough to me, but what do I know.

A couple months ago I tried to create a page on a local tractor company that used to be really important to my hometowns economy. There was an existing section about the company on one of their specific tractors pages. I used that with its citations as the basis for the new page.

I did scan the citations and they seemed fine. I even fixed one that was broken with a wayback machine link. What I didn’t do was read them word for word. Well turns out multiple sections of the text I had moved from the tractors page were straight up lifted from their sources. Within 5 minutes of posting the page, someone else did read my citations word for word, and it was marked for “rapid deletion for copyright infringement”. No chance to explain. No chance to reword. Just gone completely and I didn’t have a local copy of the article.

It was particularly frustrating because the moved text only accounted for about 20% of the page by the time I was done.

Beyond that the history of my author page is now marked with a copyright infringement warning that if I do it again I’ll be banned.

I don’t think I want to play in their sandbox anymore.
> How often have moviegoers been told that they are obliged to like a movie because of the genders/races of the actors?

I don't know, how often? I'm genuinely curious because as a movie-goer, I've never been told that I'm obliged to like a movie because of the genders/races of the actors.
You can't use traceroute for switching as it operates on layer 3. Switches use MAC addresses, not IP. Switches are essentially transparent as they just forward traffic, they don't route.
Honestly yeah I had to read it a couple times, I didn't notice the joke right away, cause there are people out there who justify CEO salaries, I just can't remember the justification offhand.

Maybe if you'd referenced Chernobyl I would have picked it up sooner. Or THERAC, that's a classic.

A good way to begin to understand about toxic comments is to look for the "dead" comments on HN.

Dead comments fall into a few categories: trolling, advertisements, conspiracy/culture war and toxic.

It's pretty easy to figure out which is which.
That makes sense. When you accept Bitcoin payments and run your own node, you vote for the rules that your own node enforces.

But to me it looks like people think just running a node is like voting for the rules on that node. Even if you do not do any business.
AI allows companies to skirt laws. For example, a company may be forbidden from collecting information on individual people but that rule doesn’t apply for aggregated data.

AI can be a deployed ‘agent’ that does all the collection and finally send scrubbed info to its mothership.
Is it a feel-good emotion if the emotion is "how do I get off this planet"?
Don't know, the pro LGBT stance of Mozilla/ Mozilla Foundation was not new in 2014 I believe.

So not having leadership with opposing view does not seem strange to me; donation was done privately but it end-up being public enough. There's enough hypocrisy and pink-washing ...
That part of the article was just wrong, to be fair (I used to be head of the front-end community at GDS and helped set things like browser support schedules). Our default approach was to add up all browser share (yes, based on GA, but this was a while ago) until we got to 99%, then removed the browsers that were left over. So typically we wouldn’t consider dropping a browser version until it was less than 0.4% usage. You can use a colleague’s client-side tool to test this approach: http://edds.github.io/browser-matrix/ (assuming it still works).

The browser support is currently listed at https://www.gov.uk/service-manual/technology/designing-for-d... . The mention of 2% is specific to IE11, so I guess this was special-cased at some point.
The equation is $$$ X ability to capture $$$.

US is oversaturated with products, solutions, competitors, etc...
Yeah, because I am using highligher for code fragments in markdowns, will try to optimize it.
I don't think the USDS makes all or even most of the current federal gov websites.
How do the charging times compare? That’s the deal maker/breaker for long road trips greater than 500 miles, or shorter trips where you use all the accessories, encounter lots of hills, etc not possible on a dynamometer.
I tend to try and give them the impression that I'm gullible enough to maybe fall for it, then say I quickly need to do an urgent thing like move the washing to the dryer, put them on hold, and later check how long they stayed on the line, all hopeful that they may have found a victim. The record so far is almost a quarter hour.

It's definitely the best target to optimise – the more time they waste on you, the less time they have to work on some poor soul who's actually vulnerable.
That just says "there's less activity", and doesn't address bawolff's question of quality in any way.
Now they should add the option for viewers to opt in to this and the streamer can give them channel points (or whatever) every time the viewer drinks a mtn dew can in front of their camera (verified by the AI)! The AI will also randomly occasionally select a viewer's clip of them drinking a can to show on stream in a small-ish box on the side similar to the automated reading of donation comments!

(this is sarcastic, but it's also the next logical step for this kind of marketing)
> On Chrome, I can fire up an incognito window, type a magic keyword, do what I need, close the incognito window and go back to default.

You can do the same on Firefox (at least developer edition). I thought that you want to do that without going to incognito mode.
Seems inevitable enough that we may have to accept it and try to work within the context of (what we'd tend to think of today as) mass-spying.

I mean, even if we pass laws to offer more protections, as computation gets cheaper, it ought to become easier-and-easier for anyone to start a mass-spying operation -- even by just buying a bunch of cheap sensors and doing all of the work on their personal-computer.

A decent near-term goal might be figuring out what sorts of information we can't reasonably expect privacy on (because someone's going to get it) and then ensuring that access to such data is generally available. Because if the privacy's going to be lost anyway, then may as well try to address the next concern, i.e. disparities in data-access dividing society.
Strange how none of those listed are Mozilla...

I gave up contributing to Wikipedia when I looked back and found how much had been deleted. The deletionists have won the war.
Performance of Firefox has steadily gotten worse lately. My bank's website has massive lag when scrolling (1 second to redraw? Great!), but it works perfectly fine in Chrome. Firefox also gets into a state where screen updates in Streeview are laggy after anywhere from a few hours to a couple of days, but I can't figure out a way to predictably reproduce it on demand. Meanwhile, Chrome is snappy all the time. I also have to manually enable one of the acceleration settings under Linux. The end result is that I'm forced to use Chrome more and more as the Firefox user experience just plain sucks in these scenarios.

I wonder how well this architecture (including privacy preservation) would work for LinkedIn messaging?

Specifically the BPN service since that seems to come from a data center IP and more likely for Apple / others to have a choke point.

Crowd fund a popular "family vlogger" (maybe one who does more DIY type projects) to make an episode where they clean a bunch of motor oil, grease, and brake fluid off their driveway with MTN DEW. "Wow, it's so good at penetrating the cement and breaking down that toxic sludge!"
Distinguished engineers aren't really 'staff-level'
Interesting that three so obviously intelligent people could get the odds of the bet wrong: it’s not a 1:5000 bet, it’s a 2:5000 bet a.k.a. a 1:2500 bet.
It does seem counter intuitive.

> How does efficient and affordable transportation increase the cost of housing?

I'm not familiar enough with this organization, but "efficient and affordable transportation" is sometimes a euphemism for anti-car policies.

> How does a diverse housing stock increase the cost of housing?

Again, the specific positions can change everything, but this could mean opposing 5-over-1 development because there's "too much" already.

The curvature of space time depends on the distribution of mass and energy within that space time. If you're modeling general relativity classically with quantized mass and energy at very small scales, stuff gets "weird". If a particle isn't in a well-defined location with a well-defined energy, then what is its effect on the curvature of space time around it?
