That's pretty neat. Is it actually any faster than just doing four 8-bit adds, though?

Presumably it would take 4 logical instructions to do the vectored math, vs. 4 logical instructions to do the scalar additions.

I suppose you're looking at a minimum of two registers for the vectored approach, vs. 8 for the scalar approach. Having the result available in separate registers makes them immediately available for use, though.

There's also the overhead of getting the numbers in and out of memory. Loading and storing one word is obviously going to be way better than loading 4 bytes individually.

It seems to me like the vectored approach would be better for algorithms that require iterating through a large dataset in memory. The scalar approach would be better for algorithms that have a bunch of dependent calculations. Perhaps that's an obvious conclusion!

That's pretty neat though. For the large dataset scenario, perhaps you could get a significant speedup on relatively simple architectures such as cortex-m microcontrollers. I suspect that sufficiently modern high end CPUs/compilers wouldn't benefit so much from it, though? All the pipelining, superscaling and caching and whatnot could sufficiently mask the latencies of the memory accesses to the point of being irrelevant. Also, a sufficiently clever compiler could implement the loop with actual SIMD instructions and achieve significantly higher performance than the manual in-register optimization.

This would be a fun way to compute a basic 8-bit checksum on a binary blob in a microcontroller... Not that it would be practically useful because any non-trivially sized blob would be better served with at least a Fletcher checksum if not a full CRC, both of which seemingly lack the necessary associativity.
You gotta give everyone a chance if you can. I don't see why anyone should feel bad for giving someone an opportunity that is later thrown away. You did the right thing by giving someone that opportunity; whether he takes it or not is up to him.

If everyone in the world thought like you, the world would be a better place. Unfortunately, this world is full of nepotism and tribalism. But people like you (and the parent commenter) help balance it out.

Summary: An Intel CPU in "Red Unlock" mode allows any user-mode code to read and write its microcode. The paper teaches security researchers how to do it. They can use it to discover undocumented Intel CPU internals and functionality.

I don't know if these instructions will be useful in exploits. They require the CPU to be in Red Unlock mode. One known way to enable Red Unlock requires connecting a special cable to the motherboard's USB port and exploiting the Intel Trusted Execution Engine core [0].

There are probably remote exploits via ethernet and the Intel Management Engine.

Could there be some motherboards that shipped with Red Unlock mode permanently enabled? User-mode code running on such machines could trivially root the machine and even escape a hypervisor.

What do you propose, that fn add goes back in time taps the shoulder of the allocator as it's allocating what will eventually be the first argument and ask to give it a bit of extra capacity?
Maybe this is also related to the tendency to consider abandonware software which is not continuously updated. Imho sometime a piece of software should be simply considered completed, especially in the case of libraries and frameworks.

An important thing to consider when selling to BFE's is not just that their budgets are larger, but the value they will receive from your offering is bigger, too. I see a lot of SaaS founders get embarrassed about charging enterprise rates, when, as Patrick says, the rates don't even really matter at that scale. Yet while they may be able to charge 20x as much as their regular plans, they may be delivering 50x the value. Make sure you have a good understanding of how your application will provide value, and how they will measure that, not only to support your sales efforts with the customer, but so that you feel confident about your side of the sale, including the price.
For you, maybe. Some would think removal of homicidal maniac dictator that openly paid terrorists, invaded neighboring countries, used chemical weapons, mass-murdered his own population and bribed top functionaries of the UN[1] to look other way is some upside. But I guess who cares what foreigners do to foreigners, there are billions of them anyway.

The explosive detectors give false positives all the time. Any kind of lotion or hand soap contains glycerin - beep! Any kind of preserved meat product contains nitrates - beep! Fertilizer? Beep! Fireworks? Beep! Heart medication? Beep!

The tests they use are intentionally cheap and fast. Accuracy is not the primary criteria.

For white people you get an extra 30 second pat down. For brown people you get detained and interrogated all day.

Like drug dogs, false positives may be considered a bonus by the security apparatus because it allows the apparatus to work against the discriminated-against class and blame it on something else, as you have just done.
> It's profiling.

No, it's not. He was picked because he set off explosive detectors. Repeatedly.

The racial opinions of the person asking the questions doesn't change the fact that this is not racial profiling.

For my upcoming game/app (threewiki.com) I actually built all three versions : )

First the complete, native iPhone version, then realizing that parsing HTML and storing with Cocoa is a pain. (Core Data is pretty good but too bureaucratic for simple things).

So in my second version, I moved all the data logics to an App Engine server, and just leave the app with a thin UIWebView layer in most cases, and only stores the user token on the phone. Mobile Webkit is pretty accurate but I didn't like how the animation turns out, just doesn't "feel" right. Besides, scrolling is much slower in UIWebView than the native UITableView, and you cannot change the tap-link style in UIWebView except a simple color overlay.

Then comes my final version, in which I use UIWebView for static content, and use UITableView & custom views/animation when there's interaction, and all model logics and data processing done on the server.

The app feels super smooth now. And it would be super easy to update because pretty much all the logics in on the server, so app is essentially a pretty "portal". Take a look of the video if you are interested threewiki.com
Please tell me more about these SaaS ideas that will make me 400k/year.

There are historical patterns that indicate that when wealth (using the term colloquially) inequality gets too large then bad things tend to happen. Revolutions, for instance.

There is no specific damage done specifically by Larry and Sergey having become rich. There is damage if too many super rich people aren't contributing enough money to pay for national defense, roads, sewers, clean water, education, etc. They benefit from living in a society with decent levels of each of these things.

Since the middle class and the poor don't have much more money left to contribute to pay for these things then an argument can be made that the super rich ought to be taxed more. Part of the existence of income inequality comes from tax inequality. In the U.S. this is coming from the fact that much of the money the super rich make comes from capital gains and not earned income. The capital gains tax is quite low.

There is also the fact that money does bring with it power. If it gets concentrated too much into too few hands then that's a problem for a lot of people.
Groupon is becoming a massive company, and yet Andrew keeps a low profile. And, the company itself outside of tech circles, remains modestly known. Yet, it seems that Groupon is following the Facebook trajectory as this young company makes huge leaps in growth. Oh, how the two Founders differ.
If you do decide to give the pi another chance, move the root partition to an ssd and avoid the SD card woes. Or, boot from a USB device and have no sd card at all on the Pi 4. Both work well and a cheap option as you probably already habe all the stuff.

You've still got a load of wires to deal with though (unless you shell out for a fancy case).
I live alone in London (reading between the lines, I’m guessing OP is U.K. based), and find the simple act of going for a walk to get a coffee really helps when feeling lonely. Seeing other people on the street and the brief chit-chat with the barista help me feel more connected with broader society, and also get me out of my own head.

"Both sides win" when a consumer chooses to spend their money on gambling. They're getting what they pay for, of their own volition.

I consider advertising to be offensive, and think it's appropriate for a society (big or small) to control what forms of ads are allowed via law. I'd like to see limits on what sorts of trade-offs we can make with respect to ads, so that the life experience of a citizen need not be drowning in advertisement.

Riding a taxi in NYC (where ads are built-in to the cabs and cannot be stopped) is a distinctly unpleasant experience compared to elsewhere. We can only have so many forms of transit available to the people of NYC. I would rather we choose to remove the ads and pay for the transportation system via direct-monetary transfer, or taxation, or some combination. shrug
Foundationdb has ACID transactions over the entire db, over the cluster and over multiple keys. And fast.
I've looked over so many open sources alternatives, and they claim ACID but it's a deception based on some narrow interpretation of ACID. It's very annoying to spend time researching to discover the truth between the lines.

I would love to find a fast, scalable open source db that implements Foundationdb's features.

That's true. But it's also true that lot of third world people use about 2 Mbps internet or even less. Mainly they (we?) aren't used to paying a lot for internet and relative to income, it is costlier than in developed countries (due to PPP differences.)
Right. I think this is how a lot of business requirements are specified, since they are frequently constructed by non-programmers. Taking a bunch of cases from a spec document generated by a domain expert and turning them into maintainable/readable procedural code takes a lot of creativity. I think it's easier to express case analysis like this in Prolog.
I won't touch IntelliJ, but I find Eclipse good enough to work with. I've seen the syntax-errors-in-random-files bug occasionally; it's always been a block of text "moved" to the wrong place in the file. Annoying and worrying, but pretty quick to fix. Debugging has always been reliable though, and simpler refactoring works, and it's getting better at a good rate. But yeah, the problems are real.

One of the best things I did last year was updating my monthly financial reports to include a Personal Balance Sheet. It suddenly refocused us on "what will impact our wealth" rather than "how much income did we make this month". I write it longhand in coloured pens because I like that tangibility, but having some graphs etc would be nice as well.

I also add two other metrics (haven't played with the app yet, still downloading, so you may have these / others). I got them both from Kiyosaki's Cashflow Quadrant.

The first is a ratio of Net Wealth to Total Liabilities. Doesn't tell us much by itself, though it's good to see it trending upwards.

The second is the percentage of monthly Passive (eg, Rent) and Portfolio (eg, Dividends) Income to monthly expenses. So if it costs you $10k/mth to live and you have rental income of $2k you'd be 20% of the way to covering your life costs without 'actively' working. Also nice to see trending upwards.

the market that can afford smart phones but realized it doesn't need most of the features at the expense of battery life

I see what you mean, but that market still has different segments and what you talk about (phone with this feature set plus 3G/4G connectivity with WiFi tethering) is just one of them. I for instance couldn't care less about these features. And I'm pretty sure there's an entire segment which just wants a phone which just calls and texts without bells and whistles and a battery life that makes sense for a portable electronics device. Let's say at least 3 weeks. So yes with this one all I see is somthing which I can use to call and has 29 days of standby so I'm in :P Don't care about the price. Oh, it's ultra-cheap? WIN WIN :]

You ask for more evidence in the same comment in which you rant against 'so many HN searches', do you notice the inconsistency there?
India is notorious for paying shit money to people. When I started my first software job in India i was paid less than 4k$ a year, I lived in a slum and worked 60 hour weeks. I obviously did not have to pickup some one else’s shit. And I am not saying that America has a prettier picture but overall being on minimum wage in America/Europe is actually a little better than being on minimum wage in 3rd world / developing nations.
I've also noticed this, at least subjectively. I haven't done any rigorous experiments to confirm this is actually happening, but my ISP has a reputation for doing shady stuff, so it wouldn't surprise me if they prioritized traffic to speed test sites.
The US has a 1st amendment that protects the press. Russian state media must publish blatantly false propaganda. This does not mean that all US news is accurate, but Russia state media is legally required to be inaccurate. I think this is sufficient reason for censorship.

My hypothesis is that they will bring back the smaller size once the larger sizes have been legitimized. If they had simply introduced different sizes, the community might see the new (pixel) sizes as "alternative". Developers might be annoyed at having to support something other than the one-true-size-that-Jobs-left-us. Instead they dropped that one true size and made it clear that an iPhone now comes in multiple, larger sizes. These will now forever be canonical sizes, even when Apple continues the smaller size.
I can speak second hand about MMJ. I never sought to get a card myself, and I won't now that it is legal for recreational use in WA, but I witnessed first hand how it tremendously helped a friend of mine who suffers from Fibromyalgia. Before she acquired her card, she was so disabled from the pain that she would sometimes require a wheelchair and need help feeding herself because she couldn't hold utensils.

Now my observation is clearly not scientific, this wasn't a study with controls, but while I was initially skeptical of the therapeutic value as compared with other available drug options, other prescription medication did not have the same effect. She stopped taking MMJ for a short while and her symptoms returned.

I also cannot rule out that there is some placebo effect going on, but if it is a placebo, so what? In this one instance, I have a hard time believing that it hasn't helped. Her quality of life is substantially better for MMJ.

This is also why I never considered taking advantage of the system. It might have been possible for me to find some condition that would have allowed me to acquire an MMJ card of my own, so that I could purchase Marijuana for recreational consumption. What I didn't want though, was to harm a program that was successful in treating her illness nor that of anyone else for whom it helps.

I really hope that the "crackdown" doesn't adversely affect those who need it.
> One can argue that White Stripes' 7 Nation Army or Andy Warhol's Campbell's Soup Cans are not feats of technical mastery by any stretch of imagination, but the key is that there is no correlation between technical difficulty and monetary value in the first place.

I see arguments like this a lot and it think it conflates two very different kinds of "technical difficulty"—design difficulty and execution difficulty.

Given the sheet music, any guitarist can play 7 Nation Army in a few minutes. It is not physically difficult to play. Also, it's not hard to come up with a completely original melody or artistic work. Just throw a couple of random unrelated things together.

But it is extraordinarily difficult to have such a mastery of composition and understanding of what music is already familiar to people to be able to find a melody that is both original and enjoyable to a wide variety of people. The level of cultural, musical, and historical knowledge required to do that is extremely difficult and rare.

It's like taking your boat to the world's most popular fishing hole and knowing where everyone else fishes so well that you can still manage to stake out an unvisited spot that hasn't been fished out and reel in a giant.
