CRCs make sense for a quick sanity check for short messages sent over serial links. But nowadays there's a much better, very well specified, method for checking the integrity of data blocks or files, and that's SHA-256. I don't think that anyone has even found a single example of a collision for it. (Yes of course collisions exist, they're guaranteed once you go past 32 bytes of input).

SHA-256 is truly a "no brainer" for a lot of different situations.
Wow. Ok, I was afraid that this copypasta account was going to bring up "slam-dunk" fallacies to bring me to shame, however woefully misunderstood.

Let me spell it out for you - Just because some women happen to identify with the GooberGater movement doesn't mean that GooberGate is not, at the very LEAST, misogynistic in tone. If you can't understand that then there's nothing that anyone here can do for you.

That's what I was thinking. In my head I was seeing something still connected and that once it's actually airborne the craft jettisons the power cables.

Or maybe there's a way to fundamentally re-think how we're designing airports.

I've been struggling with this all the time. For example, for months, gcc wouldn't compile on Yosemite, and all packages that depend on it (as there's no version on dependencies, it assumes it requires the latest), even if it's pinned, they still start installing the latest version! Compiling some packages takes hours on MacBook Air. Also, many binaries are hosted on SourceForge, and even upgrading to a point release requires a pull request that needs to be reviewed and approved! I've been waiting weeks to have Terraform upgraded, and I gave up and install all HashiCorp tools myself, not using Homeblew. That's why, I think, it just doesn't make sense in the world of Linux as it doesn't really have a true version and dependency management, it doesn't have things like virtual packages, and other basics, but I'm sure many people who are not comfortable on Linux, but are familiar with OS X and Homebrew, will use it on Linux. Gnome has PackageKit [1] (supposedly cross-Linux), and there's also Zero Install [2], but, honestly, I haven't used them and I don't know if they are any better and work for anything, but GUI apps. I personally started a Bash-based package manager, but having Bash 3.x as a requirement is tough as I cannot use associative arrays - I wonder if I should require v4 and above.

I can understand it looking like a derail. If this were a forum for the specific discussion of women's tech issues, I would never have brought it up, because it would be the wrong place.

What I'm trying to do is not say is "harassment hits everyone really hard, and I find is strange that articles about women being harassed hit the front page disproportionately more than articles about men being harassed."

This is not a commentary on "the real issue," it's a meta commentary. I can't see reason why there's not room for discussion on both within the comment threads.
Going into protmode in the boot sector is extremely early. Most OSs I've seen will stay in realmode (or "unreal" mode) for a little bit longer, so they can use the BIOS to setup some more stuff before making that leap.

Also noticed a minor optimisation:

mov AL, [SI] ; pega um byte da string e carrega em al
inc SI

Could've been replaced with a 'lodsb', saving 2 bytes. Ditto for MOV BH/MOV BL with MOV BX. :-)
I would hope that these big services, like Facebook, use content matching techniques to quickly filter out repeat submissions...
Thank you, you have answered many of my questions.

I've myself tried to acquire VC funding and built my own MVPs, and gotten nowhere. It is not as easy as I thought it was.

I grew up poor in a poor St. Louis neighborhood. All my father could afford was a Commodore 64 and I was laughed at by the IBM PC and Apple 2 crowd. My high school didn't teach computers so I volunteered for the desegregation program to be transferred to a magnet school on math and science that taught on Apple // and IBM PC systems and it was an integrated classroom.

I had a friend at the time I got into an argument with, he claimed computers were a fad, going nowhere, and that I should try to become a sports star instead. He said in ten years that Microsoft and Apple would be out of business so there is no reason to learn computer programming. He went for Football and injured his knee and lost his scholarship but remembered the talk we had about computers so he went into learning computer networking and did better.

Our high school had an anti bullying policy and zero tolerance on racial slurs. The high school before I transfered was full of bullies and they used racial and homophobic slurs. Picked on me for being a nerd and geek.

So yeah it depends on the high school, it also depends on the support of friends. If I had listened to my friend that computers were a fad, I wouldn't have gotten to where I went. It was because of his statements that he influenced others not to study computers because he was popular and I was not popular.

I find that we need more statistics on these subjects to fully understand them better.

But I want to state that white privilege thing, I had a really bad childhood growing up and was picked on and bullied and harassed a lot for being a geek and nerd. Looking for a job was tough as well, I had to do temporary light industrial jobs and work in fast food even with a computer science degree until I was able to earn minimum wage at a computer shop building computers and then it lead to another job as data entry which led to another job in programming. I never had it easy, and even had times I went without a job and looking for whatever I could find.

Diversity is a good thing, and I'll tell you why. People of diverse backgrounds have different ways of observing things and figuring things out and might notice something someone else might not notice. It might be a product or service has a flaw in it that gets noticed before it ships, it might be they make an improvement on it. If a business discriminates against people they are really setting themselves up for failure by hiring all of the same group of a type of people.

But my story, I worked so hard I got a stroke in 2001 and ended up on disability in 2003. Trying to recover from that, but once you are disabled, nobody takes you seriously anymore. I assume my career is over? Nobody seems to be there for us who have a mental illness, esp when we developed it in the line of duty.

Counter-example: Spain has a very high rate of home ownership and its economy isn't doing so well.

The truth is that we don't have enough data points to conclusively state that home ownership is tied with a healthy middle class and healthy economy.

A healthy middle class and healthy economic are more dependent on housing affordability regardless of whether or not that affordability involves renting or buying. If I were a government, I would optimize for how much people are spending on housing as a percentage of their income.

The number one source of income we should try to keep in check in society is income from economic rent in all its forms.
Amazon barely makes a profit. They are an anomaly from the dot-com days. The fact that they aren't making as many sales doesn't surprise me.

I buy in bulk from Amazon on a monthly basis. In the entire month of September, I almost couldn't order anything because of the errors during checkout. Just looking at the marketplace (and looking through the seller forums), many, many sellers were having problems (and sales dropped dramatically). Amazon denied this of course.

If you start selling a lot of a certain product, Amazon will eventually compete with you by going to your supplier and buying products in bulk..and selling these products at a lower price. At some point, you may be asked to "prove" your are a legitimate seller by providing all of your "suppliers". Why there hasn't been a class-action lawsuit against them is beyond me.

They have been tightening the ropes on many of the categories and pushing out all of the smaller sellers. If you get pushed out, you basically lose your entire business and customers in a split second (you aren't allowed to contact any of your customers directly anyway or get their real email addresses).

Selling on Amazon does nothing to actually further your business along and is like building a house on quick sand.

Amazon constantly abuses their monopoly position and deserves to be driven out of business.

Bezos has also been pushing for the Internet tax. Why? Because small companies won't be able to keep up with all of the regulations.
A well-raised point. Not colourblind here, but as someone who remembers the days when visual cues were used, I feel your pain.

FWIW, I find using `tab` to bounce around links in the main text helps. Further than that, if you use `vi` on sundays, both pentadactyl and vimperator have a "hints" mode to navigate links by keyboard, which also helpfully highlights them.

It would be nice if web designers weren't such idiots about accessibility, but these options make fending for yourself a bit less frustrating.
Your experience is that you are less viable as time marches on? Or you perceive older people to be so?

Coming from Lyle McDonald, one of the most respected trainers in the industry..

"Some of this also comes from the still gross misconception that ‘muscle burns a ton of calories’ (a myth I took apart in Dissecting the Energy Needs of the Body – Research Review). That is, they hope to jack up metabolic rate by increasing muscle mass. Which is a futile activity because the effect is minimal (on top of the fact that the obese are already carrying extra muscle mass). A pound of muscle burns about 6 calories at rest, you have to add a ton to impact on metabolic rate (see also the next issue I discuss, low metabolic rate isn’t a problem). And that takes a lot of time, time better spent focusing on active fat loss."

Basis for this accusation? Can't find anything about it except for from Stormfront and Alex Jones, neither of which count as basis for anything. It is Godwin if you accuse people of being Nazis without evidence, FYI.
Nice work. Your predicted result gives you a nice hypothesis to test the calorie in calorie out model. Surprisingly accurate! It was also interesting that the prediction tended to overstimate the weight loss. Something systematic that needs adjusting?

I'd love for someone to do this with beer.
Good point, I agree. Girls in tech are hilarious, like shrimp in ice cream
Specifically that the redacted parts were to ensure the safety of the people involved was what I meant by the pieces that should be redacted. Hiding names and details which may harm people is responsible, but not publishing whole pieces of content, I think, makes WikiLeaks the 'editor' of information rather than 'liberator'.

I don't think I said that political agenda's can't be lead by humanitarian agendas, if I did, that isn't what I meant, but not every humanitarian agenda is also a political agenda.

I do believe that Assange has a humanitarian agenda, but that doesn't mean he doesn't also have a political agenda, and those two may be different things.

It sounds like you're doing an adaptation of Inbox Zero anyway. It's Inbox-Starred rather than Inbox Zero, which to me sounds like what someone would do if their email didn't have an archive option. Or for people that generally don't like archival.

Personally, I didn't like archival at first, but now I'm quite addicted to it

Full Disclosure: I'm a Inbox Zero-er.
It would be fine it they were really just following the "we collect information about you" part, but what they seem to be really doing here is more like "we send unique identifiers associated with you to every other site you visit."

In fact they even say:

We do not share any information that identifies you personally outside of Verizon as part of this program.
That's who you target first, to spread it toward people who aren't so technically inclined. iPhone wasn't for moms at first, and now many don't know what they'd do without it
I saw all of the dead comments, and my first thought was that the mods had probably done a good job of cleaning up the vitriol. I was curious though, so I enabled showdead, and while I'm not sure that I agree with many of the dead comments, most of them are not noise. It's clear that there has been some emotional voting going on.

"There is an obvious question what happens if there are two unique constraints on a table, and the answer is quite simply that it breaks down in that case. If there are two uniques MySQL will not give an error but just execute the operation as if it was happening on the first row that matches. Essentially the where is extended to be be an or for any of the unique constraints compared to the values from the insert statement. This is obviously dangerous and definitely not optional."

I doubt that contributes, because it's not just limited to humans. Females of most species live longer than males.
The channel is a good rule of thumb. For consumer isps eu-west should be faster in the uk. On continental europe, africa, and the mideast eu-central will probably be better. The notable exception is france, there it depends on the network as to whether eu-west or eu-central is less latent. Either way its normally +/- 20% or 5ms.

Or just ignore all that and use route 53 latency based routing for your dns records. It will return the record for the least latent endpoint, per client.

It’s not ok to treat people worse because of their weight.
> our obsession with certain abstractions (the poorly defined "real vs superficial", "honor", "the dignity of work"¹...etc)

Let's conjugate together: "I understand X, you believe Y, they are obsessed with certain poorly defined abstractions T, U and V" (after the old saw: "I am erotic, you are kinky, they are perverted").

You reel off things like "Freer sex, freer entertainment, more automation, more leisure" as if all these things are an a priori universal good while values that you don't prize are wrapped up in a snarky prelude (people are apparently "obsessed" with "certain abstractions" that are "poorly defined"). Later on other people's ideas about the meaningfulness of life are presented as "cultural ideas" that "many people" don't question. Hilariously, you then go on to sense "condescending overtones" in a cartoon....

To quote the Dude: "Yeah, well, you know, that's just, like, your opinion, man."

I tend to think Gamergate was a brewing culture war that was just looking for a spark to start the fire. Gamer culture has had a persecution complex for well over a generation, particularly with respect to the press - even the gaming press. Being repeatedly insulted and attacked by the media has made them circle their wagons instinctively. Combined with a substantial fraction of gamers that are intensely misogynistic and this ugliness was practically inevitable.

The problem is that gamers picked a fight with SJWs, which are effectively their own mirror image - the same obsessiveness and mean-spirited put-downs and in-group high-fives. I mean, the fact that the SJWs are right is almost immaterial - in the words of The Big Lebowski: "You're not wrong, Walter, you're just an asshole". Online social justice groups have a knack for utterly alienating and insulting everyone they could ever hope to convince, even those who broadly agree with them.

Combine that with Gawker media's spectacular ability to stir the pot, and a few prominent right-wing culture-war bloggers feeding the gamer-gaters' persecution complex, and we're seeing outright radicalization.

You isolate and insult a guy and then give him an online culture of like-minded outcasts and they start encouraging each other to do drastic things. There are obvious parallels to other movements of angry young men...

It's a perfect storm, and it's only going to get worse before it gets better since anybody who's trying to talk the gamergaters down from the ledge has to have infinite patience for their monomaniacal rationalizations. They see themselves as the defenders of rationality surrounded by SJWs who fling glib insults... and gaming is founded on endlessly grinding against a pointless task for fun.

It's profoundly sad to see so many gamers rally behind that gamergate banner. To see harassment and threats and ruining women's lives become the public image of core gamer culture.

I'm really worried that this is going to get worse before it gets better. The "us vs. them" mentality of the hardcore gamer world is too old and well-established, and everybody else involved is either feeding into it or is drowned out by the din.
I started my company in 2001 and then in 2006 was doing well enough for my husband to join as Director and 50% shareholder.

Since then we've launched a successful product (http://grabaperch.com) allowing us to move away from doing consultancy work, our second product launched yesterday.

It can be tough, we talk about work all of the time. However there are good points. We decided pretty much on a whim to relocate to somewhere we fancied living - as the company is just us two permanently we could do that.

It is a great thing to feel that as a partnership in all senses we are building our future together. The flip side of that is that when things are not going well we tend to end up going round in circles a bit as we only have each other to talk to on a work and personal level.
The thing that confuses me (as a non-"Gamer" netizen) is that I am constantly bombarded with the "meta' arguing and hand-wringing about "GamerGate" on HN etc, but have yet to see anything actually from the core activity of the "movement" or whatever.
Yes, that also struck me. This guy obviously knows his stuff now, but he would have been well served by (American style, which I don't know if there is a similar system in Poland, so this point may be moot to his particular case) an introductory Machining course at his nearby community college. Some of the mistake he made early on are very basic. But then he learned from them obviously, and he's also seems rather very determined. It's a great story and website.

Of course, I'd also say that for many people, a typical type of reaction to CNC machiningi is: "Oh, you just put the file of your 3d part in the machine and it makes it!" Nope, not that easy.

Judgement based on long experience can be enormously valuable. You may see in your client's current circumstances a dynamic you worked through 30 years ago. As a result, you may save your client a month or two exploring solutions you know won't work for them.

That's incredibly valuable. Consider that when pricing your services.

That said, an introductory book that the local community college just recently started using (before that, there really was no book, just blueprints and notes because so much information came from the instructors) is the Precision Machining Technology [0].

Unfortunately, like many textbooks, it's not cheap. But it's a nice introductory book("I don't have a clue, but I'm interested in the topic")

It depends on who youre serving. Ams is nice for western eu traffic. Fra is certainly well connected to the continent also. Additionally fra has much better connectivity to the periphery of europe, including mid east and north africa. Additionally dub already covers the uk, where ams would cut 10ms from your fra times.

So if youve already got dub and you want to cover more of the map fra makes a lot of sense.
I find this very unfortunate to be honest. Instead of allowing dissent, the people here are actively deleting speech that they disagree with. Imagine if a conservative professor at Stanford silenced supporters of Edward Snowden.
