I was not aware of this, do you have additional information to share?
Since the page title isn't very clear: this is a mini-tutorial on how to us a disassembler to patch the recently abandoned Twitter for Mac app to support 280 character tweets. Mods, feel free to update to a more informative title.
The article was specifically written for Pixelate (issue 5), so it was around that time. I only started hosting the articles myself after Pixelate became defunct.

Social security is meant to be a foundation, not a supplement. It's supposed be enough to live on, but not enough to live luxuriously on.
Actually, I recall reading or hearing somewhere that the negative correlation between income and number of kids mostly applies to consumerist societies, which is what much of the West has become. I can't find the source ATM, so if you know, please post.
When trains become competitive with road transport, maybe we should move more to using trains. Until then, we won't, and we shouldn't. (If it's a matter of externalities/hidden subsidies, then the costs of these externalities must be brought to the entity causing them, e.g. via taxes.)

I don't know why (in Germany) a long-distance bus is much cheaper than a train (from/to the same city), but it is. We shouldn't be trying to shift traffic to rail unless there's a good reason beyond "it feels good" for it. If it is better for the environment, I'd like to see a "citation" (not in the form of research, but in the form of well-justified taxes/tolls/... that transform this into a matter of cost).
There's an open bug in Chrome to put it in Go mode on regular hardware (crbug.com/747143).

Not sure if that would help though. The performance constraints on low-end hardware are different than on others. For instance, you want as many layers as possible on regular hardware (so transitions are smooth). However, those layers eat up RAM that low-end hardware can't afford.
Ask HN: Best learning resources for kids
Parents on HN,

what learning resources do you use to give you new ideas for helping your kids learn? These could be a blog, book, project, video etc.
If you’re about my karma, then it is not high as far as I care, nor am I too smart, as you noticed. Most of upvotes I got were stupid rants and complaints about modern ui and javascript with few points that I personally find important. I think we all differ in intelligency, understanding, style, etc, so my thought on karma is... it doesn’t matter; what matters is how one reacts to others meaning, both structured or emotional.

I don’t see why your comments have to be grey at all, if that helps, just pointed out where few may have ‘misheard your tune’. But if it is unthoughtful, then it’s their problem, not yours. They’ll use make and suffer, isn’t it fair?
Not really. People have been "window shopping" or "just browsing" in retail locations since...well the dawn of retail locations. Now they're just able to be more efficient about it.

Even the conservative assumptions of the SSA show that SS will have some funding for your retirement, just not 100% of what is current promised. (Something like 75% 30 years from now)
That makes me feel a whole lot better about the Austin Zoo. :)

And it doesn't surprise me that folks have kept them as pets. I don't really understand it and truly wish this sort of practice would stop. Or at least require people to invest time and money into special classes concerning their animal along with long-term planning for the care of the animal. It won't stop some people, though.
It seems a great many people believe that everyone else, and particularly, everyone in management, is unethical; the system is corrupt, all management is corrupt, and the only way to advance is to sacrifice one's values. I used to believe this too.

To the ethical people out there, I'd like to say that there is a battle and we haven't lost yet. It sure looks that way, given the behavior of the government, large corporations, even NGOs. But its a battle. And the first front in the battle is mindshare. If ethical people believe that everything is corrupt and hopeless, then the unethical people have won.

Consider this: the rogue employee at OpenTable could genuinely be a rogue employee. They might even be a nominal ethical employee who perceived behavior around them as unethical, or who believed that the only way to success given their performance targets was to behave unethically. They may have believed that the only explanation for the performance targets were that OpenTable wanted them to act unethically, when in fact they were just impossible targets set by an aggressive, but ethical manager.

I'm sorry to say that ethical behavior is something we have to fight for continuously. We don't get to create a constitution a few hundred years ago and call it done. But it doesn't help if we declare, as I used to, that the government has been "rooted", and the US is just an unethical cesspit now. Get involved. Demand ethical behavior. Call out moral hazards. Talk about ethics.
Is there anything on how to figure out what your retirement goal should be?

Like how am I supposed to estimate costs I will need in retirement to know how much I need to start with.
> For Firefox, it's 20100101. I don't know why.

At some point in time, that date was Firefox's build date. Then, some concerns were raised about that date allowing sites to track users based on that date so it was set to 20100101.
This is a load of crap. It's part of an entire genre of "Vietnam revisionism" that has been circulating around right-wing circles at low intensity since the late 70's. It's usually centered around the idea that we were just about to win in Vietnam, with just a couple more months or a couple more thousand troops, and that it was the cowardly liberals who snatched defeat from the jaws of victory.

The whole idea could only exist with years of distance from the war itself, once people have forgotten what the actual situation was like. None of them remember that Vietnam was what Afghanistan is today: we don't even know what "winning" looks like, never mind have anything close to a coherent or realistic plan about how to do it, and everyone knows it.

As for the specific faults with this editorial, it's right there in the opening paragraph: "He considered the Liberation Front and the North Vietnamese on the ropes, and headed for defeat." The author doesn't even acknowledge the possibility that Westmoreland was simply wrong; no, it must have been those schemers in Washington.
What exactly do you think is unethical about it? The store either has the best price or not and it is certainly within the consumers best interest to get the best usage of their money. Is it the fact that "she's standing right there"? Poor behavior doesn't make it unethical. There is no obligation to buy a product just because I am standing in the store.
Sites like reddit, Twitter and Facebook are more like feeding a dopamine addiction. It's not really a healthy break to take. Taking breaks is good if you go for a walk, talk to a co-worker, meditate, grab a coffee, do some stretches, go to the gym. Breaks are not good if you're getting your dopamine hits on various fun websites. I mean they're fine as long as you mentally treat them like having a beer or launching Steam and playing a game for a bit. Should you be doing those things at work instead of getting your work done and heading home? Probably not.
In term Rent/Salary ratio how it looks? In US it could be as much as 1/2 or more common 1/3 for a 2 bedroom residence.

Hair analysis has been proven to be largely junk science.

That's a separate issue because Hair analysis is not inherently worthless. It was just assumed to be vastly more accurate than it actually was.

You can for example tell from a hair sample is not from the same person. IE blond hair vs black hair. You can't do the reverse and tell it is from the same person without DNA testing.
I convinced my family to move to Signal. Perhaps try that.

If my coworkers were grinding through stuff that took them 20 hours, I'd be all "I work smart, not hard" with accompanying snarky eye roll, and I'd assume I could bust through an equivalent work load in four hours and still look like a goddamn superhero.

And sometimes I could, so, hey, validation!

This was me for a lot of years, then like the author I joined a really high performing team. Those guys (all men) cranked out a lot of code. I even told my wife, I wasn't sure if I could keep up. I really had to up my game, but I did find a lot of their code really wasn't the highest quality and they tended to write more code than they needed. I learned a lot from the situation, and every team since has been even more low performing. It makes it really easy to excel in the typical, Dilbert, Fortune 500 development team.

It's applicable math and a good check for anyone who wants to retire.

You are correct that reduced earnings period and a longer withdrawal period does increase risk for early retirees, though.
VRML was declarative. It was like HTML for describing 3D scenes instead of documents.

Web3D (WebGL, specifically) is imperative. It lest a program render 3D scenes by telling the system where to put the triangles on each frame.
There is an interesting article on the relationship between savings rate and number of years required to save for retirement.

Given a savings rate, the number of years required is income-invariant. (A given savings rate may not be invariant of course.)

I believe the poster above was mentioning more those that are below median income or certainly those closer to poverty levels. There are a lot of benefit programs that take number of dependents into account so if you income is remaining the same, then increasing the number of children you have increases the benefit amount you receive. I don't think you can draw a causal relationship between benefits provided (at least for many families) and increased children, but there are certain people that do know this and exploit it regularly (source: watching an in-law do it ATM).
One of the many reasons stores often prohibit taking pictures.
I'd love to see that graph continued for the last few years.

With online banking becoming more mainstream and online-only banks picking up steam, I've personally seen many local bank branches close up, and have a hard time believing that.

> So the transition–what the ATM machine did was effectively change the job of the bank teller into one where they are more of a marketing person.

Not sure if such an alternative position can be found in a cutthroat B2B market.
> For a while that was my benchmark for what was worth reading if I saw an article surface more than once it was possible of interest to multiple circles of interests rather than one, and likely worth the time to read.

There was a clever RSS reader that worked on this principle. Sadly, it is no longer being developed.

Hey, nice to see my venerable tutorial get some renewed attention. I got a lot of positive feedback on it over the years and that's why I kept it around, even though it's a bit outdated.

I'd like to do an update or write a follow up article. What would you be interested in seeing? More examples? Different concepts? Should I port the examples to a different framework?

No offense, but compare your GitHub profile to someone who "grinds" like https://github.com/bketelsen. There is far too much confirmation bias in regards to work-life balance and ability to actually produce. As far as clichés go, I believe that "if you do what you love, then you don't work a day in your life" == productivity.

Well, frankly I believe it is a biological trait, an unavoidable natural instinct manipulated by propaganda.

Humans and their ancestors survived for several thousands of years in bands and tribes with between 10 and 50 individuals. Social cohesion and collaboration among them was essential for survival in confrontation with other animals or tribes fighting for the same resources (or females).

It is unavoidable that evolution shaped them to develop a desperate wish to "belong" to a group. Some call it tribalism. Nations just grab this tribalism and turn it into ideological justification for everything as in: "my country, right or wrong". Religions, political affiliations, corporations and sport associations use that trick too.
Compare:

Noon had not arrived when the Musulmans had wreaked their vengeance on the infidel enemies of God, killing 15,000 of them, spreading them like a carpet over the ground, and making them food for beasts and birds of prey.

...and twice that value was obtained from the necks of those of his relatives who were taken prisoners, or slain, and had become the food of the mouths of hyenas and vultures. God also bestowed upon his friends such an amount of booty as was beyond all bounds and all calculation, including five hundred thousand slaves, beautiful men and women.

One of the best known of such rulers is Sultan
Mahmud of Ghazni, Afghanistan. He ruled from 997 to
1030, and extended control over parts of Central Asia,
Iran and the north-western part of the subcontinent.
He raided the subcontinent almost every year – his
targets were wealthy temples, including that of
Somnath, Gujarat.
Much of the wealth Mahmud carried away was used
to create a splendid capital city at Ghazni. He was
interested in finding out more about the people he
conquered, and entrusted a scholar named al-Biruni
to write an account of the subcontinent. This Arabic
work, known as the Kitab-al Hind, remains an important
source for historians. He consulted Sanskrit scholars
to prepare this account.
> One can easily foresee a future where a self-driving truck has a driver in it who is only driving 'regulated' hours for a small portion of a trip (say during high traffic, highway entry/exit, etc). The driver could spend the rest of his time sleeping, reading, or coding - he'd basically be a passenger.

That kinda already exists though, with team driving. Two pilots relaying gives ~22h of driving per 24h plus 2x30mn slack (under US regs, though there's still a limit of 70h/8 days followed by 34h rest per driver).
You can't beat entropy, or prevent it. All you can do is change its distribution.

So, one way to look at living things is that each one is a local depression in entropy. But because you can't make something from nothing, each living thing has to broadly increase entropy in their environment, in order to decrease it locally.

Thus if we envision entropy as a surface, a living thing is not a depression from a flat plane, but rather more like a hill with a steep depression in the middle.

But again, since you can't have something from nothing, life can't arise from an environment of maximum entropy. In order for life to come into being, local entropy must be low enough for a hill to develop. This is where the entropic definition gets into trouble, because the local low-entropy environment around here is provided by the sun. And if you define life as any local depression of entropy, then it raises the question of whether the sun is alive.

Maybe it's better to think of life as a system, not an attribute. To use an analogy, you wouldn't look at a single wave in a rapid in isolation, and wonder what it is. Without the broader context of the river, you'll never understand how the wave came to be there. If every living thing is a like a ripple in the local entropic surface, we can point to individuals, but could only really understand them if we consider the whole picture of the solar system.
While the cost of passive maglev track isn't huge, conventional rail networks which you'd be competing with already exist, so typically would only be justifiable for new networks. Safety is another large concern; it's easy to make a fail-deadly maglev train. While maglev trains are the fastest, safety keeps them an emerging technology.

There is no straightforward risk-less formula, unfortunately. You can follow all the textbook advice, have a budget, max your 401k, pay down your debt, buy a house, blah blah blah, and after 20 years still only have 1x or 1.5x your salary in total savings [ask me how I know] due to bad luck, unfortunate market timing, lack of skill in investing, emergencies, etc. I hate all this simplified, incomplete advice. If successfully saving for retirement was so straightforward and deterministic, there wouldn’t be an entire industry, with consultants and books, built up around trying to help people hopelessly navigate it.
You're absolutely right! The homeless have always been with us, and it's high time government policy caught up with that. Yet, might there be a kernel of subtlety here?

In some places, the homeless quite commonly register intersections or similar locations as their stationary home location. Then things like notices are delivered to them there. This, as grandparent implies, is not so straightforward with a mobile vehicle.

What does that leave? A requirement to constantly update your location of record with local government? Overbearing surveillance to track the homeless so government can reach them? All-electronic systems relying on devices and services the homeless almost certainly can't afford? None of these are great solutions. All are clearly problematic, in the damning social justice sense.

Again, you're completely correct. We need to admit, accept, acknowledge, and embrace our unhoused friends and neighbors. It's just possible that a truck and a tent under a bridge might pose slightly different levels of difficulty for addressing-type needs.
> Moreover, the courts "have consistently held that there is no constitutional right to housing."

I'm still puzzled at how our society affirms our Right to Life, while simultaneously affirming food, water, and shelter as Essential to Life, yet will never make the logical conclusion that food/water/shelter are necessarily included in our right to life.

1. All men are entitled to life.

2. Food, water, and shelter are essential to life.

3. Fuck you, get a job or freeze to death.
In the US, trains are for long distance and, in fact, handle a significant portion of the long distance transport that would otherwise be handled by trucks. Most trucking is (relatively) local as it is.
I always ask potential coworkers during an interview for a story like that for two reasons: 1) it'll tell me whether or not they have humility, honesty, etc; 2) and, because I love sharing war stories.

One candidate we interviewed answered my question saying that he had never made a mistake like that. Then he went on to tell me a story about how a bad patch from Oracle which he applied brought down production this one time.

The guy seemed arrogant, and I felt like he was lying or he is overstating his skills. Either way, he ended up getting hired by another team (knowing full well that we didn't like him), and he only stayed for about a month or two.

Go figure.

A mortgage is a sort of reverse bond. Ideally, you pay it off aggressively shortly before you plan to retire.

This whole blog series is great, and I'd recommend it, but this particular post is the one responsive to the mortgage and retirement part:
