Operations to return string length or return characters from the end of the string become far less expensive.

You also have a fair idea of a reasonable sized buffer to move in duplication operations, avoiding single character move loops.
I'm one of the authors of this paper and this comment pretty much hits it on the head. Jolt is an investigation in developing tools to help users get more use out of their programs when the alternative is failure. Because the reality is that there will always be programs that fail.

Most of the comments here are pretty fair about where Jolt might not be applicable (busy loops) and how this approach could be integrated with development; we touch on many these points in the paper (already linked by someone in the comments).

Am I the only one that agrees with Notch and does think that this "unlimited detail" technology is a scam?

Euclideon is asking for money to develop "new" technology that in reality has been done before and does not have any advantages over a polygon based engine. Everything in their demos can be done (if not better) using a polygon based engine and modern GPUs.

Seriously, just watching one of the videos by Euclideon makes me feel like I'm watching late night tv advertisments. If their tech is as "ground breaking" as they claim, surely they wouldn't need to do as much convincing as they currently do in their videos.
Ask HN: Would you sign a "mini-contract" upon giving notice?
I just gave notice. HR has asked me to sign a 2 page statement. It's a lot of legal speak, about confidentiality and returning any company material and other bland things which I'm fine with

However, there's also things in here that I'm not in love with, like not criticizing the company ever to anyone and some pretty broad proprietary information stuff.

Why should I sign this? It seems pretty silly to bind myself to anything when there's no benefit to me.
I think the real implication is that we would have to be a Type III to survive at that point.

I suspect this is a practical impossibility. Certainly the speed of light presents significant challenges.
Wow. So when you rewrite something, it's perfectly justified. When someone else decides to do the same thing, you twist the argument around on its head. Sounds completely hypocritical, mate.

That is indeed a ridiculous quote.

Before you re-iterated it here I had interpreted it as "the big three can no longer rate the world on their own" and "DGCR will add a fresh 4th voice to the rating industry".

I'm wondering if anything has been misquoted because the literal interpretation doesn't make sense.
From the article's comments:

"Rather than ptr+len, I would use a ptr+ptr format, that automatically ports to any size word/memory/address-space without any need for adjustment. -- Poul-Henning Kamp"

"Encode the size of the length value into itself. One way to do this is to set aside the high bit, giving you seven bits of length value storage in each byte. The high bit is set for all bytes of the length value, except the last one. If there is only one byte of length value, its high bit is not set. So for example, strings of length 127 or less would have one byte of length value. Strings of length 128 to 16383 would require two bytes of length value, etc. This way the length value can have arbitrary values, yet still consuming no more space than necessary. Loading and storing the length values could be efficient with hardware support. I would suggest storing the length little-endian. -- F"

"Length-prefixed strings do have many advantages, but I hate to think of the interoperability issues. These days you're probably safe with a 32-bit length, but there'd still be systems around using 16 bits, and you'd try to talk to them on a network and things would be all crazy. Not to mention endinanness issues. As well, null-terminated strings have some optimizations you can do by pointing into part of the string. e.g. you can have the strings "foo bar" and "bar" occupying the same memory space by pointing the latter at the middle of the former. It's common to do this when parsing a string, incrementing a pointer to the part you're interested in. An alternative might be to have length + pointer, pointing to a string somewhere else (which can still be null-terminated for compatibility), instead of length as a prefix. It's worth noting that the Lua language does something like this. You might also be interested to know that a buffer overflow exploit was indeed one of the earliest tricks hackers used to get into the PS3 system. A device known as PSJailbreak exploited such a vulnerability in the kernel's USB device handling to take over the system. (And getting into the console was sort of the first step of the PSN issues, since 1. Sony reacted very poorly and ticked off a lot of hackers, and 2. PSN was designed with the assumption that anything coming from a PS3 could be trusted.)"

And more.
A gentleman's agreement that I remain a professional is free.

If you want me to sign anything contractual, I require consideration. That's how the game works. (Paperwork from HR drones verifying confidentiality agreements remain active and that my laptop is returned are free.)

If you're not a really assertive person, "Let me talk to my lawyer and get back to you." works frequently.

They may try to exert social pressure to get you to sign. I encourage use of the line "We're all businessmen here. If this is that important to you, we can find a price which will make us mutually happy." You are under zero moral obligation to comport all future business dealings to the whims of someone who once paid you money.

There's a Chris Rock line. When you're in a restaurant, you pay them money and they give you food. Once you leave the restaurant, you don't get to say "Where's my steak?!" If they aren't cutting you a paycheck any more, they don't get steak.
Just for laughs ask them how much money it's worth to them. Then don't sign it.

Well, I would certainly indicate to them that you don't see any point in signing - you already have a contract with them! It's up to them to convince you that signing is in your interest as much as it is in their interest.

Some good quotes:

Orphaned works:

There are opportunities too in respect of so-called
orphan works (Recommendation 4). The
Government agrees with the Review’s fundamental
premise that it benefits no-one to have a wealth of
copyright works be entirely unusable under any
circumstances because the owner of one or more
rights in the work cannot be contacted. This is not
simply a cultural issue; it is a very real economic
issue that potentially valuable intangible assets are
simply going to waste. The Government will this
autumn bring forward proposals for an orphan
works scheme that allows for both commercial
and cultural uses of orphan works, subject to
satisfactory safeguards for the interests of both
owners of ‘orphan rights’ and rights holders
who could suffer from unfair competition from
an orphan works scheme.

No software patents:

The Government will resist extensions of
patents into sectors which are currently
excluded unless there is clear evidence of a
benefit to innovation and growth from such
extension

Anti-patent trolls:

IPO will investigate the scale and
prevalence of issues with patent thickets,
including whether they present a particular
problem to SMEs seeking to enter
technology sectors. IPO will then explore
options for addressing any problems
identified, which could include coordinated
international changes to patent fee
structures if the issues prove to be
international in scope.

Which Antivirus Software Is Good Value For Your Money
Even if she's blogging about her experience, her feelings aren't relevant anymore, interesting story or not, we shouldn't care anymore, you can easily subscribe to her blog and read her words.

I would never call her names, but it's obvious that she's enjoying all the fame and attention she's getting. God knows when she will stop complaining and thanking AirBnB and admit that they made it up for her generously, even though they were never obligated to.

Some argue that what they did was only out of PR pressure. IMHO, that doesn't make them bad guys, working for your company reputation isn't a bad thing to do.

EJ (and others) are still saying that AirBnB should have responded more quickly, for anyone who knows even the slightest bit about businesses and entrepreneurship, it's certain that this sort of insurance policy can't be done in hours, that needs days maybe weeks and they done it well. Does anyone think they should have shared their working details with her because she's writing post after post to complain about them so they don't sound like they don't care? Some do and that is very naïve actually.

If you're implying that what I said was for karma, you can check my submissions/comments history, I'm more of a lurker here, I don't comment that much and I definitely don't care about karma (less than a dozen comments in 2 years).

I have a question for those that have done a lot of programming in Lisp: Is macro programming a really big part of Lisp programming? I mean, what percentage of a typical project would be macros?

I ask the question because you can achieve the same results in most dynamic languages by grabbing the string representation of a function, run it through a parser, modify the resulting AST and then regenerating the function string before passing to an eval (CoffeeScript being a good example of this approach). Sure, it's messier than in Lisp, but in return for the messiness of macros, you get much easier to read syntax in most of your code. Is the use of macros really such a big part of Lisp programs that it justifies the lack of syntax everywhere else?

The population of the US in 1650 was 50k. Now it's 309 million. No surprise that energy consumption increased by a factor of about 10^5.

Also, the increase in world population isn't going to go on forever. Birth rates are decreasing in most countries - including third world countries. In fact, the population of many states in India is increasing not because of birth rates but due to increasing life expectancy. I can't find a cite now, but I remember an article which expects world population to stabilize at something less than 10B. If even that number seems worrying, remember that vast swaths of land in Central Asia, Siberia, Canada, Alaska, Australia and Antartica are virtually uninhabited: we don't even need to go the moon or Mars or something to find space for humans.

We do need to get our act together but our real problems are effective policy-making and governance. Not finding endless sources of energy.

As someone who is known to hire people once in a while I always get really suspicious when "What other say about me" sounds like the stuff I see further down the page.

Who would ever actually say something a long the lines of

“Matthew brought a combination of vision, strategy and execution that can rarely be found in one individual. His brand development and messaging at launch resulted in demand that exceeded expectations…an ideal talent for the product marketing executive that is looking for the next rockstar to add to their growing team.”

I mean "his brand development..." really?

That is so written to sound serious not to actually sound like something other people would say about Matthew.

I would much rather trust stuff like:

"Matthew is one of those guys who get it. He is fun to work with and very knowledgable and have a good track record of successes"
You're right. Tactically, though, that only matters if you litigate the contract. 99.999% of contracts will not be litigated. There is business value in non-litigated contracts: if there wasn't, they wouldn't ask for it.

Accordingly, if someone asks you for a contract, you always get something for it. Handshakes are free, formalized promises five figures and up up up.

[Edit to elaborate: Most importantly, promising to do something you intend to do, or promising to not do something you do not intend to do, are not valueless. I have no intention of working for e.g. Zynga. If a company wants me to durably commit to that, though, the fact of the commitment has nonzero value to them. Even that easy to keep promise of locking in my behavior in the event of something unlikely to happen costs money.

This goes for pricing for megacorps in any circumstance, by the way. If you normally get to email in 24 hours, and they want that formalized as an SLA, that should cost an appreciable amount of money. No, not $100. $100 is appreciable to you, but if they can spell SLA, they lose precision under five figures anyhow.]
