> It's really not. Imagine a file system where all the "real" file locations are hidden, and the visible file structure just symlinks to these "real" locations. Practically no overhead at all. There will be a minor performance hit with uncompressing files before starting a program, but that's about all.

Are we talking about the same thing? It's a:

- pseudofs

- in userspace (IIRC)

- which parses multiple archive files

- and vends their contents as unionfs

If this bought you anything at all useful, then maybe it would be worth all the complexity involved ... but it doesn't.

> That only works when all applications are written using those standard libraries, and that doesn't always happen, even on OSX. Why punish software developers for wanting to use libraries that better suit their needs?

It's not punishing developers. I've shipped software for Mac OS, Mac OS X and iOS for 15+ years, and believe me, being able to ship custom versions of libraries without having to deal with a package manager, library incompatibilities across applications, et, al, is an advantage.

> The system was not built as a successor to the original Mac OS. The BeOS team were led by ex-Mac people, granted ...

Led by ex-Mac people, including the former CEO of Apple. Targeted at the BeBox (PPC) and PPC Macs. Shopped to Apple for purchase. It was intended to be the successor to MacOS that Copland wasn't.

> As I've said before, the idea behind BeOS was to look to the future, not to be tied to the past.

Then maybe the new Haiku leadership should stop blindly copying what they're familiar with from Linux.
Couldn't agree more - focus on OKCoFounder - great a novel idea, could potentially be a thriving community of tech talent seeking on another. You're onto something here
>>Without setting up the language environments? I doubt it.<<

You seem to have run nbody.python without setting up the language environment for it.

I'm going to ignore all the rest of your editorializing and try to find something of substance.

Let's just note that you've jumped from #3.1 to #12.1 -- ignoring #3.2 which checks for problems and the subsequent sections that work through those problems and explain some of what you later find so puzzling.

>>Where is that INI file? The README doesn't say. Oh its my.linux.ini (its not mentioned anywhere in the document).<<

You seem to have found the ini file.

>>No comment on what %X or %A may mean<<

Actual comments on what %X or %A may mean:

; %X %T %B %I %A in commandlines are replaced like this:
;
; nbody.python-4.python %X = nbody.python-4.python
; nbody.python-4.python %T = nbody
; nbody.python-4.python %B = nbody.python-4
; nbody.python-4.python %I = 4
;
; %A = [testrange] value or 0 when the program takes input from stdin

>>What, only python? Oh, I need to copy the programs from the "bench" dir. Where in the readme does it say that? Nowhere.<<

You don't seem to have read sections #3 through #11.

>>Okay, did that, re run the script, and it runs all nbody and regexdna benchmarks, and none of the others. Why?<<

You don't seem to have read sections #3 through #11.

>>Oh, it uses an old way of importing GTop<<

That actually is worth updating the readme about!

>>of course, I had to remove everything in tmp/* before re-running the test, otherwise it thinks there is "nothing to be done".<<

No you didn't. You don't seem to have read sections #3 through #11.

>>No summary dir here.<<

That actually was a bug! Empty directories weren't included in the snapshot zip.

>>improve readme by...<<

You didn't seem to read sections #3 through #11 (very important)
Ask HN: Do you get pain in your finger tips from typing all day?
I figure I can't be the only one who experiences this. The constant pressing all day of both work and play is taking a toll on my fingers. I am now experiencing pain after using a keyboard for not that long. Is there a specific type of keyboard that helps mitigate the pain? Any advice would be greatly appreciated. Thanks.
A social contract is a good thing, but I don't need a corporation. I can make a free choice.

Yet even if I like the concept of workers being compensated at their marginal productivity, it's a sad thing this choice will no longer exist for most of the people who are now graduating, and that entrepreneurship becomes a choice by default.

Diversity (as in having many choices - to work for a big company or for yourself) usually is a good thing.

Of course, you may still work for a big company, but if you know you are to be poorly treated anyway, while bother doing more than the bare minimum? If you have a good idea, why bother sharing its profits?

I'm always amazed by these startups doing what _seems_ like really simple optimizations and reaping these enormous benefits. If your tools support profiling, you should at least give it a shot once in a while. The fruit are hanging low indeed if Github can reap this kind of reward with this small a tweak.
Say you're running a problem of size N on a processor with a cache of size N/2. Adding another processor with another N/2 cache means your whole problem now fits in cache, so you'll probably suffer fewer cache misses, and thus could end up running more than 2x faster.

Wikipedia also points out possibilities at an algorithmic level: https://en.wikipedia.org/wiki/Speedup#Super_linear_speedup
I wonder if MtGox is re-evaluating their move to the US.
I'm surprised they were able to use CapitalOne's P2P at all, unless their volume was quite low: P2P has a $5000-per-day aggregate transfer limit.
My wife is the author of this. Here's maybe my favorite excerpt:

"With separate money we’ve got a whole new class of conflict resolution. We still debate, negotiate, argue, ... but any decision has a fallback resolution method as definitive as voting would be if there were an odd number of us. That's right, we use auction-based decision-making in our family. Where’s my nerdcrown?"
Scripts will still work as long as they have the standard #!/bin/bash at the top.

Aliases - in .bashrc - unfortunately will need to be replaced by Fish functions; defined in the "~/.config/fish/config.fish" file by default.

The only real thing that keeps tripping me up with Fish is that it doesn't support shortcuts like "!$ ". I keep on typing that in, but due to the nature of Fish, it can't (or won't) recognise it. But the excellent history functionality does make up for this a fair bit.

Having said that, Fish is by far the best shell I've tried. I gave zsh a go for about half a year and got fed up with the autocompletion and general slowness. As a shell, Fish just behaves quickly and fairly naturally, with few exceptions (!$ ...).

I highly recommend it as an improvement over bash.
Holding cash does not enrich anyone.

In an economy with a deflationary currency, those holding cash get relatively richer without doing anything. So yes, it does.

Most genuine credit card users are not aware of chargeback possibility

Of course credit-card users are aware of the possibility of chargeback and contesting payments! Everyone gets screwed by dodgy online retailers sooner or later and goes through it. Where the hell do you live that consumer rights are so secret?

it cripples the whole economy.

No, it enables the whole economy, without the possibility of getting cash back from vendors, e-commerce would never have taken off. It's a guarantee to us, the consumer, that we will get what we pay for and even if you disappear off the face of the planet we won't be screwed.

Sorry you don't like it. Everyone else really does, and we have learned through the whole of history that salesmen will rip us off at any given opportunity. Consumer protections are skewed in our favour, and they should be.
I'm pretty sure the NY banks have things they think are much more important to worry about currently - people "leaving the system" isn't a blip on their radar yet.
OP links to a copy of the email I received this morning.

Yet another company with a far too relaxed approach to security. What bothers me though is that they discovered this 2 weeks ago and I'm only hearing about it now.

That's not being fair, that's regurgitating corporate pablum. Similarly to how every scandal in congress is blamed on a low ranking staffers whenever possible, corporate scandals are blamed on subcontracters whenever possible. Don't think for a second a company as profitable as Samsung doesn't know what it's marketers are doing.
I would guess complex objects - containers, or strange databasey stuff.

The way to deal with is __complex__ as a method on the object and recurse through asking the complex method to return nested simpler python types.

You're right. But the fact that he received so much disappointment so quickly means that those venues aren't working - yet...so yes, room for innovation.
your django app doesn't look like a django app.

the basic premise of the django defaults is that app modules are pluggable and self-contained. all of the static assets, templates, model code, view code, migration files, management commands, etc. related to a particular app should go in that app's folder (which is treated as a Python module with its own __init__.py file). conventionally the app's folder is a first child descendant of the top level project directory (i.e. its in the same directory as manage.py)
Look great. I like that it is not just video but with text explaining it. Thanks ryanflorence.

Just curious, is it a different effort from the embercasts?
I just yesterday wired Bitfloor over $1000, and they have yet to acknowledge my transaction. The money is gone from my bank and is currently in limbo.

I'm frustrated that they have given so little information out, my recent transaction represents 100% of my disposable income. Perhaps part of the fault is mine, but I thought they were reputable and no warning was given. They are also no longer accepting deposits or acknowledging any in progress deposits.
Any chance of updating the website to be more mobile friendly?

This would be used in a chosen plaintext attack, right? If you saw a ciphertext C1 with IV1, and you were able to choose the following Pj and predict the corresponding IVj, then you could verify whether the plaintext of C1 was P1~ by choosing Pj = P1~ XOR IV1 XOR IVj, so that Cj = C1 iff Pj = P1~. This would allow you to test likely values of P1~ from a dictionary.
Google Apps was down this morning too, wonder if there are any similarities.
How old are you? Do you heavily use your fingers in some other activity (guitar, rock climbing, etc.)?

We are arguing about the wrong two questions:
1) What is the right value of 1 Btc? $0 or $100, or $1000?
2) Can it replace government issued currencies?

The right question to ask is
3) What is Bitcoin good for?

It's not currently good at storing value over the long term. Short term it worked most of the time.

And that's been the pattern in the bitcoin economy: Transfer globally, or in transactions where other payment options are prohibitively expensive, and exchange bitcoin for your local currency by local and transparent means.
The FinCEN guidance explicitly states that Currency Exchange regulations do not apply:

http://fincen.gov/statutes_regs/guidance/html/FIN-2013-G001....

"A person must exchange the currency of two or more countries to be considered a dealer in foreign exchange. Virtual currency does not meet the criteria to be considered 'currency' under the BSA, because it is not legal tender. Therefore, a person who accepts real currency in exchange for virtual currency, or vice versa, is not a dealer in foreign exchange under FinCEN’s regulations."

Edit: Just need to clarify that Money Transmitter regs do apply.
I hope you don't take it the wrong way. I'm not criticizing residen.se - I'm just praising okcofounder a hell of a lot.

But, hey, good response to being rejected. At least you're doing something about it.
Full context, in a recent post jared admits/confesses:

I "invested" $1,000 in BTC during the early hype as it was approaching $32.00. I told my co-workers how cool of a concept it was and that my investment was sure to pay off with a skyrocketing price.

After months and months the price drops and drops. My $1,000 is worth $200. I go through a ridiculously long process of proving my identity to Mt. Gox and Dwolla just to get real USD back at 1/5 their original value.

Now if only I had kept it in there for the long haul, I'd have my $1,000 back.

It's precisely this volatility that personally makes me skeptical of it truly reaching a critical mass of any sort.

About a month ago Comcast doubled the speed of my connection for free (50/10 -> 105/20). I was delighted as I assumed it meant that a competitor was rolling out fiber in the area or something, and I was very disappointed when an hour scouring the internet for announcements revealed nothing. Somehow I don't think that was the intended reaction.

Then again, Comcast tries to get me to "upgrade" to packages costing half as much as my current one on a regular basis, so who knows what they were going for.

Yes, you are absolutely right with Bitcoin being a means of proving a transaction. But the journalists aren't going to pick up on that distinction soon.
This makes me wonder if they had taken their user dollar accounts and bought bitcoins with them to try and make up for the shortfall, then were impossibly wiped out by the crash.

Maybe there's a sidepoint to it - that it really isn't as expensive to build the last mile as telecoms have been claiming.
It's not a strawman, it's called argumentum ad absurdum. If we take his premise as true:

> If some one is good, they will win anyway. If they are not, they can't and won't.

The conclusion from that is that the lack of women in tech is because they're not very good at it. If women were good at tech, then from his statement there would be more of them (they would "win anyway").

This is clearly absurd - hence he's wrong, or at least needs to support/make his argument a little better.

Do I really need to stick </sarcasm> tags on everything?
looking at their twitter history it looks like they had bank accounts closed on them left and right. They had a lot of different people depositing cash in different places, lots of wires maybe ach.

I am sure the fraud/risk/laundering scoring systems see that kind of thing as 10 different kinds of trouble.

Risk management is controlling your exposure to potential problems, not reacting to proven problems.
I don't know that you would be insulting actual economists. You learn pretty quickly that EMH is an abstract model and should be treated as such. It is unfortunate that such caveats rarely make it across campuses into business/finance departments. The article itself clearly falls victim to this and commits the further sin of casually dismissing the transactional uses of bitcoin.

EMH has issues and bitcoin may fail, but it is unlikely to be for the reasons the author cites.
Samsung's antics are hardly contained to smartphones & tablets either.

My guess? They had two avenues to get local cash into the system, CapitalOne P2P and Bank of America (LocalTill, LLC). By taking cash, LocalTill, LLC would be required to be registered as a money transmitter in NY State (as well as the token FinCEN registration). They almost definitely were not, so once identified or threatened, they probably closed up shop, closing off that route of funds. If the exchange's bank account was also with BoA, they could have easily identified that and decided they didn't want to be a part and would close it. Something similar could have happened at CapitalOne if the P2P TOS were being violated in some way.

edit: For those that don't know how LocalTill operates -- The merchant would forward a "deposit" to LocalTill and one would be instructed to deposit a dollar amount plus a processing fee with a unique # of cents to LocalTill's BoA bank account. Upon electronic notification that the amount was received, LocalTill would send the money minus their fee on to the business which set up the transaction.
Bitcoins may be hard to "fake", but not hard to steal. People are generally more familiar (currently) with physical security then digital security.
With OKCupid, I thought it was implying the selection process is "just OK" -- as in it's a sort of effective but not perfect matching system. Not that the people found are only OK (I personally only ever found crazy people, but I know a few people who got married from OKC...)

It occurred to me that I'd ended up somewhere obvious as I hit reply - but two days in a strip-lit barn in Earls Court can do that.

But to be fair, in book publishing the problem is deeper than web search - you need to be a better curator because the consumer investment is bigger.

Hitting a search link is close to free for the consumer, but accepting a book recommendation is relatively expensive, both in time spent sampling and pounds sterling. So good curating has greater value.

I'm going to be less happy if the third book on the recommendation list is the one that hits the spot if I've had to purchase and start to read recommendations one and two.

Beginner's Guide to OpenStack: Basics
This article has the right idea, but is obsessed with money. Money is not the fundamental motivator for all entrepreneurs. There are plenty of people who would rather work for themselves and barely be able to pay rent for the rest of their lives rather than work for a large company simply because they will be more happy doing what they love and barely managing to feed themselves than they will doing something they hate and having all the money they ever wanted. They don't care about the money, they care about doing what they love to do. So long as they can feed themselves and find a roof to sleep under, being able to work on something they love to do will trump everything else.

Immigration Bill Simplified: 5 Proposed Changes For High-Skilled Immigrants
Regulations certainly apply. For example, in the case of Bitfloor's local BoA deposit, a third party was accepting cash deposits and forwarding the money to the exchange. That requires the third party to be a money transmitter and could have repercussions if the bank account was also with BoA.
