It can matter when you put it in a scanner though. I tried scanning some old photos, they look horrible compared to even my puny 8mp camera. Then I tried scanning a piece of cloth, and was blown away by the detail..

We take for granted the "modern" security tools and libraries.

But at the same time, one would typically assume that something as large as OpenSSL has been reviewed and tested...
There also appears to be more hardware documentation available, which is always a good thing.
Here's the discussion on that Dell issue. https://news.ycombinator.com/item?id=7205759 "Simply said, the sound card outputs at max 10W, and the speakers only can take 6W in, and neither their BIOS or drivers block this."
There has been a lot of talk about quantative aspects of but little about the qualitative. What does a 18khz square wave look like wher recorded and reproduced in 44.1 kHz. How is phase affecte?. Phase of an audio signal reaching the ears helps you perceive distance and position. How many samples are used to represent the frequencies at the higher end of the audible range. What is the quantization error difference between 16 and 24.
And if the author can't hear the difference between 4bit audio and 12bit audio I question what he/she is listening on. The aliasing would be HUGE.
Wow, this is the absolute wrong way to ditch a free plan. Holy shit!

The post comes off really condescending towards the beta users that helped get the product off the ground.

Sure, the business lessons are valid and helpful (despite being a complete regurgitation of advice espoused by people like Rob Walling and Patrick McKenzie), but IMO they don't belong in the same post that tells a cohort of your very first users:

"Yeah, we needed you in the beginning to test our idea and product, but now you're a burden. Get lost."

Grandfather your free plan beta customers in. It's the right thing to do. The free plan, IIRC, had a really low ceiling in the amount of data that could be collected--like 150 people or something silly.

Lessons for SaaS founders:
1.) Don't have a free plan.
2.) Don't set an expectation that there will be a free plan to get more early testers.
3.) Don't ever refer to any of your customers (free or not) like they're a number in a spreadsheet.

(Is it just me, or is the trak.io blog theme eerily similar to Signal v. Noise?)
An article attracts discussion is good? sure. I did not know about trak.io, now I do. The attitude in the article towards "freeloaders"? not so good. I won't argue whether it is better or not to have a freemium for "your" company. But commitment should not be broken so nonchalantly. Did you at least grandfather beta customers to a free plan? If not, you did a bait and switch, and that does not make me wanna do business with you (and I would have become a paying customer).
If you read carefully, parent included a stipend ("cut everyone a check for the same amount each month based on the revenues/spending"). Flat tax plus a stipend produces a progressive overall tax rate.

http://en.wikipedia.org/wiki/Negative_income_tax#Flat_tax_wi...

Edited to add: It's worth noting, though, that you can't produce every possible progressive tax rate curve with this method. It's certainly possible to prefer some curve that is unattainable this way. But a simplistic "a tax flat in dollars is regressive in utility" isn't applicable.

One of the biggest root causes of problems in the security industry is that often the only way to make a name for yourself is to cause pain to others. (It's not too hard to convince yourself that those others deserved it.)

If you went back in time two years and fixed the Heartbleed bug, no one would be writing newspaper articles about you.
> How can they not be vulnerable?

It very much depends which variant you have installed. 10.04 is not vulnerable at all as it runs with 0.98.something (with some backported fixes, not including the exploit). 12.04 was vulnerable (it carries OpenSSL v1.0.1). There is a very similar situation with Debian's OldStable and Stable, and no doubt with the stable/long-term-support releases from RedHat and everyone else.

It also depends what they are testing: some things might be complied against GNUTLS instead of OpenSSL. That has had a vulnerability in recent months too, but is completely unaffected by this one.

If you are not using HTTPS (or other TLS wrapped protocols) at all on those servers then you are never going to be susceptible to this particular attack at all. OpenSSH apprently does not use OpenSSL in a manner that exposes he problem, so if all you expose is HTTP and SSH then you are fine (though if your users are sending anything sensitive over plain HTTP they are at risk from other problems).
Most reports about Heartbleed kept repeating that the vulnerability was introduced 2 years ago (Dec '12, which isn't even 2 years - but anyway) it was committed to a version of OpenSSL (v1.0.1) that wasn't widely distributed until the middle of last year.

The time surface of the Heartbleed attack is a lot smaller than what most think. Debian and the BSD projects moved to v1.0.1 earliest, around March/April last year.

We have a free plan, but its limited. Ours is a communications product (sococo.com) and the free plan supports a small number of simultaneous users. Paid plans increase that limit.

We track plans carefully. A certain fraction stays in the free plan, keeps using it regularly, and that's fine. But another predictable fraction moves up. We can pretty much tell which fraction that will be - there's a critical mass of usage that takes off.

So our free plan is a money maker - every month it grows our revenue stream. We'll never get rid of it.
I visit Inbound.org. To be honest, after awhile you'll see the same stories/thoughts pop up over and over. It's also more of a feed than a discussion group like HN.

>> Wastes space? In an age where we stream gigabyte movies? Do we need to remind the author that we're no longer in 1982 and that we have evolved beyond floppy disks?

Clever way of leaving out just how much space it takes up (takes up 6 times the space [0][1]) also as both this author and Xiph concluded you can't really hear the difference. When we stream HD (As you put it "Gigabyte movies") we are getting a clearly superior product. I can easily see the difference between 480/720/1080 whereas I seriously doubt I can hear the difference between 16 and 24bit audio. Yes space is cheaper than it used to be but it's neither free nor unlimited, not to mention the primary way people listen to music nowadays is probably on mobile devices where space is still at a premium or they enjoy their music via a streaming service a la Spotify/Rdio/Google Music where bandwidth is at a premium (And storage factors in here as well due to either being able to store less songs locally or in cache due to larger file size).

This is why I hate property taxes. It means that I can't just buy a house and live in it. I have to make sure my house doesn't get too expensive for ME to live in. I can't just look forward to retiring in my house. It's taxes until I die.
Ask HN: How do you get and stay in the "zone"?
I have heard HN'ers describe being in the "zone", a mental state where you block out the entire rest of the world and are extremely productive.

I used to be able to get there regularly, but I went through a stage in my life where I had an enormous amount on my mind, and hence a lot of serious distractions. Life has since calmed down, but non-serious distractions have taken the place of the serious distractions.

I am fortunate to have blocks of hours at a time where I have nothing to attend to but my own work. What are your mental strategies for making the most use of them?

Thank you!
Simple, but not so simple
Rust does allow you to implement low-level things in itself, by giving an escape hatch into C/C++-like unsafe code (i.e. risk-of-incorrectness is purely opt-in, rather than always-there).

Examples of things efficiently implemented entirely in the standard library in pure Rust (well, with some calls into the operating system/libc): Vec, the std::vector equivalent. Rc, reference counted pointers (statically restricted to a single thread). Arc, thread-safe reference counted pointers. Mutex. Concurrent queues. Hashmap.
It's quite easy to argue that actually. People pointed out that those Snort and other IDS rules were inadequate as soon as they were released, yet it hasn't stopped vendors from claiming they offer protection.

Hi Matt - I'm an employer from RAC and quite frankly I've hated freelancer ever since you acquired vworker.

I had so many "points" from my rac account usage I could buy time to skype call the freelancer CEO - so I did - and it was never fulfilled, even after me trying to contact support about it multiple times.

The gamification angle? please it just gets in the way (although the new site design it's less obnoxious)

The quality of freelancers is garbage and freelancer.com just doesn't have the same level of targeting rac/vworker had to weed out the useless people.

Sorry for such a negative post, I could say worse, but it's just been very painful experience for me ever since that acquisition. To the point where I barely post jobs anymore and find alternate ways to hire.
So in "Super Planet Crash" the planets can't actually collide? I pumped 11 super-Earths into essentially the same orbit (in the habitable zone), and they seemed to just overlap and do just fine. When I lose, it's always because a planet flies off.
Inflation itself is a tax on holding currency or currency-denominated assets, and that's certainly an important point. The combination of inflation and a capital gains tax would seem to produce an implicit tax on wealth in general, right?

2048D: winning two 2048 at the same time
As stated above, it really depends on a number of factors whether renting is cheaper or more expensive than buying.

You are right that the US has two things to advantage owning: (1) mortgage interest tax deduction and (2) 30-year mortgage terms.

If you're lucky enough to lock in a mortgage rate of ~3%, when you add in the mortgage interest tax deduction, you're practically paying nothing for the money you are borrowing.

However, all it takes is a 10%+ drop in the market when you are selling to wipe out any advantage to owning and often you'll come out behind of someone who rents.
It could be just my perception but it seems like the authors of Heartbleed exploit code are focusing on www and email servers.

- but also building momentum by starting on smaller tasks

- sometimes and for some people and some tasks hacks like pomodoro (basically: the next 25 minutes I will not do anything but this particular thing I have decided. Then and only then I will stop and decide what to do next.)

>Wastes space? In an age where we stream gigabyte movies? Do we need to remind the author that we're no longer in 1982 and that we have evolved beyond floppy disks?

Well, he probably also knows that we now increasingly use SSD disks for our laptops, that are more expensive and sold in lower capacities than HDs on average.

Or that we also listen to music on mobile phones, with like 16 or 32 GB or space (which we also want for apps, photos, videos and other stuff).

Or that we might have "evolved beyond floppy disks" but we have also evolved beyond having 20-100 albums in our collection. In fact digital music collections of 1000 or 10.000 albums are not uncommon.

Now, 1000 albums of 500MB each would make it 500GB for an music lover's collection. That's a non starter in 99% of modern laptops, and impossible on an mobile phone.

I'd rather have it compressed more or in less than 24bits, and fit more stuff to have with me to listen.

(Also keep in mind that music lover is not the same as audiophile).
What if the technology sector was exempt, but rent seeking was taxed 99%
It's not quite perpetual motion, the energy would come from the sun. Start with organic material, use pyrolysis to produce biochar, which you work into soil, along with flammable gases (which Cool Planet wants to turn into liquid fuel). Here's someone else describing the basic concept: http://biocharfarms.org/biochar_production_energy/

The problem is that it won't produce near as much fuel as Cool Planet claims. According to the article, it turns out a lot of big technology investors don't actually consult engineers during due diligence.
Wow, this is awesome. I've been looking for a cheap microscope to just have around the house and noticed that they indeed haven't changed a lot in cost/features in quite some time.
What do you call exploiting?
Even in the absence of property taxes, utility and maintenance costs (and changing market rates for required labor and materials that drive those) would pose the same risk. Property taxes are hardly the only required expenses that might go up when owning a house (and, in CA, have strict constitutional limits on increases, unlike most other necessary expenses.)

Make sure you clearly label the edited version as such (perhaps add a "revisions" section at the bottom listing each version and the changes between them like:

2014-04-14 @12:34: Original publication

2014-04-14 @17:00: Spelling and grammar fixes

2014-04-15 @13:00: Updated wording to avoid terms
potentially seen as insulting

... ... ...

Better yet, include the earlier versions and link to them in that change log. This way you are improving the article yet there is no way (unless you deliberately skip bits in the changelog) people can legitimately accuse you of trying to brush things under the carpet (because everything you edited out to improve things is still there for all to see (and find easily) should they care).

Also make sure you add a message indicating "this is an older version of the article, see link for the latest revision" to the old versions so people coming in to the wrong place from a search result know where best to go.

From previous discussion, quoting 'jbk'

VLC allows amplification of the INPUT above the sound that was decoded. This is just like replay gain, broken codecs, badly recorded files or post-amplification and can lead to saturation.
... snip ...
At worse, this will reduce the dynamics and saturate a lot, but this is not going to break your hardware.

Except it can - because the saturation skews the power distribution towards higher frequencies which weren't designed for. This is very, very well known - it's the reason why one always chooses an amplifier with higher output rating than the speakers, often by a factor of two. It's counter-intuitive but driving a low-rated amp into saturation can overheat and destroy tweeters. (Guitar amps get away with it by having massive voice coils on a speaker which will only ever need to reproduce up to about 5kHz.)
Reading this, I'm pretty sure I can apply it to adult contexts too. Think about all the cases in organisations where 'values' are touted but the behaviour of people tells you how you really get ahead. Everything here is useful if you care about the organisational culture you want to create.
Would you be happier if we called files "objects" instead? It's just a name given to a on-disk data structure. Call it what you will. In the end it is just a stream of bits.

However I agree with you at a higher level. Our computer "file" systems have not evolved. And now they are being displaced by hundreds of isolated apps the manage out content. e.g. You might own the Jungle Book in your Nook account, but your copy of Peter Pan is on Amazon. Worse still, you don't even own these books anymore, they are instead a lease, which can be revoked at any time.

This is a cute story, but it lacks all sources, and it contradicts Wikipedia [1] [2]:

> Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, but this is an invention of the 13th century scholar Johannes de Sacrobosco. Sextilis in fact had 31 days before it was renamed, and it was not chosen for its length (see Julian calendar). According to a senatus consultum quoted by Macrobius, Sextilis was renamed to honor Augustus because several of the most significant events in his rise to power, culminating in the fall of Alexandria, fell in that month.

The fact that February has the fewest days makes sense considering it was the last month of the Julian year (March was the first, hence July and August were called quintilis and sextilis, for fifth and sixth, respectively). It doesn't quite explain why the 31-day months are distributed unevenly over the year, but if you are going to take days off, it makes sense to take them off the last month of the year.
