Bike messengers are almost universally contractors (there are some wonderful companies who basically exist to treat their messengers well, but they're a small part of the market). That obviously means they don't provide insurance and don't have to carry workman's comp for those employees. Most messengers I know make dirt pay and could never afford insurance except through their spouses (or parents if they're young). They live and die on being careful and help from the community and the BMEF (which is an awesome organization), and they do it because they can barely imagine life off a bike even in the face of the risks. So Uber isn't unique in this sense at all. That said, they're obviously swinging to cut margins out of an industry that already can barely support its workers. I'm more curious about the rates they pay than anything -- I actually suspect few in the industry would object to outcompeting large dispatchers if they pass some of that on to messengers in the form of better/stable pay. But BMEF donations "with the launch" (they do not say long-term) are no substitute for responsible employment.

On the whole I'm a bit surprised -- the messenger industry has been shrinking a lot as people need fewer actual signatures on documents. I suspect they're doing it more to understand the delivery market and pilot a delivery service than for the traditional document carrying market.
I would stockpile parts for the machines and take them off the network. If you have enough spares and your computers aren't exposed to outside attacks, I don't see why they couldn't hum along for another decade or two.

In Python 3.4's pathlib, you can concatenate two paths by dividing one path with the other.

I guess you could torture @ for similar purposes in an email library or something.
But that's the catch: I am not convinced AV vendors have the resources, the complete knowledge and the access to Windows inner workings to fill in MS role.

And what about the legal rights ? Would they be allowed to patch a security kernel breach, or a lib, made up of closed proprietary code in binary format (an extreme and unlikely case but that's what I read when IT people tell users "we'll just use an anti-virus to circumvent the lack of MS updates") ?
It was smooth for me and matches the reference rendering. Maybe your machine is under powered (Netbook or something?)?
So this price is so cheap, I've never seen anything like it. As in, about 1/10 the price of the competition.

It doesn't look like the owners have shown up here yet. If they do, here are some (hopefully helpful) suggestions from a target user who purchases proto pcbs all the time over the internet:

> Examples: 4cm by 2cm, red PCB: $12 for 10 copies - This should go on the front page. The price is so low that I thought it might be $12 per copy, but you have to order 10.

> Return customers - You like it dirty, you're back for more - Ok, for $12, I guess I can put up with this kind of stuff. But you're not helping yourself here.

> Is my design safe? - Your board will go to a cut-rate prototype PCB factory in China. In all likelihood they have too much volume to give a crap about what's on your PCB, but if this is a concern PLEASE FIND ANOTHER SUPPLIER. - Well, this one is actually funny, but in a sad, tearful sort of way. Why remind people of sad truths? All it can do is take away what could have been a potential customer.

> Shipping is by Hong Kong Post (or similar), which takes 4-30 days - This is great for a lot of people, but there are a whole class of other people (maybe 50% of your audience) who would gladly pay quite a bit more money to get something faster. 30 days is a long time. A different shipping option, even if it was $35 or so, would go a long way here.

But patients shouldn't expect that the stimulator will help them walk -- at least not now and maybe not ever.

It's nice to see a mainstream media outlet report on a significant medical advance without the hype. This result should create a lot of optimism, but not without caution.
Actually, the legality is unproven. There's still information being passed from the person served with the warrant and the person being spied on.
Maybe my TCS background and dabbling in mechanism design has biased me, but it seems to be that truthfulness is a desirable property from the perspective of society: It would be beneficial to have a system that is designed in a way that allows participants to state their intentions and desires truthfully, without any incentive to lie.

Auction theory is all about achieving that for simple, single round auctions. Why not redesign the stock market in a similar way as well? I suppose it could make for a nice PhD thesis (or several).
You could attempt to move to a VM, this'll likely fail. I know a KVM environment should work theoretically but it may not.

If that fails you'll likely need to go with an air gap. Transfer all data in and out via flash drive and run nightly virus scans on host computer and the XP one. If you can't air gap the XP computer. Nightly virus/mal scans, allocate more time for IT preemptively, and maybe prayer?

Weekly/Monthly hard drive images are likely a good idea also.

:.:.:

Also stock pile old hardware for it. Trying keeping a few functional ATA hard drives on hand, spare PCI cards if you need them. In all honesty have 1 or 2 computers that can serve as drop in replacements on failure is likely a good idea.

A 4 or 6 layer option would be excellent. The design rules have been improving at the batch PCB order houses, I remember when 10mil was a nice feature. I think a good 4+ layer option is only a matter of time. 100% e-test is great as well.
No, they're using the term correctly. The plausible deniability in OTR comes as a result of forward security. Since past and future traffic can't be decrypted with a certain captured key, the entity that captures that key can't cryptographically tie an identity to the previous messages.
It's not dead. I work for a large health organization (100,000+ employees) and IE6 is still the default browser. Users can manually update.

Lastpass appears to use TLS 1.2 with Forward Secrecy. They would have to hijack individual sessions (or somehow get the current session kays and capture the data at the same time).
I can assure you that it will be maintained. John and I are committed to this project and have been working on it full time, and will continue to do so.
It doesn't use mmap for locking though - and in any case one database is already multiple files (2GB max). There are internal data structures used by MongoDB and the database itself takes care of locking, mmap just gets the data into memory.

Whoa, this looks pretty fantastic to me. Have you thought about integrating with Shopify? It has a lot of trouble with recurring payments, and Chargify is a pain to use and adds an additional $60/month charge on top of the Shopify fees (it is still worth it, but Shopify having simpler recurring payments would be amazing). This looks like exactly what I was looking for about a year ago when I add recurring payments to my store.

EDIT: After signing up, I see integrating with Shopify isn't even necessary. Do you plan to compete with them? Or potentially be a feature to work with them?

Good questions. Snappy Checkout is not a shopping cart. It'll only work in situations where a purchase involves buying a single product (e.g. an eBook).

Reviews, pictures, etc. are things that fall outside of the scope of Snappy Checkout.
It's great, the functionality is good and the price is fair.

I could only see USD hardcoded as the currency, though, and there is the old euro VAT problem -- businesses in Europe need to be able to charge customers VAT depending on where the goods will be delivered and what type of goods they are. It's all pretty complicated stuff, but without it a checkout system is useless to most Europeans :(

It has always seemed to me that anyone who can build a checkout that handles VAT properly would have the whole of Europe beating a path to their door.

They say it's because the updates make the OS less secure. So they are all going to disable Win XP because of vulnerabilities.

PS. They also don't support linux
I don't have numbers, but I'd be willing to guess that a fair number of IE6, 7, and 8 users were on corporate PCs which prohibited installations of newer versions of IE or other browsers. Microsoft can't do anything about those people! They have been try to end support for Windows XP and IE 6 for years, and newer versions of IE auto-update unless the user specifically tells the OS not to.

No, the notion of the unbreakable one time pad is a great notion to have around.

It is the good standard for crypto systems. Yes it's unworkable in practice but that's exactly why nobody really uses it. It is useful for teaching and making comparisons.
Resize Bulk Photos at once with Fotosizer
I would like to read an actual in-depth comparison. While undeniably the quality of the Ruby implementation has a long way to go, Ruby has very "loose" semantics and I think some of the optimizations that are possible for Java, JavaScript or even for Smalltalk are simply not possible for Ruby because you have less assumptions to rely upon, everything has to be looked up at runtime basically.

Besides just nitty-gritty optimizations there are some high level design issues which are interesting. JVM performance is great for languages like Java, but for some reason probably related to the JVM all Java web servers seem to be multi-threaded monsters, which turns debugging into a mess and seems to make DoS attacks way easier. We use a self-hosted Jira on top of Tomcat at work, there are maybe 30 simultaneous users and every time one of them does something computationally expensive or uses some buggy functionality the whole process goes nuts, memory leaks until exhaustion, load goes to maximum etc., the whole web sever has to be restarted. With a web server with multiple worker processes you just restart the single worker and call it a day. Does anyone happen to know why the worker-based hosting model with separate worker processes seems to be completely absent from the Java world in favour of multi-threaded servers?

No, this is a a breifcase full of one time pad. If you could fit 32 4 TB hard drives full of pad in the brief case that would allow you to send 128 TB in the future securely using something like an XOR one time pad. Assuming you are just sending ASCII and compress it before sending/XORing you could send a lot more then 128 TB of ASCII.

This is pretty powerful. It means that organization which and periodically move physical assets securely can send information in a manner that is secure even if quantum computers reach their full potential.
Ah, that makes a lot of sense. Thanks for that image. Until now I had assumed it was a coil that hurled a solid metal core (which always had me wondering where the rail part of the name came from). No idea how I failed to catch that for years.

Hmmm. This sounds a little too good to be true. My gut feel is that they are looking to get a peek at your source code, and they'll want that before they give you any money. Keep in mind what PG says about deals, assume that it's not going to happen and just keep doing what you're doing.

That said, this is a great, low cost way to experiment with this type of interaction. If I were you, I'd set some strict goals as if it's a genuine offer (e.g. minimum sale price, not showing any source code pre-receiving money, etc), and then see how it plays out.

I've been in similar situations to yours before, and It's been really valuable to learn and make mistakes at small scale. As soon as it becomes a pain and your not getting much out of the experience, just finish it up on your own terms. The important part being that you should know what you want if it was real, and what you want out of the experience. Then either way you have nothing to lose.
They could do so, but non technical people don't even know what that is :)
While MongoDB has many use cases, it's just perfect if you need to pass over JSON to your JavaScript. Or need JSON output for any other reason.

It depends on your own goals. If you plan to maintain and market it then keep it.

I personally like building things, and starting things, but I am much less interested in marketing and making a business out of it. I would sell out in a minute and move on to the next project. I am not likely to worry about what it could have been later down the road or to get upset if I could have gotten more for it later.
And laws were changed to make the crimes much easier to prosecute and much more severe.

For the typical $5/mo SaaS subscription

This is the problem. Typical Saas subscriptions are significantly more than $5/month, at least if you want to stay in business. $50/month (as a starting tier) is more normal and could actually be sustainable.

If you're charging only $5/month for your SaaS, then you will be unlikely to have enough margins to pay for any external services (and possibly your rent).

For reference, Gumroad charges .30 + 5%. So on a $50/month subscription that's going to be $2.80, whereas with Snappy Checkout its only going to be $1.95. More importantly, as you charge more (e.g., $200/month), the gap would widen even further.

We currently process about $3k/month through Gumroad and e-Junkie, so we're just about at the point where it makes sense to look at other options. If we can move to something like this as opposed to rolling our own, I'm very interested.
This is something I have been trying to find the time to do.

Something like this is great to learn how the JVM actually works, and can improve the way you code Java. I always found it incredibly boring to read language/vm specs but building something like this makes the abstract and obscure, concrete (at least for a programmer's brain)
Ach! I let myself get drawn into a semantic argument, and it earned me my first downvotes!

My only point was that talking about one-time-pads as "unbreakable" encryption is not a useful discussion, since "unbreakable" and "encryption" need to be better defined.

If we expand the definition of "encryption scheme" sufficiently to allow transmission of secrets outside of cryptographic channels, then OTP is not even close to the only unbreakable system.

Only by explicitly defining attack vectors can we really get a good framework for reasoning about cryptography, and even then we know that we can prove an encryption technique is bad. For "goodness", all we can do is increase our confidence, until the day the confidence drops to 0.

Anyway, with this last salvo, I'll retreat from this conversation; it's pretty clear to me that my inane ramblings about semantics are as annoying to the community here as they are to me when other people make them.
Governments use it all the time. (Men with handcuffed briefcases and armed guards..)

Before you send your submarine to sea for example, you can provide them with many gigabytes of one time pad. They can then use this for their most secret communication.
Holy shit. I'm ian, I did this. This was an inside joke and a weekend hackathon, never meant to be public. We will ship orders but it really is a joke. I mean... you like it dirty and you're back for more... where are my damn pcbs? I thought it was obvious lol. All the backend is there and boards are proper, we have a logistics company, but its really just a joke that went too far.

>I would argue that almost every single linear algebra routine can be interpreted in some form as a matrix-matrix or matrix-vector multiplication.

It's not really necessary to argue. Cayley's theorem guarantees that every group is a subgroup of a symmetric group:

http://en.wikipedia.org/wiki/Cayley's_theorem

A symmetric group is then a subgroup of the general linear group in any field, where the general linear group GL(K, N) is the set of invertible NxN matrices with entries from a "field" (just think "numbers") and therefore any [finitely generated] group is isomorphic to a group of matrices under matrix multiplication; this is the underlying concept of representation theory.

If we back up a little, a group is a very general sort of algebraic structure; many important concepts have an underlying group structure, such as rotations, permutations, and any sort of reversible computation. This latter case implies that matrix multiplication is Turing complete; the simplest such set of matrices is generated by the Toffoli gate matrix. The relationship of groups to geometry is due to the underlying correspondence between the axioms of a group and those of geometrical transformations. A set of reversible geometric transformations includes an identity element -- do nothing -- and obeys associativity (sorta complicated, but it makes sense if you think about it) and inverse operations (by assumption): this makes it a group, and it can be represented by matrices. If we remove "reversible", we get exceptions -- like the cross product -- but these are usually related to groups (cross product -> quaternion algebra).

So matrix multiplication is actually really, really fundamental in a lot of mathematics. It's also a special case of tensor contraction, which could justify another tower post (but won't).

>And trust me, when you are writing numerical code, being able to read the mathematical formula clearly is essential, especially when you have a lot of formulas and need to figure out why your code is giving you numerical non-sense.

Never sell to your first offer...unless its to google. If 1 person wants it, there's a very good chance 2 people want it. And if 2 people want it, they are willing to bid on it. Wait for at least a second offer. It will give your project time to grow.
Exactly, men with guns secure the one time pad. The data sent using that pad is secure.

Nit: I would consider one time pad to be a method of encryption.
