Enough With the Salts: Updates on Secure Password Schemes - Blog - Matasano Security
When it comes to password storage, you’re much better off using a well tested and reviewed system than writing your own. You’ll want that to be something purpose built, rather than relying on fast cryptographic hashes which are especially susceptible to fast guessing and hardware optimization. This means you’ll want to use scrypt, bcrypt, or PBKDF2 (in my order of preference) with an appropriate work factor. If you’re stuck deciding between scrypt and bcrypt, you can pretty much flip a coin and end up with something reasonable.

A JUSTIÇA DECIDIU: compras internacionais abaixo de 100 Dólares NÃO PODEM ser tributadas! | Blog do Jotacê
Caso você seja tributado em uma compra internacional cujo valor seja abaixo de US$ 100, a recomendação é entrar com um pedido de revisão. O site disponibiliza dois modelos de carta (arquivos DOCX), um para compras abaixo de US$ 50 e outro para compras abaixo de US$ 100. Esses documentos devem ser preenchidos e entregues à Receita Federal para que o valor de tributação pago seja reembolsado.

Caso isso não aconteça, a solução é entrar com uma ação no Juizado Especial Federal. Como o valor da causa a inferior a 20 salários mínimos, não é necessária a presença de um advogado. Para entrar com uma ação, é necessário preencher o modelo de documento (arquivo DOCX) que pode ser baixado neste link.

Encryption Works: How to Protect Your Privacy in the Age of NSA Surveillance | Freedom of the Press Foundation
The stories of how NSA whistleblower Edward Snowden first contacted journalists Glenn Greenwald and Laura Poitras (both Freedom of the Press Foundation board members), and how he communicated with the Washington Post's Barton Gellman, have given the public a rare window into digital security and conversing online in the age of mass surveillance.

In response, we've just published our first whitepaper—using the public comments by both Snowden and the journalists involved as illustrations—to show how reporters, whistleblowers, and ordinary Internet users can still protect their privacy online.

Best Practices for Designing a Pragmatic RESTful API | Vinay Sahni
Now, the internet has no shortage on opinions on API design. But, since there's no one widely adopted standard that works in all cases, you're left with a bunch of choices: What formats should you accept? How should you authenticate? Should your API be versioned?

In designing an API for SupportFu (Customer support software for SaaS & eCommerce), I've tried to come up with pragmatic answers to these questions. My goal is for the SupportFu API to be easy to use, easy to adopt and flexible enough to dogfood for our own user interfaces.

O que o Código de Trânsito diz sobre bicicletas e ciclistas
Ao contrário do que muita gente acredita, o texto do Código Brasileiro de Trânsito valoriza essencialmente a vida, não o fluxo de veículos. Na redação de seus artigos, percebe-se uma preocupação acima de tudo com a integridade física dos diversos atores do tráfego, sejam eles motoristas, motociclistas, ciclistas ou pedestres.

Bicicletas, triciclos, handbikes e outras variações são todos considerados veículos, com direito de circulação pelas ruas e prioridade sobre os automotores. Portanto, quando falarmos em bicicletas neste artigo, considere que podem também ser “ciclos” de outra natureza.

Veja abaixo todos os artigos que se referem a esses meios de transporte.

When upgrading the version of Rails used in an application, it can be difficult to know precisely every detail that should be changed.

So, to that end, I've generated applications for each version of Rails; and, for each version, I've generated a diff between it and all versions before it. You can use these diffs to know precisely every change needed to upgrade to any version of Rails.

maxgillett/s3_multipart · GitHub
The S3 Multipart gem brings direct multipart uploading to S3 to Rails. Data is piped from the client straight to Amazon S3 and a server-side callback is run when the upload is complete.

Multipart uploading allows files to be split into many chunks and uploaded in parallel or succession (or both). This can result in dramatically increased upload speeds for the client and allows for the pausing and resuming of uploads. For a more complete overview of multipart uploading as it applies to S3, see the documentation here. Read more about the philosophy behind the gem on the Bitcast blog.

Large Ruby File Downloads Done Right! - Ruby on Rails with Dan Watson
I have recently been writing a utility in ruby to move some very large files across from Rackspace’s Cloud to Amazon S3. Basically the utility firstly downloads a file from Rackspace and then uploads it to S3. Well this all seems very straight forwards but there are considerations that have to be made when you download large files using any scripted utility.

But we've been using the Retina MacBook Pro a little more since our review published a couple of weeks ago, and have discovered that the massive 95Whr battery is actually capable of lasting at least 8 hours or more. To achieve this, we overrode Apple's automatic graphics switching using the donation-ware app gfxCardStatus to force OS X to rely solely on Intel's integrated HD4000 GPU.

Ian McAllister's answer to What is Amazon's approach to product development and product management? - Quora
There is an approach called "working backwards" that is widely used at Amazon. We try to work backwards from the customer, rather than starting with an idea for a product and trying to bolt customers onto it. For new initiatives a product manager typically starts by writing an internal press release announcing the finished product.

Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery; Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss; Keep your battery in cooler temperatures. Hot hot heat is not good for it; If you're gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).

The 1140px CSS Grid System/Framework · Fluid down to mobile
The 1140 grid fits perfectly into a 1280 monitor. On smaller monitors it becomes fluid and adapts to the width of the browser. Beyond a certain point it uses media queries to serve up a mobile version, which essentially stacks all the columns on top of each other so the flow of information still makes sense. Scrap 1024! Design once at 1140 for 1280, and with very little extra work, it will adapt itself to work on just about any monitor, even mobile.
