vhf | 12 years ago | on: A list of free programming books

README.md says : " This list initially was a clone of stackoverflow - List of freely available programming books by George Stocker. Now updated, with dead links gone (hopefully) and new content. "

I've had this SO list in my bookmarks for long enough, and there were more and more dead links in it. I felt the need to move it to github in order to keep it up-to-date and to augment it.

I apologize if the intention or original source were not made clear.

> Drag and drop is universally a "cut and paste" operation.

Unless you are using Gnome and the origin and destination of your drag and drop are on two different devices. In which case it will copy instead of cut.

vhf | 12 years ago | on: I do not speak English, what better way to ask in English?

I don't think it's unethical, but I do think it's kind of rude.

If you're looking for idioms, give bab.la a try : http://en.bab.la/dictionary/english-portuguese/

If you're looking to learn/improve your English, take a look at Duolingo : http://www.duolingo.com/ -- it even supports Brazilian Portuguese.

If you really want to understand the links posted on HN and contribute to the discussion, learning some English is obviously the way to go. Make the effort, it's well worth it !

Good luck

(I'm not a native english speaker. I learned by watching US TV series with english subtitles, pausing the video every single word I did not know to look it up on wordreference.com. I eventually didn't need the subtitles anymore.)

vhf | 12 years ago | on: Show HN: How I Wish Scientific Papers Were Displayed

Contrast[1] is too low for me as well, and text should not be justified[2] IMO.

I too appreciate your effort, but keep in mind the differences between print- and web- layout design. Most scientific papers are published in PDF, using Latex. These two work great for the print. Correct hyphenation, good justified text, etc. Browsers are not that far yet, unfortunately.

vhf | 12 years ago | on: Ask HN: Your opinion of Bootstrap

Bootstrap's initial intention was both not to lose time with webdesign when building back office applications and to have a consistant design in back office applications.

This is the reason why I think it's a great tool for any back office need, but not so great for front.

To me, Bootstrap feels like it's supposed to be used as-is. I love Bootstrap, it saves be a lot of time. But when I need a framework for front, I much prefer Foundation, which was meant to facilitate designing websites for Zurb's clients.

Nope. Zerocoin is.

(Disclaimer : I'm a fervent Bitcoin supporter, I like its pseudonymous property and discard any anonymat claims. I've never used zerocoin because I don't have any use for it.)

Well, thank you, I know how bitcoin works. :)

The blockchain does not store any IP address. Read about the protocol or read the specs or read the code, or easier : ask anybody.

Bitcoin is absolutely not anonymous, and not intended to be anonymous. Which does not mean that the IP address of the sender and/or receiver is stored into the blockchain. The blockchain contains txid, amount, addresses and timestamps, but no IP address.

To examplify what bitcoin.org says in your quote : If you open an account on anybitcoinstoreorwalletorexchange.com, which assigns you a deposit address or which allows you to withdraw bitcoin to one of your bitcoin address, then this website will obviously be able to match your bitcoin address to the IP you used to visit the website, which might not be in your best interest depending on the website intention. Therefore, you could use Tor. That is all.

To the point of "a new one each time you receive money", it would be better phrased as "each time you receive money from a new untrusted peer". Let's say I got an account on example.com, and want to withdraw bitcoin from this website for the first time. It is considered best practice to create a new address to receive these bitcoin. Then whenever I want to withdraw from this website again, I could use the same address. This is the reason why bitcoin addresses can be labeled in the bitcoin software. Think of the tuple (sender_address, receiver_address) as a private key for a specific transaction funnel.

> mask my IP to keep my actual IP from occurring in the blockchain.

The blockchain does not store any IP address.

> Needing to "create a new bitcoin address" for every transaction, also fishy.

Creating a new bitcoin address for every transaction is not recommended and not needed. So no, it's not fishy. On the contrary, having the possibility to generate different address and using one address for one addressee is quite smart and useful.

vhf | 12 years ago | on: Poll: "Giff" or "Jif"?

> QT should be pronounced "cute", but I say "queue-tee".

I think we would say "queue-tee" if it was QT instead of Qt. To me, "cute" makes more sense for "Qt".

vhf | 13 years ago | on: Django Unchained – Introduction to Python and Django

I didn't get it when Google decided to name their language Go because it was awfully hard to google. Same here : the name isn't bad but will be impossible to google for anyone forgetting to add "python" to their request.

Anyway, great initiative, I'm looking forward to read it ! (star or bookmark it if you intend to find it next week) :)
