With passwords, it’s not about creating a password, or anything like that; it’s about keeping passwords safe. Making sure that they’re not compromised while being passed from you to the server, and things like that. Something that’s definitely required, but not something I’d ever considered before. | With passwords, it’s not about creating a password, or anything like that; it’s about keeping passwords safe.

- | Web security is almost a combination of the previous two (encryption and passwords), but it, of course, uses RSA encryption. Like the previous chapters, we’re shown complicated stuff using tables and diagrams. Which is helpful for the more visual learner. | + | Web security is almost a combination of the previous two (encryption and passwords), but it, of course, uses RSA encryption.

+ | Le livre, dont on pourrait traduire le titre comme « Le fonctionnement des logiciels : la magie derrière le cryptage, le CGI, les moteurs de recherche et autres technologies ordinaires », démarre avec des trucs de base sur le cryptage. Il vous montre comment échanger des nombres et des lettres, etc., mais, très rapidement, il explique le cryptage AES et présente le chaînage de blocs chiffrés. | ||
+ | |||
+ | Pour ce qui concerne les mots de passe, le sujet n'est pas leur création ou des trucs comme cela ; il concerne comment vous assurer que les mots de passe restent sûrs et sécurisés et, notamment, ne sont pas compromis pendant que vous les transmettez au serveur. C'est, sans conteste, quelque chose de nécessaire, | ||
+ | |||
+ | La sécurité sur Internet est presque une combinaison de ces deux choses (le cryptage et les mots de passe), mais, bien entendu, elle utilise le chiffrement RSA. Comme dans les chapitres précédents, | ||

Another oddity. Game graphics. Like the preceding chapter, this one does briefly discuss old school pixel stuff, but this is mostly rendering and more modern stuff. | Another oddity. Game graphics.

- | No, you won’t get to see Google’s secret sauce in this chapter on search. This starts focusing on data sorting and the kind of search you’d use in searching for files on your desktop, or within files. But then it does lead into how search engines get their data, and how it’s served up in a manner that gives you the best to worst results. | + | No, you won’t get to see Google’s secret sauce in this chapter on search.

- | Second-to-last chapter is on concurrency. This is how data is quickly stored and retrieved. It’s how data is kept in an order where things don’t get mixed up. | + | Ensuite, vient le CGI des films. J'en étais sidéré, car ce chapitre semble totalement hors de propos. Il traite très brièvement de deux ou trois vieux effets (comme les mattes), mais, pour la plupart, c'est dédié au CGI que nous connaissons tous depuis Jurassic Park. |

Lastly we have map routes. This is one that I hadn’t read about before and was pleasantly surprised to have this chapter. How does your GPS come to a particular route. How can it pick the shortest route (in miles) or the quickest route (in time)? | Lastly we have map routes.

- | This is a great little book with very interesting information. It’s good to know what’s happening in the background when something is encrypting, or you’re doing a Google search. I have to drop a point for jumping to CGI (and, to a lesser extent, game graphics) as, while it is something we see quite often, it’s not something most of us will actually use. If they had to be kept, it might have been better to put them at the end to keep things flowing better. | + | This is a great little book with very interesting information.
