It'd be strange if Oracle, IBM and Microsoft didn't offer any certifications for their database products. Although I suppose they tend to be more about the management side of them and not the querying stuff.

I assume the HR drone had no idea what to post so that's what ended up there. SQL wasn't even designed as a programming language (and it's not) to be used by developers or engineers. It was supposed to be used by users and ops people to query their databases. In other words, it's very easy and you should have no trouble picking it up very quickly. SQL has a standardized set of instructions but every implementation (MSSQL, MySQL, PostgreSQL, etc.) has its own implementation quirks and additional/modified functionality so you may want to learn about more about specifically what back-end you'd be dealing with if looking at a particular job.

Jo posted:I'm considering Scala, since it seems to fit the bill, and it's Java base means I can use Swing for GUI if I have to. Haskell is a potential candidate, even if the syntax is a bit scary. Are there other languages worth considering? I'm a total Common Lisp zealot myself, so I'd suggest that except the GUI support has always been flaky. With Quicklisp it's a breeze to try out libraries. Compared to the languages you already worked with the community is quite a bit smaller so getting help is a little harder but there's a Lisp thread here on SA. Clojure would check more of your boxes except it isn't turtles (Lisp) all the way down. Anyway, Lisp is interesting enough to at least try out even if you do not end up liking it. Maybe just installing Racket and working through The Little Schemer would be a good introduction. Personally, I stopped looking for "the best" language once I discovered Common Lisp. It's the language that gets the least in my way and Lisp is so loving malleable / fluid, I find it a joy to work with. Other people can't stand it however. Like I said, it is an interesting enough family of languages to at least have played around with. aerique fucked around with this message at 09:06 on May 12, 2013 |

I didn't see a C# or Windows development thread, and I'm not sure this question necessitates one, so I'll start by posting it here... I'm a web developer. I work on a team of web developers. Until a couple months ago, I had never developed a desktop application, and was unfamiliar with C#. My employer tasked me with using Visual Studio Tools for Office to create an Excel add-in, with the understanding that there's not a single person at this company that knows anything about this technology stack. Somehow I muddled my way through it, and now I've got a usable application. The deliverable timeline over the past few months has been pretty tight. I've spent all of it learning about VSTO, and that has prevented me from learning some fundamental things about C#/Windows development, such as: 1) How to write effective tests within Visual Studio 2) How to write effective tests for a VSTO add-in 3) How to encapsulate code within reusable libraries, and how to include them in my solution My question: Does anyone know of a book or tutorial that covers these things and is less than a thousand pages long? I've been searching, but much of what I'm finding is specific to various third-party add-ins that I have no intention of purchasing.

Usually, when I want to learn a new language, I spend 5-10 min on a syntax overview and then jump into writing something like a little web app or small game with it and look up things as I go. This will not work with one of these languages.

Azuth0667 posted:All of the postings I've been looking at ask for certification so I guess that level of skills. I'm not really sure where to start here. SQL complexity ranges from the basic query statement like SELECT * FROM MyTableName which says to retrieve (SELECT) everything (*) FROM the table called MyTableName to much, much more complex queries that call data from specific columns in different tables, manipulate that data, concatenate, collate, create hash values, views, functions, stored procedures, and on and on. I only know MS SQL Server so I'm not sure what advanced things Oracle can do, but it's a lot as well. The Structured Query Language (SQL) itself has a base set of functionality that the major companies like MS and Oracle mostly adhere to, but there are some key differences in syntax and functionality at the advanced level that each has that the other doesn't or does differently to achieve the same result. Best thing is to pick a SQL variant like MS SQL Server or Oracle (the big 2) and learn that. If it's a large company and they are using MySQL in their production environment, run, run like hell!

I believe there's a windows version of this now as well, but I've never used it and have no idea how well it works. And yeah, X forwarding only applies to stuff already on the school machine - it's a way of running programs on a remote system and displaying them on the system you're actually using.

I'm an undergrad majoring in CS. Right now I've finished taking the core courses that teach the methodology of programming, as well as data structures and some stuff that's a little more in depth like reading assembly language. I'm interested in spending my summer doing some studying on my own. I'm especially interested in computer security and want to learn how programs are exploited/defended against exploits. Can anyone point me towards a book or another resource that I can use for this?

I found that the quickest way of getting up to speed on security is to just go to a bunch of conventions - check out say, Summercon (http://www.summercon.org) or Defcon (http://www.defcon.org). Conventions will generally have student discounts. You might not really understand the subject material presented but I learned a poo poo-ton just by googling stuff I heard people talking about at Summercon. The problem with learning from books is that computer security is a rapidly changing field and the textbook stuff will be super out-of-date.

Check out OWASP. WebGoat is a cool way to learn about web app penetration testing. There's a cool book on reverse-engineering mobile called Decompiling Android which would be interesting too (mobile security is huge right now and it would be fun to get in on it early). Some good books which I think lead to further thought/study: - Software Security by Gary McGraw - Writing Secure Code - The Web Application Hacker's Handbook I think one of the most important thing is to recognize that security goes well beyond network security (at my school, our only security class is about crypto and network stuff) and also that people focus too much on penetration testing instead of just writing good software to begin with. OWASP is definitely a good way to get your feet wet and get a broad overview of the landscape. SummerCon sounds awesome though. I'm in NYC this summer so I think I'll definitely try and go.

I'm a tree stump when it comes to advanced programming know-how, so please excuse me if this question is supposed to be a simple one, but it's been on my mind lately and this seems like an interesting place to get an answer. How do programs update? More specifically, when an update is pushed out, how does it usually bring two different prior versions of software to the exact same up-to-date version? I guess what I'm asking is if I have version 1.01 of a piece of software, and someone else has version 1.5, how come some software will update both of our version to the new one (let's say 1.6) without having us download every single update on the way chronologically? And more importantly, how would they do it without the update file having a file-size equivalent to all the intermediate versions (since it needs to know exactly which addresses need to be updated)?

If you're doing internet updates you can just create patches that target specific versions and update directly to the latest (or to a common version) since you don't need to rely on people knowing what version they're on currently (though it's obviously more work doing it this way). quote:how would they do it without the update file having a file-size equivalent to all the intermediate versions (since it needs to know exactly which addresses need to be updated)?

It's pretty rare to have software actually use binary patches. Usually executable files are just replaced outright, so both the 1.01 user and 1.5 user is given the same 1.6 executable. Similar for other types of code. In fact, most often an "update" is simply the full installation for the latest version, with some code in the installer to handle any special cases of updating configuration or such. Things like OS updates tend to work with component packages that are updated individually. Meanwhile, large games (typically MMOs) have simple code updates and then have a data file system where they can either add on more data files that override earlier versions, or a system where it repacks the old data files installed. The latter (repacking) takes more time to update and needs a lot of scratch space during the update, but in the end gives lower installed footprint and better loading performance.

There are a lot of problems with MySQL, some historical and some current, with regards to data integrity and basic database features (eg. the lack of foreign keys, mysql_real_escape_string(), etc) that have indeed given it a poo poo reputation when used as anything more than a glorified flat file (how rails used it, historically) or as "the little hash table that could" (how PHP used it, historically). Some of these have been fixed or ameliorated. The "community" that grew up around it is also bad.

Why did MySQl get popular? Because it was there at the right time and provided what people needed, so it got deployed *everywhere*. Why is MySQL going nowhere? A couple of reasons:
New projects should use PostgreSQL.

"[s posted:shrughes[/s], Thanks for the info - I had no idea. 1) Are there still people who disagree, and advocate for MySQL, or is this just a decided issue in database circles? 2) Is Postgres awesome, or does it just not suck as badly as MySQL? Are there cliques of people who have valid, fundamental complaints about it, as well? 3) My impression is that MySQL is considered more standard, and is more supported. For example, FileMaker can connect to a MySQL external data source, but I don't think it can connect to Postgres. Is this a pretty wide problem? If so, is it changing? 4) Is either one easier for IT departments to administer? 5) It seems to me that everyone hates Oracle, but not for basic integrity problems as much as for business practices, costs, and for being a corporate bully. I think we have access to an Oracle license. Given the choice, would using Oracle be preferable to using MySQL? We're at a bit of a fork in the road at work in terms of where our projects are going, and if I can save myself some grief later by advocating for better decisions now, I'd like to do so, but I need to know what I'm talking about, and I'll need to have viable alternatives.

If you asked me to expand on that, I would have a hard time distilling my thoughts, though. 1) MongoDB is a joke too and people still use it - can't really say anything about the database programs is "decided" unless it's already dead and buried. Don't worry about it too much IMO. 2) Postgres is pretty awesome. That said, iirc MySQL does multi-master replication; vanilla Postgres doesn't. 3) Depends on what you mean by standard. Widely used enough to get a lot of support? Prefers incorrect behavior to throwing errors? 4) phpMyAdmin is one of the most entrenched MySQL admin interfaces. Sequel Pro (mac app) is also pretty solid, and both are built for MySQL. 5) If you have a license for Oracle? As far as technical concerns go, Oracle over MySQL, every time. There's a reason Oracle continues to sell it for stupid huge amounts of money.

If there wasn't a strong case they'd want to be in a position of trust rather than upsell you, fail, and have you go to a db they didn't own. No surprise that they'd recommend MySQL if their consultants thought Oracle wouldn't be a good fit.

I'd love to start doing some PHP work and design sites for small local businesses, but I'm afraid of potential legal repercussions and stuff. Also tax implications for when I need to file next year...
