i wish sql natural joins had mainstream support then devs would quit bitching about how much work it is to write a query and dumb devs would start using foreign keys like they already should be also linq does it right and let's you define things in the one true order - tables first then the rest and lastly columns orms are good but you still gotta normalize your tables and i've seen a lot of "code first" projects with absolute poo poo design in the db so i say make your tables, map to them with your orm, and optimize the bottlenecks with raw sql (preferably sprocs imho) tef posted:sql is fine. for some reason, people would rather write queries in chained object notation, translate them to some crack addled sql chained object notation? like Table1.Child1.AllItems(x=>x.Something=='foo')? tef posted:regular expressions in a language? sure true i think lots of sql hate is b/c devs don't like magic strings with potential bugs that aren't caught until runtime. less of an issue if you automate all your testing though i like linq it's expressive but translates pretty much 1:1 to good sql, maybe i should give entity framework the ol' college try it uses linq instead of some awful HQL-alike

orms are an attempt to solve an unsolvable problem. use the most lightweight implementation of activerecord for your language you can find and write your own drat sql for anything complicated. sql is easy, sql that doesn't make the server poo poo its pants under load is less so

There's only 2 rules of sql. Don't grab more than 1000 at a time. Don't do sql "calculus", conversely join only on indexes. Also javascript is a fine language. It has everything you need to write good programs from scratch. The trouble comes in when your base is coming from someone else who probably never wrote a line of any other language in their life. This problem is shared with others, but javascript wades into the domain of Normals much more than the spergier languages. MeruFM fucked around with this message at 00:12 on Jul 24, 2012 |

The best part of SQL is that if you experience significant growth, what once was good SQL becomes bad SQL. It's like a can of spam under a radiator, fine for months but then suddenly rancid. I also nominate dazjw for a medal of honor for that post!

I keep thinking that one of these days there'll be an OOP anti-fad and we can all get that nonsense behind us but nope, 30 years in and here we are. Still, we are at least kinda sorta coming around to the idea that C++ is a Bad Programming Language, so there may be some hope yet.

Eight years later, Luciani has finally landed an interview—and a very public one at that. She is one of four applicants-cum-contestants vying for a blue badge on Be the Next Microsoft Employee, a new reality show that is seeking a SQL Server expert to join Microsoft IT. The first episode premiers today, and the online series will run for the next four weeks. In each episode, contestants face a technical challenge based on Microsoft Certification exams. The winner of the show—and the next Microsoft employee—will be revealed August 21 during the finale. "The concept is more or less 'Top Chef' for geeks," said Mark Protus, senior audience marketing manager for Microsoft Learning and creator of Be the Next. Protus came up with the idea as he pondered ways to show the impact that training and certification can have on a career.

ive been playing about with clojure recently and am wondering about using compojure to make websites. it seems fairly decent. however the only reasonable* way to deploy a compujure site into production seems to be to make a war using leiningen and use something like jetty or tomcat. this strikes me as some horrific enterprise level java horseshit. is this really the price i pay for using compojure or is there a better way. or is the current state of java servlets and things not as bad as i remember? * ie not some poo poo that wont even survive a reboot, jesus christ some of the blogs ive read over the last couple of days,
