| 08:18 | < catadroid`> | ? |
| 08:21 | <&McMartin> | So, I have here a physical, North American (NTSC) Commodore 128 computer running BASIC 7.0, and I have the standard C128 emulator |
| 08:21 | <&McMartin> | If I set the emulator to do a splitscreen for bitmapped graphics vs text, it turns out this doesn't work; it flickers like Hell |
| 08:21 | <&McMartin> | Unless I configure it to be emulating a European C128 |
| 08:22 | <&McMartin> | So, OK, fine, that sounds like the BASIC chips are different between the two |
| 08:22 | <&McMartin> | So I dumped the ROMs from the C128 and loaded them in |
| 08:22 | <&McMartin> | BASIC can be slotted in, and it flickers *less* but is still a problem in NTSC mode |
| 08:22 | <&McMartin> | Swapping in the equivalent of the BIOS, however, renders it unfit to boot |
| 08:22 | <&McMartin> | Not 100% sure what's going on there, other than "perhaps I have misconfigured my ROM dump there" |

| 10:03 | < abudhabi> | MySQL. I'd like for a few columns to be unique together. As in, as if they were concatenated and only then reviewed for uniqueness. |
| 10:03 | < abudhabi> | Can't key them, because one of them happens to be too large for keys. |
| 10:04 | < abudhabi> | Hmm. Another way to phrase it would be that I want no entries in that table that are duplicates. |
| 10:08 | < abudhabi> | Nevermind! Found that you can group UNIQUE statements. |
| 10:09 | < abudhabi> | Except I can't seem to uniquify a primary key. Argh. |
| 10:09 | <&McMartin> | Primary keys are, IIRC, intrinsically unique |
| 10:10 | < abudhabi> | No, wait, I was clicking the wrong checkbox. |

| 12:27 | < 693AAACAZ> | can anyone here recommend a good guide to parsing PDF? the wikipedia page and the PDF standard are both extensive. |

| 12:31 | < sshine> | parsin' PDF... my life has come to this. |

| 12:33 | <@TheWatcher> | If you possibly can, I'd recommend using a tool like pdf2text and then processing the result of that |
| 12:33 | <@TheWatcher> | because you're walking into a cavern full of sorrow spiders there. |
| 12:45 | < sshine> | I actually can't |
| 12:46 | < sshine> | I'm working on a streaming PDF parser that triggers events as various patterns occur in the stream. |
| 12:46 | < sshine> | I don't think there exists a framework for programmatically reacting to objects in a PDF file as they are encountered while parsing it. |
| 12:47 | < sshine> | (it's a work thing. the milliseconds count.) |

| 16:52 | < sshine> | ugh... |
| 16:53 | < sshine> | ASP.NET is horrible. |
| 16:54 | < sshine> | I just found a bug caused by 'this.searchOptionsPanel.Visible = false; ... this.searchOptionsPanel.Visible = true;' caused the search options to reset their internal value, but not what the dropdowns were saying (the text) |
| 17:01 | <@celticminstrel> | That sounds similar to what happens when you reload a page. |
| 17:13 | < sshine> | yeah |
| 17:13 | < sshine> | ASP.NET and ViewState is a horrible invention. |
| 17:13 | < sshine> | when you switch pages as a consequence of 'events', ASP.NET persists state between pages using a hidden form object with a huge binary chunk in it. you probably know it. |
| 17:14 | < sshine> | so when you get used to that, your site stops having regular hyperlinks and only "LinkButtons" (javascript-powered) |
| 17:15 | < sshine> | and whenever you reload, the page loses its state. a lot of old ASP.NET sites don't even keep track of the state using e.g. URLs, so reloading feels very much like just killing your desktop application, starting it again and expecting it to know where you left off. |
| 17:16 | < sshine> | so, switching between two tabs, the searchOptionPanel disappears, and when it reappears, it somehow remembers the dropdown values, but the so-called WebControl that lies behind it has lost its internal state (what it thinks is selected). |
| 17:17 | < sshine> | besides not using the ViewState this criminally, one could also defer from using WebControls as the 'M' in MVC! |
| 17:17 | < sshine> | my search options only exist within the dropdowns. which'd be fine if they never need to be persisted, but they do. |

| 17:21 | <@celticminstrel> | Hm. Apparently I have Java 8, but 'java -version' yields 1.7. :S |
| 17:21 | <@Tamber> | Java 1.7, JRE 8? |
| 17:22 | <@celticminstrel> | Eh? |
| 17:22 | <@Tamber> | Just wondering if it's a language/runtime environment version difference. |
| 17:22 | <@celticminstrel> | I dunno. |
| 17:24 | <&ToxicFrog> | celticminstrel: update-alternatives --list java? |
| 17:25 | <@celticminstrel> | I'm currently downloading JDK instead of JRE, maybe that's it. |
| 17:25 | <@celticminstrel> | update-alternatives does not exist. |

| 17:27 | <@celticminstrel> | That did it. |
| 17:28 | <@celticminstrel> | So now I can use lambdas when writing Java. Not that I'm planning to write Java anytime soon... |
| 18:13 | < sshine> | yes |
| 18:16 | < sshine> | maybe parser combinators in Java will be more popular. |
| 18:17 | < sshine> | and Linq-like libraries will also be more useful with lambdas. |
| 18:17 | <&jerith> | Couldn't you already have inline runnable classes or something? |
| 18:18 | <@celticminstrel> | Yes. |
| 18:18 | <&jerith> | Aren't those basically lambdas wrapped in several lines of boilerplate? |
| 18:18 | <@celticminstrel> | I don't think they support closures. |
| 18:19 | <@celticminstrel> | But otherwise, yes. |
| 18:19 | <&jerith> | Oh, do lambda mean closures? |
| 18:19 | <@celticminstrel> | I think so? Not quite sure. |
| 18:19 | <@celticminstrel> | It sounded like it from reading the Oracle tutorial page, but there was no example given. |
| 18:20 | <&jerith> | I should probably read the docs or something, but I don't really care enough about Java to bother. :-P |
| 18:20 | <&jerith> | If I need to run on the JVM, there's Clojure and Scala. |
