| 00:31 | <&McMartin> | Programming the Apple IIe's speaker is actually worse than programming the Atari 2600 TV chip |
| 00:31 | <&McMartin> | It's one-bit digital audio and you read from $C030 to toggle the bit. |
| 00:31 | <&McMartin> | The reason Apple II programs never did anything else while playing music or sound is because making actual tones requires a tuned cyclecount loop. |
| 00:33 | < Reiv_> | bloody hell |
| 00:33 | < Reiv_> | That does not seem the best way to do things |
| 00:52 | <&McMartin> | Reminder that like the Atari 2600, the Apple is 1970s tech |
| 00:52 | <&McMartin> | The tech specs are amazing too because there isn't even the tiniest hint of apology |
| 00:52 | <&McMartin> | It's just what you do, right? Replace dedicated circuitry with a programmable microcontroller! |
| 00:52 | <&McMartin> | That's what CPUs are *for*. It's awesome! |
| 00:54 | <&McMartin> | Things you do, however, still have to apologize for even with 1970s tech: nonlinear address spaces |
| 00:54 | <&McMartin> | The first line of text is at $0400 |
| 00:54 | <&McMartin> | You'd think the second line of text would thus be at $0400 + 40, right, since it's a 40-column display |
| 00:54 | <&McMartin> | But no, it's at $0480 |
| 00:54 | <&McMartin> | #0400+40 is actually line 9 or so |
| 00:55 | <&McMartin> | (re "bloody hell" - this also means you can kind of sort of do digital sound by feeding in a series of delays into a reprogrammable loop!) |
| 01:13 | < Reiv_> | (... yay) |

| 06:16 | <~Vornicus> | re cli vs gui: for me as a developer, what I would most want is for things like, idunno, sed --I'd want a thing that would A. show (even in a broad sense) the available options, B. help build the query so that it is correct as regards syntax, and C. offers live preview of the results. |
| 06:31 | <@Wizard> | A terminal with IDE features? |
| 06:32 | <@Wizard> | The preview is generally not doable |
| 06:32 | <@Wizard> | Due to the first time someone writes a massive grep into a 5mil line file and it tries to preview the results |
| 06:37 | <~Vornicus> | Even preview of a small sample |
| 06:53 | <@Wizard> | I suppose it would be possible to write at least something for the coreutils |

| 16:42 | <@TheWatcher> | celticminstrel: re you question about git last night: |
| 16:42 | <@TheWatcher> | REVID=`git rev-parse HEAD`; FULLTAG=`git tag -n1 | sort -V | tail -n1`; TAG=`echo $FULLTAG | awk '{print $1}'`; ANN=`echo $FULLTAG | cut -d' ' -f 2-`; echo -e "Revision: $REVID\nFull: $FULLTAG\nTag: $TAG\nAnnotation: $ANN" |
| 16:43 | <@TheWatcher> | just use the variables in defines/whatever |
| 16:45 | <@celticminstrel> | What's 'sort -V' supposed to do? |
| 16:45 | <@TheWatcher> | sort by version |
| 16:46 | <@TheWatcher> | you can't use the --sort arg to git tag if you want to include annotated tag messages |
| 16:46 | <@celticminstrel> | My sort doesn't have that option. Would -n -t. get a similar effect? |
| 16:47 | <@TheWatcher> | if you don't use annotated tags, FULLTAG=`git tag --sort=v:revision` should work and TAG and ANN can be discarded |
| 16:47 | <@celticminstrel> | Hm, alright. |
| 16:48 | <@celticminstrel> | ...that gives "unsupported sort specification 'revision'". |
| 16:52 | <@celticminstrel> | v:refname looks like it would work. |
