I had in mind that it is possible to use WebSQL or IndexedDB (on browsers that support them), or even sql.js: https://github.com/kripken/sql.js Demo: http://syntensity.com/static/sql.html The demo consumes 23 MB on Chrome while the new search page consumes around 40 MB. Of course these numbers are not to be compared directly and I don't mean to make any comparison. I just looked at it and cite it as a clue that it may be viable performance-wise (i.e. sql.js itself apparently doesn't take hundreds of megabytes of RAM).

[racket-dev] Link to FLOSS Weekly on the Racket home page [Firefox problem]
Hello, I was browsing the website when I noticed that apparently the link to Matthew's interview became somehow less readable. It turns out that the problem is specific to Firefox. With Chrome or other Webkit-based browsers I see spaces between the words, but this is what I see on Firefox 8: http://imm.io/dwU5 Is it a known problem?

If we want to keep that working (which I think we do), then that ties our hands much more. I believe there are some other crufty things in net/url (having to do with encodings?). I've reported some time ago that I had problems with non-UTF8 encodings, such as uri-decode etc calling /utf8 functions instead of using byte-strings. If time would permit I'd implement supplementary versions of those functions to work on byte-string and make no assumptions on encoding. But in case a new library is in the way, then I think it can be made so that it doesn't assume any particular encoding.

Re: [racket-dev] SIGSEGV MAPERR si_code 1 fault on addr (nil) when inserting rows via db / SQLite
Eric, I can't help fixing the problem with your current code, but I can point you to the docs where Ryan says you should probably use functions like start-transaction, commit-transaction and call-with-transaction (in case you missed those). http://docs.racket-lang.org/db/query-api.html?q=db#(part._transactions) PostgreSQL, MySQL, and SQLite connections are discouraged from using transaction-changing SQL statements So, for example, (query-exec db BEGIN TRANSACTION) becomes (start-transaction db).

Re: [racket-dev] Bison
Hello, There is an example lexer and parser from the parser-tools collect for Scheme r5rs that may serve you. You can check it at collects/parser-tools/examples/read.rkt, or online: https://github.com/plt/racket/blob/master/collects/parser-tools/examples/read.rkt As has been said, the grammar is pretty compact, and probably won't help you much with Jison. See Whalesong, that's a really cool project from Danny Yoo, and has already many cross-browser working examples. It's the first time I hear about Emscripten, and it seems ... wow! Let us know if you can make Racket compile and run using it!

[racket-dev] Access key for search box in Help Desk
Hello, I thought of adding an access key to the search box in Help Desk. Many times when I am using it I want a quick way to move to the search box and perform a (new) search. We could add an accesskey attribute to the HTML input, or use javascript. Accesskey is easy to implement, but different browsers/platforms will end up with different key combinations (ctrl + ..., alt + ...). I'd like to know if more people find it useful, and if there is opposition against accesskey (in favor of javascript or something else).

Just be careful of your hands if you're pressing three-simultaneous-key combinations a lot With Chrome it would be alt+q for example (if input accesskey=q ...) BTW, I blogged an alternative a couple years ago, pasted below. Instead of plt, now, I use r for Racket documentation. Usually I do Ctrl-T to get a new tab, so I don't have to make a decision on whether to replace the contents of the current tab, and which also leaves the text cursor in the AwesomeBar, ready to type my r search. I like this alternative. But for me it would work better to use it against docs.racket-lang.org, so that synchronizing bookmarks across the systems that I use would work. Still, whenever I use a browser without my bookmark it will fail. So, across machines, accesskey would be always there, the only requirement being figuring out how to access the field -- alt, ctrl, ctrl+alt... For people unaware of the accesskey, nothing would change. They can still click on the search box, tab/shift+tab until it is focused, or use Neil's alternative. _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

Re: [racket-dev] Please help me to fix the code
It seems to me that the Design Recipe should come into play. Try to think what's the relation between the solution for a list of length n and one of length n-1.
