Kaj 15-May-2011 [10651] | The ScripTiny stuff looks very good |
onetom 16-May-2011 [10652] | except bolding doesnt work as a switch (in chrome)... i came across this in the 3rd second of trying it... |
Kaj 16-May-2011 [10653] | Sounds like Chrome's fault, then |
onetom 16-May-2011 [10654] | even in FF the text area loses the focus when i click on the Bold button |
onetom 21-May-2011 [10655x2] | im preparing a redirect to google maps from an rsp script. how can i assemble it in a less low-level way than this: gmaps: http://maps.google.com/maps? response/redirect rejoin [gmaps "saddr=" closest/address "&" "daddr=" params/dest] |
i would need the request/query-string functionality but on my own parameters which has nothing to do w the request params | |
Dockimbel 21-May-2011 [10657] | Untested, but should work: build-query: func [url [url!] spec [block!] /local cnt][ cnt: request/content request/content: reduce spec also rejoin [url "?" request/query-string] request/content: cnt ] response/redirect build-query http://maps.google.com/maps['saddr closest/address 'daddr params/dest] |
onetom 21-May-2011 [10658] | okay, thanks... i was thinking about creating an empty request somehow. that would have been simpler. otherwise i would just overwrite the content... |
onetom 25-May-2011 [10659x2] | Automatic output compression (using deflate method) hmm... it doesn't seem to happen for static files |
is that normal? | |
Dockimbel 25-May-2011 [10661x3] | Yes, it is only supported for RSP output. |
Adding transparent compression for static resources was also planned, but: - it is not easy to support efficiently - when static file serving performance really matters, a fast front-end like nginx is preferable | |
So that feature is low priority unless we can found a simple way to implement it while keeping it efficient and transparent for the user. | |
onetom 25-May-2011 [10664x3] | we are showing around our stuff in thailand, china, hungary while the server is in singapore (ec2) and we are using the non minimized angular.js which is 320k. there would be no reason to use the minimized one if it would be compressed. |
but we dont want to complicate the deploy process by switching between the minimized and non minimized versions, however we need from time to time to check out the source and even tweak it sometimes | |
so for us it would be freaking efficient :) otherwise we are veeeery far from hitting the raw static file throughput ... | |
Dockimbel 25-May-2011 [10667] | You can pre-compress it in gzip format, but Cheyenne will need to be patched to send the appropriate Content-Encoding header (should be part of a dedicated Cheyenne mod, that could also handle the pre-compression on disk). |
onetom 25-May-2011 [10668x2] | i wouldnt even mind calling gzip every time... |
it would still speedup the transfer in most situations | |
Dockimbel 25-May-2011 [10670x2] | Well, writing such mod is trivial, the non-trivial part is avoiding making a mess of the web app folders or cluttering the disk with unused files. |
In other words: give me an efficient set of rules to manage the compressed versions of served files and I will code the mod. ;-) | |
onetom 25-May-2011 [10672x2] | and a plain filesize check, like if 10'000 < select info? file 'size [call "gzip..."] |
i would do on the fly compression only. for "personal" usage, it's a good compromise | |
Dockimbel 25-May-2011 [10674x2] | On the fly: that scheme doesn't work for big files (think 10MB or 100MB |
if you have to re-compress the file on each request | |
onetom 25-May-2011 [10676x3] | maybe if u r serving to a 100Mbit connection from a Pentium I... |
such automatic compression makes sense only for mid sized files, where the file needs to be seemlessly uncompressed on the other side. if the file is bigger, u want to be more specific about the compression method anyway... | |
on the other hand, i just ran a time gzip -c some.avi > /dev/null where the avi was 1.2GB and the runtime was 1m19s on my mac laptop, which is 15MByte / sec, so 150MBit/s roughly.... i use wifi most of the time, which is below 100Mbit usually... | |
Andreas 25-May-2011 [10679] | gzipping angular 0.9.15 reduces size from 330k to 86k in 0.06 seconds on my machine (with CALL/wait of gzip from within REBOL). |
Dockimbel 25-May-2011 [10680] | 60 ms for a single request is way too much. |
Andreas 25-May-2011 [10681] | so on-the-fly compression of only static *.js *.css files would probably be worth it |
onetom 25-May-2011 [10682x2] | muhhahahaaa :) |
that request takes several seconds to download in the mentioned scenarios.. | |
Andreas 25-May-2011 [10684] | those 60ms are worth it if the connection is slower than ~4MByte/sec |
Dockimbel 25-May-2011 [10685] | It is a waste of server resources. |
Andreas 25-May-2011 [10686] | depends on your usage scenario |
onetom 25-May-2011 [10687x2] | even my amazon micro instance is idle mostly... |
it would be a waste if it would be happening constantly.. | |
Andreas 25-May-2011 [10689] | if you have no significant load but your users are typically accessing over relatively slow lines, it would result in a significant speedup. i'd certainly not enable such a thing per default, obviously. but for some scenarios (like onetom's, probably) this relatively slow on-the-fly compression using CALL would still be worth it. |
onetom 25-May-2011 [10690] | what kind of connections do u guys live on? |
Dockimbel 25-May-2011 [10691] | you mean server connections? |
onetom 25-May-2011 [10692] | no, client connections. |
Dockimbel 25-May-2011 [10693x2] | 6MBit/s |
(from home) | |
onetom 25-May-2011 [10695] | even in the singapore hackerspace we have only 10Mbit, which is far from being 10Mbit to most directions, but at home we just have ~2Mbit -- hardly enough to watch utube realtime, then in thailand phuket 2.5Mbit, but maaany many times im on edge 10-25kB/s or just 4kB/s GPRS |
Kaj 25-May-2011 [10696] | Yep, it's a problem that most software is developed by Westerners |
onetom 25-May-2011 [10697x3] | the small instance im running this shit from is a small ec2 instance. it compresses the mentioned file in 44ms for the 1st time, then ~28ms subsequently. no matter how i look at it, it does worth to support this for the usual text mime types, especially within the 10kB - 10MB size range |
Kaj: whats u usual client downstream speeds in the netherlands? | |
s/ u / your / | |
Kaj 25-May-2011 [10700] | I'm on 20+ Mbit/s here |
