Very few things are truly necessary in life, programming languages are not amongst them. As I said , for me how already things work in pharo is fine concerning ifTrue: and friends . -- View this message in context: http://forum.world.st/Pharo-dev-Object-if-then-else-tp4693871p4693952.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Cloud Hosting Tip

by Sven Van Caekenberghe

Hi, I am a fan of Amazon AWS's Cloud Services. But it is not perfect. Enter Digital Ocean (https://www.digitalocean.com) an easier to use, simpler cloud hosting provider, that is cheaper and seems faster. You get a raw machine, so you still need some basic Unix admin skills, but apart from that it cannot get much easier. For just $5 a month you get this: As an SSD based machine, it feels very fast. I did some quick benchmarks at the Pharo level which show that this virtualised hardware is up to 10x faster than an Amazon AWS EC2 micro instance, and up to 3x faster than an Amazon AWS EC2 small instance. Its just a bit slower than my top of the line MacBook Air: root@stfx:~# ./pharo Pharo.image eval '1 tinyBenchmarks' '764749813 bytecodes/sec; 94679619 sends/sec' To get started on the empty machine, just do root@stfx:~# curl get.pharo.org/30+vm | bash If you picked a 32 bit Ubuntu, you only need to do root@stfx:~# apt-get install libssl0.9.8 Starting a Zn server is dead easy: root@stfx:~# ./pharo Pharo.image eval --no-quit 'ZnServer startDefaultOn: 1701' & Have a look at: http://82.196.12.54:1701 Which is a single vm+image instance. Local network performance is quite good: root@stfx:~# ab -k -n 1024 -c 4 http://localhost:1701/bytes Server Software: Zinc Server Hostname: localhost Server Port: 1701 Document Path: /bytes Document Length: 64 bytes Concurrency Level: 4 Time taken for tests: 0.584 seconds Complete requests: 1024 Failed requests: 0 Write errors: 0 Keep-Alive requests: 1024 Total transferred: 243712 bytes HTML transferred: 65536 bytes Requests per second: 1753.68 [#/sec] (mean) Time per request: 2.281 [ms] (mean) Time per request: 0.570 [ms] (mean, across all concurrent requests) Transfer rate: 407.59 [Kbytes/sec] received I also tried a big config based build that downloaded and compiled about 1Gb worth of .mcz and that took less than 4 minutes which is also quite fast. Of course, you get way fewer features than with Amazon AWS (the total ecosystem). But for the price it seems hard to beat. Have fun !

on:do: for shortcuts?

by StÃ©phane Ducasse

Hi guillermo I thought that we decided to change and not use on: do: for shortCuts (I'm happy that we change because for me it took me a while to understand that the key was not an exception. Could we deprecate on:do: on KMDispatcher? What is the replacement? onKey: do: initializeShortcuts "initialize the inspector' shortcuts with the dictionary defined in self shortCuts" self shortCuts keysAndValuesDo: [ :key :value | list on: key do: value ] => initializeShortcuts "initialize the inspector' shortcuts with the dictionary defined in self shortCuts" self shortCuts keysAndValuesDo: [ :key :value | list onHold: key do: value ] Stef

ifEvaluatesToTrueUsing sounds like an overkill to me and unnecessary , its common convention in all popular languages than an if always needs to evaluate to true to execute and if it evaluates to false then "else" handles it. -- View this message in context: http://forum.world.st/Pharo-dev-Object-if-then-else-tp4693871p4693945.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
