Speed up JPG images loading
by Matteo Nov. 5, 2016

Nov. 5, 2016

Dears, I'm loading a lot of pictures (70) through the method "ImageReadWriter>>formFromFileNamed:". The method is very slow, with images bigger than 5MB. Is there a way to improve the pictures speed loading? Thanks Matteo

But this doesn't really work, somehow the list widget can not handle the selection and scrolling (but the images are shown in full size) : imageModels := (1 to:10) collect:[:i | ImageModel new image: PolymorphSystemSettings pharoLogoForm]. listModel := ListModel new items: imageModels. listModel displayBlock:[:item | | layout | layout := SpecTableLayout row add:#yourself; height: item image height; width: item image width. item buildWithSpecLayout: layout]. listModel openWithSpec > > On 31/10/16 12:26, Nicolai Hess wrote: > > > > > > 2016-10-31 10:19 GMT+01:00 Matteo via Pharo-users > > <pharo-users(a)lists.pharo.org <mailto:pharo-users@lists.pharo.org>>: > > > > > > > > ---------- Weitergeleitete Nachricht ---------- > > From: Matteo <matteob8(a)yahoo.it <mailto:matteob8@yahoo.it>> > > To: "Pharo is welcome (ML)" <pharo-users(a)lists.pharo.org > > <mailto:pharo-users@lists.pharo.org>> > > Cc: > > Date: Mon, 31 Oct 2016 10:18:03 +0100 > > Subject: Spec: Setting rows height of a pictures list > > Hi, > > I've created a list of pictures, i.e. a widget based on > > ListModel where > > each item is a ImageModel. > > > > When the widget is displayed I get list window with very > > thin rows. > > > > Is there a way to control the ListModel rows height? > > > > > > Not if the images have different heights (you can, but it looks > > terrible, because the underlaying list morph does not work for list > > items with different heights). > > > > > > > > > > Thanks, > > Matteo > > > > > > > > >

[ Article ] The code behind Google Authenticator
by Sven Van Caekenberghe Nov. 4, 2016

Nov. 4, 2016

I wrote another article in 'Concerning Pharo': The code behind Google Authenticator Implementing Time-base One-Time Passwords in Pharo https://medium.com/concerning-pharo/the-code-behind-google-authenticator-9c… I was curious how Google Authenticator, an iOS or Andriod mobile app used to implement two-factor authentication (2FA), really worked and how I could implement it myself. Since it is a lot of fun to experiment with and implement this kind of stuff in Pharo, I decided to give it a try. Note: fully documented source code with unit tests included.

moving around parts of GTDebugger
by i.uhnak＠gmail.com Nov. 4, 2016

Nov. 4, 2016

Hi, Is it possible to configure the position of the GTDebugger panes to the previous version: ( http://humane-assessment.com/pierfiles/9e/kmq3rz0d783ks2m12lot6qg34ow8kd/gt… ) With the variables pane being a bit taller. I remember that some people didnât like this layout, thatâs why I am asking whether it can be configured (for people that want to use this layout). Thanks, Peter

DatePrinter
by stepharo Nov. 4, 2016

Nov. 4, 2016

Hi for a little project I need to print date in a nice way (for example french) and I wonder if someone already did that. Right now I'm extracting behavior from Date and putting it in its own class so that I can write testAPI | datePrinter | datePrinter := DatePrinter new. datePrinter inFrench; mmddyyyy. datePrinter for: (Date year: 2016 month: 1 day: 3). self assert: datePrinter print equals: '3 Janvier 2016' I will for fun see how I can add an english and spanish version.

How does Boolean ifTrue work?
by CodeDmitry Nov. 4, 2016

Nov. 4, 2016

I am looking at ifTrue: alternativeBlock "If the receiver is false (i.e., the condition is false), then the value is the false alternative, which is nil. Otherwise answer the result of evaluating the argument, alternativeBlock. Create an error notification if the receiver is nonBoolean. Execution does not actually reach here because the expression is compiled in-line." self subclassResponsibility In order to perform the block, ifTrue must somehow end up evaluating the block, but this code only sends a subclassResponsibility message to itself and implicitly returns itself. Where does the block actually get evaluated? -- View this message in context: http://forum.world.st/How-does-Boolean-ifTrue-work-tp4920873.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Keeping data with an application
by sergio ruiz Nov. 3, 2016

Nov. 3, 2016

Hey, all.. One of the things that I find SUPER necessary when developing an app is to be able to grab data from somewhere else and quickly and easily work on it from my machine. For instance, when I get a bug report that smells funny, the first thing i sometimes do is run a script that grabs the production data, and populates my local database with that data. i am fleshing out a project that i would really like to use Teapot (REST) for. i could then write several front ends in whatever framework/language. I was thinking about using Voyager, but the problem is, the data is VERY relational (see below, if interested).. objects are linked to each other fairly tightly. I donât know if this would be the way to handle the data, as there would be lots of duplication using mongodb as a datastore. Of course, my first thought is Gemstones, but I donât know how to grab the production data and pull it into my local development system. Does anyone have any thoughts on this?Â For those curious about the data design, i am setting up a REST server for an collaborative internet radio applicationâ¦ - there would be a global pool of stations (just streaming urls with metadata, really) - each user can select from or contribute to the global pool - users can add tags to stations (or search through the global stations based on tags) - users can attach comments to stations not complex or intimidating at all, and super easy to model in smalltalk, but not sure about how to store data so that I can quickly grab production data and troubleshoot if if necessary.
