• Unicode special characters - Dingbats - Appear differently in Firefox vs. Chrome/IE

  - by Oren

  Hi there, I'm trying to find a way to make dingbats appear exactly the same in Firefox, Chrome, Safari and IE. I noticed that the Dingbats appear the same in IE/Chrome/Safari, HOWEVER - in Firefox - they look "thiner". For example - try to visit the following page: http://en.wikipedia.org/wiki/Dingbat You'll notice that when viewing that page in Firefox - the characters look different in comparison to Chrome/IE. Does anybody know why and how can I cause Firefox to display the characters EXACTLY like they appear in Chrome/IE? Thx, Oren.

• Exposing business logic as WCF service

  - by Oren Schwartz

  I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? If so, why? Do you know anyone who had a similar experience?

• Exposing warnings\errors from data objects (that are also list returned)

  - by Oren Schwartz

  I'm exposing Data objects via service oriented assembly (which on future usages might become a WCF service). The data object is tree designed, as well as formed from allot of properties.Moreover, some services return one objects, others retrieve a list of them (thus disables throwing exceptions). I now want to expose data flow warnings and wondering what's the best way to do it having to things to consider: (1) seperation (2) ease of access. On the one hand, i want the UI team to be able to access a fields warnings (or errors) without having them mapping the field names to an external source but on the other hand, i don't want the warnings "hanged" on the object itself (as i don't see it a correct design). I tought of creating a new type of wrapper for each field, that'll expose events and they'll have to register the one's they care about (but totally not sure) I'll be happy to hear your thoughts. Could you please direct me to a respectful design pattern ? what dp will do best here ? Thank you very much!

• How do I change the volume control icon?

  - by Richard Oren Pincook

  I recently switched to gnome 3 (love it!), but the default icon theme was a little dreary and gray, so I switched that back to ubuntu-mono-dark. But now whenever I change my volume, I get this ugly pixelated icon show up. The forum says I don't have enough reputation to post an screenshot, but it's pixelated and ugly with these fuzzy straight blue lines that turn on as the volume goes up. I found identical images in the Humanity and Humanity-Dark icon themes (one example: /usr/share/icons/Humanity/status/24/audio-volume-high.png). I tinkered with the images by changing their names, temporarily deleting them, etc. But it had no effect on the ugly icon. What file is responsible for violating the beauty of my desktop?! Once I find it, I can replace it.

• Android loading screens blocking, good practice?

  - by Oren

  I've noticed many (if not all) android games don't support the "back" button functionality during their loading screens. Which leads to some frustrating moments when a user accidentally starts up the game and has to wait for the long loading stage to end in order to close it. So my questions are: 1) Why is that ? Is there a good reason to avoid something like asynchronous loading (or some other solution to this problem) in android games ? 2) If there is no good reason not to support this functionality, what would be the best way to accomplish it ?

• image focus calculation

  - by Oren Mazor

  Hi folks, I'm trying to develop an image focusing algorithm for some test automation work. I've chosen to use AForge.net, since it seems like a nice mature .net friendly system. Unfortunately, I can't seem to find information on building autofocus algorithms from scratch, so I've given it my best try: take image. apply sobel edge detection filter, which generates a greyscale edge outline. generate a histogram and save the standard dev. move camera one step closer to subject and take another picture. if the standard dev is smaller than previous one, we're getting more in focus. otherwise, we've past the optimal distance to be taking pictures. is there a better way? update: HUGE flaw in this, by the way. as I get past the optimal focus point, my "image in focus" value continues growing. you'd expect a parabolic-ish function looking at distance/focus-value, but in reality you get something that's more logarithmic

• difference between adobe flash media server products

  - by Oren Mazor

  Hey folks, I've been told that I can only record streams with flash media interactive server. I already have Flash media streaming server running to stream flvs. it would seem to be trivial to set up the interactive server, and adobe obliges me by having a developer download. however, once I extracted that download, it appears to contain just standard flash media streaming server? is adobe screwing with me? the more I look into this the more it seems that nobody is actually differentiating between the two except adobe (who charge $1000 for fms, and $4000 for fmis).

• c# order preserving data structures

  - by Oren Mazor

  Oddly enough, MSDN has no information on the order preserving properties of data structures. So I've been making the assumption that: Hashtable and Hashset do not preserve the insertion order (aka the "hash" in there is a giveaway) Dictionary and List DO preserve the insertion order. from this I extrapolate that if I have a Dictionary<double,double> foo that defines a curve, foo.Keys.ToList() and foo.Values.ToList() will give me an ordered list of the scope and domain of that curve without messing about with it?

• Reverse engineer an ORM

  - by Oren Mazor

  Given a [mysql] database with a given schema, is it possible to generate an ORM interface for it? doesn't matter if its php, python or perl. in other words, I have a database and I have to ask it a few questions. while I could just craft a bunch of SQL queries (okay, several dozen), this is way more interesting to think about. is this a valid question, even? I have no design background with ORMs, but I've used a few (django's, symfony's, etc).

• How can I automatically encode a folder of wmv files to flv?

  - by Oren

  I have a folder in which .wmvs are saved after they are finished recording. I would like to set up a script which encodes all of the files in this folder into .flvs with the appropriate size, frame rate, etc and then moves them to another folder. I have been looking for a command line .wmv to .flv converter to do this without much success. Has someone automatically encoded .wmvs to .flvs before that can point me in the right direction?

• cs5 building swf for the wrong version

  Hey folks, I'm pretty new to flash, so maybe I'm missing something. I'm using CS5 flash professional to build a swf. I have it publishing to flash 8, actionscript 2. but it will only work with browsers that have 10.1+ plugins, no matter what I try. is there something really obvious that I'm missing? Edit: I'm using swfobject.embed. it looks like this: swfobject.embedSWF("/foo.swf", "myContent", "400", "300", "9.0.0", "/foo.swf", flashvars);

• Apache returning text/html on some png files

  - by Oren

  I have an Apache web server that has a sub folder for images. For some reason, a few of the .png files are returned as text/html and not as image/png. There is nothing indicating a permission problem and the files return with code 200 and with full size. I made sure that image/png is set and even tried forcing it with .htaccess Any idea where to look next? Edit: looks like an .htaccess configuration problem on a parent directory.

• dynamically decorating objects in c#

  - by Oren Mazor

  is it possible to easily and dynamically decorate an object? for example, lets say I have a List<PointF>. this list is actually a plot of the sine function. I'd like to go through these points and add a flag to each PointF of whether it's a peak or not. but I don't want to create a new extended SpecialPointF or whatever, that has a boolean property. judge me all you want for being lazy, but laziness is how awesome ideas are born (also bad ideas)

• What is the easiest way to make your browser refresh a page every say, 5 seconds?

  - by Oren A

  Is there a browser that supports refreshing a page every say, 5 seconds? Is there an add-on? If not, is there a more simple way than writing a full (C# or Java) program in order to do that? Added: Opera is horrible! I set Stack Overflow to refresh every 5 seconds, but when I click on a post, it refreshes it every 5 secs too! I just wanted the main page to refresh every 5 seconds. Another "Added": apparently it refreshes the current tab, so as long as I open the post in a new tab, it works great.

• generating an asp.net web application dll requirement list

  - by Oren Mazor

  I'm trying to set up a web app (32bit on ii7/win7, 32bit setting is enabled, everything is compiled to x86, using vs2008), but there's clearly some dll module loading issue happening. I've been watching procmon and fusion logs but I'm not seeing the name of the missing dll. I'm a complete newbie to asp.net (but fairly heavy experience on other platforms). I know I can call depends.exe on a binary to see what the dependancies are, but how do I do it for asp.net? specifically, is it possible to get a list of the dlls that iis7 loads for my application?

• maintaining a large list in python

  - by Oren

  I need to maintain a large list of python pickleable objects that will quickly execute the following algorithm: The list will have 4 pointers and can: Read\Write each of the 4 pointed nodes Insert new nodes before the pointed nodes Increase a pointer by 1 Pop nodes from the beginning of the list (without overlapping the pointers) Add nodes at the end of the list The list can be very large (300-400 MB), so it shouldnt be contained in the RAM. The nodes are small (100-200 bytes) but can contain various types of data. The most efficient way it can be done, in my opinion, is to implement some paging-mechanism. On the harddrive there will be some database of a linked-list of pages where in every moment up to 5 of them are loaded in the memory. On insertion, if some max-page-size was reached, the page will be splitted to 2 small pages, and on pointer increment, if a pointer is increased beyond its loaded page, the following page will be loaded instead. This is a good solution, but I don't have the time to write it, especially if I want to make it generic and implement all the python-list features. Using a SQL tables is not good either, since I'll need to implement a complex index-key mechanism. I tried ZODB and zc.blist, which implement a BTree based list that can be stored in a ZODB database file, but I don't know how to configure it so the above features will run in reasonable time. I don't need all the multi-threading\transactioning features. No one else will touch the database-file except for my single-thread program. Can anyone explain me how to configure the ZODB\zc.blist so the above features will run fast, or show me a different large-list implementation?
