Python Development in Emacs questions

I am trying to set up Emacs as a development environment for Python.
So far, I like Python-mode better than the intrinsic Python support. What I am fighting with is auto completion. I want to set the system up so that I can get true auto completion; not just a list of methods and variables I have all ready referenced from the class. I know there are packages out there that do this by analyzing the source, and I know there are other packages that do it by invoking the interpreter. I don''t care which method is used. I also realize that introspection complicates things significantly, so I have no expectations (or real need) to deal with introspection.
The Internet is full of ancient information dealing with Python 2, ropemacs, auto-complete.el, methods of hooking in ipython, dealing with python-mode, dealing with python.el, etc...
Eclipse does a pretty good job of this, but is way to heavy an environment for my taste. So, I ask, what is the Arch state-of-the-art emacs Python environment?

auto-complete.el based on ropemacs provides completion of Python symbols in Emacs. You can find a working configuration of this on GitHub (look at site-start.d/60python.el), which completes symbols of all imported packages from the global Interpreter, and of the current module. Completion of class and instance attributes works to a limited degree, "collections.namedtuple()" (or similar sorts of magic) for instance do not work well. It does not provide the documentation of completed objects.
This setup is the best I've managed to accomplish, and b and large it certainly can save typing. But it is very far away from the kind of completion provided by modern IDEs like Eclipse or Visual Studio for Java and C# respectively, and likely also somewhat far away from the Pydev plugin for Eclipse (never used this one, so just guessing). Particularly, this setup doesn't support the "programming by guessing" kind of style very well, where you guess the semantics and functionality of an object by simply browsing the list of completed symbols. You'll need to have documentation available any way.

Python development environments??

While trying to build the poker-network pkgbuild from AUR I'm having an issue with the error configure: error: No python development environments found.
I have all LISTED dependencies installed. Have searched a bit for this and am having no luck at all.
here is snip of ./configure output

Can anyone point me in right direction please?

Not sure if this is what you are asking for, but the configure command is simply a big honking shell script in the directory that is created when you unpack the package tarball. The job of the configure script is to see what compilation tools and libraries you have, and find where they are. This information is used to customize the package's makefiles. If the configure script fails to find a tool or library that it thinks it needs, it will print an error message, it will not finish creating the makefiles, and the make command will not work. This is what happened to you. If no one posts a better answer, you can peek into the configure script, find the code that prints the last good news, which is "Found working python compilation environment for =2.5", and find the code that prints the bad news, which is "No python development environments found", and somewhere between those two places the script failed to find something it thinks it needed. Studying the script should tell you exactly where it looked for what. Then you either put that thing in the place where the script looks, or tell the script to look where that thing already is by calling configure with an additional option. The list of possible options can be obtained by running "./configure --help".
It's easy to overlook a makedepends item when you are creating a PKGBUILD and already have that item installed, and that may be what happened here.

Beginner iOS developer...questions on the universal UI

I'm a first time iOS developer and working on completing a universal puzzle app that supports iOS 6 and above. On the UI front the main UI has 4 buttons (using a custom UI round button class from cocoacontrols.com) and a About button (at the bottom) that you see in a utlity app (Stocks app). The About button is bigger and I have shaded with blue color. Also, on the iPad, I have increased the size of all the buttons slighty bigger than the iPhone version taking into consideration the bigger screen size of the iPad. Is this OK?. I read in some other forums that I should not increase the size of the buttons relative to the screen size but I have seen a few game apps that show bigger buttons on the iPad than on the iPhone and having the same iPhone button sizes on the iPad makes the screen look smaller with smaller buttons.
My other question is on the main UI, one of the button is a Settings button and when the user clicks, I show a screen with 3 settings inside 3 UITableViewCells. On the iPad, do I have to use a UIPopover controller?. Currently, I'm not using it as the Settings screen is displayed upon clicking the Settings button on the main UI. Also, the iPad version shows the table cells slightly bigger to avoid empty space.
I have included 2 screenshots that relate to the questions I'm asking here.
Please advise.
Thanks.

If you use big button in iphone maybe Apple can reject your app in app store because all apps must have good presentation, good aesthetic and proportional font and buttons.
You could develop differents views from each device iphone and ipad

Some emacs questions

Hi, all.
Recently I became somewhat enthusiastic about the idea of using emacs as a DE. Basically, my reasons are that if you consider the extensions (or modes) for emacs to be apps, they have the following advantages:
-they are all integrated from the very beginning. No need to worry about toolkits, keybindings, etc. This way you get a really flexible environment
-they are lightweight. Yeah, perhaps, it's not as fast and tiny as some C apps are. But after all, I still think that it's hard to get over some 500 megabytes for emacs and all the vital extensions with their respective dependencies
-they are usually just frontends to existing and stable libraries and tools, and such they are pretty reliable.
Besides, the upcoming (it's March 2010, right?) 23.2 should include the Xembed function. Which means, the extensions will be even more interesting. There is already a WebKit webbrowser for emacs, called EZBL (since it's based on the infamous UZBL). I expect a video player to appear some day soon, and that would really mean you can actually do everything with emacs apps. Besides, the interfaces of these modes will get more sophisticated. Actually, if you could just remove the title bar, the toolbar and open Emacs full screen and get the floating mode behaviour for the buffers (not everybody likes tiling) - it would be a full-blown DE, especially if you could use it without any additional WM.
For me, there are already almost all the apps I need:
-text editor with viper (I just don't know yet if I could get VI-like keybindings for everything in emacs). I don't know if viper has all the functions of VIM, but anyways, with Xembed one could probably get vim to work as an Emacs application. Anyways, I mostly work with human language texts, so I don't really need all those text navigation features and regexps. I just think that vi keybindings and modular approach are more efficient.
-XMPP with jabber.el
-audio with EMMS. I guess there should be more options, I am looking for a frontend to MPD
-note-taking, PIM, simple spreadsheets - org-mode
-HTML documents with muse. Or directly via markdown
-IRC with ERC
-e-mail with rmail. I know there are a lot of other options, just didn't have the time to discover those.
-web-browser with w3m at the moment, waiting for EZBL to get mature. Anyways, I do a lot of work in text web browsers.
So, there is my first question: how can I create rich formatted content in common word processor formats. .doc is unlikely, so I am looking for .odt or .rtf. I know I could use latexrtf, I know there is pandoc, I was just wondering if there is something specific to emacs. Especially a WYSIWYG one. I know there is enriched.el, which actually has all the needed features, but can't work with RTF. Is there something else?
Second question is, which WM should I pick. I intend to run emacs full-screened and not use any external apps. I know there are sawfish and stumpwm which are supposed to integrate nicely with emacs and lisp-based environment. I just don't know what benefits does this give, if all the actual window management will be done through emacs? Apart from similar configuration syntax. Another option is probably to use something extra light and stable. CWM, for instance.
Third question: is it possible to manage wifi connections from emacs? Perhaps an interface to netcfg or something? I mean, something useful to laptop users, something with an ability to scan for available connections in a cafe or a university library. If I had something like this, there would be no need for a panel with applets in the external WM.

I've been living in Emacs for a few years now -- it works wonderfully. Though, I have to admit, I still need to leave it sometimes for a graphical web browser and fully-featured terminal.

Everything except the floating buffers (Emacs windows?) is already possible.
.emacs:
;; Remove GUI elements
(scroll-bar-mode -1)
(menu-bar-mode -1)
(tool-bar-mode -1)
.xinitrc:
# Use Emacs as 'WM'
exec emacs -fs
ilembitov wrote:-XMPP with jabber.el
bitleebee + rcirc/erc is rather nice too.
ilembitov wrote:-audio with EMMS. I guess there should be more options, I am looking for a frontend to MPD
EMMS works well enough with MPD once its setup. There are some other options for MPD, though I've not tried them (easily locatable on emacswiki.org). I use EMMS with ogg123 and vlc.
In response to your questions:
1) I don't know of any word-processor formats which are well supported. There seems to be preliminary support for ODT and RTF, but not much more.
2) I've used StumpWM for a year or two in tandem with Emacs. In the end, the problems (crashing, broken features, perceived(?) slowness, binary size, etc.) outweighed any advantage it had from being implemented in CL. I would certainly choose a tiling WM for managing Emacs frames. I now use XMonad.
3) It is possible. I don't believe an extension currently exists for managing netcfg, though I'm sure this would be trivial to implement.

ABAP Development Video legal question

Dear Community,
We would like to create something like a video tutorial for ABAP development for the beginner level based on the flight data model. We might simply put it on our websites unrestriced area, membership area or we might sell this as a product.
The system we are using for this beginner level development activity is the Netweaver Trial version, this is more then enough for this purpose.
Here comes the question; In the license agreement of the Netweaver ABAP Trial version there is this sentence:
"The SOFTWARE PRODUCT is "NOT FOR PRODUCTION USE". You may not demonstrate, test, examine, evaluate or otherwise use the Software Product in a live operating environment or with data that has not been sufficiently backed up. "
I do not fully understand this sentence. Would our activity considered as "production usage" and we might get legal troubles, or a commercial video tutorial is ok?
If we have a problem here, what could be the workaround? Subscription for a system hosted by SAP or maybe subsciption for a cheaper hosting like eg. www.michaelmanagement.com ?
I would really appreciate your oppinion.
Thanks,
Jozep

What about screenshots of all the source code? Or a video of it at runtime?

Seeking for advice over software development start-up question

Hi Admin ,
My friend who is an internet marketer at warrior forum told me about Adobe AIR. He said that programs developed on Adobe Air could not be decompiled. I am a forex software developer that created both a trailing stop ea and forex charting software on the Metatrader 4 open source trading platform. My concern is that the software which i developed could be decompiled.
I have a programming team and they have little or few experience with Adobe Air. I was thinking that before i ask them to research and start developing our software on Adobe AIR platform, could you help us but answering some important questions regarding AIR?
Is it true that AIR applications cannot be decompiled?
Forex software in .ex4 format and .dll files be transferred over to AIR format?
Could there be a communication between AIR and Metatrader 4 trading platform ?
For more info, visit these url :

There is no software that cannot be decompiled and/or reverse engineered. ActionScript is actually one of the easier languages to decompile. There are obfuscators and other protection schemes, but I can't attest to how well they work.
You can write an ActionScript wrapper for dll libraries (in many cases). I don't know what .e4x format is.
An AIR app can communicate with another application or server in a variety of ways. The most common include HTTP and sockets.

Two eMac questions if you don't mind?

I'm running 10.4.11 on this eMac. I haven't upgraded the OS in awhile. Why? I'm pretty sure "Super DRive" has died on me. It will no longer play disk, and when I start up eMac it makes to pretty hideous sound. It sounds like SD is making this noise?
Also, every single time I open up the eMac it opens up Microsoft's Word,and leaves a small square that says I need an Adobe Authentication too. Oh yeah, plus address book opens too! What can I do to stop this upon opening my eMac?

On your second question, open System Preferences, Accounts, click Login Items tab, select Microsoft Word, Adobe (AdobeResourceSynchronizer), and Address Book, and click the minus botton at the bottom of the list. If you have Word or Address Book in the Dock, option-click the Dock icon and clear the checkmark next to "Open at Login".
If the optical drive is making grinding noises, it's a pretty afe bet that an optical lens cleaner isn't going to help. Replacing the internal drive is doable; see Apple eMac Upgrade Guide. If you don't care for the prospect of opening up the eMac, and can live with the startup grinding noises, you can add an external Firewire optical drive for reading and burning CD/DVD discs.

SQL Developer usage (newbie) question - using for script development

I'm new to Oracle, but not to SQL (used MS SQL Server off and on for 3 years prior). SQLDeveloper (v1.5.1) was recommended as a dev tool for the work that I'm doing in in Oracle 10.2.0.4. I'm looking to write some scripts to eventually become stored procedures. The problem I'm having is it seems i can only execute one line even though there are multiple statements in the "Enter SQL Statement" window pane.
ie.
select id, Full_Name, unique_name, user_id from srm_resources;
select id, user_name, last_name, first_name from cmn_sec_users;
when i highlight those two lines and click the "Excecute Statement" button, only the top line generates results.
I'm used to using MS SQL's Query Analyzer where I could select one statement or multiple statements to execute, even non-SELECT statements (variable assignments, math, control loops). It does not appear that I have this kind of functionality in SQL Developer - or an I not using the tool correctly?
Thanks
Brian

I'm assuming you're meaning the SQL worksheet here. The green arrow icon is execute statement (F9) The tiny green arrow is execute script (F5). I'm currently on 1.5.4 of SQL Developer.
Hope this helps some. I would download the documentation also.

Java Development Tools - jar Question

I have developed a application which i would like to be able to execute from a jar file (i.e. java -jar ... ).
Anyway my gui requires some image files which are in the archive. Its just that when i try to run the application from the archive, it doesnt look within itself for the images and therefore cant find (and wont display) the images unless they are present in the same directory as the archive.
Anyone have any ideas as to how i can get the archive to looke within itself for the images. thanks.

Here is a snippet from one of my programs,
I took a while to work out how to do it from a jar.
Andrew.
ImageIcon icon = null;

iconURL = ClassLoader.getSystemResource("comp202/fsa/vuw-logo-short.gif");

XMLExport - Developer Toolbox Problem/Question?

I am using the XMLExport function of developer toolbox but have a problem which I hope someone can help with.
I need to retrieve data from 2 different tables for the XMLExport page that have no relating fields to use in my Spry XML Data Set, although i can add each table and create the Export function when I view the XML it is only showing data from the first table Export function. I had thought of creating 1 sql query to pull the database from both tables but I am at a loss with that as well.
Could someone answer why the XMLExport only sees 1 of the tables, or explain how to use 2 tables, I only want the first record from each of the tables without using any relationship.
I am using .asp and CS3
Regards in advance
Ray

Heya Ray,
I would not use ADDT XML export use THIS - Converting Database queries to XML (scroll to the bottom of the linked page for ASP example) it's easier to customize (two DB tables in one xml file) you can embed CDATA.
Granted this may all be possible through ADDT XML export I just find the linked reference easier to use. I used ADDT XMLExport in the past but went on to use the linked reference later on when I needed a way to embed CDATA into my dynamic XML file for spry.
Hope that helps!

EMac questions

Hey everyone,
I just aquired a used eMac but didn't get the software that came with it. It also doesn't want to start too easily and locks up while booting up. Could it be the backup battery? How do you format the drive? And where can I get the software for it? Don't know what OS version is installed on it yet either.
Thanks
Paul

G'day sethsdad,
Using a fingernail, pull down the optical drive door on the front of the eMac. Inside there's a label that tells you all about your eMac - ie CPU speed, RAM, etc etc. (At least, as at time of manufacture)
Basically, no matter which eMac, Mac OS 10.4 would be the best operating system to use. If it's a 1.25GHz or 1.42GHz eMac, you could look at 10.5, but it's slower and not really all that amazing.
Getting either 10.4 or 10.5 now is not a simple job, as Apple do not (openly) sell "old" operating systems. (Currently 10.6) You could try call Apple, and/or any local Apple resellers, and ask if they have an old copy of Tiger (10.4) or Leopard (10.5) to sell you... Or otherwise - eBay's the easiest option.
Don't buy a grey coloured Instal Disc, UNLESS it is labelled "eMac" (and hopefully your specific machine). Grey label discs are designed for the machine they are sold with.
Instead, get a Black label Instal Disc - universal version.
If the machine itself will not start:
Turn the computer on, and hold down the mouse button. This will eject the optical drive. Put the Instal Disc in, and then push the eject button on the keyboard/gently push on the tray to close it.
Now, hold down the "C" key on the keyboard, to make the computer boot from the optical drive. (Alternatively - hold the OPTION key, and it will look for all viable operating systems on the hard drive, any external drives, optical drive, etc, and let you choose which one).
Then just follow the prompts and instal a fresh copy of the Mac OS.
cheers

Old Developer with Old Question

Hi All,
Used to spend a lot of time here, but had kids and haven't done a web site in 4 years. I'm developing a new site for my husband's new business and I'm wondering what size I should make the pages. We used 800px wide and usually made the pages 100% tall to adjust to content. I know monitors have gotten sharper and I'm wondering if pages are still being developed at 800 because of printing issues.
I REALLY don't want to get into creating more than one site for different browsers or monitors sizes and I don't want to deal with javascript to detect browser size either. I'm happy to just go with the basic size that most are using.
Would appreciate any help,
Marti

Resolution is not the critical issue. Browser viewport width is. To make
your decision you need to have some ideas about the following issues -
1. What is the primary target demographic for this site?
2. What are the browsing habits of that demographic? Do they normally have
their browser window maximized on the screen?
3. If they usually have their browser maximized, what is the typical screen
width?
4. If they usually do NOT have their browser maximized, what is the MINIMUM
screen width in that demographic.
5. How do I want to build the page?
a. Fixed width and left aligned?
b. Fixed width and centering?
c. Flexible to fill whatever width from left to right?
d. Flexible (within limits) and left aligned?
e. Flexible (within limits) and centering?
As you can see, this decision is probably much more complex than you
thought, and will require that you know quite a bit about your intended
target visitor and their browsing habits.
If you elect to go with 5a, or 5b, then your decision would be - 'what is
the mimimum browser width I want to support without horizontal scrolling?'.
Once you have determined that minimum supported width, all of your decisions
are made. That's how wide you want your page to be.
If you elect to go with 5c, then you just build your page within a flexible
container (the simplest example - although an obsolet one - would be to use
a 100% width table to hold the entire page). Be aware that pages with
limited text content can look VERY sparse and empty on wide viewports when
built in this way.
If you elect to go with 5d, or 5e, then you would add this sophistication to
your decision matrix -
'what is the greatest width I want to allow the page and its contents to
become?'
In this case, you would use the CSS styles - 'min-width' and 'max-width' on
the primary page container. Just so you'll know, although these styles are
well supported *now*, earlier versions of IE (and some other browsers) will
not support them so reliably.
So - which is it? 8)
> 100% tall
This cannot be easily done on a page that validates. In other words, most
people who say they do this are using invalid HTML to do so. Forget about
worrying about page height - it is what it is.

You'd REALLY not want to do this. It's a waste of time, effort, and
neurons.

This would have nothing to do with it at all. Just slap a print stylesheet
in the pages to handle that eventuality. To read more about this, go here -

Mundane eMac question - Video card

Does anyone know if the Graphics card in my 1.25ghz G4 eMac (768mb RAM) can handle the latest Tomb Raider game (TR 6 I think)?
Here are the requirements
Mac OS X 10.2.6 or later
PowerPC G4/G5
3D Graphics Acceleration required, 32MB VRAM minimum
1 GHz or faster PowerPC required with ATI Radeon 7500 or nVidia GeForce 2mx/4mx
733 Mhz or faster PowerPC required with ATI Radeon 8500 or nVidia GeForce 3 and faster
256MB of RAM
1.3 GB free disk space
4X CD-ROM
Message was edited by: El Deanio

Hi El Deanio
I haven't tried URU, but the site looks good.
The 32 MB VRAM is small isn't it, if compared to the 2005 model PowerMac G5 that has 128MB. The current iMacs 2007 have 256MB of VRAM.
The latest Macs would be about three times faster than you current eMac. I say about three times, because it would be an accumulative effect of faster processor, and RAM, faster BUS speed, larger CPU cache, larger VRAM: easily three times faster .
In defense of the eMacs, they do have fast Hard Drives at 7200 RPM the same speed as the lastest models. I think I'll hang on to my eMac for a few more years yet, if with a bit of luck it might run Leopard if I add more RAM. I skipped Tiger so Leopard might be a bit of a buzz, or it might be slower than glue on this G4. In a couple of months I'll know.
If you buy the game read the packet/web site to see if it is Universal for if it is too slow for the eMac, a Universal version will run on a new model Intel that you might buy in the future.

Developer access key question

Hello,
I am trying to create some domains per a OSS note. the domains are FILE_APPL and FL_EXTN. when I create the first domain, the system prompted me for the developer access key. The BASIS person sent me the key and I entered and created the first domain. I am trying to create the second domain and again it asked me for the developer access key. I typed the same number and I am getting a "incorrect entry" box. when I clicked on the information button, it states that I should only have to enter this key once.
why does the invalid entry box appear when I am entering the same key?
why do I have to enter the key again?
am I doing something wrong in the process?
thanks in advance for the help

Basically, if you are referring to a developer key, you only have to enter this once, but if you are referring to an object registration key, then these are specific to each object, which would be the reason why the key doesn't work for the second object. It appears that the first is ok, so you now need a second object registration key for the second domain, have your basis person register this object and get the other key.
Read the dialog carefully, it probably says about registering the object and not entering the developer key.
Regards,
Rich Heilman

Future Developement of MBSA question

I saw the following post and need some official Microsoft announcement/statement for this. If MBSA is no longer going to be developed what will be replacing it?
There's no active development on the MBSA tool, so this has not been fixed - nor is it likely to be fixed in the foreseeable future.
