PyGI AIO 3.12.x for Win32

With the new GObject-Introspection 1.40, gir generation now works with MinGW-W64 CRT and most docstrings issues seems been squashed too. GTK is not on Windows side though, version 3.12.1 looks buggier where an app (in this case gtk3-demo) will lose toplevel window (the one that is native and directed by OS), wish I have screenshot to show (I will). All 3.10  bugs also persist in 3.12, so despite of lots of new features it's really no good at the moment.

GTK 3.12.1 has lots of fixes in the Win32 theme (FYI, it's controlled by compiled-in css files namely gtk-win32*.css) which I tried to backport to 3.8.9 and 3.10.8 with some success, I also made correction on Windows XP specific part. But realized that perfect "theming emulation" is not possible yet with current css feature and event handling.

Overall there are new lots of libraries joined the AIO packages, with over 100 introspected libraries. The 64 bit port is not convincing... In some of my tests GI fail to resolve to existed exported functions of a dll, possibly getting skipped/mangled in the process. At C level, the libraries/apps behave just as good as 32 bit ones, so the problem is pygobject specific here.

Ternyata errornya Indosat kebablasan

Masalah routing "tersesat" Indosat ternyata belum selesai juga (sudah beberapa minggu). Masalah ini membuat pengguna yang hendak browsing jadi seperti diajak main togel. Soalnya rasio tidak tersesatnya 1:10 percobaan. Tapi buat pengguna yang suka download seperti saya ini bukan masalah besar. Lagipula untuk koneksi 128kbps mana bisa buat youtube/fesbuk mau buka buka google+ aja tidak selesai2 doh.

Tapi sebenarnya tinggal pakai Tor saja masalah hampir tuntas. Ya, hampir, karena mbah google agak paranoid sama proxy yang satu ini  (sering di blok) jadi harus pake bing atau lainnya buat pencarian. Dan tidak harus pakai Tor Browser, kamu bisa pakai privoxy sebagai jembatan antara Tor dengan apapun browser pilihanmu (saya masih pakai Opera 12) tinggal arahkan saja proxy addressnya ke localhost:8118 (ini port default-nya)

Kembali ke topik, lalu apanya yang kebablasan? Saya adalah pelanggan Starone unlimited, tepat sebulan lalu saya coba registrasi. Tapi setelah saya kirim INTERNET BLN ke 7825, balasan yang saya dapati adalah "Maaf ada kendala teknis, Silahkan ulangi beberapa saat lagi" lalu saya coba koneksi untuk sekedar cek email ternyata tersambung. Tapi saat saya cek pulsa ternyata belum terpotong biaya bulanan tapi juga tidak terpotong tarif premium  (yang seharusnya terjadi jika tidak berlangganan) justru saya dapat tambahan 23 yups tepat 23. Saya pikir ya sudahlah yang penting bisa ngenet lagi. :-)

Hari ini adalah hari untuk registrasi untuk 1 bulan ke depan, ternyata saya kembali mendapati hal yang sama. :-D

Bentuk kompensasikah? ha ha

O iya mumpung sedang nulis laman lokal, Saya ucapkan selamat untuk Pak Jokowi atas kemenangan PDIP, semoga jadi Presiden RI! JKW4P!

What a handful Calculator !

I got lot of bitter experience with Windows 8.1 but still quite noob with it. Often I click the wrong shortcut for calculator from the start page where I launch App version instead of desktop version which on the next right list.

Just want to show that Software maker will race to make bloatware that parallel with current hardware level. MS said 8/8.1 has lower RAM requirement than 7 (well for some Windows 7 feature cut off that's already make sense). But probably they're after to compromise something else...

The inherently RAM sucker WindowsApp. After took several seconds to launch an eightened/flattened version of MS Calculator Plus (2005), I decide to look how much RAM it took.

A WindowsApp Calculator took 20MB (more than Virtual Box manager need)
A Vista/7 Calc need 3.5MB
And for the record XP Calc is about 750KB

That's roughly 5x increase for each generation to do the same task: crunching numbers. You could apply this comparison to other WindowsApp too. Also imagine if everything ported to WindowsApp...

Maybe when 32GB RAM  is common for consumer PC the next-gen calc will need 100MB to do "1+1" calculation... complete animated full 3d button with raytraced soft shadow and fully reflective OSD. Wait... at the moment it's backward evolution remember? we're heading to low tech mobile device where you can only view, read, write and play. Wake me up when Ipad can construct the next gen Game.

At the background of the screenshot, you can see the container of an App.. uhh ohh remind me of OSX's App bundle eh? Indeed while you could see numbers.exe there, it won't run by just double click on it (not in desktop mode at least). The container (the main folder) is a hierarchy of executable, settings and resources. This I think is how in the future apps will be standardized for Windows hmm I wonder. I need to have a look more at this stuff considering MS unlikely change their mind to retire desktop app in the future.

Windows 8.1 64bit was run as Guest under VirtualBox 4 under Windows XP 32bit

A Retrospect for NT 5

This year I've been using Windows 7 for most of the time and only few month ago I decided to back on XP :-) and now it feels like at home again! In those period I found lot of bugs and the quirk of NT 6 so what's the point of getting new OS if you still have bugs to deal? No apparent productivity increase? Yes W7 doing good job at caching (just about everything that matter cached) but it's also a natural step as system with bigger RAM become common nevertheless XP can do some of that too though not as far.

When I go back with XP actually I just upgraded my system, now with 2.9 Ghz CPU and 8GB of RAM, thats right 8GB RAM equipped with 32bit Windows! I took a little experiment with Win 2003 32bit Enterprise (yep this version support BIG RAM), lot of tweaks required to make it behave like XP such as enabling hardware acceleration, sound, etc next I install RRamdisk because some apps refuse to run without pagefile. I allocate 512MB for OB intel GMA and 5GB for rramdisk (4GB pagefile and 1GB for %TEMP%) and it still spare 2.5GB of free RAM. Everything looks great and snappy. With this system I could run 16bit apps directly (OK via ntvdm) or run 64bit apps via VirtualBox. The key is multitasking, if your apps use RAM efficienly and the OS use less memory then you gain productivity! A 32bit apps usually well designed to work with e.g 2GB limit (so unlike 64bit app no need to worry about an app will eat your entire RAM!) though a further tweaks such /3GB ratio or editbin's LAA flagging will provide another scenario.

How about XP64bit? it still basically a dual system so more RAM needed.

I think about next year when XP no longer supported, well first I'm pretty sure the guys at MSFN will make unofficial Rollup Update like they do for Windows 2000. They made it able (to some extent) run some modern apps especially those not relying too much on Win32 API which updated in every major point release and things like .NET/Java. Before April doom come, I will give a test on that Windows 2000 inside Vbox (internet connected) to prove the 0day exploit buzz considering this Windows receive less patches than XP. If it's true then lets try freeze it with EWF/SteadyState, anyway I believe there many people still using it for good reason.

Happy new year XP! you are longest supported PC OS ever!

Gametop.com Games without Gametop.com Redirection

I like this game library site, there are dozen HQ free racing (my favorite genre) games  for download. As we know the games upon exiting will launch your browser pointing to their site. There seems to be no catch here, no suspicious parameter etc. it's simply "open this url" call, although a googling for privacy concern of these games return a few security paranoid's comments.

Having a look from dependency walker I believe ShellExecute is responsible for the call. I try hex it with another same-length function name of shell32.dll (e.g. CheckEscapes) and yeah that's it.

EDIT:

Steps:

1. Download and install free hex editor: WXHexeditor / HexEditor or HxD
   in this case I use HexEditor.
2. Download the game, in this case Battle Rush.
3. Browse battle rush executable, open it in HexEditor



battle rush.exe

4. In HexEditor pres Ctrl-H to bring Find and Replace dialog, find "ShellExecuteA" and for the replacement use "CheckEscapesA" click Replace All. You'll be asked to turn off read only mode, Click ok :



Replace the function

5. A confirmation of the function being replaced will shown like below. If not, it may be in another name e.g. "ShellExecuteW" -> "CheckEscapesW" just give it a try. You can now save the file. Try run it.

How to build PyGI AIO with Moluccas

Read about Moluccas first, its gcc has experimental CRT targeting for this guide.

MS CRT targeting initially laid by official mingw.org but still far incomplete. At first I thought it would be as easy as set cflag/cxxflag __MSVCRT_VERSION__=0x0900 and add -lmsvcr90 to GCC's specs file, well for a trivial program? yes it can but thats all it can get. As my experiment goes by there are many issues piling up (from incomplete msvcr implib to puzzled LFS/Y3K macros) that forcing me to modify mingw's crt and win32api files to allow a package completely linked to the new msvcrt dll. In the end I decided to add new GCC flags to simplify this: -vcr70 to -vcr110. The flags correspond msvcrt redist version bundled by each release of Visual C++. Even today it still far from complete.

What it has to do with this guide? there is an article wrote by win32 contributors of Gnome framework (or whatever you called it) that explain the concern. While my approach is far cry in comparison to use real thing (yeah I know MSVC has free express edition) it still useful in some cases at least for OSS zealot (even if they use Windoze).

This guide will focus on latest stable version of GTK-related (should be called GObject-related) libraries as this written. The main packages are Glib 2.38.1 + GTK 3.10.2 + GI 1.38.0 + PyGObject 3.10.1 and we are targeting python 3.3 (which use msvcr100.dll). I must tell you though, there is steady progress to support MSVC from upstream at least for major libraries including GI thingy.

If you don't need CRT targeting, you can use any GCC of your preference in moluccas by put it into moluccas root then switch over using setgcc [gcc folder name].

Download moluccas 0.8a, you need to download the following packages:

M08.exe
M08-basemsys.7z
M08-basetools.7z
M08-ccomp.7z and newer gcc
M08-tex.7z

1. Saves all of them in the same folder,
2. Run M08.exe and specify install path (it's a portable installation). Click OK. Correction: If you have conemu instance(s) already run you need to quit all before clicking OK, see Maximus comment.
3. The installer dialog will vanish quickly to bootstrap conemu and continue with extraction. Due to the sheer number of files, the extraction (write to harddisk) will be way slower than what the CPU capable of.
4. Once completed, run conemu.exe to start
5. Moluccas will try to detect any presence of Visual C++ and try to integrate the latest version you have. During first run it also initialize Miktex installation
6. In the end conemu panel will bring the <^> prompt
7. Type spawn to start an instance of conemu. The panel will hide and still accessible via systray icon.

edit:

I will put latest patches and buildscript at https://github.com/tumagonx/pygi-mingw-patches

PyGI 3.10 Windows

In my attempt to update MyPaint I need to update PyGI as well as GTK. During compiling there is worrying result the glib 2.38.1 failed on 7 tests! The tests a bit different from previous versions though (in he past usually it passed all tests). GTK 3.10.2 seems missing def files and the new one isn't look any stabler than 3.6, the usual crashes still there despite major win32 fixes in cairo 1.12.16. Lastly I can't use new bindings (gir/typelib) as it always throw gmem.c overflow error during initialize in addition to that I need to comment PollFD override chunk in gi\overrides\GLib.py. Anyhow the new generated girs will still need diff/merge from those linux version...

So here is the new binaries using older typelibs (from pygi aio 3.4.2). This means no new features at python level, plus bugfixes and probably new bugs in the runtime. Currently only bare gtk included if new typelibs become usable I will add others.

pygi-aio-3.10_win32.7z (python 2.6 unsupported)

EDIT: rev2 and further revisions goes here https://sourceforge.net/p/pygobjectwin32/files

Resuming Download from Depositfiles

Don't know if someone has wrote this before (cause it's so simple). This weekend I desperately need several downloads from one of major filesharing survivor DepositFiles. The files are big and my ISP is slow (worse with shared IP). Don't want to mess with eternal redownload or mess around with onion network, I'm looking for a way to resume the download (without their downloader of course).

I found at least two ways: First to use free URL uploader service which offer resumable download or secondly using wget (or whatever downloader with resume ability).

We will need to get Depositfiles' actual link to do it, as we know the url is in this kind of form http://fileshare*depositfiles* we can use source view or built-in browser inspector to get it. Of course we should never click the download button.

Free URL uploader is probably quite risky business, I have seen this kind service very hard to survive in the past. This time I found http://d-h.st/, the site seems clean and modest but not without problem. As expected, the download is very unstable, keep broken every 1 MB. Don't worry wget will deal with it. Interestingly registration appear to be optional. Just upload and the resumable download link will be provided.

The second way need tool to kill specific TCP connection ala task manager or taskkill, I'm not aware of the availability of the tools under Windows out of box but 3rd party tools such Sysinternals TCPView or ProcessHacker will do.

Essentially what happened is when wget issue resume command the server will get "stuck" but only initially, this is when we need to close wget tcp connection. FYI, closing tcp connection is treated as disconnection from the server so wget will do retry instead of giving up. Upon retrying the "stuck" is "unlocked" and download become resumable.

Enjoy!

Weeks of Maps and TPX

I've been spending 2 weeks dealing with maps for several related projects, exploring several (new to me) better projections such Cahill-Keyes-Waterman and Fuller. Probably GIS guys already knew this stuff but in case anyone (newly) interested in maps I have some tips.

OK first what about google maps, google earth or wikimapia? well if you ever find a reason for not using online resources then read on.

Since many Earth datasets has fall under public use, there are many efforts to bring "open source" friendly yet highly detailed maps for mere mortals. Unless you're GIS guys you may not need SRTM, Landsat, VMAP, WVS, CDC's shapefiles and others as there are several ready to use (or easy to setup) maps for people with zero GIS experience.

Vector maps:
- Wikipedia users have made accessible vector maps here (the most detailed svg): http://commons.wikimedia.org/wiki/File:World98%2B.svg
- Duncan Webb's Cahill-Keyes World Map (draft) : http://www.genekeyes.com/DW/DW-1.html
- Gene Keyes's map sources also made available in OOo draw format (need GIS knowledge) : http://www.genekeyes.com/MEGAMAP-BETA-2/
- CIA's factbook (less detailed but up to date) : https://www.cia.gov/library/publications/download/‎

Raster maps (not ready to use but easy to setup) :
- http://www.paulillsley.com/gia/index.html

Among above vector maps, wikipedia map probably the one that readily editable. For inkscape users, 15MB file is quite common/average but 15MB of just polyline is really heavy one! I have been using Tpx for some months now and it fulfill my need of semi-technical drawing. When I try to open World98+ map above, I thought it will suffocated but Tpx handle this file with just 60MB of RAM. Trying to do this with inkscape will freeze your computer winamp's playback -_-! But then how to edit this file efficiently?

Well in Tpx the drawing area is "barely" movable and zoomable, redraw takes several seconds (at any zoom) but no redraw for undo though. So maybe with more powerful CPU it may do. But there is easier way. Since Tpx spend little memory, you don't need to worry of running out of memory (how convenient).

Tpx don't have layering system like inkscape nor understand xref like CAD. So we do chunked file management.

- break the groups

 - copy-paste each region into new session of Tpx

remember that copy-pasted chunk will preserve coordinate/location, so to merge back simply use copy paste operation again.

- the ideal editing workspace is at country/states level:

Lesson learned:

Good application is the one that have good combination of stability and features not bloatness, and part of the stability is smart memory management. Tpx may lack much of SVG features such as gradient ramp/mesh but talk about mission critical apps: "before you can edit you need to open it!". Sorry if I sounds like making a dig to inkscape, but damn they sure know how to make bloat. I want my old sodipodi back!

 Additional note: In case you wonder how the world98+.svg created from http://commons.wikimedia.org/wiki/File:World98.svg. The metadata says:

"Generator: Adobe Illustrator 14.0.0, SVG Export Plug-In . SVG Version: 6.00 Build 43363)"

yeah a real world app huh!?

The Moluccas 0.8

Version 0.8 is here. I now called it Moluccas (not to be confused as some kind of mollusca).  It can be grabbed at https://sourceforge.net/projects/tumagcc/files/0.8/

The installer is M08.exe and you can pick up which 7z packages to install (categorized) but at least "base" is mandatory. Put all in the same folder and you're ready to install. There is brief overview of what's inside in each package at the link above. It still lack of documentation though only man included.

Enjoy my biggest OSS Collection with build environment!
All suggestions are welcome.

Main changelog:

- Fixes many typos and silly mistakes when tested in Windows 7
- All executable flagged with LAA
- Simplified startup: run conemu to start (old mode console, no longer supported though possible)
- Isolation: this version use ReactOS's cmd completely so it can be run independently of Windows' cmd.
- Installation speedup: Installer will use all cores (1 core/package)
- Explorer integration is disabled to provide zero host modification during startup (can be enabled by invoke molumenu). But many gui apps still write registry entries especially MFC based one.
- Fix integration with MSVS 2010 or (later?)
- Lots of manual tweaking in GUI apps to make it tight and blend in
- Small fixes in mingw headers and xtraposix libraries
