Ektron eWebEditPro5: Run time Error '0'

To contact us Click HERE
Hi Friends,

If you recently moved to any Siebel Maintenance fix packs 8.0.0.6 and above then you might face an annoying issue with Siebel HTML Editor a.k.a Ektron eWebEditPro Editor!

After you apply the fix pack for Siebel Web Server Extension (SWSE), it upgrades the existing eWebEditPro editor from v4 to v5.

After this upgrade a necessary configuration change is not mentioned in the Maintenance Configuration Section, due to which you will notice that any template tried to be opened in the new HTML Editor results into a blank load & if you right click in the editor it results into a error popup window titled eWebEditProLibCtl5 saying, "Run time error '0'"

In order to resolve this, you will need to edit the webeditorctrl.htm file under /$SIEBEL_SWSE_ROOT/public/enu/webeditor/

Find out the below code:

and replace it with below code:

After you do this, make sure you do a CLEAR CACHE in your browser else it will still show Javascript errors like:

This happens as the old webeditorctrl.htm file is used from browser cache for loading eWebEditPro Editor.
So ensure you do a clear cache without fail!

Hope this helps resolve patching issue.

Winner is not the best
----To all CS1101S Schemers in Robot Contest
Although we win the robot contest, we are not the winner.At least in my mind, I do not deserve the winner.When I try to remember the things happening on Wednesday night, things became unbelievable.To be more precise, doubtful.
After the contest, I went back to my place, started thinking what the hell was happening.Before the contest, I had been thinking about how can we win, but now, ironically, I have to think about why we win.One thing is clear. Our robot is not the best.
Although I was excited about the “winner thing”, I could not understand it.As you have seen, in the contest, our robot has one unique and decisive advantage: it starts fast, much faster than other robots.
When Laurence said “start”, when my opponent and I pressed the orange button on the robot almost at the same time, quite strangely, our robot started moving almost immediately, but the other robot waited and waited, until our robot was in front of it...
That’s why our robot could win easily, that’s why games with our robot seemed boring.This "quick start" advantage “killed” other robots. It is like a superpower.The superpower that is unfair.
It became a mystery in my mind, so I really cannot accept the winner.I have been thinking what makes our robot start quickly in the last three days, finally, I got the answer, then I was depressed.
It is not because our robot has faster processor (“CPU”).It is not because our robot reads better code (I wrote the code, I knew it).It is because of one mistake I have made.Not about hardware, not about software, it is about firmware.
The original firmware in the controller is version 1.05, but I downgrade the firmware to version 0.85 since I found my PC cannot upload files through USB cable with 1.05. That’s why our robot is different from others. It has older firmware, and most of the robots use the original firmware (1.05). It turns out that firmware 0.85 needs less time for initialization, so our robot can start much more quickly.
Damn it, I don’t know this before the contest.I hate the feeling that you own something you do not deserve.Our robot design is not creative enough, our program may not be clever enough.Merely because of one mistake I have made, it gives our robot most powerful advantage.We have not even got to test the program in the contest, the game finished already.I know this is lucky, but to me, it is more unlucky.
I apply for this blog and write this article is just to let you know the truth.
Also, winner is not the best. Your robot may be much better than ours.
Some thanks to my teammates,Jingping builds the front slope, which is a quite valuable weapon our robot relies on.Yi Xiang builds the back motor, which offers additional and crucial power to the robot.Hyo Jin is an excellent team worker.My friend Han Jian, gave advices on reinforce front slope.
I was quite enjoying this robot project before the contest, but because of the “firmware-winning” thing, I decide to avoid mentioning it.Now, it is time to dismantle it.

At first, i thought its over! My database is gone...but a few research down the line gave me a breather :)
I was upgrading my Oracle Enterprise Manager (OEM) Grid Control Database from 10.1.2.0 to 10.2.1.0. A Grid Control Database installation does not have a separate DBConsole installed as the Database is also managed by the OEM itself.

So in my particular case, i could simply press OK & then move ahead. The upgrade was almost complete & nothing else was required.

I just reconfigured the LSNRCTL & NET SERVICE NAME using Net Configuration Tool & rebooted my server & my new database was up & running.

However, if you are not upgrading a GC Repository Database, but an actual standalone database, this error should not be ignored as your DB Console would not be upgraded due to it.
You must followup with Oracle & find out why the upgrade for DBConsole failed.

Hope this info helps!

SBL-GEN-03001: Error allocating (null)

To contact us Click HERE
Hi Friends,

Yesterday i came across this rare Siebel Assignment Manager error: SBL-GEN-03001: Error allocating (null) OR SBL-GEN-03001: Error allocating DynArrCreate Organization Skill Items Arr

Logs files were showing up following dump:
GenericLog    GenericError    1    000000024bc70cd4:0    2010-04-15 09:39:12    (asgnrule.cpp (8327) err=3001 sys=2640) SBL-GEN-03001: Error allocating DynArrCreate Organization Skill Items Arr

GenericLog    GenericError    1    000000024bc70cd4:0    2010-04-15 09:39:12    (asgnrule.cpp (929) err=3001 sys=0) SBL-GEN-03001: Error allocating DynArrCreate Organization Skill Items Arr

Due to this, Siebel Assignment Manager component was not getting started & constantly crashing. If you start, it will again stop & crash after few minutes.

This behaviour is particularly related to Physical Memory availability to the Assignment Manager component.
You can setup following log level for your Assignment Manager component to have a quick informative trace regarding the issue:

   1. Object Assignment = 4
   2. Rules Evaluation = 5
   3. Loading = 4
   4. Assignment Manager Generic = 4
   5. SQL Tracing = 2
   6. SQL Parse and Execute = 4
   7. Task Configuration = 4
   8. Component Tracing = 3

In our environment, this issue came up suddenly so it definitely wasnt an Siebel Product issue but something to do with our environment changes.
Further tracing of the logs lead to us that the amount of rules loading was causing the Assignment manager cache to go out of bounds of the total available physical memory on Siebel Application Server.

The only way to resolve this was to follows below steps:
1) Stop Assignment Manager & Batch Assignment components.
2) Delete rulecache.dat file under $SIEBEL_ROOT/siebsrvr/bin
3) Delete or expire all unwanted Assignment rules
4) Start Assignment Manager & Batch Assignment components
5) Allow the new rulecache.dat file to be generated.
6) Now check log to see if Assignment Manager component is still shutting down.

90% of cases, this should resolve the issue. But if you still face the same problem, you need to start investigating from your trace log. Particularly the last queries fired just before you find SBL-GEN-03001 errors being dumped in the log file.

You may also notice 0KB crash_xx.txt files under $SIEBEL_ROOT/siebsrvr/bin until you resolve this issue.
Enjoy!

Reset runtime Apache access.log & error.log

To contact us Click HERE
Hi Friends,

Today morning i got a page from our data center that one of the Production Apache based Webserver diskspace was almost full & most of the space was consumed by access.log & error.log!

Well, i knew this would happen some day since it has been a year we put these machines in Production, moreover we havent setup the log rotation for access.log & error.log.

Now, i had two tasks at my hand...
1) Take a quick backup of both the log files.
2) Reset/Clear the logs to size zero without bouncing the Apache Webserver services, i.e. at Runtime.

Solution:
1) Took a zipped backup on another disk in the same machine:
bash$ zip /d01/Apache_BK/access_log_20052010.zip access.log
bash$ zip /d01/Apache_BK/error_log_20052010.zip error.log

2) Reset/Clear the logs to size zero using /dev/null:
bash$ cp /dev/null access.log
bash$ cp /dev/null error.log

OR

bash$ cat /dev/null > access.log
bash$ cat /dev/null > error.log

Well, using /dev/null is very effective on Linux & Unix platforms, but if you are wondering if we have something similar to that in Windows, then the answer is yes!

C:\>type NUL > access.log
C:\>type NUL > error.log

Just hope that Windows havent locked the log file with an exclusive handle ;-)
If you have a lock on the file & need to reset the log file without restarting the Apache services, then your only option is to install Unlocker (http://ccollomb.free.fr/unlocker/)

Hope this tip helps as no one wants to bounce a Production system just for taking a log backup & resetting its size to zero :-D

Enjoy!

Recompile debian's hpcc with other libs

To contact us Click HERE
I installed hpcc using apt-get, but -- and this is a first -- when trying to run it complained over missing libs.

Why compile?

hpcc

hpcc: error while loading shared libraries: libatlas.so.3gf: cannot open shared object file: No such file or directory

Doing
aptitude show hpcc

Depends: libatlas3gf-base, libc6 (>= 2.7), libopenmpi1.3, mpi-default-bin

apt-cache search libatlas.so.3gf

libatlas3-base - Automatically Tuned Linear Algebra Software, generic shared
libatlas3gf-base - Transitional package to libatlas3-base

and doing aptitude search atlas|grep ^i

i libatlas-dev - Automatically Tuned Linear Algebra Softwar
i A libatlas3gf-base - Transitional package to libatlas3-base

but
locate libatlas.so.3gf
comes up empty.

So build your own:
sudo mkdir /opt/hpcc
sudo chown $USER /opt/hpcc
cd /opt/hpcc
wget http://ftp.de.debian.org/debian/pool/main/h/hpcc/hpcc_1.4.1.orig.tar.gz
tar xvf hpcc_1.4.1.orig.tar.gz
cd hpcc-1.4.1/
wget http://ftp.de.debian.org/debian/pool/main/h/hpcc/hpcc_1.4.1-2.debian.tar.gz
tar xvf hpcc_1.4.1-2.debian.tar.gz
patch -i debian/patches/add-Make.Debian.patch

Edit Make.Debian. For some reason LAdir is ignored, hence the -L option in LAlib

 78 # ---------------------------------------------------------------------- 79 # - MPI directories - library ------------------------------------------ 80 # ---------------------------------------------------------------------- 81 # MPinc tells the  C  compiler where to find the Message Passing library 82 # header files,  MPlib  is defined  to be the name of  the library to be 83 # used.

The above assumes that you've compiled your own openblas as shown elsewhere on this blog. You can use whatever math libs you want. Again, there are a couple described on this blog (acml, netlib blas/lapack, openblas, ATLAS). I've had success with the netlib blas/lapack and atlas (built with netlib lapack).

mv Make.Debian hpl/
make arch=Debian

Hopefully everything went well. Now you need an input file.

mpirun -n X ./hpcc
where X=Ps times Qs (e.g. 3 in the example above).

I put the hpccinf.txt in a shared (nfs) folder (~/jobs), created a file called myhost

tantalum slots=2 max_slots=4
boron slots=2 max_slots=6
neon slots=2 max_slots=8

and then launched using
mpirun -n 4 -hostfile myhost /opt/hpcc/hpcc-1.4.1/./hpcc

Cluster network performance testing (very basic) on Debian Testing using a gigabit switch

To contact us Click HERE
Playing with hpcc got me thinking about my network connection.

My cluster looks like this:
I've got four nodes which are connected via two networks, 192.168.2.0/24 and 192.168.1.0/24. The 192.168.1.0/24 network is connected using a gigabit switch. Be (see below) acts as the gateway. The 192.168.2.0/24 network is connected via a crappy old netgear 10/100 router (dhcp) and provides access to the outside world (hello mac spoofing :) ). Each box shares a folder via nfs using a unique name.
_Nodes_
Be: AMD II X3, 8 GB ram (192.168.1.1)
Ta: Intel i5-2400, 8 GB ram (192.168.1.150)
B: AMD Phenom II X6, 8 GB ram (192.168.1.101)
Ne: AMD FX 8150 X8, 16 GB ram (192.168.1.120)

So, time to test the network performance:
sudo apt-get install iperf

On all your boxes (e.g. using clusterssh) start the iperf daemon
iperf -s

Then on each of your nodes run:

iperf -c 192.168.1.1 && iperf -c 192.168.1.101 && iperf -c 192.168.1.150 && iperf -c 192.168.1.120

Overall, this is what I got
Client/Server (MBit/s)

     Be     B     Ta    NeBe   13.7G  310   308   316B    564    15.5G 564   617Ta   726    660   19.7G 936Ne   882    484   917   19.4G

I'm not sure whether to expect a metric gigabit (1000 metric MBit) or a binary one (1024 binary MBit), but looking at our results our best is 936 Mbit/s and worst 308 Mbit/s. All of them should thus ideally reach at least 936 MBit/s. They all have gigabit network card.

And now, try to improve it:
I went through the whole shebang with
sudo ifconfig eth1 mtu 9000
sudo ifconfig eth1 mtu 8000
etc.
Anyway, I got the following MTUs that way:
Be 7100
B 7100
Ne 9000
Ta 9000

I then set the MTUs to 7100 on all the nodes and tried pinging from node to node, e.g.:
ping -s 7072 -M do 192.168.1.101

Well, that maxed out at 1472 i.e. about MTU 1500 which was the original value. So I'm a bit confused.

Setting up Openchrom (and using it to open Agilent .D ESI-MS files on Linux)

To contact us Click HERE
I've been using Wsearch (http://www.wsearch.com.au/wsearch32/wsearch32.htm) to process agilent chemstation ESI-MS spectra for the past few years. It and Matt Monroe's Molecular Weight calculator (why, oh why is there no comparable molecular weight calculator for linux?) have been the only two reasons why I've bother with Wine under Linux. Openchrom is written in java and so will run on both Good (Linux) and Evil (OS X and Win) operating systems.

Having finally discovered openchrom (v 0.6 so still early days) I can now finally retire wsearch from my own computers (it's still a good piece of software, but it's crippled to encourage the purchasing of a 'full' version, and I've had no luck purchasing a license from the author in spite of having tried several times during the past couple of years). OpenChrom can export an entire agilent experiment as a '3D' csv file which makes processing a lot more fun.

As an aside: I hate proprietary file formats since they prevent me from using my own tools (cat, sed, gawk, gnuplot, octave) when processing -- or at a minimum make it more difficult. Most universities and grant agencies now add a provision regarding data management in their grant acceptance agreements/work conduct policies. In general these provisions state that the data shall be made available publicly and /or managed by a university repository. What is REALLY missing is a clause about using open formats -- and that should be taken into account when acquiring new instrumentation. All else being equal, an instrument which is 'open' will be a lot cheaper to manage in the long run since you won't have to feel locked in in terms of software. That's incidentally a reason why I like Metrohm since they provide details of their RS-232 interface allowing you to write your own software.

Anyway, here's how to get set up:

1. Install Java v1.7 (need > 1.6)
You can either use openjdk 7 or (Oracle) Java. See here for a general guide to installing Oracle/Sun Java.

As for openjdk, you can easily install it:
sudo apt-get install openjdk-7-jdk

(the openjdk-7-jre package is enough if you don't want the full developer's kit)

Anyway.

Make sure that you've selected the right version:

 sudo update-alternatives --config javaThere are 7 choices for the alternative java (providing /usr/bin/java).  Selection    Path                                            Priority   Status------------------------------------------------------------  0            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      auto mode  1            /usr/bin/gij-4.4                                 1044      manual mode  2            /usr/bin/gij-4.6                                 1046      manual mode  3            /usr/bin/gij-4.7                                 1047      manual mode  4            /usr/lib/jvm/j2re1.6-oracle/bin/java             314       manual mode  5            /usr/lib/jvm/j2sdk1.6-oracle/jre/bin/java        315       manual mode  6            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      manual mode *7            /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java   1051      manual mode

2. Get openchrom

cd ~/tmp

wget http://sourceforge.net/projects/openchrom/files/REL-0.6.0/openchrom_linux.gtk.x86_64_0.6.0.zip

unzip openchrom_linux.gtk.x86_64_0.6.0.zip

cd linux.gtk.x86_64/OpenChrom/

sudo mkdir /opt/openchrom

sudo chown $USER /opt/openchrom

cp * -R /opt/openchrom

chmod +x /opt/openchrom/openchrom

Stick

alias openchrom='/opt/openchrom/openchrom'

in your ~/.bashrc and source it.

3. Get plugins
On first boot you're asked whether you want to get additional plugins using the 'Openchrom marketplace'. Since I'm mainly processing data from an Agilent ESI-MS, I wanted the plugin for Agilent files. The website says that you need a license key for plugins BUT that it's free to register for one.

This is a 30-days trial version. Afterwards, you need a valid serial key.You can get a free serial key after registration on http://www.openchrom.net.You can use the converter for commercial or non-commercial purposes free of charge, but you are not allowed to redistribute this software without my permission.

Note, that clicking on links on the website didn't lead me to a link to download the plugin. Instead, in OpenChrom click on the Plug-ins menu:

As always, make sure you trust your suppliers.

And then you're done installing.

There's nothing odd about registering other than this: you will receive an email with a confirmation of your registration in clear text WITH YOUR PASSWORD. So...be aware of that.

4. You can now browse in the tree to the left and select your .D folder:

There's a bit of clever thinking when it comes to the functionality of the program. The upside of this I think will eventually be that it's easy to get a consistent experience for a set of users (not unimportant for a research group). The downside is that it's a bit clunky getting started. Play with it for an hour and you'll get the hang of it, so it's not really that much of a hurdle. Also, too many options seem to be context sensitive -- I am having real trouble finding various options under the 'Accurate' perspective which I can find under the 'default' perspective.

5. Some comments:

It's still early days for OpenChrom (v 0.6) , and there are a few minor issues which may or may not affect you:

* Registration keys. They are easy enough to get (register online, log in, click on the plug in online that you want and you'll see the key), but if you have installed a new plug in and open your first spectrum right after that you'll be asked for registration keys. It won't tell you for which plug in the dialogue you're seeing is though, so if you've just installed three different plug ins you'll have to do some trial-and-error. This is fixed in the upcoming version.

* Raw/gaussian plot of mass spectrum. This took a while to figure out, but you have to use perspectives. The default (heavily zoomed in) view looks like this:

This might be good enough for those organic types...us 108 element inorganic types want more detail

If you go to the top right corner, click on 'other' (perspectives)

and select accurate you get

Bingo!

And then there's the obligatory wish list:

* A good quality isotopic pattern calculator would be nice. Anyone who has compared the output from different pieces of software will have discovered that different calculators may yield very different patterns. I think some of it boils down to truncation rather than incorrect isotopic ratios, but that just highlights how difficult it can be to implement a seemingly simple concept. The only calculator which I trust AND find useful is Matt Monroe's calculator -- the predicted patterns look good, and you get proper Gaussian broadening which means that it looks 'right'. This would be perfect as a plug-in. If only I knew how to properly implement it...

* A good quality ion generator -- some pieces of software (Hi Matt) allow you to select a handful of elements or fragments, pick a range of charges, input an m/z value and based on that spits out a list over possible identities for your signal. It's a good thing to have by your side the first time you look at a complex mixture trying to figure out what products may be present. This would be perfect as a plug-in. I've written this type of programmes before, but in python using for-loops...a vectorized version should be faster and maybe even easier to write.

Matt Monroe's Molecular Weight Calculator under Wine on Linux

To contact us Click HERE
I've downloaded the source code to Matt Monroe's molecular weight calculator in the past, and having replaced wsearch32 (+wine) with OpenChrom I figured I'd go online, download it and see what Mono can do for me. I had a vague recollection that the source code was only freely available online for a short while, and as it turns out I couldn't find it this time.

Anyway, not finding the source code I decided to update my Molecular Weight calculator from version 6.46 to 6.49 which (finally) allows you to set the charge of an ion WITHOUT having the mass of a H+ added for each charge. It's not difficult to compensate for, but it's always confusing to new students.

1. Install Wine and winetricks, add dlls
You can either install wine from the repos (old version)
sudo apt-get install wine-bin

Or you can download a newer, unstable version from dev.carbon-project.org:
http://verahill.blogspot.com.au/2012/01/debian-testingwheezy-64-bit-installing.html

Or you can compile your own:
http://verahill.blogspot.com.au/2012/06/wine-141-and-wine-156-on-debian-wheezy.html

The mono step was a right headache and would fail unless I nuked everything winetricks and wine knew about each other/

To get winetricks and set everything up:

wget http://winetricks.org/winetrickssudo mv winetricks /usr/local/bin/sudo chmod +x /usr/bin/local/winetrickswget http://downloads.sourceforge.net/project/wine/Wine%20Mono/0.0.4/wine-mono-0.0.4.msiwine msiexec /i wine-mono-0.0.4.msi

You're now asked whether to download and install mono...sigh...more often that not this has failed in the past.

winetricks vcrun6sp6

Ignore the window that opened in your browser

cd ~/.cache/winetricks/vcrun6sp/wget http://software-files-a.cnet.com/s/software/10/72/65/52/Vs6sp6.exewinetricks vcrun6sp6winetricks corefontswinetricks riched30wine uninstaller --remove '{E45D8920-A758-4088-B6C6-31DBB276992E}'winetricks dotnet20cd ~/.cache/winetricks/dotnet20/wget http://software-files-a.cnet.com/s/software/10/72/60/27/dotnetfx.exewinetricks dotnet20

Ignore this error. Installation will take a while after that. Have patience. Like 10 minutes kind of patience.

And finally:

winetricks wsh57

2. Download the molecular weight calculator and install
If you go to http://www.alchemistmatt.com/mwtwin.html
you get redirected to here: http://omics.pnl.gov/software/MWCalculator.php

cd ~/tmpmkdir molwcd molw/wget http://omics.pnl.gov/installers/MolecularWeightCalculator_Installer.zipwget http://omics.pnl.gov/installers/MwtWinDll_SourceAndSupportingDLLs.zipls *.zip|xargs -I {} unzip {}unzip MwtWinDll_Source_v3.4.4518.zip

You'll get some warning about Revisionhistory.txt etc. being overwritten. That's fine.

Launch the install with
wine msiexec /i MolecularWeightCalculator.msi

If you try to launch the mol weight calculator at this point you'll get an error about a missing MwtWinDLL.dll:

So sort that out:

cd ~/tmp/molw/binregsvr32 MwtWinDll.dllSuccessfully registered DLL MwtWinDll.dll
[If I tried to copy the dll to the wine structure first and register that copy I got:DllRegisterServer not implemented in DLL C:\windows\system\MwtWinDll.dll]

If it seems weird to install wine-mono and then remove it as is done above, it's to get around a bug which causes dotnet20 installation to fail/

Anyway, you're pretty much done:
wine ~/.wine/drive_c/Program\ Files/Molecular\ Weight\ Calculator/mwtwin.exe

Yay!

Comment:
Getting there was a bit of a trek, passing though a whole lot of different sets of dlls:
winetricks msflxgrd

winetricks vcrun2005winetricks vb6runwinetricks mdac28winetricks comctl32ocx

winetricks comctl32

The solution above should suffice though.

I even ended up installing mol weight calc on a windows box and using dependency walker, but not even that sorted it out -- googling for scrrun did it in the end.

In particular this last error was bloody annoying:

"Object doesn't support this action." What, saving?

"Error saving default options file. Use the /X switch at the command line to prevent this error."

But it was solved by doing winetricks wsh57

Leadtek DTV 1000s in kernel 3.6 (debian wheezy)

To contact us Click HERE
My Leadtek DTV 1000s has been working fine for a long time after the initial set-up, but when upgrading from kernel 3.4.0 to 3.6.0 on my tv computer' it suddenly stopped working.

lspci shows

01:06.0 Multimedia controller: Philips Semiconductors SAA7130 Video Broadcast Decoder (rev 01)

but

lsmod|grep saa

returns nothing and there's nothing that looks right in /dev

Finally

sudo modprobe saa7134
FATAL: Module saa7134 not found.

ls /lib/modules/3.4.0-amd64/kernel/drivers/media

but

ls /lib/modules/3.6.0-amd64/kernel/drivers/media

Basically, saa7134.ko is never built.

I installed kernel 3.6 from deb files compiled on another computer. My first step was to uninstall linux-headers-3.6.0-amd64 and linux-image-3.6.0-amd64

Next, to get the saa7134 module-- roughly follow this post we get

wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.6.tar.bz2

Hello World!!!!!!!!

To contact us Click HERE

Let me first introduce myself .My name is Dam Tuan Long (but just call me James), a Vietnamese guy studying in National University of Singapore(NUS). I am 20 years old. My hobbies are playing games, hanging out with by buddies, reading books, listening to music…
To tell the truth, I do not like blogging at all and I cannot remember how many blogs I have created and then forgot L. This blog is another class blog that is required by a module. This time is CS3216 Software Development on Evolving Platforms taught by Prof Ben Leong. However, I hope that the blog will not be closed down at the end of the semester :P.
That all for the first entry !
Cheers,

“Welcome to Hell !”

Why the title? Because this is what Hung Doan, an ex-student of CS3216, told me when he knew that I would take that module this semester. This really does not scare me at all. I already have experience of how a module of Prof Ben Leong should be. Last semester I took CS3217 Software Engineering on Modern Application Platforms (taught by the same beloved professor) which is stated as a 5 MCs module. However, the work load was at least twice as hard as a normal 5 MCs module so I don’t expect CS3216 to be easier (maybe of the same difficulty level :p ).
In fact, taking CS3216 this semester sadly goes against my plan for graduation. Both CS3216 and CS3217 do not help me fulfill pre-requisites for any 4000-level module in the list of CEG Technical Electives. That means I will have to take some other 3000-level modules next semester. Also, we, third year CEG students, are taking a special project-based module (6MCs) which are told to be equivalent to the old CS3215 (8MCs) L. So why did I decide to take this module? In short, I took it because I think it would be challenging.
And what I want to learn from CS3216:-        Team working. My deadly weakness is communication. Hopefully meeting many great students from SoC and other faculties can help me overcome it.
-        Cloud computing and social networking. Those are actually the core of this module. I have some knowledge of Google App Engine, another cloud computing framework, but Amazon Web Services is just cool. Facebook is great too. However, I hope in the future students will have a chance to work with the evolving Google + ( I am a Google fan).
-        Some other stuffs like PhP, database, flash… I know this is quite like a self-learning module, and I will need to pick up some of them along the way.
Maybe teaching team will bring up some surprising things other than those above. Hope the new semester will be fun!
P/s : I really don’t have any idea of what to bring to the Show-and-Tell section L

Software Engineering: principles and more

So the second lecture of CS3216 is about Software Engineering. To tell the truth, the lecture is not very new to me. In fact, I was taught almost all (maybe all but I forgot) of it in CS2103 and CS3217. Although I thought that Prof. Ben did a really good job in reviewing SE for the programmers, I did not think that a 2-hour lecture is enough for the non-programmers to fully understand the principles of SE.

Since it is like a review lecture to me, I find nothing quite surprising about SE to say about. However, there comes again the question of sharing or not. “Ideas are cheap and plenty”- quoted from our beloved lecturer, Ben Leong. I also support sharing ideas. However, I do not object to no sharing. Sharing is good because you can find someone who have the same interest or can validate your ideas. At least you can evaluate the potential market before making decisions. I am a Google fan because they promote sharing. Google release some of their products (as in Google Lab) to collect feedback from users. Google also like open-source (Android, Chrome web browser…). One good example of not sharing ideas is Apple. They tend to keep their product a secret until it is launched. Both companies are really successful with their own strategies. There seems to be no right answer for the question.

The lecture is no all about principles of software engineering, Prof. Ben also gives me some motivations. I quite impressed (again) by the illustration of the potential bar and start wondering how far to the right I was, I am and I will be. After surviving last semester with CS3217, I found my potential bar is pushed to the right a bit. At the moment what really matters me is not surviving another semester but how to push it further. In CS3216, I met many really interesting people who are all talented and motivated. My team for FB assignment consists of such people. They make me feel that the training I got from CS3216 is not enough at all L (actually can never be enough).

VNC viewer for iPad

To contact us Click HERE

Before the seminar on Monday this week (Aug 29), I do not know that is VNC technology. For me, it sounds like Vietnamese Community :-) (a real community in NUS which is also shorten as VNC) . So for those who do not know about that technology, VNC stands for Virtual Network Computing. It is a graphical desktop sharing system that uses the RFB protocol to remotely control another computer.
I did see some of popular desktop applications that make use of VNC but I have not thought of and iPad application with the same features. That is actually a cool idea. Image how convenient it is for you to control your desktop at company even when you are on the go. VNC viewer (by RealVNC) is one of such iPad applications. Aldrian, Kenny, Yingbo and Aravindh gave us a really great presentation about the app.

I believe that in the future, we will not be be tied down to any location or machine. Cloud computing, HTML5, mobile devices and VNC technology are shaping that future.

Why VNC viewer? Since there are a lot of communications between the iPad and the computer being controlled, the latency of VNC apps are usually slow. For such a not-so-powerful device like iPad, one may expect the VNC viewer to have really high latency .But the control is quite smooth.. It is easy to use and secured. I also find that the encoding technique and picture quality are automatically changed based on the bandwidth available. There are also many configurations that you can apply since the app is catered for difference kind of users. You can use graphical UI for ease of use or CL interface for more powerful control.
There are still things that I do not like VNC viewer. It has too many extensive configurations for the server and network. And new user may not have hard time to get use to moving from using mouse to fingers to control the computer. If it comes to the question of whether or not I will buy the app ($9,99), I will say no. There is another app that does the job named Team viewer and it is FREE. In addition, if you choose VNC viewer, then the syncing software resided in the other machine will cost you another $50 for better quality and support (quite pricey).
In general, I think the presentation is good. However, I would love to see more images or animations on the slides. A demo of how the application works can also make the presentation more successful.

VSee talk

This was my second chance to listen to Mr. Milton, CEO of VSee. Although the content was quite the same, there still things that impressed me (again).
Micro learning: Try to learn every 3 things. For Milton, he considers a day worthless if he cannot do that. I did try to follow him and found out that you can easily do this for a couple of days without any problem but doing this for a long time is quite a big challenge. Other big challenges are not to forget what you have learned and to apply them.
Break patterns: yes, I like creative ideas. And who know by walking to school instead of taking bus, you can find somethings that change the world. Following the rule will make our brain lazy and our creativity weak.
The "Sandwich" method: When you want to criticize someone, start with a compliment, then give the negative feedback, and end with another compliment. The method seem to be complicated but it is really effective. I have tried it a few times and the results are all good. Everyone have a natural defense mechanism that triggers against criticisms.
Aim for boredom: I do not agree with him abt this. Maybe it is true, but the trade-offs you pay for being successful are too much. I always think that life is short and living a short and boring live is so painful.
Marrying the right one is also important.That funny relationship lesson is worth noting. If you are a workaholic, then you must find a suitable one to marry . And settle down first before becoming workaholic otherwise you will not have time to find the right one . Apart from teaching us how to become a good software engineer, Prof Ben sometimes teaches us valuable life lesson. The last lecture of CS3217 was about how to rule a country in one hour :D
