Terminal User Interface

Conceptual Ideas

The idea about the terminal implementation is that on any computer (Windows, Linux, Linux server edition, Unix,…) the application can be ran the old-skool way, using command line aka terminals. The ideas explained on this page are only conceptual ideas so far. Implentation hasn’t started yet on this topic and even if it was those conceptual ideas stay conceptual.

Rekomendasi Printer


Sedikit rekomendasi untuk printer rumahan. Kemarin baru saja beli printer Canon MP 287, cukup bagus dan sudah dilengkapi dengan sistem tinta infus. Setelah itu browsing2 tentang kriteria printer yang baik. Canon sendiri dengan thermal head print teknologi + infus sudah lebih dari cukup untuk penggunaan rumahan.Thermal print head menggunakan elemen panas untuk memuaikan dan mengeluarkan tinta dari catridge. Setelah menggunakan untuk keperluan pribadi ternyata kurang. Mengapa saya bisa katakan kurang? Continue reading Rekomendasi Printer

How to use firmware recovery function of Pharos CPE

How to use firmware recovery function of Pharos CPE

Suitable for: Pharos CPE, Pharos BS

Purpose of this article:
Firmware upgrade may not be successful sometimes, for instance unpredictable power failure during the process, and thus your Pharos device may fail to reboot. This article will guide you how to re-flash the firmware via TFTP.

1. Install the Tftpd32 /Tftpd64 on your computer based on the system type(32-bit/64-bit), here we take Tftpd32 as an example ;
Download link: http://tftpd32.jounin.net/tftpd32_download.html
2. Download the proper firmware of Pharos CPE products, here we take firmware pharos_un-up-ver1-0-0-P25-[20140709-rel51929].bin of CPE510 as an example, then must rename the firmware as recovery.bin;
3. Configure IPv4 address of your computer as, you can click Here to configure static IP for the computer.
Firmware Recovery ProcedureStep1
Connect your computer to the LAN port of CPE510 with an Ethernet cable and run the Tftpd32.exe, then navigate the Current Directory to the folder where recovery.bin is stored.

Power Pharos device off first. Press the reset button on CPE510 and then power it on. Hold the reset button for about 6-8 seconds and focus on Tftpd32.exe interface at the same time. When you see the file transfer progress bar appears as below, then you can release the reset button.

CPE510 will reboot automatically after the file transmission completed, please wait for a while until all the lights on CPE510 are flashing and then perform normally.

After reboot you may follow this link to login the management page of CPE510 again.

1. Please only perform firmware recovery through wired connection.
2. Tftpd32 exe/Tftpd64 exe should be compatible with the Operating System, Tftpd32 exe should work with 32-bit System and Tftpd64.exe should work with 64-bit System.

VBA Excel–Allow Paste Special Only

While recently answering a post on the MSDN forum, I realized that the Robert Gold(Vice President of Business Intelligence in Bostwick Laboratories, Inc) was facing the same problem that I was facing couple of years back when I was working as a Team Leader in one of the BPO’s. The MIS Department was reporting to me and one of the main jobs was to create “Trackers” for various departments. My team used to take hours to design a particular tracker only to realize after few days that the users were spoiling the format of the tracker by copying and pasting. Completely protecting it with a password was not the option. Nor did we find any option in Excel which forced selective pasting. It was then we devised this macro which allowed the user to paste but behind the scenes, converted that paste into paste special – values.

The only drawback of this method is that if the macros are disabled then this won’t work. But thanks to the IT Department, they ensured that the macros was enabled on each and every pc. After that we never faced a problem with users messing up the format of the sheet.

So how does this code work? What is the logic behind it? I would explain this in 3 sections.

JDBC connection to very busy SQL 2000: selectMethod=cursor vs selectMethod=direct? – Stack Overflow


  1. selectMethod=cursor
    • theoretically requires more server-side resources than selectMethod=direct
    • only loads at most batch-size records into client memory at once, resulting in a more predictable client memory footprint
  2. selectMethod=direct
    • theoretically requires less server-side resources than selectMethod=cursor
    • will read the entire result set into client memory (unless the driver natively supports asynchronous result set retrieval) before the client application can iterate over it; this can reduce performance in two ways:
      1. reduced performance with large result sets if the client application is written in such a way as to stop processing after traversing only a fraction of the result set (with directit has already paid the cost of retrieving data it will essentially throw away; with cursorthe waste is limited to at most batch-size – 1 rows — the early termination condition should probably be recoded in SQL anyway e.g. as SELECT TOP or window functions)
      2. reduced performance with large result sets because of potential garbage collection and/or out-of-memory issues associated with an increased memory footprint

In summary,

  • Can using selectMethod=cursor lower application performance? — either method can lower performance, for different reasons. Past a certain resultset size, cursor may still be preferable. See below for when to use one or the other
  • Is selectMethod= an application-transparent setting on a JDBC connection? — it is transparent, but it can still break their app if memory usage grows significantly enough to hog their client system (and, correspondingly, your server) or crash the client altogether
