Small rant about Firefox 26 and Download manager

So we got new Firefox 26 with brand new and ‘improved’ download manager. If you are like me you were changing browser.download.useToolkitUI setting in about:config in previous versions. Well, that doesn’t work anymore, as the devs physically removed piece of code for good old manager. I was quite happy with that oldschool look because there was nothing but downloads, now you have also left space occupied with bookmarks links etc. <irony>Thanks!</irony>

Oh my. Why every company today thinks that changing stuff which JUST works is going to improve something?

Intel 520 120GB SSD review

Just installed brand new Intel SSD drive to my laptop. I am going to share 1day experience.

The beginning

The package is just SSD with no cables, screws, nothing. Just SSD. And Intel “Speed demon” sticker. But that’s it.

Installation

I created bootable Windows 7 on usb flash drive using Windows 7 USB/DVD Download tool. Installed SSD and was surprised that Windows installer is failing with “No device drivers were found”. You can find various causes for this problem on net. My was that I plugged usb stick with Win 7 installation to USB 3.0 port instead of USB 2.0. Yeah, it doesn’t work when running from USB 3.0. Problem solved.

Note: You don’t need to change SATA mode in BIOS to IDE, it can be AHCI.

Benchmarks

Note: My laptop has only SATA II, so don’t be surprised that results are not as good as advertised by Intel.

Tweaks & tips

Windows 7: disable prefetch, superfetch, disk defragmenter, windows search. Also Change location of TEMP files folder to another drive. Or better use RamDisk.

Install Intel SSD Toolbox.

Intensive writing of lots of small files to drive will significantly reduce lifetime of SSD. So for example it means Firefox cache should be moved to RAM or other HDD. For Firefox consider moving profile to another drive.

Verdict

Windows 7: Boot is greatly improved, it is about 12seconds from cold boot to usable desktop. Nice.

Applications: Startup is improved a lot, but depends on application. For some you will not notice any difference. For example IE9 starts instantly, IntelliJ IDEA is slightly faster than on regular drive (but not instant), Firefox startup improved a lot (under 2sec).

So overall big satisfaction with this particular SSD.

The Case of missing check constraint

Few weeks ago I discovered bug in Microsoft SQL Server Management Studio 2012 (SSMS for short). When you execute sql script which is modifying constraints on table (adding Cascade rule for example), you will not be able to see them in designer, even if you refresh tables in Object explorer.

Solution: Close SSMS and start it again. Then you can see the rules just fine.

Connectify + Comodo Firewall = Can’t connect to internet

When you are using above mentioned software for internet access from your Android/iOS device, you might have a problem with Comodo blocking internet from Connectify. By default, your device will find Wifi hotspot created by Connectify, but will be unable to connect to internet. Even if you set Connectify (that means Connectify.exe, Connectifyd.exe, ConnectifyNetServices.exe – see more at Firewall/Security Settings) processes as trusted in Comodo, it will not help.

What will definitely work is this:
  1. Open Network and Sharing Center > Change adapter settings
  2. Find adapter with name you set in Connectify as Hotspot name
  3. Open properties tab and disable “Comodo Internet Security Firewall Driver”

Since I do not use Wifi for internet connection and Connectify is using network cable connection (which is protected by Comodo) I think there should not be a problem with security.
