Results of an online survey about preferred tyres

I am facing some instability on my car rides and after showing it to numerous mechanics, wheel alignment centers everyone said the same: The tyres have gone bad and they need replacement. The car hasn’t had that much running to justify a tyre replacement so I started looking online for solutions. Finally I have to conclude after much online research that the tyres have gone bad.

With so many tyre brands available in the market at different price points it’s difficult to make a good selection by just reading stuff online and knowing about experiences of friends / mechanics. In a commission driven business model like India where every tyre vendor sells tyres of every company they would obviously try to sell the tyre that will fetch them most profits (exceptions exist, I know!). So to make a good choice I decided to run a survey on Twitter and Reddit. Posting the results of the same. I received total 41 responses.

Call Rate comparison: Per second vs Per minute

A simple graph I made using spreadsheet to compare call rate in per second vs per minute. There was a similar graph somewhere around, but I lost the link and hence I made my own graph 😛

1.5 paisa/second and 45p/minute are common rates in per second and

The PC reset problem with Active PFC SMPS and UPS

I have a desktop machine with a Corsair SMPS which has active power factor correction. I had a Luminous 675 VA UPS before buying my new desktop machine with this SMPS. The cheapo power supplies available in India (which cost a fourth of the cost of branded ones like Corsair, etc) do not employ power

A Linux geek’s experience with Windows 8.1

End of October, my Nexus 4 died, apparently due to a bad battery. What happened was the phone switched off automatically (not the low battery switch off, but at some random % > 50) while using a couple of times. That ended up getting worse by corrupting something leaving the cell radio in a non working condition. There’s no IMEI number, no baseband version and any Android version > 4.2.2 doesn’t boot.

A bit of research on Google yielded not much information. I took it to the service centre and they told me the motherboard would’ve to be replaced which was costing me ₹10000. That’s too much to pay for a 2 year phone especially when you get a completely new phone for that price (well, may be a bit more than that). Meanwhile I found a thread on xda which revealed an de-bricking method using some proprietary LG tools, which unfortunately worked only on Windows. This was a big disappointment for me, but that’s well-known fact that Windows has more market share in PCs than anything else.

I had to try it anyhow, so I first tried playing with VirtualBox’s and QEMU-KVM’s USB Passthrough on my old Windows XP VM (I had it around for working on college stuff… education curriculum in India is highly closed source-agnostic, to the extent some computer engineers won’t even know that there exists an OS called GNU/Linux!), which failed. It works for simple storage devices though, but for some reason the serial device (it comes up as ttyACM0) in the download mode (in which mode the LG tool will send a firmware image) couldn’t be accessed properly in the virtual machine. So I decided to buy a Windows 8.1 key from Microsoft Store, I was kind of sceptical about Windows since I left it back in 2007 because of constantly nagging problems like malware, random slowdowns, freezes, etc and shifted to Linux. Thanks to my student account I was able to buy it at a discounted rate of ₹3499 as opposed to the usual rate of ₹19k for the Pro version. I also noticed that they have a 14 day return policy, so I was a bit okay with the spending.

My hardware configuration is pretty simple, I just have desktop with i5-4670, 8 GB Corsair, 1 Samsung SSD and 2 HDD (WD, Seagate). The HDDs are in RAID0 striping in Linux and deliver good performance compared to a single HDD (read speeds are around 190 MB/s). There are two reasons for having such a simple configuration – first, I don’t game and second, excellent Linux compatibility. I had a thought of gaming since a long time, but never had the courage to face Windows (well, after being used to Linux for 5+ years, I doubt anybody will) and hence never played games.

So, let’s put the hand in lion’s mouth.
