Dell lattitude 6430u drifting mouse pointer

Today i received  a brand new laptop shipped to my home  from my company. I opened it and booted it and immediately I realized something strange that I cant use the touchpad as no matter what I do the pointer would just drift randomly to one corner of the screen. I tried various options and I was surprised to see that even when I touch the sides of laptop that were not part of touchpad area the pointer would drift.  I thought may be its the first boot and somehow using keyboard I finished the initial windows boot. But again after restart same issue.

I plugged in an external mouse and it would work fine. I tried using the joystick pointer and it would also drift.

I tried various options and then thought I got a lemon or something went weird in shipping.  I read a forum about pressing Fn + F6 to disable joystick.  I tried that and it worked like a charm.

WTF this is second issue I saw with Dell, not sure what their QA team tested before certifying the laptop.  Anyways I work 90% using external mouse so I am ok.

I will anyways wipe windows clean and install ubuntu. Hoping I wont run into any more surprises.

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.



I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Email slavery

It seems I have become an EmailSlave. The first half of the day is spent in just answering to emails. There are so many emails where I am copied but I need not be. There are many emails  where its a 1-2 page email and somewhere down someone says @KP please answer this.  So it seems daily my work schedule is:
Signin to newrelic and check anomalies for 15 min. Check emails related production exception report and yes there are a ton of these report daily. Need a better tool here as this model is not scalable. I need to reduce the incoming data at me to only see relevant data like what newrelic does. May be I need to create a webapp out of these emails.Check emails for next few minutes before team callsDo team callsThen again back to checking emails until a I have taken a best shot at answering everyone waiting for my reply.Attend team meetings on Tue/Thu
Being an architect and coder at heart I don't feel satisfied at end of the day if there is nothing tangible getting done at the end.…
