Samsung Epix is the worst phone I have used

I was using Samsung BlackJack II before and was pretty happy with its features and performance. Though I am not much of a windows mobile fan it did solved the purpose pretty well. I was very excited when my contract was getting over and saw that the big brother Samsung Epix was available from AT&T. I placed the order and waited for a loooong week to get my hands on it and Boy the touch screen and optical mouse was amazing. Problems started when I tried to connect this phone to wifi. Stupid phone wont connect to wifi. It will keep asking me for the network key. I turned off security on my wireless router and still this phone will continuously ask for Network key. I did a hard reset on phone and tried again and finally it connected to wifi. But after few mins the wifi connection was lost and it keeps asking for network key again. After 4 hours of struggling to get wifi working I gave up on it. Than I saw that an ID1 patch from Samsung is available. It took me 1 hour to get it up and running on my phone. But after I installed some other issues came up. The phone will go into hibernate/power save mode and in that mode it will drop calls. It will take 30 sec to 1 min for the phone to come up. 6-8 hours of frustration and finally I gave up on this phone. I am now ordering Blackberry curve. Lets see how it goes. I have high hopes on Curve.

Killing a particular Tomcat thread

Update: This JSP does not work on a thread that is inside some native code.  On many occasions I had a thread stuck in JNI code and it wont work. Also in some cases thread.stop can cause jvm to hang. According to javadocs " This method is inherently unsafe. Stopping a thread with Thread.stop causes it to unlock all of the monitors that it has locked". I have used it only in some rare occasions where I wanted to avoid a system shutdown and in some cases we ended up doing system shutdown as jvm was hung so I had a 70-80% success with it.   -------------------------------------------------------------------------------------------------------------------------- We had an interesting requirement. A tomcat thread that was spawned from an ExecutorService ThreadPool had gone Rogue and was causing lots of disk churning issues. We cant bring down the production server as that would involve downtime. Killing this thread was harmless but how to kill it, t

Adding Jitter to cache layer

Thundering herd is an issue common to webapp that rely on heavy caching where if lots of items expire at the same time due to a server restart or temporal event, then suddenly lots of calls will go to database at same time. This can even bring down the database in extreme cases. I wont go into much detail but the app need to do two things solve this issue. 1) Add consistent hashing to cache layer : This way when a memcache server is added/removed from the pool, entire cache is not invalidated.  We use memcahe from both python and Java layer and I still have to find a consistent caching solution that is portable across both languages. hash_ring and spymemcached both use different points for server so need to read/test more. 2) Add a jitter to cache or randomise the expiry time: We expire long term cache  records every 8 hours after that key was added and short term cache expiry is 2 hours. As our customers usually comes to work in morning and access the cloud file server it can happe

Preparing for an interview after being employed 11 years at a startup

I would say I didn't prepared a hell lot but  I did 2 hours in night every day and every weekend around 8 hours for 2-3 months. I did 20-30 leetcode medium problems from this list https://leetcode.com/explore/interview/card/top-interview-questions-medium/.  I watched the first 12 videos of Lecture Videos | Introduction to Algorithms | Electrical Engineering and Computer Science | MIT OpenCourseWare I did this course https://www.educative.io/courses/grokking-the-system-design-interview I researched on topics from https://www.educative.io/courses/java-multithreading-for-senior-engineering-interviews and leetcode had around 10 multithreading questions so I did those I watched some 10-20 videos from this channel https://www.youtube.com/channel/UCn1XnDWhsLS5URXTi5wtFTA
