The prescribed order was to install XP and then Linux on a different device/partition. Linux would install Grub or LILO in MBR with dual boot options.
Hence, the easy way to clean up Grub or LILO was to boot into DOS from a CD or floppy and run ‘fdisk /mbr’
If you have CPU intensive workload, an optimizing compiler can help. Well, for that you have C or other languages with more mature and aggressive compilers.
The additional delay it added for checking the state resulted in deadlock timer triggering a dump! Hence, checking a variable is very expensive.
In a spin lock, the lock state is checked in a tight loop by all waiters. This will be using some sort of memory fence. FWIK, memory fence or barriers flush the CPU cache and would initiate reading the variable (spin lock state) for evaluation. I would expect spin locking overheads to increase with number of cores.
On NUMA, I think flushing is more expensive. Hence, spin locks have an additional overhead of having to load and evaluate on every spin as against being woken up for mutexes (like a callback)
I have seen a patent to use SSH to administer a storage system! It was just depressing and sad to see such patents granted and the inventors bragging about it.
I miss nothing, actually feel good staying away from all the toxic comments on Twitter.
I did not need Light Phone or burn a hole in my pocket to achieve this. Plain simple determination.
You end up becoming hyper sensitive at work, start taking everything personal -well, it is your identity or ego at stake. Leads be becoming very closed, guarded and aggressive. Everyday becomes a fight for survival.
I personally went through this phase for a long time. Looking back, some of my managers exploited this by reinforcing. They knew if they compare me with anyone, I would up the competition and perform even better. This did not cost them money since I had invested myself, my identity and ego 100%. Overall, resulted in a highly competitive team but extremely stressful and caustic!
After changing teams, I decided to take a step back and make a fresh start. I now work for the love of my work and do not let it represent who/what I am. It is my identity at work. Back home or with friends, I have a different identity. Having multiple things to fallback has made me more resilient and lot more positive.
Using surveillance and improving attendance through fear tactics is not going to help. You will get their physical presence but not their involvement.
I wonder how long it will take for students to start placing check Bluetooth devices in all places they are expected to be present and remotely switch them at desired times. I hope this happens and defeats this unethical forced surveillance by colleges.
Alternatively, I would encourage student counselors spend a little more time with students and assist them to monitor themselves. Motivate the youngsters to better regulate themselves and grow up to be independent and responsible adults.
Note: On Android, there is an app named Tasker. You can automate your phone with it. Schools could start maintaining shared Tasker profiles that can help students stick to some well defined and commonly followed routines. This is giving control back to the student and coaching them about the merits in planning and sticking to plans.
Developing the humility and truly believing that we are all snowflakes and willingness to learn from the diversity around us is a big step forward.
I loved the analogy between leaders and bridge builders. I always considered leaders as those who build a pedestal or platform or ladder for the rest to use and grow. Very similar.
It gives me confidence and courage to take up a few courses myself and enjoy learning and not just go after grades.
Optimizing FUSE is an example: https://extfuse.github.io/
I expect custom security auditing software, reverse proxies, firewalls with rule engines implemented in eBPF in the coming future. This will avoid having to copy dates across kernel and user boundary and the switching overheads.
I would also like to get my hands on Resnick and Halliday books that I studied back in India during 11th and 12th.
Finally Go gets it ahead of the other languages!
Exported the passwords and imported it into Enpass. That was the first step in liberation.
I then decided to keep my personal and work related browsing separate especially since both require a google account (Gsuite at work). I wanted an ability to open the browser of my choice based on the URL I click and work anywhere on MacOS.
I implemented a simple URL handler that I register as default browser and that opens the clicked URL in appropriate browser:
https://github.com/hackworks/chromer
It is not a very polished implementation but has been working reliably so far.
With that, I am now able to switch between any browser without any lock in.
Apart from a very few, every accomplished technologist have started using Twitter and their followers to attack others. This is nothing but the witch hunt from medieval times done differently.
I have interacted with RMS in Emacs developer list, he has a strong opinion and nothing more, nothing less. He is not trying to create a mob and nor is he starting an upraising. If you have an opinion, voice it and leave it. Yes, I agree RMS needed a PR to tread the land mine ridden modern life.
Overall, it is sad to see RMS and his work getting trivialized for totally unrelated reasons.
Little orthogonal: It sort of rhymes with the mono repository versus collection of micro repositories mindset. Does BSD have more code reuse since it is whole system?
I would enter the lab and start playing all files before starting work on my project - Developing software for Finite Element Analysis. It was like an old gramaphone playing the same tunes everyday and others in the lab hated me.
Since I would get in first, I had the right to start the player :-)
