Upgrading to Grub 2

    I upgraded to Grub 2.  This is the new version of the Grand Unified Bootloader used by Linux to load the kernel.  Many users especially the newcomers, don't know that after you turn your pc power on a series of events happens before you see your desktop.  First your bios starts, then the bootloader, the bootloader executes the kernel, the kernel loads the init scripts, runs daemons and finally starts X windows. 

    The main difference between a Windows boot and a Linux boot is Grub.  Grub makes it possible to multi-boot.  I believe that next to the os, the bootloader is the next most important software. 

    I opened the gnome-terminal and typed:  sudo apt-get install grub2.  I gave my sudo password and the package manager took care of everything.  During configuration, it warned me that installing grub2 elsewhere but in the MBR is a bad idea.  I know but I'm just too lazy.  I just have to remember not to delete the partition where grub2 resides. 

    I'm looking forward to editing the config file for grub 2 then.

ZFS Unable to System Snapshot, bpool is Full?

I first encountered the problem after a routine update / upgrade of the system. Well there was a kernel upgrade and I have not checked how many old kernels are still left for backups in /boot. Apparently, there was a few and the partition is 85% full. Every software update included a warning because of the restriction in disk space. Also, zfs could not create snapshots. It is also full. This is not very clear to me. Snapshots were suppose to be diff copies so why would it take up a large space. Most of the snapshots are less than 2MB. Or 0MB. Another problem that popped up is the constant freezing of Rhythmbox. I don't know if the config files are corrupted. The CPU cycles from one to the next. Peaks for 5-6 seconds then on to the next CPU. This forced me to download Clementine and Audacious. But both applications do not find the zfs pool or don't show the zfs structure. Why not? My final solution is to reinstall Rhythmbox via snaps. I re-scanned the music libr

Renter's ID and Business Licensing 2023

Last year's business permit application involved an undertaking of submitting lessee list to the Barangay in order to get them ID's including one for the lessor himself. I received a letter of notification just before New Year's Day. It informed me that I might be denied renewal of permits because I did not comply with this undertaking. So the Renter's ID is a serious thing now. When I went ahead and applied for a business permit renewal at the local government office everything went well except they want my list of lessee. So I had to backtrack and go to the Barangay and submit the list. They produced the ID's and I provided the photo ID's and of course have it signed by the lessee. After that, they pointed me to the cashier to pay the taxes and permit fees which totaled php15,305.00 ($280.33) During the payment of Fire and Safety department, they reminded me to bring my fire extinguisher official receipts of payment. I can pick up my new pe

How To Verify iso Image After Download In Linux

I assume that you have downloaded the image / iso file in a folder. Navigate to the folder where the iso is. You have to get the public gpg key for fedora downloads.

Please remember that the signature file (.sig or .asc) should be the first file given on the command line.
