The MySQL binary log

The binary log contains events that describe database changes such as table creation operations or changes to table data. It also contains events for statements that potentially could have made changes (for example, a DELETE which matched no rows), unless row-based logging is used. The binary log also contains information about how long each statement took that updated data.

Ways to get more important things done

Let’s define productivity. Productivity is a measure of efficiency of a person completing a task. We often assume that productivity means getting more things done each day. Wrong. Productivity is getting important things done consistently. And no matter what you are working on, there are only a few things that are truly important. Being productive is about maintaining a steady, average speed on a few things, not maximum speed on everything.

Warren Buffett’s “2 List” Strategy for Focused Attention

Buffett uses a simple 3-step productivity strategy to help his employees determine their priorities and actions. You may find this method useful for making decisions and getting yourself to commit to doing one thing right away

Step 1: Write down your top 25 career goals. Or you could also complete this exercise with goals for a shorter timeline. For example, write down the top 25 things you want to accomplish this week.

Step 2: Review this list and circle top 5 goals

Step 3: Start working on top 5 goals right away. Everything in 20 things that you didn’t circle just became your avoid-At-All-Cost list.

No matter what, these things get no attention from you until you’ve succeeded with your top 5


Who are we seeking to become?

behavior will become part of you

We get what we invest in. The time we spend comes back, with interest.

If you practice five minutes of new, difficult banjo music every day, you’ll become a better banjo player. If you spend a little bit more time each day whining or feeling ashamed, that behavior will become part of you. The words you type, the people you hang with, the media you consume

The difference between who you are now and who you were five years ago is largely due to how you’ve spent your time along the way.

The habits we groove become who we are, one minute at a time.

A small thing, repeated, is not a small thing.


No Reboot Kernel patching

Why we need patching linux kernel?

  • Kernel patches are released for a number of reasons, but fixing security holes is the most frequent reason. This is why it’s important to install the patch as soon as possible.
  • Unlike other operating systems, Linux is able to update many different parts of the system without a reboot, but the kernel is different. Every running process integrates with the kernel intimately, so switching out parts of the kernel while it is running is quite risky. So, When the kernel is updated via a patch, the system needs to reboot

“No Reboot” Kernel patching

  • On the other hand, rebooting the computer is irksome, and in some cases, where uptime is important, it can be a real issue. This is why “no reboot” kernel patching has been a priority for many administrators.
  • Some servers and critical real-time applications must not be taken down without advanced scheduling, even for a few minutes. This can be a pain when administrators need to keep the system secure and a patch is released to repair a newly discovered security hole. In this case, no-reboot patching becomes a real boon
  • Recognizing this need, Red Hat has been working on kpatch, and SUSE has been working on kGraft. Both of these programs are designed to accomplish the same task, but they take a different approach and have different strengths.
  • But this doesn’t mean that system reboots are gone forever. Even on a system with the Linux 4.0 kernel, there will be security updates that still require a reboot, because there are other non-kernel components that can require patching, and some of these require a reboot as part of the process.
