006 will retire in August, if you can't be ready around that time, you better go for 007.

Does anyone know when they will retire Wunderlist?

I use Wunderlist. Could you explain what makes this better than Wunderlist?

I don't know, never used it. I'm a Wunderlist user too and I'm filling I need to find some peace of software to replace the Wunderlist before it's gone. Currently looking at Nextcloud.

Thank you for sharing. Please add S1avin

Also, sort of useful thing against no-brainier-copy-paste of sudo-level-commands.

Read-Only Fridays

Never make any significant changes before the weekend. Why should be obvious.

Backups for Servers

First learn what the current procedure is for your company. If they don't exist, create them. Configure an automated backup then testing procedure, preferably with a way to contact you if it fails.


Automate as much as you can reasonably automate, but only when it's reasonably safe to do so, based on your experience (which is currently none so take it very slow).

New user being added to the various systems you maintain? You should have a script that does this after you give it their information. Even better if you can tie this to have it take the information from the HR system so you do nothing. Still have it contact you with its status if possible.

Remember, your time is money. Not just the company's money either. Time you have to learn new things on-the-job increases your value as an employee and adds to your personal skill-set (a personal value, I guess).


Some people swear by specific ones, but it's all about use case. Users should use simpler to use distros like Ubuntu while servers should use whatever makes them most secure and easiest to manage (in that order). Other than those two considerations, choices are subjective and personal.

Don't be afraid to ask questions of your co-workers

The world of administration and technology is very vast and nobody can really know everything about everything. There are no stupid questions and you'll probably be absorbing a ton of information your first few weeks working (if your management is any level of quality greater than NaN). Sometimes you may have the solution to the problem they solved by doing a thing in an esoteric way.

Have fun

Don't forget to do it. Burn-out is a very real thing. Nobody likes to hate their job and work-life balance is healthy.

Have no IT solution here, but I suggest you to burn it down before it get you...

I taught hundreds of kids how to code in the last few years and Scratch is a great way to start.

You can learn the basic concepts very quickly and in my experience it's helpful that you can focus on the logic and don't have to care to get every bracket right etc.

Once they are hooked and know how to use variables, if-else, loops etc I go on to the real stuff like Python or C#.

I firmly disagree with the people who say it's just for younger folks. It's limited, but as a starting point it is very useful. I even use it with 16 year old beginners.

In your opinion at what age is the best time to start with scrach?


Boson practice exam on linux

Hi! Did anyone try to run it on Linux? Not in VM, but in Wine? My wine is able to run every .exe file in Boson folder (like update, clean, etc), but not the exam exe file. Looks dead simple, but I didn't get why it doesn't work...

Do you, guys, have any such experience?

Heh, didn't want to be mean. I thought about autocorrection. My phone usually struggling with this word.

S1avin, thanks

Have the same issue with mine 12-bay sypermicro. ESXI host won't boot if there is 12 drives, and works just fine with 11 of them. But as soon as I had 4x1TB drives with a lot hours on them for disposal staff, I just threw away one of them. Sounds lazy, I know, but they really got a lot hours on them any way. TLDR: Same issue here, can't help, sorry.


Please, help me understand FreeNAS VM error message.

Hello, all! I have a FreeNAS VM (at ESXI 6.5-U1) with a HBA card passed through. After recent update (11.1-U1) it gave me an error message:

Is it a bad controller, some VM trouble? At least where should I dig? Which logs should I check?

Edit: formatting.

Thanks for reply. Can't do it. It's already "Thick provisioned, lazily zeroed", and it is SSD. So, SSD goes bad? I've got 6 more VM on this SSD (Linux and Win) non of them says that it's bad, tho.

Yes, sure, it will work.

Yes, it is ratioless, for sure.

Brazil blog. Anyway, thank you for sharing, Google translator work well with it.

I believe it's ok. I run it on pi only because my host with pihole VM had been down a couple times when I was at work, so the whole house had been without Ethernet. Then I decided to move it on pi and forget about such issue. )

Hi, this could be helpful: go to web client, storage - copy a folder of a VM and paste it with a different name. Than you can register new VM using new folder as a source. When you will start the new VM it will ask you did you copy or move the original VM, pick copy and that's it, I believe.

Original Poster2 points · 6 months ago

I can't seem to paste it with a different name- only option is to select the target data store...

Create a folder with a different name, go inside folder with your VM, copy all (item by item) in the created folder.

Is it because it could take only 4 x 2tb drives? Sort of BIOS issue, right? If you want more you need to get HBA or raid card. Tell me if I'm wrong.

Yes, you can. A server is just another PC actually.
