New Kakao is coming…


I actually did not solved the problem in kakao. So… I decided to redevelop it from zero.


Well… Current system is running in a language and database I’m not used to. I’m not a developer/programmer what make things even more complicated to me.

When I put Kakao to run I imagined that someday this day would arrive, because of that I have more or less the whole thing in my mind. Now it’s just a matter of time to make it work.

I started this week and database is halfway done. Which means backend is halfway done!

Features and layout will be almost the same, but I’m planning to create also a signature you could use in forums.

More info will find here.


Kakao down for maintenance


I just started to backup the server to reinstall it in the SSD. It’ll still be accessible until the physical shutdown.

As you might have noticed, it’s not updating since 25/06 7:30. I found out the problem already, but still no clue where to start to fix it. Actually I’m hoping that new installation will fix it! 🙂

Also, now I found out the first server problem that is the reason why it’s at my home now. For some reason I absolutely don’t know why, it get REALLY slow when connected to a gigabit network.

I found this out while connecting it to a gigabit switch instead of directly connected to my router to do the backup… Would be faster, of course… Now it’ll take sometime. Hopefully it’ll be fixed with fresh install. Otherwise I’ll try an Intel NIC instead of this crappy Realtek.

Not that I actually need a gigabit network, even ISP only provides 20mbps and traffic is far below that, but since the server is hosted somewhere else for free, I don’t wish to get them trouble always reminding I need a 100mbps port instead.

I’ll take a shower now and pour some coffee hoping backup finish soon.

Keep you posted.

EDIT: Updates here!

Back on track!


I got the server home today to check and replace old HDs for SSD, but since SSD haven’t arrived yet, I started up the server anyway to see what’s going on.

The city I live has a high humidity level and it’s quite common to screw memory cooper contacts. Even before starting up the server, I took memories off and cleaned.

Guess what? Server is back already!

But I’ve never seen this situation happening so fast, so I’m blaming the exhaust cooler that stopped working by end of April. Who knows?

Anyway, since I bought the SSD I’m still planning to replace. One of my friends wants to buy it, but I’m a little bit afraid of this 10 years old Samsung HDDs.

Keep you posted!

Server issue!

Hi there!

Something is wrong with the server. Two days ago it went down for no reason and wasn’t starting up again.

Yesterday I went to the office and it came back to live for no reason, once more.

But since it came back it f*cking slow! I can barely connect via SSH to it…

So, you’ll notice some big instabilities for the next days and I’ll probably will buy (help me if you can) a SSD to replace old SATA2 Samsung 500GB hard drives.

It means I’ll need to reinstall the whole operating system from scratch, restore database, web server configs… Might take a while!

I’ll keep you posted.


Latest news!

Hi everyone!

I’ve been away from here for a few time. You might have noticed a few times server was down without any news!

Well… Few things happened! One of the times we were reassembling the server in its rack. It took us the whole day!

Another time was a crazy switch that screwed the network. Few days later the trainee did a factory reset in the router, as he was supposed to do that in the wireless router not “in the router”.

But the biggest issue I’m facing now is the server’s NIC. If you read earlier posts, you already know that it’s a nVidia NIC. I had one in one gamer PC I had years ago… No problem at all!

Problem is on Linux driver. Firstly you need some parameters to start up the NIC properly and I was thinking this was the only issue.

Turns out that there’s another bigger issue in this driver. After a link down, network is not coming back again. If you unplug and plug the network cable it won’t go back. You need to manually restart your network (or the whole server, if you’re the trainee without root’s password). Weirdly the leds in the switch and NIC are blinking, but in syslog you can only see “link down” and never a link up.

I was digging Google for some clues, but I couldn’t find anything related and I was pretty surprised for a while. Later it came to my mind that probably 99.9% of this NICs are running on desktops. It means they start up the computer in the morning and shutdown in the same day. They don’t probably won’t be up and running during a switch failure or some disconnect. Even if they are, it’s not a big deal to reboot the system.

Probably I could dig more for a solution, but lately I’m so busy with my job that I’m barely having time to call my friend and tell him everything is down. Luckily it’s stable for past few weeks.

And most important is: does it worth? I mean… The cheapest NIC will do the job and it takes like 5 minutes to fit it in the slot.

That’s the plan for the future! I have no clue when it’s happening, since I’m traveling week after week and the most optimistic forecast is that I’ll be free in 2 months maybe.

Another plan is to move blog and forum to domain. But let’s see!


Aaaand it’s back!


The power maintenance took almost exactly what they promised.

Exception is that the server decided not to wake up this time. To make things even better, today is holiday here, so there was no one in the office to check what’s going on.

I asked my friend to go there and only now he was able to do so.. But it’s back!

Later on I’ll go back to work in the migration!


Kakao might go down today!


Just got the news that the building where server is hosted will have an electric maintenance for the whole day. From 9:00 to 18:30 GMT-3.

It should be down already… Maybe the no-breaks are running yet. Or maybe it won’t go down.

Migration isn’t finished yet, and with this news won’t finish today. Especially because I decided to go to the track practice in my go-kart.

Talk to you later! 🙂

New server is (almost) ready!


I finally got some money and bought a brand new equipment.

Firstly I bought a MB that supports DDR3 and the old Core2Duo, but I couldn’t find any 4GB cards with 16 chips on it, then I returned.

So… I bought an ASRock N68-XXX-XXX (I don’t really remember the model) with a AMD FX-4300 on it plus 8GB DDR3-1600. I know it’s not the best it could be, but it’ll handle the database and webserver nicely.

Actually I bought it last week, but it took me couple of hours to make nVidia’s NIC to work on Linux (I’ll post later how I did it). Also I did few benchmarks in a few HDD’s I have. Finally when I choose the HDD’s and installed the OS, somehow it was pretty slow in Linux software RAID, what makes me move to MB RAID. Yeah.. I know it’s “fake RAID”, but I don’t care as long as it does what I need.

Right now I’m moving the backup from old to new server. This might take a while since old server has a 100mbps NIC. While doing this I’ll configure the rest.

Idea is that until the end of the day it’ll be moved totally. If you notice the website is down, probably is being migrated.

Came back later with news!


News on the server


I finally find out a new motherboard to replace the one in the server. As soon as it arrives I’ll replace it.

Unlike the current one, this one runs with DDR3 memory and SATA 3. CPU will remain the same Core2Duo E8400. But now with faster memory and faster access to HDD (that I might replace for a SSD, if money allow me).

This means faster update time and probably faster loading of pages. Now it’s taking from 15 to 20 minutes depending on web traffic. Also I’ll put a 2TB HDD for backups.

My friend (from the office server is now) also gave me a bigger case for it. Now it’ll get cooler (currently running on 60 to 90°C) and probably even faster.

Keep you posted.
