Time flies

Yes. Time flies. A week already since my last post, but I’m still dry. Well, that’s not exactly true, but I’m somehow not able to sit and write down my dreams. Like this one of a Sci-Fi sit-com, “The Adjustment Bureau”, that is not related at all with the homonymous movie, where a group of common people are sent across time to fix up little historical inconsistencies. A sort of The Office meets Doctor Who. Or maybe Stargate. Please, if you are a TV producer or a Netflix mogul, feel free to contact me to make it happen. Or that dream I had where we rent a flat together with our selves from a parallel dimension, and we start a fight over who sleeps with whom. Will you sleep with your parallel wife or husband from another dimension? Why not?

The Water Wedding needs to end soon. Now, in order to do that properly I need to really copy all the parts I have up to now, read them aloud, check for inconsistencies and go ahead with the finale. I do know how it ends now, but I did not know when I started it. Why I didn’t do it yet? It sounds funny but I work now with another laptop, and I don’t want to waste my time moving files around when my new laptop arrives. Lame excuse, I know. Then you can take this one instead: lately I’m so tired when I arrive from my working place that I don’t have time to elaborate any plot: I just want to grab a beer and watch some dumb comedy, or read a little. Maybe play with my kids. But holidays are coming. And after my holidays, I promise, you’ll have more. More of everything.

Creating a github repository on CentOS 7

I was asked to share my docker. Strange, right? Who’s interested on this sh*t? But OK, let’s share it in a professional way, via github. This is my quick howto.

1.Create a github account and a new repository. Go to github.com and sign up. I’ll assume you know how to do this. Fill it up, look for the new repository option. My repository will be called superduper.

2Make a folder for your stuff, init the repository, add all the content, commit. I make a folder superduper-local and copy there all the folders of my superduper project.Ā  To add and init, type:

me@cos7 ~/superduper-local ## > git init
Initialized empty Git repository in /here/superduper-local/.git/
me@cos7 ~/superduper-local ## > git add .
me@cos7 ~/superduper-local ## > git commit -m "Full Project"
[master (root-commit) 4a46d27] Full Project
1294 files changed, 399216 insertions(+)
create mode 100644 file1
create mode 100644 file2 
... all my files

3. Add the content to my repository, and push the changes:

me@cos7 ~/superduper-local## > 
git remote add origin 
me@cos7 ~/superduper-local## > git push -u origin master
Username for 'https://github.com': gitusername

remote: https://github.com/gitusername/superduper/pull/new/master
To https://github.com/gitusername/superduper.git
* [new branch] master -> master
Branch master set up to track remote branch master from origin.

I can check the files appear now on my github website. Now I want to edit one of the local files and commit the changes. Let’s say I edit the Readme.md . To see the changes on my github, I need to do the next:

## > nedit README.md
## > git commit -m "Updated README"
[master 57728f3] Updated README
1 file changed, 2 insertions(+), 2 deletions(-)
## > git push -u origin master

completed with 2 local objects.
To https://github.com/gitusername/superduper.git
4a46d27..57728f3 master -> master
Branch master set up to track remote branch master from origin.

And now we can check that the file on the web has been modified. Welcome to the new world of online code sharing šŸ˜›

Install Chrome on CentOS 7

This was interesting. Fruitless, but interesting. I wanted to install a new browser to test some web-app that is supposed to work only on modern browsers.Ā  Unfortunately Chrome works but not the web-thingy…so back to square zero. Anyway, as it is described on tecmint, what you need to do is :

  1. Create a google yum repository. Go to /etc/yum.repos.d/ and edit and save a file google-chrome.repo with the next:
  1. Install it:
yum install google-chrome-stable

Now, if I’m root andĀ  I want to launch it via the command line, I need to opt out the sandbox. Otherwise you get this error:

Running as root without --no-sandbox is not supported. 
See https://crbug.com/638180.

Just for your information. And for my records šŸ˜‰

Cannot install Windows 10 (error 0x80300024)

I am repurposing old DELL servers into powerful Windows 10 servers. We could buy new servers, but why should we? We don’t have the space for them, and these guys DELL PE T620, if filled up, can still give you almost top-of-the-art performance. Imagine: 192 GB of RAM, 3 GPUs, 10 GB or infiniband, plus 38 TB of storage. I can be happy with that. You can be happy with that. We do the install on a separated SSD, connected to the SATA the CD-ROM unit/DVD player is. Yes, it’s not clean, but it will allow me to replace a broken disk of the array without touching the system disk.

So I reboot and start to install W.10 on the SSD. When the installation starts, I’m given the choice of disk to install it. I see my array and my SSD, but after formatting it, I get the error on the title. What’s going on? I get a new SSD, just in case, and start anew, but again I get the error. There is a solution on the MS forum. I switch off once more the server, and remove everything but the SSD. The RAID card, the 10 GB card, the GPUs, everything. Quite a hard work, if you ask me. Then I try again, et voila!Ā I manage to select the SSD for installation. Now there only one disk available and it has the index 0 on the installation list. Before, with the RAID card in, the index 0 was corresponding to the 38 TB RAID system. RAID storage that I want as independent as possible of the OS disk.

After updating everything (through the 1 GB board NIC) I need to, once more, switch off the server and install the pieces that I previously removed, the RAID card, the 10 GB card, and the GPUs. That are now all happily recognised, and I can start playing with my Windows 10 GPU server.

The water wedding (XXX)

-Long live the Empire! – Somebody shouts. We choir. – Long live the Empire!

The parade is reaching its climax. The diverse vehicles that were composing it seem to dismantle themselves, and their pieces float around, driven by invisible strings, to rearrange immediately to create an impressive scene of several stores height. The water towers around, the pillars of our roofless temple, diminish, and some fountain start to shine with a deep blue, that a memory pushed in my conscious mind tells me it’s due to neutrino radiation. Suddenly, the fall, the Fall that is the sea flowing inland, seems to surround us, its flow diverted in a way we are in the centre of an inmensive water crater. Now, music. From where it is coming from? The scene? the walls? Meanwhile, I keep hearing the heils to the Empire, but getting softer, and softer, mixed up with soft drums and sweet, repeating, flute tones. The mixture is intoxicating. And there he/she is.

I was not expecting anything less impressive. Our Emperor comes floating above us, like ten meters over us, its silhouette amplified in the space around, like if you see several times the same person, the bigger the image, the more diffuse. Maybe he/she fell from the sky. I count up to seven holographic levels, seven mirror images like shells, surrounding him/her, the latest and more diffuse reaching the floor level. Seven. Does it mean anything? I try to focus on what’s in the centre. I can’t tell you if the Emperor is dressed or not, their contours are blurry, like when you look at somebody right after waking up or after looking at the sun with your bare eyes. But his/her face smiles. And his/her smile shines for us. When he/she looks at me, I freeze.

– Dear Court – The loud voice is not coming from an specific source. Definitely, it’s not coming from him/her. It seems to come from the water walls that are now surrounding us. – I am very GRATEFUL you decided to join us on this moment of time. Because this moment of time is of vital importance for us, therefore it is of vital importance for the EMPIRE. – Some words seem to make the ground shake, so vibrating they are. The Emperor drifts to the place where the fall was originally, where the scene was built up with the pieces of the vehicles on parade. When he/she is there, blossoming holograms cover it all, even the air around us. They resemble flowers are in all tones of blue. Or serpents. Then, they’re gone. – Amongst YOU, there is one that will unite me, will become ONE with me, and together, we will RULE the Empire, we will RULE the world. – I feel like I’m going to faint. The revelation is too much for my peasant brain. I misunderstood it all! The Emperor is going to marry here, today, right, but he/she doesn’t know his/her broom/bride! – We shall START the WEDDING.

Where’s Hakim? I can’t cope with this alone! I look around, and the other guests, like, for example, the Ministry of Something that was hitting on me, are as petrified as I am. So if they knew about this, they don’t seem to be able to show it. Hakim is lost, nowhere around. What a moment he chose to go to the toilet, I think. But why I’m not petrified? Is it the nanobots? And how about his/her servants? The ones in the parade? Are they all robots, or something like that? My voice doesn’t tell me, and I’m too scared to ask.

Small talk 2050

– Hi, how are you?
– I could be better. And you? I don’t meet you in person since…
– Yes, since my defense. When I reached level 13.
– Right. Level 13. What level are you now? 23? I could check but…
– It’s OK. It’s awkward to check it in person, I know. I’m level 20.
– Not bad. With your level, do you still need to come to work?
– I need to, but only once per week. I must say, anyway, that I like it: I meet people that are just starting, learning the methods. New followers, and new ideas. When I’m at home, I tend just to work on my project and defend…
– And how’s your life with level 20, if I may ask? I want to reach 20 at one point. Being 18 myself, it my time to carefully plan my next move.
– I don’t know if it’s general…I’m not planning to be 21 any time soon, so I don’t follow so many level 20. I do know who’s following me…as in your level, you need still to defend your work from the high level researchers, but it’s OK. It looks like my research topic is no more a hot one.
– Isn’t? Really? I can’t believe it! It was the biggest thing when you defended your 13!
– Well…there was that big battle the last semester… maybe you saw something on your feeds… when Prof. Burkistein decided to close the access to our facilities to all the people below level 15. It turned out it was a defensive move: the lab across the Atlantic released right after a revolutionary method to do the cross-checks.
– Yes I remember. I didn’t understand it all, since it’s not my battlefield, but I remember it as a very elegant solution. The type of solution that is really obvious, if you look at it from the right angle, but nobody saw before and nobody saw coming. I think most of the people on that team advanced around 5 levels thanks to it.
– Exactly. The truth is, one crawler told Prof. Burkistein in strict confidence about the coming battle. And he closed everything to avoid more information leaks and to pile up expectations. As a consequence, every search on us is filtered out, and since then, the interest on my specific topic went down by 50%.
– I see. In that case, you are less busy than before, right?
– I am. But if Prof. Burkistein doesn’t release any big impact results on this semester, probably our funding will be affected. That will mean less followers, less questions, and less new ideas. And at the end, the death.
– C’mon. Don’t be so dramaqueen. Death?
– Either that or ending up changing the topic. I may need to give up up to 10 levels to move to where you are, for example. Not that I can’t do it, but…
– I understand. I must say, what we do is pretty challenging also. And it may bring up exciting surprises soon. I can’t give you details, since we don’t know who’s hearing, but search me and make a guess! I think given your level and that you know my background, your guess may be right. And If you follow, I can accelerate your move…after all, we’ve been friends since ten years, right?
– Yes. Pity that we meet only for battles. But how about I search you and we have a coffee later today to speak about my guess? We can broadcast the discussion if you want…
– Perfect. Let’s decide if we broadcast it on the fly. 2 PM is fine?
– It’s fine. See you later then! And thank you for the offer!
– You’re welcome! See you soon!

The water wedding (XXIX)

I’m definitely not anymore completely myself at this moment, the colourful drinks and the information overflow is making me dizzy. After our arrival, magically fountains of alcohol popped out of the tables, and invisible servants placed everywhere big trays with exotic food. Or exotic for me. Giant Mussels with funny shapes. Transparent colourful little spheres, fish eggs I believe. Fried insects looking like still alive, with their open wings. Mushrooms, truffles, berries, and very delicate moon-shaped breads. Super tasty little sausages. I ate and drunk like there was no finale, while following Hakim as a cat does, looking for his approval but silent. Beautiful and smart, I hope.

Oddly enough the hall seemed to adjust itself on size according to the people coming. Now it’s as big as a football field, not that I play football, but I have the concept of that size in the way I know the Moon is not a eye in the sky that is staring at us, but a satellite. Fun fact, I seem to remember also that there were humans landing on it. I stare at one of the water spikes that act as trees on the field, partially covering a group of tables with a changing filtered sunlight. I think everything must be controlled by fields. The same fields that the Shadows are using to hide, maybe. Then, where’s the energy source? Is it the cascade itself? Yes, a waterfall can generate energy. But how they pipe it this way?

– Hakim. – He looks at me. He’s certainly sad. Maybe he was forced to live outside the Court, or maybe this celebration is bringing him back to his past. He sips from a gorgeous glass and smiles me back, waiting for my question. So I ask. – What are we going to do after this is over? – HisĀ faceĀ contorts with sadness first, then with rage, I believe.

– What do you mean after it’s over? After all that I’ve given you! Of course we’re going to come back and continue our lives. Or maybe you are not coming back… – his eyes suddenly show a dark light that I never saw before on hom. Or did I? – maybe you will choose one of these… puppets…instead of me. Do you have the guts to do something like that?

– Stop Hakim, you’re hurting me! – His grip relaxes somehow. He grabbed me at the end of his last sentence, and for a moment, I thought he was going to throw me to the floor. But he didn’t. People around us (isn’t that the Ministry of Cultural Affairs?) seem to show interest of how our fight is developing, and my lover seems to realize it.

– Sorry Kris. – He grabs another glass of something blueish, and in a second the liquid is gone down his throat. He suppresses a burp, but I see it. I know him. Or I think I know. He hesitates for a couple of seconds just to take after yet another drink, as I was expecting. – I think I’m drinking too much. I hope you will understand why later. And I’m not able to clean my system without help as before… so… will you come with me to help me to release some liquids? Or will you stay here with Mr. Important Ministry of Something? – The alluded ministry, that was following our fight with puppy eyes from the closest table, suddenly seems to be offended and leaves the table making some muffled sounds and murmuring. And I’m happy he’s gone.

– No, of course I accompany you. I wouldn’t be here without you, and you know it.

At that precise moment, instead of running one over the other, we need to turn our heads. The wedding procession starts to arrive to the hall, and the hall itself expands, it changes, tables sliding out of the central part that seems to be slowly growing up, devoid of people. We were, at this moment, two groups, one to the left, one to the right. In the middle, a wide water passage, like a low catwalk, is forming. We are very close to border of it, so good news is that I will manage to be very close to Him/Her, to our God, to our Leader, to our Emperor. I wonder if I will survive it.
