10 hours video - How I made the loop

Here's how I made my 10hrs loop video of the 1st photographed black hole in a 3D reconstruction. 4K video format.

For first I downloaded the whole video in which it was inserted, then precisely cut from start of the rotation cycle to the end, counting the frames between movements of the coordinates arrows on the left (3). I then exported 3 segments in VP9 codec, respectively with a fade-in, clean and fade out.

so I calculated how much time to get 10 hours having the single video segment duration and build a list up. It is 4697 minus 2, start and end. ``` for i in {1..4695}; do     printf "file '%s'\n" short.mkv >> list.txt;     done ``` so added start.mkv and end.mkv to the list. For the audio I searched for long music in CC-BY on FreeMusicArchive and on Kevin MacLeod's website and assembled in Audacity in order to get roughly 10 hrs. Exported in *.flac and converted in *.opus (Doing in-software resulted in a failure, not sure why): `ffmpeg -i audio.flac -c:a libopus -b:a 96k audio.opus` uploaded e.thing to the GCP server (8.6 MiB video + 435.4 MiB audio), where I installed ffmpeg and initialized a simple vnc server where I started Xorg and proceeded to assemble everything up: `ffmpeg -f concat -i list.txt -i audio.opus -c copy output.mkv` So I fired a Firefox instance up and uploaded the whole (~15 GiB) in 1 minute or 2. That's all =) I figured then out that I could have used the YouTube API someway in order to upload without the Xserver running but, well.. maybe next time I'll give it a try ^^ As usual, if you found this blog/guide interesting/useful, I am very coffee addicted ^-^ Cheers, FraYoshi. → http://bit.ly/2DtcNWq

How I rescued my ZeroNet account

I started playing with my key files in order to encrypt and secure them, I don't want my ZeroNet account to fall in malevolent hands and I'm mainly referring to those of a thief. I decrypted my keys into a folder and then sym-linked to zeronet/data so I started using the platform as usual without hassles... But starting from the second time I activated the service, after a reboot and forgot the first time to un-encrypt, something started to go wrong... indeed, I was unable to like stuff, comment and act as usual getting errors like this one directly on the GUI: Internal error: Exception: Invalid content.json file immediately followed by: WebSocket handleRequest error: Exception: Invalid content.json file: data/users/(my auth_address)/data.json in UiWebsocket.py line 83 > UiWebsocket.py line 267 > MergerSitePlugin.py line 203 > MergerSitePlugin.py line 197 > UiWebsocket.py line 484 > MergerSitePlugin.py line 200 > MergerSitePlugin.py line 197 > UiWebsocketPlugin.py line 36 > UiWebsocket.py line 431 and I've found just now watching at the logs on the CLI, this: Json merged-ZeroMe/(KaffieHub address)/data/users/(14ytAKDfNjArMTqGecTi7ginG3aZTsRAum)/content.json load error: DatabaseError: database disk image is malformed in SiteStorage.py line 299 > ContentFilterPlugin.py line 167 > SiteStorage.py line 90 > SiteStorage.py line 82 > Db.py line 166 > Db.py line 132 > Db.py line 65 > Db.py line 139 > DbCursor.py line 90 I've been a couple of days off because of this inability to operate as myself... I've tried to double check permissions, substituted keys with the previous ones from the backups, took searches, updated ZeroNet... until I remember that my ZeroNet data folder was on the periodic scheduler of snapper, so I just run the command btrfs -c (name of the config) undochange (oldsnapshot)..0 and everything came back to normal :) So I must thank Open Suse's snapper software for the success of my rescue mission! : ) This is how I've been able to handle the casualty! ^^ and I suggest you doing snapshots too, sometime unexpected things occur and these are a life saver :3 Oh... and in the meantime, I big failed in my attempt to save the blog draft and published as an empty post instead! as "leftside" let me notice XD

just, I can't recall hitting the Sign & Publish button, uhm... part of my odd experience? who knows :) Ever happened something similar to any of you? Have you wrote a blog about? If you did, I'd love to read about your experience and how you solved it! ^^

Sketching on the waiting room

I've been taught that drawing requires practice, so I started sketching what I was seeing on a waiting room :) legs were my first start, then I've been called on the phone and I continued drawing the table switching to my left hand ^^ I then realized that starting to draw I should probably train my left hand together with my right one ^^ did u ever? which hand do u use? is it the same main one that you use for all the rest? :3

Wikipedia obscured in Italy for 5th July.

Wikipedia Italia decided to self-obscure because of the European's articles 11 and 13.

Here the translation of the thing: Dear reader, On 5 July 2018, the European Parliament will decide whether to speed up the approval of the copyright directive. This directive, if promulgated, will significantly limit the freedom of the Internet. Instead of updating the copyright laws in Europe to promote everyone's participation in the information society, it threatens online freedom and creates obstacles to accessing the Net by imposing new barriers, filters, and restrictions. If the proposal is approved, it may be impossible to share a newspaper article on social networks or find it on a search engine. Wikipedia itself could risk closing. The proposal has already met with the firm disapproval of over 70 computer scientists, including web creator Tim Berners-Lee, 169 academics, 145 organizations working in the fields of human rights, freedom of the press, scientific research and the computer industry and the Wikimedia Foundation. For these reasons, the Italian Wikipedia community has decided to obscure all encyclopedia pages. We want to continue to offer a free, open, collaborative encyclopedia with verifiable content. We therefore ask all Members of the European Parliament to reject the current text of the directive and to reopen the debate by examining the many proposals of the Wikimedia associations, starting with the abolition of Articles 11 and 13, as well as the extension of the freedom of panorama to the whole EU and the protection of the public domain.

IPFS error "flatfs: too many open files"

If you have followed my previous tutorial on how to batch import your pinned files, you could have easily incurred on this "flatfs: too many open files" error. Here a practical solution for your Linux OS: Enter the following folder as superuser via your editor of preference, I'm using nano:

sudo nano /etc/security/limits.conf

add these 2 lines at the end of the file:      . . .      *     hard     nofile     4096      *    soft      nofile     40960      # End of file

Log out and log in again > retry =) 4096 and 40960 should be enough, just in case you can always augment these values! ^^

Thank You for reading!

TUTORIAL IPFS - retrieving pins' hash and batch importing

Let's say that you have some pinned files on your IPFS node but also no idea of their hash. You can retrieve the list of files by executing this simple command:

ipfs pin ls

but far too many hashes will be printed out! at this point you start saying yourself something like: "there must be a better way!" and indeed there is:

ipfs pin ls --t=recursive

okay, now you want to send all these hashes to someone, save them on your hashbook, send them to someone... but all these lines have a part that is, well repetitive! So you want to cut that "recursive" text out! So, supposing you are on Linux like me and you are using bash, this will serve you well!

ipfs pin ls --t=recursive | sed 's/ recursive//'

and this will save the output to an easily shareable file:

ipfs pin ls --t=recursive | sed 's/ recursive//' > my_pins_collection.txt

perfect! But let's say that you have thousands of pins! having this file you surely can run ipfs pin add but it will take you, well... too much, better spendable, time! so here this while loop will help you to pin all the files on the file you just created:

while read hashline; do ipfs pin add "$hashline"; done < my_pins_collection.txt

and that's all! Now your pins are importing on your friend's computer, on your backup server, on your colleague's work folder... anyway it is destinated!

HAPPY SHARING! ;D

Gimp 2.8 → 2.10. Upgrade time!

I think It's time to move on u.u # pacman -R gimp (2.8) flatpak install https://ift.tt/2CC3SAj (2.10) really.. Gimp is no longer the same from this update ^^ now It has a more professional look and smells a little bit like photoshop =]

https://www.gimp.org/release-notes/gimp-2.10.html The strange thing is that the arch repo is SO OUTDATED on this packet.. anybody knows why? Maybe because of the flatpak adoption? the source code is still available, uhm... image copied from the official gimp website: https://ift.tt/2r667qb → https://ift.tt/2IvXOi7

Decentralization Server Usage Graph 04-09 to 05-09

Usage graph for the deployed server in NYC. Actually relocating unused resources from the IPFS to the sheepit-it renderfarm.

Every server runs an IPFS node. Consider donations in order to help me to deploy more servers in more locations =] or also, run your own node! That would be very appreciated too! I don't actually know the amount of time I will have the chance to keep the node active but for now: Total number of active servers: 1 --- Eventually, some tip options ^^ https://paypal.me/FrancescoGobbo  https://www.patreon.com/FraYoshi BTC address: 1KixBphQmdymQti9VUjxDYRcHRuWr1mVQX ETH address: 0x1d88FF5F3f0768664b54659A50fcd406F4C05eF9 → https://ift.tt/2Ir5sdv
