Open letter to the CRAVE community

I write often too much, so I’ll try to keep it as short as possible.

I can fully understand DRC. Nobody cares, all the work sticks to the few devs and maintainers who are in charge. That is so, since the early times of CRAVE’s survival (when the logo was a winged skull and the claim was “embrace darkness” – I’ll come back to that topic). The people from the team suffered a lot but managed a successful coin swap, built a completely new webpage, whitepaper, roadmap, docs, and all the stuff needed for a mature coin. They drove CRAVE’s source code to new levels, managed to release several platforms supporting wallet and masternode’s which made CRAVE scalability and efficiency easily compete with other anonymity and security focussed coins in the coinmarketcap top ten.

What CRAVE is missing is a supporting community – that includes also myself, mea culpa. I thought why that is so because I really like CRAVE and bought it at approx 30 times the actual value. The reasons I finally found were that it was some experiment to run some masternode from some Dash-clone (which I CRAVE by far not longer see so cause it is better), make some investment which I hoped to pay out, and last but not least I wanted to learn. Unfortunately, I could barely support the team because of a big lack of knowledge and competence as a developer. Today I know a lot about cryptos, run a few masternodes and even CRAVE is an exot which I still support at a high loss but I really like it. And I still do so.

I the beginning when CRAVE was some underground coin with a valid code base and to the edge security and anonymity features (the “skull”-time mentioned above) I showed it to a developer who commented it with “if I show this [website] to an investor they will leave the room and I will never see them again.” So I appreciate the “makeover” and retreat from the “darkcoin” image but already at that time, I saw a loss. A loss in authenticity. for an underground coin I could accept no real names on the team page, especially as they wanted to turn CRAVE in some kind of community and/or “DAO”-drive project, but somehow the big leap forward never happened and the price for leaving the niche which was paid in loss of the member who really “embraced darkness”.

In the initial bitcointalk post some member advice not to revive CRAVE with the word to let the dead rest in peace. But it was revived. Today it is a zombie starving to its end. But I am still not willing to give up. I will try to help where I can (I am not a developer) so I try to take over some project management and organising and cheering up people who are willing to help and do something.

My roadmap is rather short as it is a short term plan to support the columns CRAVE is built on to fixed it in its actual position. Afterwards, we should go “back to the roots” and try to fill the original niche again

I. Stabilizing:
Get a new certificate for the domain – nobody will join a community communicating with a non-encrypted website. If there are any costs for hosting the site and so on I am willing to take some of the bill (maybe for a year) and/or move the site to one of my servers (or my hoster). There are some wrong links in the masternode PDF as in the installation script. I corrected it. Do I need to fork on github or somewhere to make a pull request? Please let me know. You can reach me on discord.

II. Back to the roots
First of all, why I think so: coins like Dash, Monero and other security focussed coins have success. Most of the transactions in the so-called darknet are today done with Monero. So generally the demand exists but is already satisfied. For CRAVE it should be very hard to compete with one of these big players even it has the potential for it. But it could complement the demand for high security and it could play a role as an exot providing a second security line for players who need double secured and anonymized transactions. An exot like CRAVE could first serve by “security by obscurity” and at the same time with its features like z-CRAVE doubling the anonymity.
(Simple example: I use my BTC to buy CRAVE. I make Z-CRAVE and turn them into newly minted CRAVE again. With that CRAVE I buy openly Monero, and can utilize the Monero security features, and eventually, I use Monero to buy whatever I wanted to buy securely and anonymously. So CRAVE could fill a niche as a supporting little brother of other security focussed coins or as a second frontline in obfuscation. A hidden layer behind the hidden layer. For that, you need an secure market which supports transparent and “non-hidden” addresses for BTC, XRM and CRAVE.)

As long no from coinmarketcap supported market is listing CRAVE against BTC it will be shown without information. A no-go. I did some research and found “Bisq”. Bisq is a decentralised trading app with onion/tor support and not “owned” by anyone. it has an open-source base and is DAO-driven. Also, it is mostly censorship-proof and cannot be banned. We need CRAVE to be listed there and can kill two birds with one stone. We can get CRAVE listed at coinmarketcap again and place it in a new niche. see yourself on Bisq’s website.

And for all the people who are still holding CRAVE at a high loss, we can maybe manage it to have a market to buy and sell again. At the moment I HODL CRAVE and start one MN after the other (which makes CRAVE pretty fast but is contra-productive). I already gave up on the idea to make “big money” with CRAVE but it is a too big pity to let it die.

There are two options to get CRAVE listed in Bisq.

  1. One “costs” some money as you need to convince a developer to implement CRAVE. They say it can take a long time anyway. I am convinced even with a big bounty no developer will hurry to implement CRAVE – if we can find one at all.
  2. The other option is to do the job according to their requirements on our own. It looks not that complicated (too complicated for me) and it is very good that there is already a valid block explorer and a really good codebase.

So eventually, who is onboard?

I already said I will try to help wherever I can. I am willing to support the website and to do communication and other support wherever I can. I can provide web space for the website and explorer, some work as an admin (linux), and run this or that node. Also, I can help to implement CRAVE to Bisq (or other trading platforms) if someone leads me to to do so – I have some technical understand and experience as a linux admin. Please let me know how to proceed and what you are willing to do for CRAVE.

By the way: My highest respect to DRC and all the other team members who hung on so long. You did and do a really good job! Sorry, but I was not on discord for a lone time, so maybe I make some wrong assumptions or have wrong impressions about who did what and so on… I don’t want to be involved in any dispute or discussion about “leadership” or make problems or be the reason for any problems. My only intent is to save CRAVE.

Switched to NVIDIA Quadro K620

Switched to nvidia quadro k620. After installation of fitting drivers, matching requirements of cuda10 and escape from dependency hell deep learning on the GPU seems to work. Before: 24 min on CPU, now: 6 min on GPU – fair enough! (With a batch size of 512 (instead of default 128): 4.40 min, batch of 768: 4.21 min, batch of 1024: failed.​

Intelligenz breitet sich in unserem Haushalt aus!

Ob keras zumindest künstliche Intelligenz in unseren Haushalt bringt? [挤眼] ​
7. Oktober 2019|Schlagwörter: , |0 Kommentare is an regulatory overkill in China – if you are a foreigner in China

If you are a foreigner living in China for longer time you face several problems when shopping. If you want to buy online at Taobao you have to deal with the language problem, contect sellers and ask for any conditions, warranty (at least kind of), make sure what you want to order is not a fake or knock-off, and of course shipping times – you can be sure never a good from a seller located in Shanghai with the status “in stock” really means they have it in Shanghai already.

There are also other reason which make you sooner or later abstain from Taobao and focus on international online shopping in China:

  • Adidas does not offer sneakers in an adequate size for your westerner’s feet
  • The electronics you want to buy is not available on the Chinese market (e.g. Anki Cozmo, Sabrent ds-4ssd)
  • you want to buy something which does not need help from a Chinese – maybe a gift for your wife or something which needs some more privacy

In the past was on option, but now it turned out to by so extremly over-regulated that is completely dead for foreigners in China.

If you want to order something from a foreign Country and let it ship into China you have to give it an address. If the receiver is a Chinese or not doesn’t matter for the customs a Chinese ID-Card number is required. So as a foreigner in China you have to bother a Chinese and make him/her responsible for the customs anyway. But even if you do so or you want to send a gift to your Chinese friend you will face the following problem:

You order, choose your Chinese friend or relative with Chinese ID-Card number a shipping address, and eventually you pay with your bank account or WeChat pay. Hurray! Every day you get updates and your goods are tracked and finally arrive at the Chinese customs –  until the big WTF-Moment. Amazon writes you that your goods are returened with the reason “can’t be delivered”. Well, through the disappointment the one and only question of every foreigner in China make its way to break though: Why?

Why first send out, transport by air, then return?

Again, you bother some Chinese to let Amazon call him/her (an option which is very very hidden in the returns options because Amazon gives a sh*t to inform you proactively with understandable reasons about a failed delivery). The reason is that the customs want that the payment channel used to pay some goods imported to China needs to be traceable down to the single Chinese person, who gave the ID-Crad number as the responsible person. So the goods needed to be payed with his/her bank account OR at WeChat-Pay the payment must be connected with that ID-Card.

This makes it of course unusable to send the stuff as a gift. I also see not the slightliest reason why they don’t check that in advance instead of shipping good through half of the world only to return them.

I say it as it is: SUCKS!

… and never expect that you can contact Amazon directly or that they have a customer service which deserves that name. I guess if they had then at least 10% of China’s inhabitants were needed to work for amazon to explain disappointed customers why their orders fail. The other way round it makes by far more sense for Amazon to make money by let Chinese sellers sell every F**K on their platform to other countries.

PHP-Modul/Extension mcrypt in php7.1 und php7.2 wieder verfügbar machen

  • 1.647

Mit PHP 7.x wird die Erweiterung/das Modult mcrypt nicht mehr als fertiges Paket für Debian, Ubuntu, angeboten. Der Support von PHP 5.x ist außerdem bereits ausgelaufen, wodurch eine Umstellung auf die neueren Versionen 7.1 bzw. 7.2 notwendig wird. Doch es gibt sehr viele PHP-basierte Anwendungen, die zwar mit PHP 7er-Versionen kompatibel sind, aber die einbindung von mcrypt weiterhin voraussetzen.

Nachfolgend eine einfache Anleitung, wie unter Ubuntu 18.04 LTS die mcrypt als Modul wieder bereitstellen kann.

apt-get install php7.2-dev
apt-get -y install libmcrypt-dev
pecl channel-update
pecl install mcrypt-1.0.1
bash -c "echo extension=/usr/lib/php/20170718/ > /etc/php/7.2/cli/conf.d/mcrypt.ini"
bash -c "echo extension=/usr/lib/php/20170718/ > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

Jetzt mal schnell prüfen:

[email protected]:~$php -i | grep mcrypt
Registered Stream Filters => zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

Natürlich kann man die PHP-Extension auch über die php.ini einbinden:

How to strip down and upgrade your Synology DS218+ to 16 GB RAM

If you follow the instructions below you will abandon your warranty. Due to the fact I feel like a tinkerer, I see the warranty seal anyway as some kind of trophy – with it comes a Synology DS218+ 2 Bay DiskStation NAS (Diskless) with a Celeron CPU (DUAL Core, supporting AES acceleration), hot-swap capable HDDs, RAID5-Level and eventually phat 16 GB RAM.

As factory default, the DS218+ is equipped with 2 GB RAM and with 2, 4, or 8 GB additional RAM in the empty slot you can upgrade it to 4, 6, or 10 GB. But that’s not the end of the road. With some skills and guts, you can upgrade it to 16 GB, because each RAM channel can handle up to 8 GB memory. But the apples at Synology’s trees hang high. They covered the first memory slot with a metal case (feel free to play a disappointing fanfare of your choice at this point. I’ll take the one fro the 80th arcade game Pitfall).

So below you can see a rough description of how to upgrade your DS218+ to reach the full capacity of memory and make it a NAS mo-mo-monster MACHINE!

That’s a machine able to serve as by far more than a file server, media player, streaming machine, and network storage – this one natively runs docker containers and with 16 GB RAM extension (my choice: Crucial CT2KIT102464BF160B 16GB (8GB x 2) Speicher Kit (DDR3L, 1600 MT/s, PC3L-12800, SODIMM, 204-Pin)) can also provide some developer environment and a wheelbarrow more of services. Grant yourself the Christmas present you really like and which you can work on if the kids are in bed.

Update in the very last minute

Between picture 8 and 9 is an important step missing. Before you can remove the motherboard from the lower plastic case you need the spudgers again. Try to open the spot between the front USB-port and the case. You need to lift the motherboard some then it should slip into your hand. Be careful not to damage the motherboard or any components on it!
