Mining Madness

As DASH-Mining becomes more and more unrentable (New ASIC-Miners, growing difficulty see screens above), I was looking for alternatives.

Dash GPU-Mining in September 2017:

Hashflare 25 MH/s:

Dash Mining is not interessting for me anymore (dont want to buy expensive mining hw at this time).

Currently the only rentable Cryptocurrency for mining seem to be Monero. Also because it is more rentable to use CPU-Miners (in comparism to other Cryptocurrencies).


Not beeing forced to use GPU Miners (with AMD GPUs) to get coins is a big plus. I installed some miners on Linux-Systems (also virtualized). I poolmined (monerohash.com) for a few days with   5 CPU Miners. Here some results:

Physical System (CPU Intel Core Duo using 3 threads): 23.95 H/s at diff 5000
Virtual Machine(Host CPU: XEON X5560 @2,8 GHz, linux guest using 4vcpus): 61.81 H/s at diff 5000
Virtual Machine(Host CPU: XEON X5540 @2,53 GHz, linux guest using 4vcpus):  68.49 H/s at diff 6629.01
Physical System (Windows Machine with XEON E5-2609 @2,4Ghz, using 3 threads): 88,8 H/s diff 5000

ive not done tuning and tests. The VMS/Servers are still usable because not all threads/core are used.

Total Hash rate vary between 180 and 400 H/sec. So ~0.01 Monero/day is currently a possible earning. If you dont pay 4 power let it run a few days as 1 Monero is currently worth ~80$.

I’ve read a blog describing mining Monero with Raspberry PIs, i really doubt that this cpu is strong enough to have a good Hashrate… (maybe 5-10 H/s)

For testing i added a GPU Miner and achieved up to 1,2 KH/sec. So yes.. GPU mining generates 10 times more Hash…

Physical System (Intel Core i7 / VTX3D Radeon R9 390, 8GB GDDR5 with wolf-xmr-miner-v0.4): ~600 H/s

 

Here’s a small howto 4 ubuntu:

  • Download CPU-Mining software for Linux here: https://github.com/fireice-uk/xmr-stak-cpu/releases
  • Debian/Ubuntu: apt-get install libcurl4-openssl-dev pkg-config automake autotools-dev automake build-essential
  • Unzip the Mining software and run autogen.sh
  • CFLAGS=“-march=native“ ./configure –disable-aes-ni
    (or if your cpu supports aes use: CFLAGS=“-march=native“ ./configure)
  • make
  • make install
  • run the miner via
    minerd -a cryptonight -o stratum+tcp://monerohash.com:3333 -u 43dNQfaUGzbPCaa1rkW4z5H7aN5M27rLhaodZULXTtPbN7XMQxixzPC6ouB6F6NWxLSkMQ4QhTo8VhKRiBh1E9AZKudNxSv -p x
    (you have to use your wallet id, if you want to leave the session start the miner with nohup command.

MS SQL 2016 – Mirroring Error 927

I had to impelement a MSSQL-Server 2016 with asynchronous mirroring.

So I followed every step written in several tutorials (like Restoring with NORECOVERY before Mirroring etc.). It seem that sthg was missing because I always got the Error 927 which means cannot access database because it gets restored… Seems logic but for Mirroring-Setup Database have to be in NORECOVERY State (means its not accessible and state is „restoring“).

 

After several days of re-installing, researching i finally solved it, with installing Microsoft SQL Management Studio 2014. I did the same as before and it worked without a problem.

The MSSQL 2014 Management Studio Installation should be here https://www.microsoft.com/de-DE/download/details.aspx?id=42299

Making money with youtube

Last year I decided to make an experiment with youtube. I wanted to check out if I was able to earn money with it and get some values regarding how many views/clicks are neccessary to get some money.

To do so your youtube account have to qualify for monetarization / Youtube Partner Program.

Your channel have to have at least 10.000 views to qualify for this.

After activation of the monetarization program you have also to create a AdSense Account and link it with your Youtube account. After this you need to enable monetarization for your videos and hope for some clicks. If you reach 70€ they pay:

After this experiment I can say in 2017 – 200.000 monetarized views on your videos generates about 80€

Installing WinXP on newer Hardware (BSOD 0x00000007B)

Recently a friend of mine failed on installing Windows XP on a „newer“ Hardware and recieved an BSOD (Bluescreen) with Error Code *** STOP: 0x00000007B (0XF780254, 0xC0000014, 0x00000000, 0x00000000)

To solve this problem get in to BIOS – Settings (System Setup, BIOS, UEFI, press F2, F10 on startup or check out the info for shortkey accessing System Settings on Startup. Inside this Settings-Menu access SATA-Configuration/Disk Configuration

(this image can differ depending on manufacturer)

It is necessary to switch to „IDE“ in SATA-Config so that Windows XP can recognize the Disk.

Mining Dash

After a first try of mining Ethereum, which took a long time even to download the 11 Gig Blockchain File I switched to DASH which has only a 3GB File.

I used dashminer 2.1 .1:

and mined a few days with a poor result of 0.01 Dash… Seem to be only efficient when using multiple GPUs or a Mining Rig

And power has to be for free.

My Mining Hardware was:
– Intel Core i7 i950 4x 3,3 GhZ,  16 GB Ram,
– VTX3D Radeon R9 390, 8GB GDDR5

Here is my DASH – wallet, just in case you want to send me some  😉

Lets see what the cryptocurrency hype will bring.

Interesting Quotes

„I see in the near future a crisis approaching that unnerves me and causes me to tremble for the safety of my country. . . . corporations have been enthroned and an era of corruption in high places will follow, and the money power of the country will endeavor to prolong its reign by working upon the prejudices of the people until all wealth is aggregated in a few hands and the Republic is destroyed.“
Abraham Lincoln, Nov. 21, 1864

„It is beyond a doubt that all our knowledge begins with experience.“
Immanuel Kant

„Enlightenment is man’s emergence from his self-imposed immaturity.“
Immanuel Kant

„The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.“
Bertrand Russel

„We don’t want to live under a world government of the corporations, by the corporations, and for the corporations.“
Dr. Robert Bowman

Database VIM_VCDB full

If you’re still running a VMWare Version < 6 you might know that VMWare is using a SQL-Express Database for its Management. This Express Edition has limits and if they are reached, nothing will work (inside VMWare Managment).

To purge the database (which runs into the License Limit…) do the following:

  • start SQL-Management Studio to access the database
  • Select top 200 rows for the dbo.VPX.Parameter table
  • Edit the Values of Event.MaxAge to 30, MaxAgeEnabled to true
  • Edit the Values Task.maxAge to 30 and task.MaxAgeEnabled to true
  • Last step is to run the stored procedure: dbo.cleanup_events_task_proc
  • Wait… this can take a while….

Since VMWare 6.0 they switched to Postgres Database, but afaik they still need a MS SQL-Database for the VMWare-Update Manager…

Endless Space 2 – Final(ly) release(d)

Endless Space 2 is out of Early Access/Alpha Stage, it was released on 19th May with a new Fraction (Unfallen). Gameplay did not really changed from the latest versions in Alpha stage and some promised Features were not released (e.g. Fighters for Carriers). Also some of the explosions in Combat view still looks buggy (ship disappears). I’m cautious if this will get fixed (and features will get implemented) with patches… or if they will make an addon($-))…

How to kill a VM (VMWare)

If a virtual machine on your Host doesnt respond and you cannot kill/power it off, KILL it:

  • enable SSH on the ESX-Host
  • Connect via SSH to the ESX-Host
  • Enter the command „esxcli vm process list“ and note the World-ID of the unsresponsive VM
  • With this World-ID you can kill the process of the Virtual machine: esxcli vm process kill –type=soft –world-id 1077499
  • If it doesnt get killed soft, try it with hard or force
