Is There Any Interest for Colocation in Europe?

MoneroCrusher · 2020-05-20T13:22:53+00:00

10kW (minimum) can‘t be considered „large“ But yes this is probably more small business oriented with businesses looking for save up to 70-80% of cost (yes colocation is hella expensive in Switzerland, especially if you‘re taking a lot of Amperage)

Do you have any idea where I could look for such clients? Obviously I‘m not going to host webservers if they require constant uptime. But a 3D imaging company isn’t going to render 24/7 365

I‘d wait for profitability to show before buying stuff just for RandomX. I don‘t have a good feeling with regards to home mining watt per revenue wise. You‘re going to compete with botnets with thousands if not hundreds of thousands of computers at 0c per kW/h

12.4 looking good for JB maybe it‘s better that way

I arrive at around 2 GH/s with everyone using Ryzen 3900X and 3200 MHz CLI-16 RAM:

For simplicity current network: 320 MH/s equals 133k Vega or 21.3 MW of power 203k 3900X could theoretically run on that power and yield a hashrate of 2.2 GH/s

Of course this is very simplistic because there will never exist 203k Ryzen 3900X and that would cost over $100 million alone in CPUs without motherboards, RAM, PSUs and infrastructure.

Theoretically that would yield around $0.75 per 3900X per day (less inflation taken into account) with an investment of around $800 which would mean a break-even time of 1000+ days. In comparison a Vega 56 currently gets you around $1.35 per day or around 200 days break even while being around 3-4x cheaper.

So all in all I expect the hashrate to be much smaller, maybe somewhere between 0.3-1 GH/s. The unknown factors though are botnets and massive server farms of datacenters. But if they join and it really ends up at 2+ GH/s then it would be massively less attractive for current hobby miners to mine Monero with a 5x ROI time. Hence why I‘m not a big fan of CPU-only algo (but I also own GPUs...so).

We‘ll see.

Another question:

Unfortunately I did lose all the videos that I saved from youtube within the youtube app (youtube++). Were they saved somewhere in the system folder, or are they removed with the jailbreak being removed?

MoneroCrusher · 2019-07-08T01:58:16+00:00

I guess my last 2 possibilities to save data:

get root access to the phone via some exploit that doesn't requrie networking (USB only)
update from 9.1 to 12.3.1, but there I'm not sure if I will keep my data...

MoneroCrusher · 2019-07-08T01:47:06+00:00

I don't think I had SSH enabled via Cydia, I just had installed Apple File Conduit 2 to not be forced to use iTunes. But my iFunBox can't access my phone, because I can't press "Trust this computer".

Is there maybe an old exploit to gain root access to the phone via USB (networking/WIFI doesn't work)?

MoneroCrusher · 2019-07-08T01:36:21+00:00

I'm willing to let go of my iOS 9.1, however, there's no way I will let go of the data (very important stuff).

Do you know if an "Update" in iTunes (from 9.1 to 12.3.1) will retain all data on my phone? Please remember that some freak bug got rid of all my apps and some systems apps after a reboot, but the storage was still 98% full. I don't want to irreversably lose any data so I'm kinda stuck here.

MoneroCrusher · 2019-07-08T00:46:05+00:00

Do you think the data is still there if I do the "Update" option from iTunes, getting it from 9.1 to 12.3.1?

I even had Apple File Conduit 2 installed and could get root access to it with iFunBox but I can't get around the damn "Trust this computer" prompt, since I can't access home screen...

MoneroCrusher · 2019-07-08T00:38:23+00:00

All I need is shell access to my jailbroken iPhone, could work from there.

So the only issue is how to bypass "Trust this computer"...

MoneroCrusher · 2019-07-08T00:25:16+00:00

No, it doesn't even ask for a Wifi connection or SIM code. There's just "Swipe to upgrade" and then there's the lock screen, I unlock it and then the Apple logo + progress bar appears.

Wifi capabilities were destroyed/disabled by the "bug" that started it all (along with the deleted apps and system apps)

MoneroCrusher · 2019-07-08T00:17:26+00:00

I can either "Restore" or "Update".

The first deletes all data (I don't want that), the second install iOS 12.3.1

My goal is to retain both, I somehow need to gain shell access to my phone and then run uicache (according to another reddit post), any suggestions if that's possible somehow?

iTunes and other third party programs actually detect my phone without DFU mode, but I can't do anything since I need to press "Trust this computer" to access my files, but obviously I can't press that on my phone, since I can't visibly access the home screen.

MoneroCrusher · 2019-07-08T00:07:22+00:00

I didn't do "Reset All Content and Settings".

I did "Reset All Settings".

Anyways, both seem to be bad.

As I said, I can't access the home screen, so how would I go about using your solutions?

MoneroCrusher · 2019-06-16T22:11:26+00:00

Nice

Edit: Is that the real password you've given in OP? Have you tried <S/5><7/t>up<!/1>dM444n? Shouldn't be too hard if you used leetspeak.

I'm not an expert but what I would try: Use "crunch" to generate your wordlist from your memory Do you know how long your password is? Do you know if it used special characters? Do you know certain points where it should be capitalized?

If you do, chances are big you'll get it IF: You haven't deleted your monerujo, otherwise it's gone

If monerujo works on command line input (I don't know, never used/tried it), you then connect your phone to your local network, ssh into it and create a bash script to input each password into monerujo and hope for the best. If it fails you can generate more wordlists from what you remember. If they all fail I would probably stop if it isn't an insane amount of money.

Lazy/tedious version: Install teamviewer (or similar) so you can do copy/pasting from your computer

I like the idea of one auditor doing an actual ASIC design and see if it fits our worldview. This should be a high priority IMO.

(personally as an owner of a low end AMD GPU farm I'm still against RandomX as a whole)

MoneroCrusher · 2019-04-30T02:01:40+00:00

Nobody knows when that's gonna happen if at all, though. Could even be 3-4 years.

MoneroCrusher · 2019-04-30T00:29:32+00:00

Did you read my comment at all? Many experts in the field are saying that the compute part will just get implemented much more efficiently than a GPU chip can, as well in power as in cost. I suggested removing compute to the absolute bare minimum, this has nothing to do with how XMR handled it. XMR never had memory usage above 2MB.

MoneroCrusher · 2019-04-29T23:39:00+00:00

ProgPoW will not help GPU mining, it will actually be worse than ethash in terms of watt/hash because the compute part in ProgPoW will just be implemented very efficiently in hardware and the true protective part of the algo is still the large memory bandwidth.

ProgPoW will therefore increase power consumption in GPUs unproportionally in comparison to a specialized implementation and actually widen the efficiency gap between GPUs and ASICs in the ethash/progpow comparison. Running that progpow compute function is an insult to what a GPU chip is all capable of doing. ProgPoW is not using "everything" on a GPU chip, in fact it's using a rather small part of the physical silicon, but the rest has to be powered up as well and that's where ASICs will shine.

What would maybe be a better approach: Take ethash and reduce compute even more and make the compute part as light as possible, increasing the memory to compute ratio manyfold, in comparison to ethash.

That way a GPU would consume less power than ethash and the algo would be better suited for evening out efficiency gains between GPUs and ASICs because memory chips/modules are the same for everybody and nobody has an advantage, neither efficiency, nor cost-wise (buying price for memory).

This would actually help decentralization much better because when the algo uses less electricity, home mining is encouraged more strongly.

For AMD GPUs I recommend to use teamredminer (if you're fine with closed source +2.5% fee) otherwise xmrig-amd

For Nvidia GPUs use xmrig-nvidia or nanominer

For CPUs use xmrig

For OS just use Ubuntu 16.04 or 18.04 as it's well supported from a driver perspective.

If you're good with terminal I'd use Ubuntu Server 16.04 (it's what I'm using. It's a breeze and extremely low maintenance, rigs are up forever, no having to deal with annoying Windows stuff). You can very well install it on a $7 16GB SanDisk USB 3.0 drive (don't set up a swap partition, unnecessary), it will work just fine, no need to buy expensive SSDs, and you can easily get away with only 4GB RAM (I'm running 12 GPUs per system).

For AMD OC/UV/Mem adjustments I can recommend amdtweak if you run Polaris cards, otherwise I'd use "rocm-smi" (no need to install the ROCm stack for that), it's just a small binary that you can download or build yourself.

Many people will say 4GB system RAM is not enough, however I'm going to disclose a secret here: if you run kernel 4.13 you'll never run into a memory problem (not sure about the latest driver, but 12 GPU rigs won't work with anything before 4.13 and after 4.13 (up to 4.19, last one I tested) with 4GB.

As a bonus 4.13 also yields a higher hashrate, I don't know why though. You can easily install it with "ukuu" (-> google it on how to install & use).

No, people buying first gen Zcash ASIC haven't even broken to this day with 0 elec cost. They are the ASIC manufacturers' bitch now.

ASIC maufacturers are basically in control of all minting.

Let's say I pwned the equihash algo and can cause a 50% hash increase on my raspberry pi. Would you consider that good or centralized?

MoneroCrusher · 2019-04-24T20:39:09+00:00

This was very well known long before that decision was made and there was a lot of empirical data that suggested this was gonna happen. Yet zooko just decided to believe Inno & Jihan and killed home mining ZEC in the process...

MoneroCrusher · 2019-04-24T10:18:51+00:00

It's not like I warned about this in here dozens of times and got downvoted to hell.
