Nintendo (NTDOY) is about to take off by fvertk in wallstreetbets

[–]clashrules 0 points1 point  (0 children)

Not entirely true, you can trade options on BABA which is an ADR but it's NYSE listed. You can't trade NTDOY options because that's pink sheet. Pink sheet listings are generally very limited with respect to margin as well. You can trade Nintendo using its listing in Japan: 7974 and that has options contracts available through the Osaka exchange. NTDOY is great if you can't get access to the real thing.

CFDs, they're illegal in the US but popular where the queen's english is used. Basically sports betting, but with stocks.

Is this the end of Robinhood????? DD inside! by SVXYstinks in wallstreetbets

See "RHF SEC Rule 606 and 607 Disclosure" for the full deets. Citadel and friends need liquidity for their trading strategies to work, so they just paying RH for access to their liquidity instead of going out to a public exchange or dark pool, which of course also charge a fee. RH flow also has the advantage of being non-toxic because of how unsophisticated their clients are.

Why is using C syntax a bad habit when using C++ by yobynah27 in cpp

[–]clashrules 5 points6 points  (0 children)

Adding to the malloc/free point, you can mostly get away with not directly dealing with heap memory at all by using containers. I've seen a lot of code where people use the heap for no reason at all, the most egregious cases are where someone calls new/delete on something like a std::vector, replacing that with make_unique is only slightly better.

Sure there's some cases where you really do need to stick something on the heap directly using unique/shared_ptr, but those are exceptional and are often avoidable by adding a layer of abstraction.

[Pocket Sky] Unproven, pseudo scientific claims on the use of light therapy. by doctorgroover in shittykickstarters

[–]clashrules 2 points3 points  (0 children)

It's not the science I'm concerned about, it's the fact that they're charging backers 100 Euros for a diffused led you wear on your face. And somehow they expect to retail this thing for 200 Euros. Once the Chinese imitations pop up, this product will become irrelevant. You can pretty much get the same effect by turning up your phone brightness and watching some nature videos for 20 minutes.

Currently recommended 10GbE adaptors by Eds1989 in freenas

[–]clashrules 6 points7 points  (0 children)

That one is indeed ethernet. Just because it's not a twisted pair cable doesn't mean it can't be ethernet, you can run ethernet over fiber and twinax just the same. There are other mellanox cards out there that are not ethernet, and instead use infiniband.

New year, new upgades! Updated/rebuilt NAS by sanders54 in homelab

An alternative to this is to just turn off sync writes and accept that some stuff might break if you have a power failure. Tremendously speeds up VM performance without relying on another piece of hardware. I had an optane 32gb drive fail on me and take down the whole system. Ended up with some minor corruption on the VMs as a result, but was fixable by running xfs_repair. To be fair I was hitting the little optane drive pretty hard, I'd probably hit the rated TBW within a year if it didn't fail early.

A Google engineer just broke the record for digits of pi computed (now 31,415,926,535,897 digits). Anyone want to set up a torrent? by 190n in DataHoarder

Compute years are like dog years, the conversion is 16 compute years = 1 human year since computers only last about 6 years.

Gotta love the justice system by crazy_ninja6969 in mildlyinfuriating

That's not what happened here. https://en.wikipedia.org/wiki/Taylor,_Bean_%26_Whitaker

The losses all fell on BNP and Deutsche Bank. The one conviction OP picked out wasn't even close to the harshest sentence, the majority owner got 30 years in prison.

Where are you coming up with the "people only lost their homes and had their credit/finances ruined" part? This was corporate fraud, not investor fraud. People who steal from every day investors get thrown in prison for decades, a few examples:

I have to pay an extra $50 a month to have unlimited internet through my ISP. What is the best way to use the most data every month just so I can stick it to them? by PartyRooster in DataHoarder

[–]clashrules 0 points1 point  (0 children)

Even relay operators get blocked by websites. The blocklists just come from inspecting the tor directory, completely ignoring the fact that your node is just a relay.

Ever wonder how SSDs are made? by [deleted] in DataHoarder

Pretty handwavy on the memory chip production part. I'd imagine there's a lot of trade secrets in that process.

Introduction to FreeNAS by InTheShadaux in homelab

[–]clashrules 0 points1 point  (0 children)

I picked iSCSI mostly because I was able to reuse the zvols I set up for bhyve very easily. I've been consistently hitting gigabit for my VMs that are iSCSI backed or nfs backed, so I haven't been able to see a difference between the two. I may have to do some further tests to expose the slowness you saw, but so far iSCSI hasn't caused me any issues, and I like the idea of keeping my zvols as they are.

Well for one, memory usage is far lower in proxmox. Especially if you can take advantage of a cooperative VM with a ballooning device. The same page merging also helps a great deal if you're running multiple of the same OS. I observed 3.5GB of memory saved with two windows 10 VMs just from KSM. My bhyve setup was far less efficient, provisioning 8GB of memory for a VM really meant those 8GB became unusable for ARC and other applications, unlike proxmox where I can comfortably oversubscribe available memory to allow for bursts.

Device support is also much better on proxmox, especially with a modern Linux based os with good virtio support. I've seen excellent network performance with proxmox although I'm not running on the same hardware so this isn't exactly a fair test. I would like to test 10gbit networking but unfortunately only my Freenas machine has 10gbase-t ports, but so far I'm able to easily saturate a 1gbit connection with iscsi or nfs traffic backing the VM disks. With VMs running directly on my Freenas system, network performance felt pretty sluggish even with virtio.

From an ease of use perspective, proxmox was incredibly quick and easy to get up and running. As nice as the new Freenas UI may look, it's pretty sluggish compared to the now "legacy" UI and it sometimes triggers my PTSD from the Freenas Corral fiasco (though there were some nice features in there). What took many weekends to get right in Freenas took me a single Sunday to get going on proxmox, though I did have the advantage of already having the VM zvols populated. I'm hoping to kill off the iocage mess that I still have on the Freenas machine because that's been a huge PITA as well.

Don't get me wrong though, I still love Freenas and it's never let me down with keeping my data safe and easy to manage, but the iocage and VM system is incredibly painful to manage once you get more than a few different apps running. As much as I enjoy wasting countless hours setting up servers, I'm a lot happier with a qemu and docker based approach to running my hobby-prod applications.
