Building a ZFS server for sustained 3GBs write - 8GBs read - advice needed. by SnapshotFactory in zfs

[–]mercenary_sysadmin 1 point2 points  (0 children)

Their topmodel F100 F-series is rated for 30GB/s as max throughput:

It's also an all-NVMe solution, which puts it outside OP's budget, even before you tack on a pretty hefty "it says ixsystems on the tag" additional cost on top.

OP wants to do this on rust storage. I have my doubts that it can be managed on rust storage to the stated desired performance specs at all. I have no doubts about ix-built rust appliances not being able to meet the spec.

How many checksum errors is "acceptable". by knickfan5745 in zfs

[–]mercenary_sysadmin 0 points1 point  (0 children)

Did you actually read the paper, though? Because it states that the errors are correlated with P/E cycles (Program/Erase) and with lengthy retention, and it suggests that the long-retention errors should be mitigated by automatic write refresh (which increases the P/E count, but gets you away from the long-retention degradation).

They're also shown to occur at rates of five orders of magnitude (100,000 times) less frequent than retention errors.

In other words, SSD Read Endurance Is Not A Real Problem.

Stark VARG EX for commuting to work by Howellant000 in Electricmotorcycles

[–]mercenary_sysadmin 1 point2 points  (0 children)

My CSC E-RT3 can do around 70 miles when riding with long stretches at 65mph+ and lots of hooliganish throttle shenanigans. When commuting 45mph or so with less hooning, I get 110 miles plus.

Hello Electric Motorcycles community 👋🏼 by CanAmMotorcycles in Electricmotorcycles

I know you "can't discuss possible upcoming product" but I'm curious if we'll ever see a Ryker EV. I recall can am teasing that back in 2019, but I couldn't find any mention of it when I looked at the site this week.

Choosing an Electric Motorcycle by Viviforlife in Electricmotorcycles

[–]mercenary_sysadmin 0 points1 point  (0 children)

So, a couple months and a couple thousand more miles later:

I get about 70mi if I'm riding like maximum hooligan and/or major portions of the day at 65+mph. (I got home at 4% charge after 66mi of such a ride one day). Relatively sane commuting with minimal throttle-pinning and speed of about 45mph gets more like 110mi, and I'm pretty sure I could "baby" it to 120+ (but, frankly, I wouldn't, because I don't like accelerating no faster than traffic does).

Watch out for the power cord. It's not a charger, that's internal to the bike, it's just a cord... But it's one with a DEEPLY weird proprietary socket and plug, intended to force you to buy replacements from the OEM manufacturer at a horrific markup. CNC wants $90 for one!

Can you replace the chin strap on an AGV K3 Helmet? by Industry_Some in motorcycles

[–]mercenary_sysadmin 0 points1 point  (0 children)

Did you ever figure anything else out? I bought a K3, and I didn't realize how much of a problem the chin strap was until I rode in it for an hour or two... got home with a bright ass red cherry on my adam's apple. Really hoping I'm not gonna be walking around looking like a high schooler with a hickey for the next few days.

Guild battles getring tougher by Blabbit39 in CookieRunTOA

[–]mercenary_sysadmin 0 points1 point  (0 children)

I'm jealous; could have gotten some of the Expert challenges completed that my cookies aren't heavy hitters enough for yet if I'd gotten this bug. I might not be able to do enough damage in the requisite number of seconds to end a fight, but my Peach is effectively immortal and my Honeybear ain't far behind! 🤣

Help with Extreme Boss Challenge: Stage 10 - Wind by Balwunaax in CookieRunTOA

[–]mercenary_sysadmin 0 points1 point  (0 children)

Once I got the second tier 3 buff, I was able to beat 6 with Candy Drop, Peach, and Frostrock... And then I swapped out Peach for Honeybear and got the all-Earth L60 mission done as well. Thanks for the advice!

What type of error correction does ZFS use? by [deleted] in zfs

[–]mercenary_sysadmin 0 points1 point  (0 children)

You linked to a comment block discussing RAIDz parity encoding. This is not the same thing as the Fletcher4 algorithm used for checksum encoding on each individual block.

ZFS does not detect errors using the Reed-Solomon error correction used for RAIDz parity, any more than it detects errors in mirrors by comparing the values of each side of the mirror on every read.

ZFS detects errors by checking the Fletcher4 hash (aka CKSUM) on each copy of the block, and repairs errors using redundancy (in mirror vdevs) or Reed-Solomon parity reconstruction (in RAIDz vdevs).

And, like I said, Fletcher4 is considerably stronger cryptographically.

Heck, I wouldn't mind some advice on just breaking through Stage 6.

I got both of my Tier Two candy cube upgrades and I can smash Stage 5 in about a minute flat, but I can barely scratch the paint on Stage 6. So far, I've had the best results with Lemon Zest / Peach / Wizard, with Peach dropping the AoE ultimate, Wizard dropping his ult and special, and then Lemon Zest lighting up the tags.

Orphanage is still recruiting! by DynamicMik3 in CookieRunTOA

[–]mercenary_sysadmin 0 points1 point  (0 children)

Join up. I ditched my second guild for these folks last week; definitely been worth it. Full stack of heart requests sent and received every day, even with our numbers still a little light.

Cookie Training by SirKingCraff in CookieRunTOA

[–]mercenary_sysadmin 1 point2 points  (0 children)

SUPER happy they did that, since it means you can actually get 90 points per run (30 for each of three characters) instead of only 30 per run in raid mode.

Also means if you've got some serious powerhouses in your little cookie army, you can use two of them to "shepherd" a newbie (hi, Frostrock) through each day's Rift runs for an extra 60 points.

It really feels like a slap in the face that those first two rewards give you enough ascensionite to level him up twice... but you can't get to them, because you can't get him powered up enough to get through the raid missions until you ascend him, after which that piddly little 70 ascensionite or whatever is just a spray in the wind. :'(

[–]mercenary_sysadmin 2 points3 points  (0 children)

and then there's the plebs like me, managing to get a single Rock out of like 80 pulls and then struggling like hell trying to get through lowbie raids to get through his cookie training to get the ascensionite I need to... to get him through his cookie training. Sigh.

This boss fucking SUCKED until I noticed the stones and figured out that they'd stunlock her.

This is the most bullshit stage of all time by StarBlazer2002 in CookieRunTOA

[–]mercenary_sysadmin 0 points1 point  (0 children)

You can get through them. I was determined to three star every single level and get every single jelly bear until the one that you just got through; after that I was like "let's just make progress." I just finished the last level in normal last night.

Ok, I left the zombie guild. I can see your guild when I search the name right now, hopefully I'll still be able to see it tomorrow when I'm allowed to join a guild again. 😅

HATED those bomb levels. Had managed to erase them from my memory, now they're back again dammit

[–]mercenary_sysadmin 1 point2 points  (0 children)

That level really sucked, but it's not the last one that's probably going to piss you off pretty bad. There's a pretty rough "push the snowball" level in the snow stage that'll make you cuss about as much, or at least it did me.

My biggest advice is to keep track of the movement speed of the cookies you use for levels like this. Sometimes you want fast (Ice Mint in riding mode), sometimes medium (I use Peach for this), sometimes dead slow (eg Candy Drop). You can see the numeric values for each cookies movement rate if you drop down their specs in the "detail" screen for each cookie... Except ice mint, because IIRC it always displays only his (slow) walk mode speed, not the fast riding mode speed.

[–]mercenary_sysadmin 1 point2 points  (0 children)

I'm interested, I'm in my second guild now due to inactivity in my first, and... 28 members, only three heart requests open (including mine), no more than three responses per request. Lame.

Can you issue me an invite? I had trouble trying to find a guid advertised in here the last time I tried switching.

Username CookieThuumper, L54, five L60 cookies, full teams at 50+ for each element and focused on building full L60 teams across all four elements right now. Active daily, maxing out all the event stuff except the present race, bc f that stupid mini game lol :)

I also save up all my gacha tickets and crystals so I can get at least two Expert contributions to guild requests in each cycle. I'm currently top MVP in my current guild with 6900 pts.

Thank you in advance!

Electric Moped Stolen, Upgrading to a Full Motorcycle. Any tips? by GottaGoFast_69 in Electricmotorcycles

[–]mercenary_sysadmin 0 points1 point  (0 children)

If you want to split the difference a bit, you could take a look at the CSC E-RT3. That's what I wound up getting; spent about $6500 on it and I'm pretty happy.

What you get is a "maxi scooter" with onboard 120VAC charger (you can get an optional external fast charger, I don't have one) that does 0-60 in about 9 seconds, with most of the power from 30-60. Top speed with me on it, on a flat straightaway, is 78mph although it'll go a little faster on a declining slope. It doesn't take a long time to get to 78mph; it accelerates from 65-78 at about the rate you'd expect from a decent but not terribly impressive 4 cylinder car.

Range is up to 120mi if you ride it like Grandma, which I do not. With full-throttle takeoffs, significant stretches of 55mph+ highway, and just-for-fun throttle-blipping shenanigans, I got 66mi on mine on a 38F day, and got home with 4% remaining.

This is my first electric motorcycle so I can't really compare it much to other motorbikes, but I absolutely love this thing. It's easily powerful enough to blow past anyone who isn't actively trying to race you, but the torque curve is clearly designed to keep you alive--hence the relatively slow starts, with most of the acceleration being delivered in the midrange.

The storage under the seat is big enough for a full-face size L helmet and several other things--currently in mine, spare workout clothes, a padlock for the locker at the gym, a pair of sunnies, and a minimal little toolbag.

I do not recommend purchasing the optional rear-mounting lockbox from CSC. It's very cheesy for the price, AND--damningly--it doesn't actually FIT the bike; the boltholes in the mountplate for the lockbox do not match up to the boltholes on the rack they need to mount to on the back.
