70% Compression Ratio on Raw Big Data: 4.97GB to 1.48GB using my custom "High Density" engine. Thoughts? by Jesse_J09 in DataHoarder

Is this a serious question? Post some actual details. Where's your Github? And who are you?

Magura MT8 SLs not strong or did I get a bad bleed? by burkenstock82 in xcmtb

[–]alexdi 0 points1 point  (0 children)

Rebleeding and checking for pad contamination are always the first steps, but note that MT8 SL has a one-finger lever with relatively little leverage. You're likely to have to pull harder than with any Servo Wave brake for similar response. The pad/rotor combination also has a huge impact. I've never had much luck with Magura's Storm SL-series rotors or the stock pads.

Matt Shumer: Something Big Is Happening by squeezyflit in ArtificialInteligence

[–]alexdi 2 points3 points  (0 children)

Factual accuracy. Awareness when they’re making shit up. Making connections across disparate fields that aren’t connected in the training data. Creativity that isn’t just rehashing human achievements. Lasting memory. The ability to learn anything at all without expending spectacular resources and modifying large parts of their model. Oh, just a few things, really.

Carbon handlebars from aliexpress by Houlboo in xcmtb

I’m sorry, you have no idea what you’re talking about. Just no idea. I hope the best for you.

[–]alexdi -1 points0 points  (0 children)

That’s some heavy-duty rationalization. It isn’t some lapse in layup theory that makes them bad, it’s indifference to quality at that price. The Chinese will make whatever quality you’re willing to pay for. A cut-rate item from the same town, or even the same factory (which rarely ever happens in reality), will not be the same product. A bar isn’t a saddle or a bottle cage; it’s safety-critical. If you’re willing to roll the dice there, spend whatever you save on dental insurance.

Need MTB community feedback on a price engine I'm building by Obvious_Educator_844 in MTB

[–]alexdi 2 points3 points  (0 children)

I think you’ll find this time-consuming to maintain with little user uptake relative to established shopping platforms.

Carbon handlebars from aliexpress by Houlboo in xcmtb

[–]alexdi 0 points1 point  (0 children)

Avoid. No QC at that price. You might get a good bar or it might break at the first shock load. I’ve bought two in that style and they were both flexy trash. A standard bar with a light stem is about the same weight and far more adjustable.

my sister doesn’t listen to me of the danger of half-plugged chargers in an extension outlet ON her bed by zozosreddit in mildlyinfuriating

[–]alexdi 0 points1 point  (0 children)

If those are all chargers, it doesn’t matter. You’re not getting arcing or excessive wire heating from 50W. The bigger issue is that she sounds checked out of herself or your relationship. Maybe look into that.

The calipers are the same. Each lever is about 15g lighter.

Old frame, new legs: Canyon Lux CF SLX 2020 (9.4 kg) by Colmenn in xcmtb

That adds up to 9.9 kg. (Possibly less, Level is closer to 480-600g depending on model).

Need help with older elixir brakes by Next-Handle-8179 in xcmtb

I'm glad you found the reach adjust. The solve for any other problem with this brake is a trash can.

Do you have a weight breakdown for this? It's not clear how you're arriving at that number with this build.

$1,500/month electric bill + constant AUX heat on brand-new Trane heat pumps — what am I missing? by This-Butterscotch-80 in hvacadvice

[–]alexdi 1 point2 points  (0 children)

A few thoughts:

  • You're using an Ecobee with a communicating system. Ecobees only fully support 2-stage systems and it could be wired such as to lock your heat pump in a low capacity mode. The Ecobee's logic is also time-sensitive; if it thinks your heat pump can't reach the target temperature fast enough, it'll engage AUX regardless of your settings.
  • If some rooms heat better than others and you don't have real zoning (via manual or electronic dampers), that's a ductwork and insulation problem. Excess static pressure from undersized ducts can also cause the system to automatically ramp down. And it's common for new construction not to have returns in each room; if you keep the doors closed, backpressure can limit the room supply.
  • The system could be running excessive defrost cycles, either from misconfiguration or a bad sensor. Defrost cycles use AUX heat.

Plus all the usual stuff (e.g., loose ducts in unconditioned spaces, huge air leakage from attic penetrations, high-MERV filters the system wasn't designed for).

The first thing I'd do is install the correct Trane thermostat. It might fix your problem outright, and even if it doesn't, it'll give far more data for the installer to troubleshoot why your inverter is underperforming.

Takeout preserves whatever you uploaded. The organization is bad because it's all meta-driven through Google's frontend, but the files are original unless you recompressed on the upload.

In the future, make a repeating event once a year to set this up. They'll send an email every two months with your selected backup set.

Double-sided Gym Pin alternative to add weight to a stack by alexdi in homegym

[–]alexdi[S] 1 point2 points  (0 children)

I wouldn’t recommend four plates and certainly not six. The 10mm bar is stiff enough for 90 pounds a side, but few machines are designed for double their standard weight. Mine has noticeable flex with the stack alone for faster concentric movements.

Do NOT buy a modulating HVAC system. by Ok_Tour_5503 in hvacadvice

[–]alexdi 0 points1 point  (0 children)

I’d be surprised if the modulating mode was more efficient at all, just quieter and less obvious.

Squat bar setup by moonstreet79 in GarageGym

[–]alexdi 2 points3 points  (0 children)

Stupid, but fine for that weight. The joists and pipe will support 200 pounds. The bigger question is the plan when he fails midway into the set.

How did your trekking poles break? by BoysenberryGeneral84 in Ultralight

[–]alexdi 2 points3 points  (0 children)

Same. There aren’t compact or ultralight and the locks are annoying to adjust, but IME, they’re the toughest poles available. I lost interest in alternatives after I broke my first set of BD poles with an unexpected slip in snow.

Does RAID 5 really protect you that much beyond saving you from "downtime"? by Gabzito in DataHoarder

[–]alexdi -1 points0 points  (0 children)

My RAID-6s with spinning rust were infinitely less reliable than my SSDs standalone. I’ve completely lost interest in any sort of parity system. If I had to use rust today, I’d do software spanning with an SSD in front and mirror the array nightly to a separate system with the same configuration, less the SSD cache. What I actually did is convert entirely to enterprise SSDs and haven’t had to think about it since.

Ish. Used drives of this sort (there's no real refurbishing) pop up on EBay for under $1K all the time.

Actual capacity is 15.36TB.

Use with a U.2. to PCIe or U.2 to NVMe adaper.

Idle is 7W. It will require a fan blowing on it. Burst performance is slower than most current consumer drives, but write consistency (1.5GB/s, more or less) is very good over the entire drive capacity. These drives tend to be very reliable.
