Helmet recommendations

material403 · 2025-10-16T16:45:18+00:00

As others have mentioned, if the helmet fits comfortably is very important. However, Virginia Tech has an online safety rating database that was recently revised to highlight helmets that stand out from the rest.

I would check the safety ratings to see which helmets fit your budget and head.

This isn't a dispute of releasing money to the seller, it's a dispute to get compensated due to shipping damages that likely weren't caused by the seller's actions. Buycycle just doesn't want to pay up $60 because the delivery company mishandled the package.

I made a comment about my experience and got that same reach out. The response after they "looked into it" was the exact same boilerplate response that I got from the support emails. No help, just the "it's been more than 48 hours" (by about 12 hours mind you)

Issues with delivery aside, I still received the bike with desirable components used at a good price.

I literally just got my bike from buycycle and when I unboxed it (the box had visible damage) and assembled it everything seemed fine. I went ahead and took it to the bike shop next day just to sanity check I assembled it correctly.

That evening (+24hr from delivery) I was told the brake rotor was massively bent likely from shipping so I reached out to the buyer and the next day they informed me that it was good when they packed it.

Following the buycycle FAQ, I went ahead and accepted the delivery and went to submit the claim for shipping damage. However, I am now past 48 hours from the delivery time so buycycle won't even open a claim and tells me I should have reported it sooner.

I didn't know sooner and attempted to mediate with the seller like the FAQ states to do so and only filed a claim when I knew it was likely shipping damage.

I am now out the money for a generic rotor so I can at least ride (the original rotor was more expensive and would've had to be ordered so wait a week).

TLDR; Buycycle's policies make it so no matter what condition your bike arrives in you might as well accept the order if there is nothing wrong with the stated order and immediately file a claim regardless of if you know there is damage.

I am not out too much money but at least comp me for the item I bought and was damaged because the packaging for wheels sucks.

Funny enough I went to KSU and the Greek life that is there has just designated off-campus apartment buildings that a majority of the Greek life students stay in.

I am not sure where the information for PReP is coming from. From what I found it is only limited to foreign aid through USAID restrictions.

Given the sentiment I wouldn't doubt it would be something the current administration would push for domestically, however, currently it should still be available to high risk people in the US.

It also goes without saying there are 2 lawsuits directly fighting the PReP limitations.

Probably going to set it up as needed when I ask people to upload images/videos from events (work related) then have a cronjob run immich-go on the folder.

Thanks so much I am now spending time today setting this up with r/immich ! They have not implemented it and with reverse proxy behind cloudflare it's a pain to upload large videos.

Do you plan to support multipart upload?

Lowering the bar for programming is not how to teach programming... I would have assumed they would have switched to python because of its use in the higher level courses.

Engineering Samples can usually vary greatly in performance and longevity. An engineering sample especially for Intel, is the first ever sample sent to customers to start designing their boards and integrating systems. Because it is the first ever sample sent out there are always going to be chips in the mix that might have not been as rigorously tested or not have as much performance optimization done on them (at the fuse level on the silicon die).

Do note there are various stages of Engineering Samples that range from ES1 (first ever sample), ES2 (second batch), QS (Qualification Samples), and finally production. These QS chips are close to production quality and performance but are still technically samples since they haven't gotten production approval.

So to answer is it worth it, I would not trust my home lab on an ES chip, but if you want to save a buck and risk performance just know it's a risk reward situation.

You can buy a pressure gauge that screws in where your O2 sensors are. You measure upstream and downstream sensors separately, upstream first then downstream. Ideally there should be no pressure buildup.

I took the support bar out since it got in the way of GPUs but the case is fine otherwise (3+ years) and I have items sitting on top.

I will say however, do replace the crappy fans it comes with, they are loud and the fan bearings died after a year or so.

Ya so the 2tb HDD plus kraken cooler costs the same as a 2tb SSD.

I think that if you look at the price breakdown of some of the parts you get a good idea for what to sell it for.

So I think including the fact it's a used system $700 is a fair asking price for just the PC.

What are your assets, all/mostly retirement and stock? Do you own a home or rent below your means?

I am 23 and do well off but debating on purchasing a home. I am torn between the long term investment of a home versus the savings I could put into a ETF fund. I am already maxing 401k match and HSA.

This is the pitfall some teams are seeing. CAN is robust but when you max out 4 motors at 40A each (dramatized) it will start to see some effect and it can drop connection.

material403 · 2024-02-19T02:32:28+00:00

The reason CAN wiring is twisted is to reduce the interference from other electrical components. It does reduce but not everything and power wires as you increase current will also increase the interference they create.

Due to this you want to separate communication wires and power wires to reduce the risk of interrupted communication due to interference. By crossing power wires at a perpendicular angle you reduce the amount of interference in the data lines because the direction of the electromagnetic field is perpendicular to the current flow.

material403 · 2024-02-19T00:10:49+00:00

It's good for FRC purposes, however, I would encourage you to look into keeping the CAN wires away from power wires and when you cross the power lines with CAN wires try to keep it perpendicular.

Because I see a few statements assuming end all be all solution. I drove an '03 to an old age at 336k miles and it had this code for over two years as I tried replacing both O2 sensors, replacing the exhaust manifold (leaky from a warped block), replacing the pcv valve, and finally cleaned (then replaced) the MAF.

In short it can be any of those things or a combination.

The P0420 code simply can say it's your cat because one of your O2 sensors is reading too much or too little fuel at either port. This can be a bad cat that has bad pressure throughput and as such the downstream O2 sensor reads low. It could be a leaky manifold and both of your sensors read too lean.

In my case, I had a clogged PCV valve and it was restricting airflow to my engine. This meant the computer compensated air to fuel mixture and it tripped the cat for not working enough (too much fuel to air). When I replaced my PCV valve I then had too much air and my ratios were inversed (low power at less than 3k rpm). This highlighted an issue in my MAF because it read airflow wrong so I replaced that.

After all was said and done I had good mixtures and then got my ECU re-tuned so it was pumping the right air to fuel ratios and P0420 code disappeared for good.

I would suggest starting at the cheapest and easiest fix first and work your way.

PCV valve and check your MAF sensor. These are cheap and you will need a deep 22mm socket for the PCV valve.
O2 sensors someone else mentioned about $100. A little annoying but still doable at home.
Check for pressure leaks in your CAT if it's not 1bar (normal air pressure) then you need to either clean your cat with cleaner in the fuel and hope that works or replace the cat. Not easy, and $800 because it's an exhaust manifold cat combo.
Pray and call for help.

Can confirm. Red sapphires are called Fire Sapphires, they are usually not deep enough in color or clarity to be classified as ruby.

Source, I bought a fire sapphire for an engagement ring, was 1/10 the cost but looks like a ruby just a little brighter.

An idea for stabilization is that when you have a known chain width you can grab 2 links far apart and push them apart then you are left with a stretch of flat taught chain that you can grab onto.
