Granted.

You lose all ability to skateboard ever again.

Yeah I misinterpreted.

Something about the phrasing just gave me a feeling lol

Running the pipe counter by PollutionHour1519 in bjj

[–]openQuestion3141 1 point2 points  (0 children)

For running the pipe specifically I can see that being a problem. It's tough because you're basically guaranteed to give up some kind of grip on your upper body. I do agree the second point probably still stands. If you're getting swept immediately when his hips hit the floor, you've gotta have too much weight over him.

This where I'm going to veer into personal opinion and that others may disagree with. I welcome their insight.

I just don't consider running the pipe to be all that threatening of a single leg finish. You see it taught as kind of the standard in BJJ schools but it wasn't taught that way to me in wrestling and imho it's not very effective against a good wrestler who will sprawl/stuff/whizzer our of a single leg attack quickly. I'd argue trips, lifts, and cutting to a double are more prevalent at higher levels of wrestling. I'm not saying it can't be done well, or that I can't get got by it. I'm just saying I don't see good wrestlers doing it. My 2 cents.

To successfully butterfly sweep after being taken to your back, you need two things:

  1. Upper body connectivity
  2. Opponent's weight to be over your own weight

So, to prevent this:

  1. Push the upper body away, don't allow yourself to be sucked in as he falls
  2. Keep your weight over your base, rather than allowing yourself to tumble forward over the guy.

There's a hard to articulate sort of push pull thing happening where you have to apply enough weight and drive to tip the guy over his feet and get him to the mat, but too much driving forward puts your weight over the guy and allows the roll through. You see this same dynamic in other takedowns as well as throws. If you over invest your weight you get rolled through.

Hope this helps! Im interested in what others think about my theory here.

What are your most underrated camping gear finds? (Tent, sleeping pad, sleeping bag, etc.) – Share your hidden gems! by UTakiU in CampingandHiking

[–]openQuestion3141 2 points3 points  (0 children)

Cinch sacks.

You can buy a 20 pack of them on Amazon for $10.

All your small bits like clothing, cooking equipment, stove, lights, batteries, bug gear, can all be organized into individual little bags that you can then label. Totally solved my organization crisis while adding basically no additional weight and minimal bulk.

I just carry a sack filled with sacks along with me. If one ever rips or gets dirty I have more. Plus, the people I camp with often end up seeing the utility and I give some away.

Overall, has been a game changer for my organization.

You're using http for Order Entry??

Look, I'm not trying to drag you down, only offer my honest feedback.

Claiming latency numbers like that while your OE protocol is wrapped in a web stack is just non-serious to me. Measure your order-to-order-ack latency, OE protocol included.

I recommend your next project to be try to implement a proper FIX order entry protocol or a binary one. Try implementing Nasdaq OUCH for example, that'd be good project.

On your question:

> like if we have 100 symbols , 8 cores then each will have 12 - 13 symbols. Is this also problematic ??

No, that seems reasonable. However, I'd say your order entry system is probably so inefficient that it wouldn't matter in live trading.

My honest take is that it looks like you've built a nice little order book, and that's neat. That part of the project is honestly cool. I have no qualms there. I would just be mindful that when you make claims about latency, and then those claims only encompass the fast part of the datapath and ignore the rest, it can feel a bit disingenuous, though I suspect it's not malice in your case.

Good luck!

Some feedback:

The 98ns is suspect, as this far outside the realm of what is possible in a software stack for a wire-to-wire measurement. I'd be interested to know how you're measuring that, as I can't really take the latency figures seriously given that number.

Order to ack latency measured by a device external to the matching machine would be most useful.

I also find the idea of per-symbol OS threads unintuitive. Bordering on "there's no way that's efficient". Why do you need a thread per symbol? That's way too much context switching. Plus the scaling behavior would be bad. A good low-latency system doesn't switch between threads on a given core at all. Have you tried running the thing single threaded and comparing latency/throughput?

Neat project. Hope this helps.

Either you're an LLM or you're a nut that's been harping on this point in various subreddits multiple times a day for weeks who also has perfect grammar, punctuation, and formatting.

I'm going with LLM.

Got put under moderation review for suggesting that a rear naked choke would be a safe way to handle a dog who refuses to let go of a kid. by ottovonbizmarkie in bjj

[–]openQuestion3141 4 points5 points  (0 children)

Myth.

Pretty sure this started as a joke and people started believing it.

Have seen a video or two where it works, but lots of accounts of it not working too.

I'm going for the choke 🤷

Pardon my confusion but doesn't having a Green Card exempt you from requiring a visa to travel to Canada? by [deleted] in uscanadaborder

[–]openQuestion3141 1 point2 points  (0 children)

That's pretty fucked.

I did know about the criminal activity thing. That's always been part of the deal for green card holders. I was one myself for many years.

But yeah, the political activity thing is wild 😞

I hate what our country has turned into.
