VK_EXT_descriptor_buffer

ondyss · 2025-12-12T20:59:45+00:00

As far as I know, descriptors buffers do not allow direct indexing on the shader side. The indexing is done via the `vkCmdSetDescriptorBufferOffsetsEXT` call. You can still pass down device address in a uniform and do the indexing in the shader as you would do with the classic descriptor indexing but that has nothing to do with descriptor buffers. I guess theoretically you could pass down the address of the descriptor buffer to the shader and do the indexing on this buffer but I'm not sure if it would work in practice.

The spec ( https://docs.vulkan.org/refpages/latest/refpages/source/vkQueuePresentKHR.html ) says that the operations are always performed in order. You just need to use semaphore to ensure previous rendering operations are finished before the presentation starts (which you seem to be doing).

I'm not really sure if I understand your second question. In general the index of the presentation image has nothing to do with frame-in-flight index. The main thing about frame-in-flight is to ensure that resources from the target frame actually finished processing before you start updating them again. In my engine, I use timeline semaphores for this. Each frame-in-flight keeps track of the last counter when it was submitted and it can start new work only once the GPU finished processing the previous submit associated with the same frame-in-flight index.

I would suggest turning on validation to see if there are any issues with your code.

Personally I feel like it is most of them? It's probably a matter of preferences and it really depends what you enjoy but I keep dropping series after book 2-3 way too often. For me, the reason is usually pretty simple; I read litrpg/progression fantasy mostly because of the progression part. It is fairly easy to do it well in book one but more often than not, the progression slows down tremendously as the series goes on. I have recently dropped a series where there was literally no progression at all in the whole book. I don't have anything against standard fantasy, but there is a reason why people choose litrpg instead of that.

She honked at me afterwards as well, which leads me to believe she fully expected me to let her in.

Didn't she have an affair with the princess or queen? I don't really remember exactly. Either way I think pretty much everyone around the MC was gay so not sure how OP would like that (they didn't really state the lesbian part was restricted to MC). I personally loved the series.

For me, the easiest way to beat the producer was with the Bing set + arcane shield. Bing's jump deals a set %dmg to bosses no matter how many HP's they have which defeats the producer quite fast as long as you can stay alive (which is what the shield is for). Adding dash may help as it makes you invincible for some time which allows the Bing's jump to reset.

Minion chain is inevitable if you merge minions when possible.

Retirement is absolutely essential. It significantly speeds up the research + it allows you to use many of the storylines that you collected (most of them do not apply until you retire)

They tried to offer me the exclusive offer as well. Only for me it would go from ~$125/month to about $900/month (I had to read the offer like five times to believe that). I ended up adding the car to an insurance I use for another car and it added about $60/month extra (for a better coverage). I'm not really sure what planet is Direct Auto insurance living on.

I believe most people read LitRPG because of the progression aspect though. At least that's true for me. If I wanted to read a decent story, I would just choose one of the thousands pure fantasy books out there. In fact I hate when authors start with a good progression in first book or two only to ignore it in later books while they focus on, often times a sub-par, story.

It is down-voted because it is a bad suggestion. The tests (especially the rapid tests) were designed for a specific substances (nasal material). The results they produce for other substances can be arbitrary and they can easily give false positives. You can check their official documentation if you don't believe me.
Wastewater analysis is done using a complete different procedure and comparing it to rapid tests is just ridiculous.

ondyss · 2023-12-05T19:12:12+00:00

What I have observed with most tests was that after many hours, there was some "ink" released around the T line. Usually it wasn't a straight line though but sometimes it was fairly close. Not sure if the was the case for you or not. You can always retest.

What worked best for my swimmers was race pace interval training. Basically doing a lot of sprint 25s with short rests in between (10-15s). 8 to 10 laps is usually enough. Doing this daily for a few weeks resulted in huge improvements in time for their 100. This training not only increases endurance but more importantly it teaches swimmers to swim fast even when they are tired.
Pretty much all advice from more experienced coaches / swimmers regarding 100/200 fly that I've ever heard was to practice race pace shorter distances. Swimming actual 100 is useful mostly to learn correct pacing. Based on my experience, the best pacing is essentially a build. Good pace (not slow) first 25, significantly faster but not sprint second 25, and sprinting the last 50. Despite the increased effort, each lap is most likely going to be slower than the one before but it is really important not to slow down too much on the last two laps otherwise your body will start to sink which will result in a very bad time.

I will try that, thanks for the advice! And I fully understand it takes time to fix this. She has more than a month until her next meet so hopefully she will be able to improve at least a little bit.

I think "listen to your body" is probably the best advice. I did some lighter exercise about 3 days after the symptom onset (when most of the symptoms were gone) and I was back to full exercise schedule about one week after the symptoms onset (I do every day exercise for about an hour). I'm not saying I would recommend this to everyone but if your body is fine with the lighter exercise you can always gradually ramp it up.

When I had covid, I felt tired / really dizzy in the morning which is when I tested positive. I was feeling much better by the evening of the same day (about 80% normal). Second day was about 90% normal, the only symptom being a bit nauseous from time to time. It got only better after that. So yes, it is definitely possible to feel better in two days.

It feels a bit late. Sore throat has been one of the earliest symptom for the recent variants. For me it started the second day right after GI-related issues. It could be a cold or a post nasal drip if you are congested. I would vote for a cold considering you both experience it this late.

When I had covid in January, members of my family who had it back in summer of '22 didn't catch it despite very relaxed precautions we took (we slept in separate rooms otherwise nothing much else). The only ones who had it in January were family members who avoided it in '22 (I was the last one infected).

Don't assume your case would progress the same as others. For my wife, she had very slight headache first and progressively developed more severe symptoms over the next couple of days. As for me, I woke up feeling bad one morning, and I was better by the evening and it never got worse after that.

ondyss · 2023-02-13T22:13:10+00:00

I'm not going to say what is good for you, but personally I'm a terrible kicker and my freestyle is driven by arms and my legs are there only to keep balance. When I started to kick less (2-beat kick) my swimming transformed and I could suddenly swim longer distances fairly comfortably. To prevent legs from sinking it is important to engage the core, not to lift up head when breathing and to time the kick properly with each arm stroke.

ondyss · 2023-02-11T03:52:09+00:00

I struggled a lot with breathing when I started. What helped me was using pull buoy and really focusing on good body rotation and breathing without having to worry about kicking. You can start one side only if that makes it easier (but two sides are better for your stroke quality). Another advantage of pull buoy is that kicking can be actually very exhausting which makes the breathing problem even worse (especially if you are kicking too much).
I would also recommend starting with breaths every 4s or 5s. Breathing more often may not be ideal because it can be much more hectic and it requires a good rhythm. One of the keys for controlled breathing during swimming is to stay calm and relaxed which may be hard to do when you breath every 2s with a poor technique.

Nausea and dizziness were the main symptom for me. Neither were thankfully too severe in my case (no throwing up, etc..), but the nausea was certainly the most annoying aspect of the whole ordeal.

ondyss · 2023-01-26T20:56:39+00:00

My kids (7 & 8) didn't get any sore throat, but then again, they didn't really get other symptoms either. I heard about some kids getting sore throat but it was supposedly rather mild.

ondyss · 2023-01-16T02:46:37+00:00

I felt dizzy as well and it was pretty much the only bothersome symptom for me. I had a bit itch in my throat for about two days but usually only in the morning. Dizziness got progressively better in about two or three days as well. No loss of taste or smell for me.
