I have been using Intel‘s D-435i for 6D object Pose estimation and i have to say i was not really happy with the quality of the retrieved depth-frames. The Depth images are very noisy, flat surfaces appear heavily wavy thus making it difficult to apply it for tasks that demand a relatively exact 3D representation of the surrounding Space, which is a problem that has been mentioned in a few issues by several other clients. Just Google ghost noise or wavyy Noise D-435i.

Moreover the AI implementier is actually Not really AI, it‘s just a bunch of common filters for depth-noise reduction such as a Median filter, just look up the filters. And lastly the depth-measurement becomes more unexact the further the point is away, therefore making it necessary to apply a depth-correction, in my case a correction polynom of 2nd Order.

All in all i have to say i‘d not use it again, especially not in industrial contexts. The Kinectv2 delivers a much more stable and reliable depth-image, Even though the realsense programming Interface is mostly nice to work with.
Robinhood goes all-in on crypto trading
Robinhood Q2 earnings are out! They made more money from crypto-trading in the Q2 ($233 million) than it did from options trading and equities trading combined! ($218.2 million). Few takeaways:

1) Total Revenues $565M more than 2x last year $244M ;

2) Net Loss of $502M. All of that loss came from an accounting adjustment related to a change in value of notes and warrants held by the company;

3) Q2 Net Cumulative Funded Accounts up 130% to 22.5 million;

4) Monthly Active Users (MAU) up 109% to 21.3 million vs 10.2 million last year;

5) Assets Under Custody (AUC) up 205% to $102 billion in Q2, vs $33 billion a year ago;

6) The company's ARPU (average revenue per user) was actually down to $112 in the second quarter of 2021, compared with $115 in the second quarter of 2020;

7) Robinhood's Payment for Orderflow (PFOF) - the company's bread and butter and the bulk of its revenues courtesy of its main client Citadel - was hit big in Q2 from a sequential perspective, as PFOF dropped 34% in Q2 compared to Q1;

8) The company also disclosed that more than 60% of its funded accounts engaged in crypto trading during this time;

9) The crypto revenue in Q2 amounted to 41% of Robinhood's overall revenue compared to 17% in Q1. Meanwhile, the meme-based Dogecoin accounted for a full 62% of that crypto revenue—nearly double the share it counted for in the first quarter.

The stock is down -5% in after-hours trading.
I’ll leave Casey Handmer‘s post on solar power from space here, just in case there will be discussion. It makes good arguments why the concept might not be viable.

The same argument could be made for all other data formats.

CSV is like the C of data formats. It's incredibly stable yet simple enough you can make your own variant if you need to.
Your privacy policy is a 9 page PDF, which as an immediate red flag. You also auto share registrants' info for marketing unless we opt out.

As has been repeated over and over, apple only scans photos that are part if icloud photos (ie, uploaded).

"for now"

Which is the part most people have a problem with -- they say that they are only scanning iCloud uploads now, but it's simple extension of the scanner to scan all files.

I don't care if Apple scans my iCloud uploads on iCloud servers, I don't want them scanning photos on my device.
Is this even true? Most of the progress is in "hard sciences" - physics, cellular biology, computational biology, genetics ... where experiments (and presumably reproducibility) is just fine.
How is it possible that there are duplicates?
Until enough people have immunity from vaccination or from having had COVID that we are no longer in the midst of a pandemic.
This doesn't hold much water. As a counter example, we have all of the engineers that designed Facebook, Google, etc. We have people working in ad tech. We have people working in lots of places that you and the people that you talk with directly would be moritified, but there are countless others that need a paycheck and do whatever pointy haired bosses tell them to do.
This is so just because no common software supports them (I don't know why, the libraries are totally free - BSD and Public Domain).

And by the way, many (if not an overwhelming majority) of the non-programmers don't even understand what does "just text files" actually mean, how do text files differ in nature from DOC files and how are CSV files different from XLS files. They can only use CSV because Excel and LibreOffice support it OOTB and consider CSV just a weird XLS cousin needed for import/export purposes.
I imagine they meant even mentioning a statistic like “60% of those hospitalized are vaccinated” at all would get them labelled that way.
It's crazy how much stuff is just no auth and listens on all interfaces by default.
Why is it so important to get an expensive domain? Does the three-letter .com really add that much value? Especially when it's not a B2C product / offering and specific to a focused audience? I'd think a three-letter .com would be something with widespread, international appeal to be worth the expense.
It's difficult to speak off-the-cuff on any topic that might come up in an interview, but I expected better than 'at least it's not boring' about QAnon when attempting to reply on the social impacts of technology.

Social media definitely has negative impacts (e.g. directly tied to mobs in India and Burma) and positive impacts (so much easier to stay connected across the world) - it would've been 'interesting' to hear a more nuanced take from one of the inventors of the modern internet
Oh man. They really want to die on this hill don't they.
Just curious, why aren't you asking this question to the newly created RvSux account spamming this thread?
so, basically your only problem is that the possibility of opt-out may not be adequately communicated? and, i think everyone would agree that changing the law but not telling anyone would be bad and wrong. but, spoiler alert, that didn't happen. and if we found someone who could or did not understand, the default would be to not use their organs.
I really root for Nolan; I very much liked Interstellar and enjoyed Tenet, but I think he's a clear example of someone who excelled so much at a commercial medium that the get-the-most-butts-in-seats factor necessitates the exposition diarrhea. There's just enough ambiguity for the common pseudo-news-site or vlogger to make "the ending of $FILMTITLE REALLY explained" content.

I think Lynch, who's learned to "rule over small films than serve large corporate ones" [1], probably bent over a little bit to get The Return made, but I still left with as many, if not more, questions as I had coming in.

90% of the Patriot Act was permanent law and is law today. A few of the most objectionable parts had "sunset" provisions in them and those (after several rounds of modifications and numerous extensions) are what has, finally, been allowed to expire. Most of the provisions of the Patriot Act are in effect today and will be until a future Congress changes them.
I think this is helpful because it keeps the "issues" tab cleaner. It's a place to discuss initial ideas without finding the maintainers on discord or something, to get feedback on whether the idea is worth implementing a PR for or not, etc.Similarly, it can be used for announcements about the project, polls to the community, etc.
> But yeah if you're a software efficiency bean counter, maybe you won't like FP. Fair point.

> My opinion is the long-term technical & cultural benefits and opportunities pay off.

How, though? These two points contradict each other. Is using FP going to pay off with technical benefits? Or is it just going to reduce your software development efficiency?

I enjoy writing FP code and using niche frameworks like Elm for hobby projects, but I specifically avoid them for production work because I'm familiar with them.

I always hear claims that using Elm and niche languages is going to pay off in vague benefits somewhere down the road, but in practice the payoff never really arrives. I think a lot of developers pushing these niche frameworks tend to mentally dismiss the actual costs and overhead incurred by using something like Elm.

It's tempting to categorize the struggles as "learning" and therefore try to pretend it doesn't count as lost time, but at the end of the day if your team has to spend extra cycles doing extra things just to accomplish basic tasks, it's a drag on productivity.
Funny (to me) story about the first time I watched the first two Godfather films. I was in high school and home pretty ill. My dad rented both films for me. I was so out of it that I didn't know which family was the Corleones until midway through the 2nd movie.
Free speech is not unlimited and it's obviously being used to attack the US.

If you spread falsehoods online with the intent to harm (ex. vaccine misinformation has killed people), then you should have to defend it in court. Let a jury decide.

Gimp has a way to draw circles. You use the circle selection tool and then use the trace selection menu button which draws a line around the selected circle in your choice of brush.
I have a serious problem imagining that Apple will not be willing to redeploy this technology in a novel and nefarious means in exchange for continued market access when billions are on the line.

Mainland China will probably be the first chip to fall. Can't imagine the Ministry of State Security not actively licking their lips, waiting for this functionality to arrive.
Thanks for pointing this out. This is not good and we'll make it better. I'm pretty sure it was a stock policy we threw up just to get going.
iMessage photos do not automatically add photos to your photo library. Yes they’re synced between devices but afaik Apple isn’t deploying this hashing technology on iMessages between devices. Only for iCloud photos in the photo library.
Apple does check it just before you upload it to icloud. How much money do they save it's is checked clientside? How much would it cost for Apple to do it on there own servers, like everybody else does it?
> All of the slippery slope arguments have already been possible for nearly a decade now with the cloud.

That doesn't make it ok. The fact that you and my mom have normalized bad behavior doesn't make it any less offensive to my civil liberties.

> Am I the only one who finds no issue with this?

If you only think about the first order effects. This is great, we catch a bunch of kid sex pedos. The second order effects are much more dire. "slippery slope" sure... but false arrests, lives ruined based on mere investigations revealing nothing, expanding the role of government peering in to our personal lives, resulting suicides, corporations launching these programs - then defending them - then expanding them due to government pressure is *guaranteed*, additional PR and propaganda from corporations and government for further invasion in our personal lives due to the marketed/claimed success of these programs. The FBI has been putting massive pressure on Apple for years, due to the dominance and security measures of iOS.

Say what you want about the death penalty, but many many innocent people have dead in a truly horrific way, with some actually being tortured while being executed. That is a perfect example of second order effects on something most of us without any further information (ending murderous villains is a good thing) would agree on. So many Death Row inmates have been exonerated and vindicated.

It’s not clear it was the FBI, the server was in Bahrain. This could be bigger than just an FBI screwup. Why is US SSI in an server in Bahrain?

Second Order Thinking
No, I'm saying they designed the system so that they don't have the key to decypt the scan result "vouchers" until after the device tells them that the 30 image threshold is crossed.

>Apple is unable to process individual vouchers; instead, all the properties of our system mean that it’s only once an account has accumulated a collection of vouchers associated with illegal, known CSAM images that we are able to learn anything about the user’s account.

Now, why to do it is because, as you said, this is something that will provide that detection capability while preserving user privacy.

Meanwhile, a single false positive from an on server scan is open to malicious use by anyone who can get a subpeona.
It is weird it's not altgr-' and altgr-^ that activate accents.
The L515 is AFAIK based on scanning MEMS rather than structured light on the 435 and together with its integrated “normal” camera should give better results (did for us).
Pretty much any bar in a downtown area of a major metro on the weekends has a bouncer at the door. There’s no planet on which the bartenders could keep up if they had to check everyone’s ID. I suppose you may find the one off who doesn’t but their liquor license won’t last long.
I think this is where a disconnect is occurring.

In this specific case yes. That is what is supposed to happen.

But Apple also sets the standard that this is just the beginning, not the end. They say as much on page 3 in bold, differentiated color ink

https://www.apple.com/child-safety/pdf/Expanded_Protections_...

And there’s nothing to stop them from scanning all images on a device. Or scanning all content for keywords or whatever. iCloud being used as a qualifier is a red herring to what this change is capable of.

Maybe someone shooting guns is now unacceptable, kids have been kicked from schools for posting them on Facebook or having them in their rooms on zoom. What if it’s kids shooting guns? There are so many possibilities of how this could be misused, abused or even just an oopsie, sorry I upended your life to solve a problem that is so very rare.

Add to that their messaging has been muddy at best. And it incited a flame war. A big part of that is iCloud is not a single thing. It’s a service, it can sync snd hold iMessages, it can sync backups, or in my case We have shared iCloud albums that we use to share images with family. Others are free to upload and share. In fact that’s our only use of iCloud other than find my. They say iCloud photos as if that’s just a single thing but it’s easy to extrapolate that to images in iMessages, backups etc.

And the non profit that hosts this database is not publicly accountable. They have public employees on their payroll but really they can put whatever they want in that database. They have no accountability or public disclosure requirements.

So even I, when their main page was like 3 articles was a bit perturbed and put off. I’m not going to ditch my iPhone, mainly because it’s work assigned but I have been keeping a keen eye on what’s happening, how it’s happening and will keep an eye out for their chnages they are promising. I’m also going to guess they won’t nearly be as high profile in the future.
The TSA installs this scanner in your house so it can detect before you even get to the airport. They give a pinky promise they will only run it when you book your ticket and intend on going to the airport where you would be expected to be scanned anyway.

The scanner technology can also be used for detecting dissident journalism, but they say it won't be, it is just for preventing terrorism, but still they say, they really need to install it in your house even though it is only for scanning when you intend on going to the airport.
Though I can tell you that we have 0 marketing so at least anecdotally we're are not using your data
Do you have some examples of sites where the regular site is faster than the AMP one?
It has no authentication by default, and it listens on all interfaces instead of just localhost by default.

I used it for a while at home for a project, and setting up auth was quite a process, very difficult compared to most other databases.
There have been many third parties, and I'm not aware of any that have achieved even middling success (maybe Libertarian?) since I've been alive. How would this party fare any better?

Everything You Need to Know About AWS Encryption
DDR4 has a burst-length of 8, meaning the smallest you can write is a block of 64 bytes (corresponding to a modern cache-line).

It also should be noted that DDR4 has "rows" roughly in the 1024 byte size. A RAS command opens up a "row" (aka 1024 bytes), while a CAS command reads from a column (aka: 64-bytes).

DDR4 cells can only be read once (!!!), and afterwards, the data gets mangled. To prevent the loss of data, all "reads" are first into sense-amplifiers... and these sense-amplifiers can be read infinitely.

This "read into sense-amplifiers" is called a RAS command, and it transfers the entire 1024-byte row into sense amplifiers. A CAS can then read 64-byte chunks from the page at high speeds and randomly.

--------

Before a new RAS command can be issued, there needs to be a few steps.

1. The "current row" of data needs to be written back to DRAM (remember, the data in the DRAM was lost when you read the data in the first place).

2. After writing the data, the sense-amplifiers must be emptied (aka: precharged), so that they're ready to receive the new data.

3. After #1 and #2, it is finally legal to issue a RAS

--------

So in fact, DDR4 RAM is also a block device. Sure, RAS is much faster than a hard-drive seek, but given how much slower RAS (row address strobe) is than a CAS (column address strobe)... a lot of these disk-based discussions (such as B-trees) end up applying to DDR4 in practice.

--------

The only thing that really works like classic RAM is L3 / L2 / L1 caches. Everything else in the modern world is basically a block device.
Slowing the spread isn’t a great goal when the vaccines are only ~40% effective at preventing Delta infection (and that number will get way worse over time)

Natural infection is so much better at preventing subsequent infection/transmission, that we should be advocating for people who are not at risk to go out and aggressively live life. Unfortunately many are not in favor of that because they don’t understand that viruses, and hCoVs specifically, are an unavoidable fact of life (and, indeed, necessary for health at a certain level)

There’s not really a way to make vaccinating kids make sense given that the main benefit of vaccination is personal risk reduction only. Furthermore conditions like myocarditis, which happens in young boys who are vaccinated at incredibly high rates (relative to no vax), are incredibly concerning given that the risk of COVID itself is so utterly insignificant in children.
Right. That's why there's never been an amicus brief or a friends of the court type of document drafted and signed by lawyers.
Once we have a better understanding of our pricing we will definitely do this.
Patent what you can, but that’s about where it ends. Obviously you can’t keep something secret and sell it to the public at the same time. Don’t even think about trying to get investors to sign NDAs because no one is touching that legal minefield.
This is actually anti-consumer and I will explain why.

Most new phones have upgraded charging capabilities, but only with the newest charging brick and cable. The newer Samsung S series of phones do this. If you had the previous model's charger it would only 'cable charge'.
If you had the beefier charger it would 'fast charge'. If you had the latest year Samsung charger and cable you got 'super fast charging'. The latest is a 45w charger they sell for $50 for just the block.

Essentially you will find out that unless you are buying a new phone every year, you will constantly have to buy a new charger and cable to keep up with the new charging speeds.

Oh and good luck finding a non-samsung charging cable that will actually reach' super fast charging' speeds, I've yet to find a 8-10' cable that will actually charge at the claimed speeds.

So really it's not cutting down on waste, either financial or environmental. You will undoubtedly buy yet another charger for more money, packaged in a far-bigger-than-necessary package.

It's all just another way to force the customer into more purchases and hide the total costs.

But hey, people have tons of old cables/boxes lying around, so surely this must be the first pro-consumer move in the history of American companies!
It's crazy how many instances are setup to be accessible from the internet, but they don't bother to secure it.
Apple’s solution more like the TSA agent shows up at your house and inspects your luggage before you even leave for the airport and he pinky promises not to report on anything else he might see while in your home.
It was but it was one we were not in a position to resist at the time. Surrendered to almighty convenience.

But here appears to be beyond the pale such that people are saying "this far, no farther!"
Everything you say is optimizing for the short-term. When it comes to total cost of development, I think FP wins out even if you have to fill ecosystem gaps.

But if you can't afford for ANY time to not be spent directly on the business, don't do FP. Sounds like a pretty brutal way to work.

FP has _throughput_ benefits, but may come with _latency_ hiccups while your team climbs the learning curve (which may include writing libraries.)

If you have frequent deadlines (or treat 2 week sprints as deadlines), then FP won't jive..and you probably have bigger pain points in your company than PL choice lol.
My personal opinion is that in this case it’s going to make a world of difference. Very difficult to know for sure, not like we have a control group, but it’s super catchy and feels premium.
I'm glad to see that there now, thanks!
Problem is not with CSV, problem is with people.

People want to read and interpret arbitrary CSV ... well you cannot read and interpret any format that is arbitrary.

*As a consultant, I’ve written more than one internal system that attempts to reconstruct the metadata of a CSV of unknown provenance using a combination of heuristics and brute force. In short, CSV is a scourge that has followed me throughout my career.*

Ideally this should not happen because you should talk with party that you agree on common format. Someone that would explain what each field means and what should it contain, or at least some documentation for the file, not that it just is a CSV. But of course it always is more complicated than that.

Garbage in - Garbage out, even in other formats you still can have the same problem.

3. TSA installs scanners in all homes, premises to only use them to scan your luggages as you head to the airport and nothing else.
But this doesn't change any of that. It only changes whether the scanning happens on your device as part of the upload process instead of on the server after the upload.
You’re not understanding. Dropbox already does scan your files and I’m comparing Apples actions explicitly to that fact. I’m pointing out that people don’t care about that because you’re literally, voluntarily, giving Dropbox your files. Here, Apple is controlling your phone to tattle on you at an OS level (yes, I know, Apple says you need to turn on iCloud Photos for this to run but the precedent is the problem).
