Delete and remake your venv, only this time don't pip install requests.

Seems to be a bug with VSCode, just swtich from global interpreter back to your venv after you've installed requests

#

really bizarre

now i am getting on every new terminal a

Should I buy a better laptop GPU as a way to futureproof for AI workloads?

My opinion on the matter is that any attempt to future-proof graphics on a laptop will just reduce battery life and add cost+weight.

Would it be useful to generate Ansible playbooks/roles/tasks programmatically, if I were to be doing a set of similar tasks a bunch of times?

desert iron
#

You can just save some playbooks as presets to use for other scenarios. And the same tasks for more systems is very easy by just adding the machines to the hosts and then let Ansible do the magic to all of them.
Tbh: I love Ansible.

development question, i am developing my first multiplayer game in unity, and i am getting to the point where i am attempting to sync movement, most sources recommend trusting the client, but conventional wisdom is to give the client a little trust as possible, are they any issues here or is it a nessecity to trust the client to sync the movement?

#

i am using the built in netcode package

hearty forum
#

if you don't trust the client at all, you're gonna have a hard time keeping up with server resources

#

so you need to find a balance

thank you @hearty forum , i think since it seems to be the most recommended solution from my researching, i will go with it for now i can always alter later if needs be

So my game has made some good progress today, both the openGL and Vulkan renderers do something. Tomorrow I'm going to try to get the OpenGL one in parity with the Vulkan one.

Yes these are both done by the same instance of the game, the way the rendering abstraction works trivially allows for such tricks!

how much do you abstract it.

I just re-wrote a whole bunch of my code because I'm abstracting it another level

i dont know much about coding ai but is it possible to code an ai that can answer survey questions that you input to it ?
would be to compare how humans and ai respond to particular survey questions

silk eagle
#

well youd first have to train the AI on survey data from humans

#

an AI cant actually answer survey questions, it would have to model its answers on data that already exists

hollow basalt
#

In some sense, so is humans

#

You need to be trained in societal norms by your parents and environment to think

silk eagle

I guess youd want to train an AI like youd train a baby from birth and then see how it answers the questions

#

put some neuralink in a baby at birth and then upload everything it sees hears smells tastes and feels

No free will to think for its self. Chatgpt isn’t actual AI

Also no ability to critically think if it has not already had experience with the topic

Simple stuff like the people who created it are politically left leaning. And if you ask it political questions it will try to sway you in the direction of the left lol

I’ve done testing with it myself

It’d not as intricate as people belief it to be

And while yes peoples responses do influence and let it learn it is still controlled in the way it thinks and responds

It can’t think for its self it can’t critically think it pulls data from what it’s obtained within the guidelines set by the developers

#

That’s legit all I was saying lol

midnight wind

#

🤦🏼‍♂️ then how does it work

midnight wind
#

thinking critically can be probobly achived with enough training data. Think of a human brain, over the years it is getting trained, and part of that is how to think critically

raven pulsar
#

Cause if it learned and reacted accordingly outside of the training guidelines. It would become unstable and unpredictable. It’s answers either wouldn’t be right or would be extreme.

data, not guidelines

raven pulsar

midnight wind
#

there is no such thing as true ai

cyan niche
raven pulsar
#

Funny how when you say something objective someone has an opinion about you always hear about it

cyan niche
# midnight wind there is no such thing as true ai

I mean, even dumber AI is still "true" AI. We can't move the goalpost of what AI is because it offends people's sensibilities of what intelligence is. In software systems artificial intelligence is regarded as the simulated or mimicing of human intelligence by computers and machines. We saw this formally put on paper with Turing's first paper when he invented computers in the first place. Even weak attempts at intelligence are considered to be AI, even if they're poor. For example, a Chess AI which looks ahead so many moves and attempts to select the best one based on a simple cost/benefit analysis.

Formally and in the field, AI is represented by any number of different fields, of which neural networks is only one branch:

Core-areas-related-to-AI-AI-can-be-considered-as-a-wide-collection-of-different.png
midnight wind
#

but there's no non-human influenced AI, because that makes no sense

cyan niche
#

True.

#

But there's the extremely real ability to produce a super intelligence, that exceeds all human capabilities and intellect.

#

It would require combining both KRR and neural networks. But essentially it would give it the ability to improve itself, find flaws in its reasoning, and fix them as it sees fit.

raven pulsar
#

Humans don’t have the processing and learning capabilities that proprietary software can have

#

Simple

#

People forget, and make mistakes fairly often and most don’t learn from them

#

You can upgrade a super computer but not a brain ;.;

cyan niche
#

Consider the problem of a peanut butter and jelly sandwich. You can define this programmatically, but essentially what you want an AI to be able to do is when faced with a dilemma of not having any bread, it'll attempt to find a substitute, so say a bagel. But you'll find this is difficult problem because it needs to reason that bagels are normally cut in half to produce two pieces instead of one, and not to grab two bagels as though they were each one slice of bread.

#

This requires prior knowledge that bagels are bread and are normally cut in half.

# cyan niche ChatGPT is capable of passing this test, by the way:

The issue with that example is you told it about having bagels. If you just say you have no sliced bread, or give it a selection of bread-like products, some more or less suited to being made into a sandwich, then that is a better test of 'intelligence'.
I expect GPT would still pass, but to me seems a more rigorous test

# ruby thistle The issue with that example is you told it about having bagels. If you just say ...

no, it just doesent work intelligently. what is ironic about chatgpt and it being ai, is that it fails as soon as its expected to to do logical thinking while not having that certain example in its database (where it has learned from). As a matter of fact you can test it by asking "if 5 cars need 10 hours to london, how much would 10 need". In this case it will see similarities with those "10 machines make 10 products in 10 minutes how much do 5 machines make in 5 minutes" maths excercises so it will look no further (and will skip the logical deduction to even check if it were the correct solving process (which is isnt)). So to finalise, it is AI but that it doesent have any real "intellingence" (the one we humans do) apart from the logical components in its structure (components in transformers etc.).

#

Its mostly just a compilation of what we as humans did and gave it to learn from, there is no further learning from that point on unless we make more data for it to "extract knowledge" from.

#

And the bagels thing, well you can find a million of people saying to substitute bread with bagels (and vice versa) for many different reasons on the internet (which is also its database, it learned on)

Is it recommended/not recommended to do searching from within an SQL query? Specifically for basic word matching? Say I am displaying a table with a full name, address, and date. Within the query there's not really any problem with adding some checks to the WHERE caluse to check that against a search term. Is that preferred?

# twilit beacon no, it just doesent work intelligently. what is ironic about chatgpt and it bein...

This isn't how ChatGPT is trained. It doesn't search a database for examples, or use existing examples as its basis

It's essentially a text prediction AI. It was trained by using how well it can predict the next word in whatever piece of training data it was currently processing. But this isn't all it is, because it's a neural network. More accurately we created a brain by feeding it natural language so it understands language extremely similar to how we do.

#

Like imagine if you could take a brain and say, "Finish this sentence: 'The dog jumped... '" and graded it based on how it completed it billions or even trillions of times. And each time it did it correctly, it reinforced the neural connections that did it.

#

It isn't all that different from how humans learn language.

cyan niche
#

Like, are you searching the database when the user enters someone's last name?

# 
SELECT *
FROM [users]
WHERE [name] = 'Bob';

This is how SQL is supposed to be used; you're supposed to query it.

peak acorn
#

I just mean opposed to doing any sort of post-query processing instead of in the query

#

so like idk
select u.*
from users
join posts p on...
join comments c on ...
where search in u.name
and search in p.body
and search in c.body

that kind of thing

cyan niche
#

So, in terms of software speed, querying the database is generally always faster than doing post-processing.

#

In terms of reasons why queries ran on the DB are better, there's a number of reasons:

  • Moving the entire dataset over the network is ill-advised
  • Databases have what are called query planners and query optimizers, and use facts about the database to intelligently optimize your query
  • Databases have many tools to improve the speed of queries
#

And normally, when there is some sort of inefficiency that's difficult to correct in the database, you can tell the query planner to do it a specific way.

peak acorn
#

ok, so it generally IS preferred to do any simple-ish searching within the query wherever possible then

cyan niche
#

Yes, depending on the data size and how frequently you're querying.

#

You may want to cache data items that are nonvolatile (such as configuration settings or enum-type look up values).

peak acorn

#

The entire NN was trained off of text databases on the internet, meaning books articles etc. and its no suprise someone would have written the bread substitution at least once. The ai doesent have any concept of what a certain thing is, so it doesent logically deduct why the substitution is possible rather it bases its replies on the dataset it learned on

#

so if it only consisted of sentences where it gets to the conclusion 1+1=3, it will keep saying 1+1=3 regardless of the validity of the statement. It just doesent have a grasp of why something is, as it really just works as many say: "monkey see, monkey do".

#

But of course longer estimates with room for problems and <100% allocation were routinely rejected

#

I can deliver projects on a deadline every time, as long as I control how much time is spent on them, there is a generous error margin built into the estimate, and you don't care if I ship broken garbage if something goes wrong and more work is needed.

Eh?

#

WSL1 has awful IO performance, WSL2 is actually faster for it.

midnight wind
#

Consider using WSL 1 if:

Your project files must be stored in the Windows file system. WSL 1 offers faster access to files mounted from Windows.
If you will be using your WSL Linux distribution to access project files on the Windows file system, and these files cannot be stored on the Linux file system, you will achieve faster performance across the OS files systems by using WSL 1.

inner wraith
#

Yeah I'm not getting anything close to the performance I can get in a VM/WSL2 in WSL1

#

They can say it's "faster" but one of the big reasons WSL1's model was ditched was how slow it was

#

There is stuff WSL1 makes possible that you can't do in WSL2 because of its integrations with the Windows kernel sure (like directly interact with hardware), but IO performance is abysmal

It's likely Yamaha didn't try to recreate the image format and it's probably a collection of files with specific image formats.

Open it in a hex editor and see if you can't spot image header information.

Hey! Kinda odd question that I've had for a while and got resurfaced with the news of Google selling off their domains division to squarespace.
Assuming after that, .dev domains are still a thing and something we can get, I know they're a secure namespace and require an SSL cert and HTTPS. Does this only apply to HTTP protocols (aka basically just websites/apis)? Is it something enforced browser-side?
I wanted to aim it at a VPS I have that also hosts game servers, would I be able to connect to said game servers with it as if it were any regular .com domain?

Anyone familiar with python re know how I can find the first occurrence of a pattern in a string, modify that pattern by adding/removing (etc) characters, then put the new modified pattern in a substring?

For example, if I have "2x" and I want "2*x", I can find and replace the pattern with re.sub()

import re
string = "2x"
substring = ""

if " " in string:
  string = string.replace(" ", "")
  pass

while string != "":
  modified = re.sub("^\dx", "idk what to do here", string)
  substring += modified
  # remove pattern from string here

# clear spaces in string

tupleMatch = matchObj.span()

# peak acorn Any UI suggestions for styling these buttons on the table?

Looks more like a list than a table to me. 🤔

Could you maybe use an icon, like pencil, instead of a long name? Similar to the trash can. Then you could put it right after text and turn the text into an input field on click.

Normally I’d question if you should even be able to rename in the list like that, for example does clicking a list item show more info on the right there? Looks like there is another card, is so maybe that’s where they should be able to rename.

#

Also you could possibly remove the trash icon and have just the edit + a select icon. Then when they select items trash appears, that’d also allow them to bulk delete.

#

Kind of hard to suggest without knowing what the user interactions are, for example how often do you expect them todo these actions will help determine how many clicks are okay / how visible it needs to be.

Sorry, yeah, a list is a better name

Reliability is a design decision.

wind horizon
# inner wraith Sounds like a you problem, I have worked with infrastructure with years since it...

Not a me problem since I’m not maintaining it. That’s exactly the problem, a lot of corp IT depts aren’t staffed well for maintaining systems and they have more outages than cloud providers or another common issue I see is infrequent updates to internal hosted solutions, like GitHub, because the just don’t update it often.

On average I’d usually take a cloud hosted solution over an internal one. If it’s a small IT/ops team I’d be more open to it, since they tend to be better at being flexible and move fast.

inner wraith
#

Poorly staffed and more importantly often poorly planned

#

I've seen some really incompetent IT teams

wind horizon
#

Yeah I think staffing is the biggest issue, mix of understaffed and not good staff / budget constraints for hiring good talent.

It seems way too common for there to be people in upper positions in IT depts with no clue what’s going on. Lol

inner wraith
#

Yeah I think for some when they get into senior management they end up one way or another not communicating problems to the executives and they don't really know all their shit's degrading until it's far too late to fix with their current IT/ops manpower

#

If you keep on top of it you don't need a massive ops team to maintain infrastructure

wind horizon
#

Yup but so often IT dpt is viewed as a cost, so companies try to cut IT until it’s barely staying alive.

inner wraith
#

Then you lose efficiencies, then it kinda collapses from there

#

That's how you end up like my former clients at my last job with Server 2008 machines with no patches ever in 2022 with no plans to replace

#

Hacked, of course

#

But that doesn't mean SaaS is automatically a better option though for those teams it likely is

wind horizon
#

Yup, glad I’m no longer in ops. Haha

I mean the work was fun and I’m sure there are those good companies that treat you well. But it just seemed too common to get treated poorly and underfunded.

I sympathize with them still, but I just need stuff like git to be working and don’t want to deal with IT outages. Lol

Granted at the small business and then here at the big business it has been solid. It seems medium size business I worked at struggled the most.

inner wraith
#

It depends on the company. My clients ranged from thousands of systems to a very large multinational telecom company and they all sucked

#

They bought our software because they sucked and got hacked for it

#

Imagine: having to explain to the head of IT sec of a multinational why HTTPS is still secure if it's not on port 443

wind horizon
#

With a SaaS solution I guess the one nice thing is if they have an SLA you can get some money back from outages. But doesn’t recover your biggest loss, which is staff not being able to work while your paying them. Lol

inner wraith
#

At least with IaaS you can decide how much redundancy you'd like to pay for

wind horizon
#

I had to explain to an IT person the other day https was on port 443. I’m like umm shouldn’t you know this already, I could see asking to confirm it’s not a custom port but they sounded like they had no idea at all what port https would be on.

It's really worth renting just host machine with good connection for costs sometimes. We had hyper-v host with at least two other lesser machines in same city close by. But that was the very demonstration of being locked to same vswitch which meant same two datacenters in one location which was ultimately from exactly one and same provider

#

The more 'yours' it is naturally saying the same thing as reverse compliment: the less 'theirs' it is. Which on paper is the sooner what theyre responsible for in sla ends as you move from ground up to whichever service you required sitting on top of everything

#

In practice, you'd be least responsible if you don't own everything except for whatever you actually need from host. If the SLA defines the service as managed innodb cluster itself, they are responsible for providing it to minimal guaranteed uptime, being operational usually. They are responsible for literally everything else below it down to bare metal.

#

So if you want to have a physical hosted server with mysql, you want optimally managed mysql db. If you want a second service like prod rabbitmq + java application prod runtime, you should max get some virtual machine with enough physical resultant capes. 'Cores', ram, storage, storage speed, cpu speed, etc

#

Worst case scenario for both is renting metal box and managing everything on it. So windows server on it set up as hyper v host. Then two guests or something one with mysql and the other with runtime crap.

#

If you have a host that's yours to bare metal, then you should specify exactly what 'problems arising from something internal' means. On bare metal host, I've seen this. Sometimes it even means coping or trying different host (maybe now is best time to consider different approach given migration regardless)

#

So for instance they still are responsible for building you PC, hooking it up and making sure that it's running. Or at least can be booted at all times. That's their service. They also hooked up storage which both volumes were SSD arrays

#

Those begin failing. Or you have bad RAM stick in machine. First you gotta prove to them it's hardware issue. Ours actually fought us on that for a while. Technically, they have to examine if hardware is broken and fix it but you're in charge of OS and everything running on it. Even if they offer and agree to run tests on your host, they have to ask for permission officially for certain time

#

They can run perf metrics logging, stress test, poke around for system logs starting from host OS (ideally but ours didn't; I had to). Upon agreeing to give access to employees, you usually agree to their waving responsibilities of even service itself breaking/losing data/blah

#

So like 3 techs in your environment who asked for root access to windows hyper-v guests with oracle linux on them run test for a week inside services' guest envs themselves (they had a linux version specifically for our scenario)

#

You don't know if they're legit enough to at least not do anything bad or skilled enough to cause accidental damage. They're not responsible specifically because you asked them to dig around in "your own" portion which you're responsible for tbh by default

wind horizon
#

Nah I’m just talking pushing a simple container image and having it run, nothing special or server permissions. Even internal only where there is no needed SLA, just over locked down imo.

silver furnace
#

Well I mean the SLA is what you can look for with certain common traits:

#

Service = what you need exactly hosted. As little as possible of the underlying infra to run
Agreement = guaranteed that service will be rendered and made available and functional to guaranteed minimal extent. Usually minimum up-time as percentage or fraction over 95%.

wind horizon
#

It’s not related to SLA in this case, it’s security controls locking it down make it very difficult todo anything in cloud providers at my job.

silver furnace
#

They define mitigating cicrumstances out of their control like power loss, natural disaster, etc, etc. Those are only ones that can cause downtime max complimentary portion of time without xx days warning in advance

#

So also minimal time warnined in advance if it will be unavailable. They still can't do maintenance shutdown if uptime min isnt met

silk eagle
#

solid 95% uptime over a period of 100 years

wind horizon
#

I think most the people here are familiar with an SLA. 😅

silver furnace
#

So already, you don't have to worry about whole host as it sits on bare metal. It can even be same host itself just that they rent you your 'windows server or linux vm'. IRL the cloud is datacenter racks with your pc in it being real metallic one. Now they have to run around and make sure it's up. When you click 'make backup image' or 'restore', they have to literally clone hdd or copy min file system somewhere now :P

#

But most importantly an instance on cloud host or vm you've removed yourself from at least bottom metal layer. Either way, metal runs it at some point but you never have to worry about it. All you know is machine should be on.

#

On Hyper-V metal host, machine is on but like one of the ssd arrays' volumes just gwent because of harware error

#

You're responsible for all guest hyper-v vhd images but also the backing up/restoring etc of what's on those ssds at host level that's sitting directly on top of metal. It's just an impractical place to divy up responsibility between you and whomever hosts.

#

Practically, even if they offer some sort of administration interface that usually has at least power button and open live support ticket for machine, any possible backups or storage space for that simply doesn't exist in anywhere as near of a practical way as your snapshot on cloud host or better yet container deploy configuration. Either way it's a hard drive and something is going to clone the volume on it. Nobody wins

#

Or like you run out of connections on that bare metal arch's gen they built you 4 years ago. You're forced to rent another machine in same physical location from them just stripped down NAS basically. Then you hook up second RAID array of anything but you know it's just as physical over network. It bugs out when you restart 'your' rented machine and they have to fix connection somewhere in provider's v-switch

#

In other words, you can't reboot your machine and get half storage back without opening ticket. We pretty much just got ready and pre-opened lol

#

Even without migrating away from that host, any 'upgrades' or changing tier of service, etc (we were planning to) is inevitably giving you different physical machine. They simply can't really do anything else themselves from the looks of it lol kekw

#

But it's entirely on you to move whatever it is over to new box. That's guaranteed same transfer over network somehow. Theirs is by far the only fast enough location to compare to your snapshots of cloud hosted machine

#

Ideally, we'd get managed instances from some one provider of every service we had running inside guests. So you have managed mysql hosting. You originally used an innodb cluster with 3 nodes. You look for wherever you can rent managed innodb cluster and not pay for 3 separate instances. In fact, you can't.

#

But when you used innodb cluster as one base with just load balancer and 2 read only nodes, you don't even need a cluster anymore. Just get same managed innodb compatible base. You didn't need 3 machines to be 'yours' and manage a cluster. You needed db

#

When I was onboarded for that specific job where I had those personal experiences, I was staring at one host with all 'services' being inside their own guest vms all under the one and only windows server host. There was system drive and the terabytes of storage were on two volumes. Half the vms were stored on directly connected ssd array. The other half was on a separate machine only because it ran out and additional device could only be over network.

#

I was like lol why do we even need this. What's the point of separate machines. All 3 instances in cluster and even load balancer vm everything connected through were on the same connection to same SSD array PogChomp

So we were tripling writes just for the fck of it. The guy who's been there since beginning was only one who really knew what was good. Sometimes the cluster crashed and took down its vms along with that half of guest vms stored same host volume. If it needed to be rebuilt in core hours, we ran standalone one node for weeks or months eventually until we could plan downtime for maintenance (where I spent at least 40 mins cloning two nodes from the one that ran by itself during that time)

#

What's funny is we never gave two craps about which node to resume. The read only or just 2 for some reason was the most likely to binlog with last id or something. I always ran the first because it was just the default one set as r/w. Nobody cared about what was lost because it was always something with crazy writes going on. This was always a batch task which in our application didnt have any use until it fully ran

#

So we didn't even care about the fault tolerance. It always just crashed together and hopefully at least one of the three copies still has the previous data before whichever transactions led to crash. One time I didn't notice but just first node had config the original brainfather of this infra made. It like disappeared. I guess inevitably a result of guest vm crash. Up until I left luckily we didn't lose copy of the running sql data

There were backups cron job which were just mysqldump of all individual db but it was wrong options. Even restoring a single schema w data from them to prod was a pain. I would shoot myself if the day came when I had to remake from scratch using those dumps. Btw all those dumps were sent to the third and last server we had in same location from exact same host. This one was centos on bare metal too I think but it copied over sql dumps via rsync so scp I'm pretty sure.

#

But here I guess the thing to notice was we tried to use it as that service. We dumped ideally from just one mysql innodb compat server something to store and later be able to image over entire same innodb mysql. Sadly, we were not backing up innodb but anything inside it. Hopefully innodb but sometimes a few tables weren't kekw

#

Which should backup and restore 'fine' as far as that goes for me having to do so. Again, thank god it never came to that but I think fine here means possible at least. Sometimes certain employees didn't even care about innodb compat and made tables in their 'sandbox' bases used for testing pre-deployment code something that would only slide in myisam or some sht

#

So sandbox was on prod. Somebody writes a thing which doesn't even replicate in innodb. It spams errors and stops repl. This leads to RAM usage until it's all gone. VMs run out of swap space and die somehow. Other vms on same host storage die too. Half of prod services now frozen 'xfs please remount partition'. Reboot.

#

But tbh everybody needed just mysql server. Why should every dev care about constraints innodb cluster has. He made myisam table or something lmfao. Tbh why we were testing pre-deployment code on sandboxes in production base is a better question but even more stories.

#

Tl;dr the last time we forgot about rebuilding cluster for like 2+ mo and no issues. Only I remembered. Lead programmer forgot briefly but I reminded him. He secretly wanted to get rid of it and didn't say a word kekw

#

When we tried convincing team lead again to just get rid of it because it will increase performance and get rid of issue no matter what, he still kicked and screamed unless we agreed to 2 node cluster PogChomp

#

2 node cluster is dumb regardless. We weren't using it for any normal purposes. He reminded me that it's at least one redundancy of living base. Basically he remembered that we have only hopefully full backup dumps after that pogPogChomp 💥

#

Either way, it became every two days at some point which wasn't enough on the other hand. It would literally set back up to 48 hrs of data entry, analytics, etc. I quickly switched back to his side and left one ro node for backup. But I also stressed how I wanted to schedule a brief downtime for copying the redundant my instance to other physical ssd array. I said that if the ssd array itself is dying (which we thought might be happening and they had issues like that before), both would be affected by total data loss

#

Also it would have halved writes because it's still 2x. At first we were literally in the end of talks about getting separate fourth machine w them (as always) because we wanted more memory for runtime and dbs. Were gonna build same thing and move some of guests to it.

#

I said it would be first scenario where mysql cluster would even make sense kekw

Then he like sold company to one of our biggest clients which had most states subcontracts, they began rewriting it on azure (good for them as long as it's going to be properly this time). Last I saw they outsourced data transformation specialists to go through and restructure literally all data for presumably rewrite which doesn't exist yet 🙃

# wind horizon I think most the people here are familiar with an SLA. 😅

Again. It matters what the service is. SLA is typically a guarantee of some sort that the service will do x to a minimal y. It's largely a contract that service will get rendered and keep being rendered for whichever price. It's a sale but instead of good it's something intangible and not defined as what provider charged for that must be entirely fulfilled. Otherwise customer didn't get the service to whichever satisfactions for which the payment was made.

It's important because if you consider a metal host, the service provided is metal machine. It only makes sense that uptime only includes the time it's running after successful post, bios boot to... what?

#

Idk screw all that I wrote literally paragraphs detailing worst infra ever scenario.

#

You should have no infra. There should be no 'internal' place from which issues arise with respect to you.

#

You should try to make 'your service' not 'your server' as in 'infra provided on which service runs on'

#

Containers idk either tbh. Containers sound like they might be used both by you and the host.

Won't work, since escape odes have no relation to rhe code (\n and n) but they represent a byte for most but for unicode(/uFFFF, so \ and n, together need to be replaced by one byte '\n' afterwich the string beyond this point needs to shift over one char., however this is feasible for /n eg but for \octal 2~3 chars 0padded or not, /u4 chars, \x zero padded or not, and there is no way to look up the characters and getting teg code back at best you can char-48 for he and lowercase

Most of these are extremely easy to do, the x one just requires you to read chars for a bit and shift values. It's also implementation defined so have fun.

yeah you also forget the octal ones wich can be either 2 or 3 chars following the , the x ones is also nice because , when used with sscanf , there is no limit on the amount of chars that will be read as long as they are valid hex, so while \xFFFF is actually {byteval 255}FF , sscanff makes 65535 from it but i went the verry long way around after pulling my hair for half a day, string -> char array with every other char a \0, and a pointer array to every first char in the first array so arr2[2] points to arr1[4] , then loop over them looking for '\', if found switch case on the value of the next pointer in the array, and eg for x, read the values of the next pointers aswell , sscanf on each of them, multiply by position and write the value to the first array at the place where the '' was, and fill the next 3 with '\0' , seemed less cpu compared to shifting over the whole array x times accordingly , just to avoid reading 3 dead values or so in the end

Is anyone knowledgeable on nginx? I got a domain, setup some subdomains, everything's working fine. But some subdomains I made are for "future" stuff so I just want to refuse the connection or return a 404 or something when any subdomain that isn't explicitly defined is queried.
Eg, lets say I have domain.com, with subdomains www. , plex. , magic. , and my nginx config already proxies the root, www and plex but not magic, and I don't want it to redirect anywhere else (not even the root/www)

You can just not put the subdomains in your DNS records.

I think I know what you've done anyways, namely that you probably didn't intend to use the store object on line 172 of index.js and should have used a different one - perhaps socket or io at a quick glance?

lament bridge

This is the output of store and the store.challenge function


SessionStore { _key: 'webauthn' }

challenge: function(req, info, cb) {
  if (typeof info == 'function') {
    cb = info;
    info = undefined;
  }
  info = info || {};
  
  if (!req.session) { return cb(new Error('WebAuthn authentication requires session support. Did you forget to use express-session middleware?')); }
  
  var self = this;
  crypto.randomBytes(16, function(err, buf) {
    if (err) { return cb(err); }
    req.session[self._key] = {
      challenge: base64url.encode(buf)

      var user = clone(info.user);

#

Must be haunted, call the exorcist

lament bridge
#

I am sorry you feel that way, believe me or not, I did not use store.on

inner wraith
#

Ah actually I'll give you that after a much better read of that stacktrace, you didn't write it but your middleware contains it

#

You are using this to initialise your app:

const SessionChallengeStore = require('passport-fido2-webauthn').SessionChallengeStore;
const store = new SessionChallengeStore();
const session = require('express-session');
const app = express();
app.use(
  session({
    store: store,
    secret: 'your-session-secret', // Replace with your own secret key
    resave: false,
    saveUninitialized: false,
  })
);

express-session's index.js then does this with store:

  // register event listeners for the store to track readiness
  var storeReady = true
  store.on('disconnect', function ondisconnect() { <-- L172:Index.js - Line of error
    storeReady = false
  })
  store.on('connect', function onconnect() {
    storeReady = true
  })
#

Clearly, whatever require('passport-fido2-webauthn').SessionChallengeStore exposes is missing an expected property, namely the function on

#

AKA: whatever an instance of SessionChallengeStore is isn't compatible with whatever express-session expects store to be for one reason or another

#

So probably time to read the docs for both

lament bridge
#

Yeah, I figured out 😦

inner wraith
#

Incidentally, types are lovely

#

Passing objects about and hoping they all have the right parameters is not, for this reason - but that's js innit

lament bridge
#

So I think one possible way would be to not use the socket.io and webauthn for the authentication, instead just use HTTP(S) then se the sockets once the authentication is complete

inner wraith
#

I've used express before but am not familiar enough with it to give you a helpful answer on that sorry

lament bridge
#

No worries

#

I will figure that out, I just hoped it was possible like this

lament bridge
#

@inner wraith mate, thank you so much, I figured it out, the problem was, I had to socket.handshake which contains the session detials

inner wraith
#

No problem

spark temple
#

@lament bridge for the future to read the stacktrace to see where the error is happening is to focus on these lines here;

TypeError: store.on is not a function
    at session (/home/marcell/PagerCast/server/node_modules/express-session/index.js:172:9)
    at Object.<anonymous> (/home/marcell/PagerCast/server/server.js:23:3)

As you can see, the store.on is being called in your express-session node module. It is invoked in your server/server.js on line 23. So, you can read that as you most likely configured something incorrectly before invoking the node module.

#

i think that since html elements mostly inherit stuff from their parent , placing stuff like font to be used over the whole page by default is best placed in the body {} , or possibly even the html{} (if you use one)

Yea, something is causing it to flow past that element. What you have open is the head section of the HTML which isn't visible as scripts, meta information and other resources are provided. In the <body> you will have the content that is actually displayed. So, on the right hand side of your browser, where the DevTools are open, you have a dotted square with an arrow. If you click on that and then click on the footer on the page, it will open up the HTML there. On the furthest right, it will then give you the CSS Styles (aka the Styles) that are applied to the footer, there's also a Computed tab. This tab holds the information that is computed because of the order of operations when dealing with CSS ultimately can only have one style be applied by (aka, you can't have two classes applying different background colors).

#

Or you know... you could apply the correct CSS instead of trying to compute it to keep it in bounds.

#

Oh, not saying that computing it is always wrong. Just in this case, it doesn't make much sense and can hurt performance as time goes on.

Hello, starting off sorry if this post has to be taken down. I am interested in seeing what you guys think about an idea I had and to see if there are any other similar products.

The platform is called Backendo

Backendo is a platform similar to frontendmentor.io where you can find Backend related challenges based on your skill lever (Begginer, Intermediate, Advanced).

Backendo also offers a paid tier (Backendo PRO) which is 5$ a month or 50$ a year, the pro subscription offers complete tutorials and solutions for all challenges on the platform in 4 different frameworks (Next.js API Routes, tRPC with Next.js, Nest.js, Express.js). Pro also offers a full suite of Test UIs, Test UIs are little frontend applications to test your API, for example a Test UI for Authentication will contain a form which makes a request to an API the user provides, and the User's API will have to match the UIs security requirements (for example using an httpOnly cookie instead of storing the auth token in localstorage). Backendo may also offer a full platform where recruiters can find you, but this is only an idea and not something set in stone.

The costs of running the platform will be very low, and scale as the website grows (The core tech stack relies on Next.js and PlanetScale).

Would you buy a product like this if you were a begginer? Again I want to say sorry if this kind of post is not allowed.

I don’t think I would ever pay for the Pro, there are already so many learning platforms with massive catalogs. What you described sounds a lot closer to something I’d signup for free, but not paid.

Maybe you can ad support it somehow, especially while you are starting and don’t have much content.

Neovim also uses basically the same Vim controls but is easier extensible since it uses Lua for plugins and configs. And with NvChad, LazyVim or AstroNvim you have very much a basic config for turning Neovim into your IDE.
And with this series of videos and that plugin (which only works in Neovim btw) you can maximize that power to make you a 10x Developer. It's a steep learning curve, buz once you understand the basics it gets much easier and you're getting blazingly fast.

What does federating mean? I've heard it in so many contexts

silk eagle
#

usually what that means with social media is:
the network of nodes syncs new data with eachother, usually in separate data stores on the network like in atproto.
I believe the movements of the network do have to make sense cryptographically and be signed by the users that make them
and then individual networks in it are able to filter it however they want

in the case of mastodon and other ones, including mine that use activitypub is more like email.

"hello I wanna follow @gabboman@app.wafrn.net" => "hello app.wafrn.net i am @user@otherserver.com and I am following to gabboman" = "hello I am subscribing to gabbos newsletter"

#

internally it works more like that. when you post something your server sends the post to everyone that you're subscribed to. more or less

atproto is something different that I havent look at yet since it still makes no sense to connect with it. But people a lot more clever than me has trashed it a bit tbh...

I initially used the common lorem ipsum placeholder text, but that made the test flawed as browsers are good at caching the result if the same operations are executed right after each other. So I use this function to prevent caching by making it random

At least try format your code before posting it 🙂

    //Given a string s, find the length of the longest substring without repeating characters.
    //EX: 'abcabcabb' --> 3
    //EX: 'bbbbb' --> 1
    //EX: 'pwwkew' --> 3
    //EX: 'oboadefk'
    public int lengthOfLongestSubstring(String s) {
        HashMap<Integer, Integer> map = new HashMap<>();
        int r = 0;
        int l = 0;
        for (int i = 0; i < s.length(); i++) {
            for (int j = 0; j < s.length(); j++) {
                if (!map.containsKey(s.charAt(j))) {
                    map.add(s.charAt(j), r);
                    r++;
                }
                if (map.containsKey(s.charAt(j))) {
                    map.clear();
                    break;
                }
            }
        }
    }

so the approach here should be a 'sliding window', where you have 2 pointers, one for the 'start' of the window and one for the 'end' of the window. as you increase the 'end' position, check for duplicates in your store of characters (using a hashmap works iirc (but dont force that if its messy to work with)). if there's a duplicate, I believe the trick is you just increment the 'start' position of your window until the duplicate character is gone.

Bit late to this but no: on paper there are killer single board computers out there, but 1) customer support is few and far between, 2) the Linux kernel may or may not even support the hardware, requiring third party binaries to work, and 3) the great thing about the raspberry pi is you can easily Google any issue with it, and chances are someone else has had the problem and done troubleshooting.

If you wanted a small, affordable, computer you should be looking on eBay for business surplus PCs, Small Form Factor PCs from Dell/HP/Lenovo with i5-6500s and 8GB+ of ram can be found for $~100 CAD on eBay these days. If you want something smaller you can get a Lenovo M700/710/900/910q which is a 1L PC of equivalent CPU generation

I was planning on doing a bunch of different projects from like custom drones to home automation and securityor robotics like the Boston doggo etc. And I figured I could probably use different pi's for different things and use different types of sensors and things but recently I've been seeing a bunch of different videos on a bunch of different little computers talking about "this is so much better than a raspberry pi" so I started wondering of there were better alternatives in general to pi for various different projects and compatibility with 3rd party products like sensors, cameras, displays, motors etc.

Tbh, it sounds like a Pi is overkill for most of your requirements. For a lot of home automation you'd be more suited to using COTS zigbee relays and temp/humidity sensors with a USB sonoff gateway. For everything else use NodeMCUs running MicroPython/CircuitPython and only use a Pi 4 where a full OS is necessary

Can you show us knowledge_base.json? I think I can see what you're doing wrong but there's no way to reliably infer structure from your code. (Ah wait I can do so with L45)

#

I'll also say that the whole for q in knowledge_base["questions"] thing you've got going on in get_answer_for_question screams "use another object, not an array" - that way you can skip iterating over the lot every time you want something and just pick out your desired key.

#

Wouldn't knowledge_base[question]["answer"] be much a much more convenient way to access an entry by a known identifier?

#

I'd inline all of those helper functions and simplify the data structure in knowledge_base to eliminate the last one.

bruh it is a dictionary "key error", you are storing the question as a question string "who are you?" : "answer".
and then when you are looking up the dictionary you are searching for the literal string "question" and not the question that is "who are you?".

silk eagle
#

yeah... that's an annoying way to store questions in my opinion but if you want that to work you'd want to iterate through like for question in dict.keys(): answer = dict[question]

#

alternatively you could just make a JSON list for your questions. example:

[
    {
        "Question": "Who are you?",
        "Answer": "I am a bot"
    },
    {
        "Question": "Question 2",
        "Answer": "Answer 2"
    }
]
#

which would be accessed like:

for question in jsonData:
    print(question["Question"])
    print(question["Answer"])

Are you giving them S3 access directly? If so your only real option without using a more intelligent approach is to use an S3 Event notification to have uploads trigger a Lambda function/SNS/SQS to an instance for the same to scan the contents.

Else... don't allow uploads, specifically do not allow binaries if you must allow uploads, have your app server you upload to require them to be of a specific type and inspect them (don't rely on file extensions, they're nearly worthless), if images or video are expected deliberately re-encode them first to destroy anything included and you can shrink them while you're at it...

tbf IPv4 really should've been deprecated years ago. The only reasons it's still around are that an IPv4 addresses is ez to remember, and no matter how old the device/OS, it will work with it. But it's not like IPv4 to IPv6 reverse gateways don't exist, in-fact the XBox online services will run you through one if you connect to them using IPv4 instead of IPv6...

inner wraith

Deprecated?

#

Perhaps the day BGP dies

grizzled steeple
#

Can you name anything still relevant that the average user interacts with that doesn't support IPv6?
I know that some ISPs already won't give you an IPv4 address even if you ask for one. IPv4 outward traffic will be routed through an ISP level NAT on a single IP address which does cause issues for peer to peer connections on IPv4...

I still find it stupid. IPv6 has been around for years now, you'd think the problems would've been solved by now. No, instead they'd rather focus on how to distribute the few remaining IPv4 addresses...

#

well, except for the giant hard to remember addresses 'cause that's kinda intrinsic to such a large IP pool

Because I'm using several small instances for resiliency it'll up my costs by 86% though I am aware that I'm an outlier there. AWS was still cheaper than Google Cloud and especially Azure by a significant margin.

#

T3/a.nano and micro instances just got a lot harder to recommend though if you only need a few and expect to need S/PaaS cloud features it's still likely your best option.

#

Azure Australia still costs like 5x more for small deployments, I don't really get how anyone can look at their instance prices and decide on it without being forced to by a non-technical business unit.

I mean yes that's why Azure's shoved upon people, though I'm going to doubt that it actually makes security that much simpler tbh.

I'm probably about to set myself up a tenant on it anyways for Exchange+AzureAD because that's stupid cheap.

anyone know a bit of typescript? Ive hit a roadblock trying to figure out a odd asf bug applying colours in my VSC extension.

My extension looks at &c &a etc. etc. and gives them acolour, for ex: &aHello , would make Hello red.

Recently I added a way for you to specifcy a colour with &x. For ex: &x&f&f&f&f&f&f is #ffffff . However, for whatever odd as hell reason, that decides to make it so everything is not coloured? Without any errors.
