tmottabr··on Twitter/X migrated to Cloudflare, bypassing Brazilian block
They will defend their customer interests by staying able to do business in Brazil..

Lets remember that Twitter is not their only customer..

So if twitter has problem with some country justice it is their problem to solve, not a problem to be shared with every other Cloudflare customer..

Also, i doubt that they are making more money from Twitter then every other customer in Brazil added together..

tmottabr··on Twitter/X migrated to Cloudflare, bypassing Brazilian block
i doubt it will require null-routing Cloudflare..

they will probably get notified to block twitter in Brazil and will likely comply.

tmottabr··on Ask HN: How does my school block DoH?
VPN are easy to block even if they run on HTTP\HTTPS ports and are encrypted

Connection characteristics for VPN connection are very different from a legit HTTPS connection..

They cannot prevent you from connecting on the port, but HTTPS connection does not stay connected for long and any long lasting connection can be dropped by their router preventing you from keeping the VPN for longer then a few seconds\minutes.

tmottabr··on Ask HN: How does my school block DoH?
Instead of all that..

Please use a VPN, this will circumvent any local limitations..

If they block VPN services you could try using a VPS to configure your own server.

That unless they drop connections they detect as behaving like a VPN, something those devices can do..

But i can say for sure that if i was the manager for that network and i caught you circumventing the protections in place you would be in trouble...

If you want to access stuff that is not authorized in the network use your cellular connection for that.

Will just add one thing that i guess i did not made clear...

I bet you that both people in the west society and in Russia society condemn those actions..

It was not those society that allowed those things to happen.. It was the government...

So I am not judging either society, i am judging both governments..

The difference between west and Russia is the general population access to know what happened and their ability to held the government accountable..

And on that aspect i agree that the west is better then Russia..

But again, this is not what i am judging.. i am judging the government actions and motivations..

And both governments allowed those things to happen and both handled the problem after it came out and only enough to do damage control without making any real and lasting changes...

The only difference is that Russia does it by hidding from their people and\or lying to the people and west does it by throwing soldier goats under the bus but saved the ones that allowed it from any major repercution..

And looking trough that aspect i fill that both are equally bad..

Everyone know that not everyone in the west is to blame for those things happening, the same way everyone know that not everyone in Russia is to blame for what Russian soldier do...

tmottabr··on Telegram will start moderating private chats after CEO's arrest
I would agree if as soon as this happened and the higher ups were made aware of they had took action to stop it immediately.. But we know that is not what happened..

I would agree if each and every person involved had faced repercussion regardless on how up they were in the command chain, but again it is not what happened..

Come on.. For this people to be so comfortable doing those things to the point they took photos of themselves doing it was because they were comfortable enough doing and sure there would be no repercussions.. And if the soldier were this comfortable to do those then and this sure there would be no repercussions i can almost guaranty you that it happened a lot more then what we know..

And again, there were no repercussions until the things were exposed.. It means that people did those things, and other people saw those things happening and did nothing about until much later when it got exposed to the public.. Then they threw some soldier under the bus to save face and moved on with their lives..

I will give you that in the west at least those things to get exposed and something happen even if only to the people at the bottom of the chain.. in Russia since they control the media they will just hide it, deny and just not care.. But both allowed it to happen and and only took action do damage control later when they needed.. Sorry if i find both equally nasty..

And those things surely makes me wonder how many more times other people did the same thing and hide it properly either because they knew there would be repercussions if it got exposed or because they received help to hide it from someone that knew..

Or if the higher ups that got away without repercussions ever allowed those things to happen again as long as there was no evidence left behind..

Sorry if i am not moved by half a dozen of peons being used as escape goats to save the ass of the higher ups that authorized all this either well aware of what was being done and not caring or not caring to find out to have plausible deniability later..

And not that you will believe but i honestly would not consider moving to the united states any more then i would consider living in Russia, Iran, North Korea, China and most of Europe..

And i will leave at that.. If you have not gotten it by now you will never get it..

Oh Yeah, lets tell that 14 years old girl that her being rape and murdered with her family is fine because the soldier were held accountable..

But i was thinking more on line of who knows how many times more that happened and it was successfully covered up like they tried, and failed, to do in this case..

Or on the lines of the Abu Ghraib prison where torture, sexual assault, rape, murder and desecration took place because the government authorized "enhanced interrogation techniques"..

A case that had the US government arguing that humanitarian laws like the Geneva convention did not apply to US interrogators oversea.. And that required a supreme court ruling to tell then that those laws indeed do apply to then..

And the people that were held accountable just were because journalists denounced what was going on and in the end they only prosecuted the soldiers, the higher ups that approved it did not face any major consequence..

This one have some pictures for you since you wanted some:

https://en.wikipedia.org/wiki/Abu_Ghraib_torture_and_prisone...

US also used "enhanced interrogation techniques" in Guantanamo Bay Detention Camp, again authorized by Bush administration. There is no evidence of rape here but not that it make it much better.. Had already mentioned that in case you missed..

https://en.wikipedia.org/wiki/Guantanamo_Bay_detention_camp

Anxiously waiting your mental gymnastic to tell us how the US disregarding the international humanitarian laws and Geneva convention is fine..

West and the Russian are two sides of the same turd (and the rest of the world is not far behind).. the only difference is that the west want to play righteous and have to save face so they work to cover it up while the Russians just don't care and do it in the open..

In the end, you can stand in your made up pedestal as much as you want and think the west is better, the rest of the world knows the truth you like it or not..

tmottabr··on Telegram will start moderating private chats after CEO's arrest
Pictures exactly no, but i can show you evidence that it did happened..

Rape and murder in Iraq: https://en.wikipedia.org/wiki/Mahmudiyah_rape_and_killings

Murder in Afghanistan: https://en.wikipedia.org/wiki/April_2003_journalist_killings...

the war crimes pages for the us and uk has more stuff covering the middle east invasions: https://en.wikipedia.org/wiki/United_States_war_crimes https://en.wikipedia.org/wiki/British_war_crimes

Hell, if you look for you will find dozens upon dozens of cases of innocent being murdered by law enforcement WITHIN THE WEST, why the hell would you think that it is not happening in foreign soil as well, where there much less oversight..

tmottabr··on Telegram will start moderating private chats after CEO's arrest
As recent as the west invading Iraq because fake chemical weapons that were never found and turn out they knew they never existed all along..

As recent as the west invading Afghanistan to fight Taliban, that the west had a hand in creating in the first place to fight the soviets in the 70s..

As recent as the tortures that took place in Guantanamo..

west and Russia are two sides of the same coin, same shit... The history is told by the winners and west is often the winners.. Does not mean they are always the right ones..

So let me draw it just to make it super duper clear..

West should indeed be worries about Russia, but do not expect the rest of the world to have any sympathy to you when you did the same thing to us at some point or another..

And to be really honest.. at the moment global south is much more worried about the west pushing back on China rising influence on the global south then whatever Russia is doing in Europe..

We are worried about what the west will do now that the parts of world decided to move away from the dollar for international trading to prevent the US from economically bulling other countries like it has always done with support from the rest of the west..

We have as much, if not more, to worry about from the west then we have to worry about from Russia..

tmottabr··on Telegram will start moderating private chats after CEO's arrest
That is not at all what i am saying..

What i am saying is that westerners countries act like the world is ending because Russia is doing those things, that Russia is the big bad and that everyone should be scared..

But when they did to the rest of the world it was just business..

It was just pointing out the hypocrisy of westerners countries.. When they do it, it is ok, when others do it, it is a problem..

Most of the global south think westerners countries overall all are all big bad as much as Russia is..

The point that was made in this thread was that everyone should be worried about Russia doing this things while the response was the question on why should the global south be worried about it?

Specially when what Russia is doing is not news to us, we being trough all that time and time again..

Now, to be clear, i don't disagree that Russia is the big bad right now, but westerners countries are not any better..

And to be extra clear, i understand we do face consequences for stuff that Russia is doing to Ukraine, but the same way we face consequences of what westerners countries do all over the world.. So for us this is just another day dealing with the crap the world trough at us..

It would be good if Russia behavior taught westerners countries to not do those things and their behavior changed in the future but that is wishful thinking, we know that will not happen any time soon..

tmottabr··on Telegram will start moderating private chats after CEO's arrest
harassing other countries, starting wars, etc..

Russia is doing it now to westerners countries the same way westerners countries have done to the entire world..

Lets not pretend the last two world wars and significant portion of local wars were not started by westerners countries after all..

tmottabr··on Telegram will start moderating private chats after CEO's arrest
And westerners country have done it to both Russia and pretty much to the entire world for decades..

They are only tasting a bit of their own medicine..

tmottabr··on Telegram will start moderating private chats after CEO's arrest
They have, but the limit of people in a group is significant lower then Telegram, at least for signal\ws, dont know how matrix handle this.

Telegram allow 200000 members in a chat group.

Signal on the other hand allow only 1000 and ws limit is 1024.

It is possible to have group chat encrypted, but this does not scale very well and allowing new members to see older messages also is trick, although both are possible.

EDIT: i just checked for matrix and while they do not impose an limit their docs do indicate that there are performance problems for very large groups with tens of thousands of members, that while much bigger then signal\ws it is still much smaller compared to telegram.

tmottabr··on Telegram will start moderating private chats after CEO's arrest
New messages yes, but old messages no..

The typical way group chat encryption is done is the client generate a key per message, it use that key to encrypt the content of that single message.

Then it will encrypt the message key with personal key for each member of the group, and it can only do that for current members of the group.

Once you receive a message the client will use your personal key to decrypt the copy of the message key encrypted with it, then use the message key to decrypt the message.

The problem with this is that, first it does not escale, the larger the group gets the harder it is to encrypt the messages because you need to encrypt the message key with more and more personal keys, this make the work load bigger and the message size bigger as well. Telegram support very large groups that make encrypting groups not practical.

Also Telegram allow you to see older messages sent before you join the group as those get stored in the servers, if you join the group later then for older messages the per message key will not have being encrypted with your personal key so you cannot decrypt it, thus cannot decrypt the message.

You would need to either store the per message key unencrypted in the server and make encryption useless as the server would be able to decrypt it, have the client from some older member of the group re-encrypt the per message key for older messages and send to new members or the simpler approach that Telegram took to not encrypt it at all.

tmottabr··on Starlink U-turns, will block X in Brazil after all
they didn't..

Bolsonaro has his supporters and a share of then did ask for a military coup, but those are minority..

Majority of the country was against a coup.. But popular support changed nothing..

The military coup did not worked because the US send messages indicating they would not support it, so the air force and army commanders backed out of it..

tmottabr··on Brazil Court votes unanimously to uphold X ban. Users switch to Threads, Bluesky
The president in Brazil does not have the power to take down content just because he want..

This was the justice system that ruled that some content should be blocked, and this decision can be appealed bu the person that was blocked..

The problem here is that twitter, that was not a party in the case, decided they wanted to appeal, something they cannot do in Brazil legal system..

tmottabr··on Brazil Court votes unanimously to uphold X ban. Users switch to Threads, Bluesky
not at all..

twitter servers are in the US yet they are having problems in brazil..

If server are in space and company refuse to abide to each country laws they will have the access to their servers blocked just the same..

tmottabr··on Brazil Court votes unanimously to uphold X ban. Users switch to Threads, Bluesky
in theory it is.. but the only site that implement their protocol is bluesky.social
tmottabr··on Brazil Court votes unanimously to uphold X ban. Users switch to Threads, Bluesky
Bluesky have contact information in their site..

But Brazil justice is already in contact with then, as long as they offer a place for justice to send court orders and comply with then, as they have done so far, they wont have any problems..

tmottabr··on Starlink Defies Order to Block X in Brazil
And what i am saying is that i do not agree with that take..

While a right wing government is not guarantied that Elon will be able to buy Sigma Lithium, i am 100% sure that a right wing government will work to try block or at least delay as much as possible the acquisition by BYD..

Specially in the unlikely case that Trump win the US election, remembering that Elon is supporting him.. US will not only support blocking China from increasing their foothold in the region, they would likely pressure Brazil for it..

It might even happen with Kamala but to a smaller degree..

tmottabr··on Starlink Defies Order to Block X in Brazil
Lula being aligned with Russia is not news..

But Lula will not move to prevent BYD from buying Sigma Lithium or to help Elon buy it instead.

While a right wing government is not guarantied they will help Elon there is a much higher chance of it..

tmottabr··on Starlink Defies Order to Block X in Brazil
Who said anything about stopping doing business with china??

What i said is that Elon expect that a right wing government would block, difficult or delay this single Chinese company from buying Sigma Lithium to help him to buy it instead..

Australia is doing the same think right now.. Australia is currently the largest exporter of Lithium in the world and Chinese companies tried to buy some mining companies there but the Australian government prohibited.. They said the Lithium mining is too important to the country and that they do not want China to control it..

There is some investigation going that China might have went ahead and acquired the mining companies in Australia indirectly via third-party companies and last i have seen Australia government had ordered those companies to sell their share or else they will seize then..

China is still one of the largest Australia trade partners, that did not stopped it from blocking the mining company acquisition..

tmottabr··on Starlink Defies Order to Block X in Brazil
He did more business then expected but he did not miss an opportunity to speak ill of china.

There were even multiple letters from the Chinese embassy complaining about stuff he said..

China even blocked buying meat from Brazil for a while with the excuse of mad cow disease..

So regardless of how much business Bolsonaro did with China, he would be more inclined to help Elon in blocking China then the current left wing goverment is..

tmottabr··on Starlink Defies Order to Block X in Brazil
Not only that..

Both Tesla and BYD had negotiations to buy Sigma Lithium, the largest lithium mining company in Latam, where the world largest lithium reserves are..

Bolsonaro, and the right in general, is known to be anti-china and could help blocking BYD acquisition, that would favor Tesla that would be able to buy it cheaper then if he has to outbid BYD...

Cutting the Chinese access to latam lithium would also harm their expansion plans and slow their grow.. That would also favor Tesla as the Chinese is owning the market in many developing contries and are growing fast even in Europe..

Even in the US the Chinese EV are a problem to Tesla, to the point the government quadrupled the import taxes on Chinese EV..

tmottabr··on Starlink Defies Order to Block X in Brazil
Latin america have the world largest Lithium reserves, specially accross Argentina, Bolivia and Chile being the three largest and Brazil being the 7th..

The largest lithium mining company in the region is Sigma Lithium..

Tesla was negotiating to buy the Sigma Lithium but now the Chinese BYD is the favorite.. [0] [1]

China companies are currently owning the EV market in Brazil , and many other developing contries, and they have plans for both cars and batteries factories in Brazil, but they need access to lithium for that and so they are going for the lithium mining companies as well..

Musk not only need the lithium but he also want to block the grow of Chinese companies that are owning the market in many developing countries where Tesla is not present and are even growing fast in Europe..

Musk expect that a right wing government will align with him, and be in favor of blocking China and that would open the door for him to buy the mining companies instead..

tmottabr··on Why So Many People Are Going "No Contact" with Their Parents
i will divert from the other and say that unless you experienced both it will be hard to say...

i am from latin america where families keep closer contact trough life and that is all i have experienced personally..

I think you would need to experience both to say what is better and even then it will change from person to person..

But i can say that it does come with its share of problems..

tmottabr··on Self-Hosting DNS
No, it is not the wrong tool for the job..

It is one tool that is available in our toolbox that we might use or not.. and it is one perfectly valid way of doing it.. It might not fit all workflows or all use cases but that does not make it bad or wrong..

Also, not every endpoint can have ad blocking done locally and having it at the DNS level is a great alternative for those cases..

I honestly use both, all my browsers have local ad blockers to prevent the DNS query from being done in the first place, yet i still have DNS level ad blocker to cover other devices, like TVs for example that now are filled with ads and do not have a method for blocking ads locally..

Also solutions like AdGuard do much more then just ad blocking, like i already mentioned about google safe search, you could just disable the ad blocker and it would still be a great tool to have and i personally consider a must have when you have young kids starting to use the web.

You are within your right to not like this type of solution and are free to not use it in your networks, but stop making BS claims that is the wrong tool for the job or that it is the wrong way of doing it..

What i like most about ad guard home is that almost all configurations can be customized per device.. So if you have some workflow or some device where dns blocking is causing problems you can just disable for that device and still have it for the other devices that need it..

tmottabr··on Self-Hosting DNS
Don't know what shared truth you are referring too.. truth is totally relative...

I have stuff that i can only access inside my home network, so here the truth is one.. Out in the internet those same addresses do not exist, so out there the truth is another..

This is also the same for most, if not all, enterprises, there is always stuff that can only be accessed either on the internal network or via VPN..

There are address that point to different endpoints depending on the network you are connected, and this is by design, again the network wide google safe search is an example.

Same thing for streaming services and CDN's, the same address will return a different endpoint depending on your location..

This happen even for direct IP address without using DNS, Quad9 for example have dozens of servers that provide service to the address 9.9.9.9 for their DNS Server, so depending on your location the same IP address will connect you to a different server that is located closer to you to ensure fast access.

DNS like anything in the network and in computing in general can cause problem if not done correctly.. But then the problem is how it was implemented not the dns blocking or redirecting functionalities on themselves..

tmottabr··on Self-Hosting DNS
DNS is highly distributed.

I doubt the current infra would have any problem handle the load even if all individual devices had a local resolver.

tmottabr··on Self-Hosting DNS
DNS and all the overall infra should do whatever the owner of the infra want it to do.

If i as the network admin don't want you to access some site i will block it, and blocking it at DNS level is one of the ways i have to achieve this and if i catch you trying to circumvent it you will be booted from my network in no time.

That is what local DNS servers are for and what solutions like Pi-Hole and AdGuard Home were desinged to accomplish..

There are many legitimate user cases that require you to mess with DNS. example, you can force google safe search in your network to all devices, google own instructions are to create a cname redirecting www.google.com to safesearch.google.com at your local DNS server.

So no, block or redirecting stuff in my DNS not only is not evil, it is required in many cases.

If you are trying to do something that is being blocked in the local network either talk to the network admin and explain why you need to do that and check if he can fix it for you and if he cant\wont then go do it somewhere else..

Also, most, if not all, the large enterprises do dns level blocking, as they should.. Go try work around this and i bet you they will call you out, insist and you will be job hunting in no time..
