pgo··on Stanford researchers find only 3% of HTTP runs on port 80 [pdf]
This is expected right, HTTP is not only used for human consumable web applications but for API servers as well

The bulk of these would just be embedded devices running multiple API services, like port 7547 highlighted in the article is your typical TR-069 service running on most consumer internet routers

I would argue most non-API/non embedded devices web applications would still be running on 80 and 443

pgo··on How to build software like an SRE
Agreed, If you have retries then you also need circuit breakers
pgo··on JetBrains invites developers to join the Fleet Public Preview Program
Yes, palash [at] dyte.io Thanks for the invite
pgo··on JetBrains invites developers to join the Fleet Public Preview Program
Would you happen to have an invite for zed.dev ? I typically have 10-15 VSCode windows open and have been looking for an performant but modern IDE
pgo··on New credit card rules in India: recurring card payments to be affected
It's a one time authorization
pgo··on Google hits undo on limiting JavaScript capabilities in cross-origin iframes
No, this is about alerts from cross origin content, like from an iframe that loads from a different origin than the parent page
pgo··on Google is capping Meet’s group video calls to an hour for free accounts
Try our free demo (uncapped for the near future) with collaborative plugins at demo.dyte.io (YC W21)
pgo··on Show HN: Zoom / Teams Open Source alternative for online learning
Yeah there is, the video chat is not P2P, everyone uses the SFU model where all your media goes through daily's server, so they have to pay for the instances and the bandwidth
pgo··on Show HN: Free open-source isolated browser for security
So under the hood it's chromium headless and you are streaming screenshots back using an extension

Curious why not run normal chromium and vnc the whole screen back using a web client such as novnc, would have solved most of your "Normal Browser UI things not yet implemented"

pgo··on Dependency Confusion: How I Hacked Into Apple, Microsoft and Other Companies
There are no typos here, the root issue is package manager preferring public packages of the same name over private ones

Didn't we get support for it last month

pgo··on What's in a Linux Executable?
Cool diagram. Putting the shellcode in headers is very innovative. I didn't have too much assembly knowledge to trim it further during the competition.
pgo··on What's in a Linux Executable?
I once wrote an ELF by hand for a CTF challenge. The challenge was to have an shared library such that when it is passed to LD_PRELOAD it spawns a shell by execve

LD_PRELOAD=<ELF> /bin/true

The constraint being the ELF needed to be less than 196 bytes so obviously it could not be created by gcc. In the end I could not believe it ran, considering the amount of hacks that I had to do to trim it to 193 bytes.

pgo··on Blockchain, the Solution for Almost Nothing
Source for this ? I can only see mentions of plans implementing this, not of it being actually deployed
pgo··on Breaking Samsung Firmware, or Turning Your S8/S9/S10 into a DIY “Proxmark”
The rooting process is actually very standardized. On most of the phones you just have to patch a su manager tool called Magisk[1]. Its open-source and been under a lot of eyes.Also the dev works at apple and is a community favorite.

Custom roms are a lot more risky, there are 100s of different flavors made by relatively unknown developers and even though they are technically open source, I find it highly unlikely that none of them contain malware. I mean you can introduce a memory corruption bug in few handful characters, these custom roms are practically unauditable.

pgo··on How to contact Google SRE by dropping a shell in Cloud SQL
Well its called managed infrastructure for a reason.
pgo··on How to contact Google SRE by dropping a shell in Cloud SQL
Legal, encouraged and rewarded. Bug bounty programs allow hackers doing these kind of explorations. Although most programs advise you not to do anything once you get code execution as it might break things on production, so the final part where they started intercepting traffic might not be something I would do, but they took a calculated risk, that this is is docker container that does no critical work and it would be interesting to see if we could break out of it. So that's fine.

You can read up more of such reports at hackerone.com/hackitivity or just searching about bug bounty writeups for X organization

pgo··on TSA considers new system for flyers without ID
Similar thing happened to me, I had 1/8 ounce weed in my hand bag I unknowingly packed, flew in from Los Angeles -> China -> India. I went through rigorous security checks with police dogs and fully body scanners at both LA and China. I panicked when I opened my bag when I reached home.
pgo··on Apple takes legal action against small company with pear logo
How, why doesn't a judge throw out apple's case in the first hearing itself. What legal blackmagic can make such a one sided case drag out
pgo··on IBM completes successful field trials on Fully Homomorphic Encryption
Its less about structure and more about use cases. In my opinion there are only two major uses of data collection by organizations - Machine learning training data and targeted advertisements. A federated fully homomorphic system will allow these companies to train their models without invading personal privacy.

It will also allow organizations to train models collaboratively in a privacy preserving way, which if you think about it has lot of consequences.

pgo··on Covid-19 is causing a wide range of disorders in the nervous system
No disorders, No family history of diseases except diabetes in a few older ones. All of us got over corona with just a little fever except him. Well we cant even say with confidence what is happening with him is due to corona, it could be two different diseases coinciding at the same time.
pgo··on Covid-19 is causing a wide range of disorders in the nervous system
My family got corona positive last month, around the same time my brother started having some neurological issues. The doctors after seeing the MRI did not detect any issues. The same was confirmed by other radiologists and multiple other MRI scans over the month. Yet he faces these issues: nausea,headache,confusion,weakness,ataxia (unsteady walk) sensory changes, including numbness or tingling,trouble with vision (one eye doesn't move / change focus as much as quickly as the other eye ). All these issues point to a brain infection yet none is detected.
pgo··on Firefox Android: Camera remains active even when the phone is locked
Sorry but you make it sound like its four independent actions which lowers the overall probability. While in reality this whole sequence of actions is a very common thing for a user to do.

Really informative comment.
pgo··on India coronavirus: The 'mystery' of low Covid-19 death rates
Few isolated incidents mostly in slum areas where rumors spread of a government conspiracy of targeting muslims. This government's anti-minority image did not help.

pgo··on India coronavirus: The 'mystery' of low Covid-19 death rates
There is no good metric for comparing test rates as well, tests per million makes no sense when a lot of states within the country have almost zero cases. India's less than 5% positive ratio on tests even in hotspot regions do not indicate a massive lack of testing.

You got the facts completely wrong, India started the lockdown when total deaths were just 10 !

pgo··on Stripe raises $600M at nearly $36B valuation
The Indian rollout has been extremely slow, Stripe launched the beta in December 2017 and still hasn't come out of preview. What kind of challenges did you face that delayed the launch by more than two years?
pgo··on Valve and HackerOne: how not to handle vulnerability reports
What you are saying makes no sense, why does android only accept the self signed certificate when it redirects from http and not for direct https connections. Can you provide a source, a stackoverflow link maybe where this problem is discussed ?
