Search - "whatsapp update"
https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

24. I expect to check what goes on today in the city and give her the
location to meet and time.
25. I enter office and immeadetly get caught up in meeting planning, dev
questions and the meeting itself because the project is on edge.
26. We have a 5hours long meeting where people go on and on and on.
27. 3h later in the meeting:
my brain was fried and around 12 i go to lunch with some people.
28. Meanwhile the city is turning into a rainy mess of a shitty day. No

47. She goes quiet.
48. 2h later we finish the meeting. Meanwhile QA foudn a bug we need to
fix because why not.
49. I got 30 minutes to find the bug and fix it before I need to go to
uphold my word.
50. I find out what to do, but it might break a lot of other things
without careful test and implementation. Collegues says he takes it.
51 I feel bad but I need to go. I even leave earlier because otherwise I

I already have some with her.
60. I feel lost right now. But my head says I put too much stress on
her, And i fucked up with the planning. I should have been more precise.
My head also says that i am putting myself into the victim role, which
is wrong always. Should I continue to reach out to her? Is there
something I could do still?69
Why Whatsapp... Whyyy?? Life was so simple with you!! No stupid duck faces, no selfies, no freaking location updates of people I dont care about... Why did you have to go snapchat on us!8
Whatsapp: "How about you update your browser?"
How about you fire your whole fucking team of genetically engineered super-retards, that is making whatsapp shittier with ever recently rotten braincell you guys claim to have, and just let me use your shitty spyware I need to use for the time being. Fucking hell don't you even dare pulling that bullshit excuse on me when my browser is based on chromium Aka the fucking same browser engine that is powering google chrome. Just for once stop playing along with google, take your update and put it where the sun doesn't shine, you data-whoring deadshits.9
Note to self: never EVER buy iPhone again. “It won’t stutter after a year”, they’ve said.
Right now my 6s is just one big overheating piece of mess. Right now I have to charge it 3 times a day. Resprings randomly. Very often discharges 2% per minute. All the time lacks memory. iCloud picture syncing SUCKS. The Lightning cable is the worst excuse for buying overpriced cables which will break after a half of year. The only plus is a camera, how easy it is to update the iOS, included earbuds, iMesssage (but I use WhatsApp nonetheless) and battery widget.
And that’s it.
If someone says ever again that “iOS is the best operating system, it doesn’t have any issues whatsoever”, I would say “stop doping”, because I don’t see why it’s so great. Just while typing this rant my battery decreased from 25% to 15%19
so I'm here watching my boss' whatsapp blinking "typing..." for 5 minutes wondering of it's bugged, he's drunk or I have to update my CV...3
WhatsApp: Opens in literally one second
Takes few seconds because of that brand new splashscreen -_-
And it looks ugly too ...10
I forgot how exhausting being tech support can be. I tried helping my dad update his WhatsApp earlier. He barely knows how to even use a smartphone, let alone how to update apps. I ofc auto-enabled updates through WiFi, but for some godforsaken reason he isn't connected anymore. So yeah, I've been trying to remotely troubleshoot a phone of someone who doesn't understand there's a difference between an app and the Google search bar, and that you can swipe on phones. ~.~
And if you read this until the end, have a cookie 🍪 and / or a beer 🍺- I'm having one myself now, after this, cheers!2
THE RAT-RACE ARC:
I get a mail 2 months into this fiasco telling me to register on their website and take up another test. I was already over with my emergency and was working my full-time default. (Fortunately I found another internship during this time which was one of the best initiatives I've worked with).
It asks me to register as a new user, take up the test and "share" my results. Not pushing it on insta/fb but legitimately share my test results link to my friends manually like a referral code. The more shares the more marks I'll get in the test. Why the test you ask. Of course to sign you up for the same Whatsapp trickery bullshit.
Luckily these nutcases didn't know they could be bypassed. I simply opened the link in incognito and logged in with my own account and that counted as a point. So I automated that shit.
Surprise surprise. The same fucking "Hello everyone" message into my mail. To my surprise I was relatively lucky to get ghosted after my attempt. This story is quite depressing in general cases. You're supposed to do this assignment shit for 2 months and then they ask for 2000 INR for a training period, past which you are paid between 1000/- and 7000/-. Though I didn't get the chance but I'm willing to bet you get 1000/- per month in a 2-MONTH INTERNSHIP. WTF.
You also have the other option of ranking first in their 3 consecutive competition that they hold. The theme is again to create chunks of their actual outsourced work.
The reason why this rant sparked is because I recently received an email with my results of the aptitude exam that I first took before the Whatsapp fiasco. I imagine they just pushed out a new update to their test thingy and forgot to set it's limit.
THE CORRECTION ARC:
I pushed this message to Internshala. They were kind enough to remove them from their website. I also shot down their Angel and Indeed listings. I sent a strongly worded email counting their con-artist operations and how I've alerted authorities (obviously a bluff but I was enjoying it). They most probably are not affected by this though. They might still be continuing their operations on their website.
I'm sharing the story here with the moral of:
Don't do jackshit if they're not compensating you for it
Always check for reviews before you start working at a place.
Be cautious of bulk messages (and the infamous HEY GUYS!! opening)
Don't do anything outside your work specification at least while doing an assignment.
You're free to question and inquire respectfully about the proceedings.
If you're good at your job you'll get good working place. No need to crush yourself with an oppressive job due to external restrictions.
And if you manage a company, please don't take advantage of helplessness.
There's no good ending to this tale as I have not received a follow-up. Though I want to see scumbags of their calibre shot down without remorse.
Good bye and thank you for listening.2
The same friend from my previous fb rant
sends me this 😑1
Someone on WhatsApp asked me did I like the new update or not ?
Well here is what I replied,
WHAT THE FUCK ?! NOOooo ! already there is Snapchat whose USP is this feature, Snapchat is Snapchat, then they introduced this feature on Instagram that's ok...but WhatsApp should be WhatsApp.
ALL I WANTED IS A SIMPLE PLAIN MESSAGING APP, THAT'S IT !
Now it's wasting my time more, earlier I just used to see Instagram & Snapchat stories in my free time BUT now !? I will see these fucking stories again here on WhatsApp too... BECAUSE I can't help it, it's in our human mind psychology too, we are curious beings, we are somehow bound to open that Status Tab when we will see a green dot ! If it's not true SEE THE NEWS ! NASA just found a whole new Solar System just ~40 light years away ! YES we are curious, we explore, we invent things.
I hope they will roll it back, but NO the ugly truth my friend is people will rant about and forget, and we will end up using it too, hate this seriously ! for instance the new iPhones have no 3.5mm audio jack, WTF ?! well say goodbye to my favourite ear buds ! and buy these FUCKING NEW Monstrously over priced bound-to-buy pair of earbuds if you need high quality audio out.
AND are we bound to be slaves and continue using these features because everyone else is doing so ? NO ! I will use whatever I like the most, I will go back to the roots, may be use those old school IMs and may be ask others to join it.6
!tech . Tldr = last para
I have been doing this social experiment about my interaction with the people for last 7 something years and here are some of the details and observations:
- i graduated college in 2020. All the people ihave met in the last 4 years (related to college ) were connected to me via whatsapp in muted/unmuted groups. During college the interactions were usual but once we all got the results in hand, all the groups were gone quiet. The only interactions were when someone posted an interesting status and the other commented in 1-1 chat. 1-n or n-n chats were completely 0.
My experiment was to not post something for a month and even mute status update so that I don't get to see what they are doing. And a month after , i am rarely even opening whatsapp as there are no chats
I finished my school in 2016. At that time all my schoolmates were obsessed with Facebook, like we would play games on fb , like/comment on posts have group chats etc. There also i got the same results : deleted fb after 12th results and today I don't even remember the names of my batchmates(guess they feel the same about me)
We moved to a different locality in 2011. At the new place, i would initially go to park, play with local guys , chat with this neighborhood girl of my age, went to the same tutions.
Later life happened, studies got tougher, i stopped going to parks, the girl and my family clashed over some topic and we changed tutions later. 10 years past, 2 of the guys are still my homies with whom i get on call every now and then, and the rest people are like , we meet in the streets, say hi and on our way..
My parents got in clash with their siblings amd families when i was like 5 or 6. Since then , the uncles/aunts would occasionally call/meet their would be some fake interactions and meetings but once they woul go away (or we would come back from their house) , everyone would take a big sigh of relief
Moral of the story is :life happens. I would have met 7-8k people in the last 10 years, would be on a daily interaction relation for a period of time and then all gone. New people , new time period and old ones now just a name in contact book.
Its not like i lost every friend , there are around 1-2 people that i interact with on a daily level and 9-10 people who i contacted in the last 30 days, but the point is its just not me who don't wanna interact. Everyone just simply moves on.
We humans pride ourselves of being the "social creatures" , talking about scaling and reaching out to millions of people, when we can't stay in touch of 50 people from our football team or graduation batch or something like that.
And this end brings me to a question for all the 35+ people : how are you all surviving in the world? Is it just me loosing all the touch with my contacts (intentionally/unintentionally) or is it for every one? And is anyone even trying to maintain those relations?are those relations worth maintaining?7
Using WhatsApp beta,
Got a update today , I installed
Saw my contacts, it said "No contacts" invite friend.
Iam like WTF ,what happened to my contacts!?
Now iam thinking on the developer ,who pushed this update!
Guyzz!! did u check the new WhatsApp update??
Similar to snapchat ....
no more permanent status's now😫6
I like the new WhatsApp!!
There I said it.
- Snapchat was practically useless piece of crap for me. No one that matters to me used it. That app is a data hog and battery killer.
- Meanwhile, What'sapp cared enough to be datafriendly to those in developing world. Like, enabling video playing while it's downloading.
- Whatsapp is not a data hog or battery killer.
- Snapchat sucks shit unlessn on ios.
- I hate Facebook because if it's spam and i stopped using it. With new WhatsApp update, I'm less likely to miss out on what is happening with people i actually know. I know facebook owns WhatsApp, but it doesn't really matter.
- No stupid discover ads or promos like in snapchat
