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.
For updates refer the kernel tree: https://git.kernel.org/…/ke…/...

place.
Need to hope that it does not come to this.

27. 3h later in the meeting:
my brain was fried and around 12 i go to lunch with some people.

way I can have a nice walk with her like that. Bars and coffeshops are
just to boring.

Meanwhile I am thinking all kinds of locations and stuff in my head.
30. Havent given her any update since a good morning in the morning.

U know to avoid the lets do it some other time fuckery and then it never
happens.
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
would not be on time.
52. I arrive 15 minutes early. I grab two coffee2go and wait outside,
53. Shitty weather, sometimes rain, sometimes sunny, cant decide what it

55. I wait 1 1/2h
56. I think I should feel stupid, For gods sake its tinder. People dont
give a crap, Enough people around why should I Invest so much into this?
But I dont feel stupid. Because this is how I want it. I dont want
appointments, I dont want safety. I decided for her and I went all in.
57. I send her pics from the sceneray as proof that I waited,
58. I think I blew it. She is still quiet.
59. Friends are asking me for plans for the weekend. I wish I could say
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?68 -
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.

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

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%18 -
Before update:
WhatsApp: Opens in literally one second
After Update:
Takes few seconds because of that brand new splashscreen -_-
And it looks ugly too ...8 -
(Part 2/2?)
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.
WHY NOW:
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.

Hopefully, you already know that the company controlled by the alledged reptiloid subhuman and olimpic testicle juggler formerly known as Mister Zuck My Tits is not to be trusted.
But as is always the case in this bitch, I've been forced into cowjizz flooded swamps' worth of stinking shit platforms for the sake of avoiding isolation.
And so, I've just found yet another way in which Facebook **THUNDERSTRIKE** ... the company, not the geriatric ward, is one of the CROWN ACHIEVEMENTS of human civilization.
Let me tell you something: some people are fucking broke. Hell, some people sleep on the streets, live on scraps, and willingly engage in acts of public defecation when provoked. But I'm not even talking about them no, just plain *broke*.
And so imagine being that guy who doesn't really use his phone much, except maybe for sharing cat pictures with mom because that's what being an absolute chad is all about. You don't get a new phone, because money is a __little__ bit tight. But THEN...
The dreaded CAPITAL strikes, and requests of you to bend and fall onto your knees so as to provide intense, intimate and manual -- as well as oral -- PLEASURE to the [NOT SO] METAPHORICAL PENIS of the """SYSTEM""".
Oh, what an abominable, drooooooling revenant that lies before you!
"Gimme your ass... " he says, menacingly, as you wail about in a futile attempt to guard and preserve the very last vestiges of your own anal virginity.
And so you fight, and kick him in the NADS with everything you have, down to the final shreds of vigor. Victory! Or so you thought...
"You must... " he mutters, mortally wounded "update WhatsApp... "
"Still you breathe?!" you exclaim, suddenly transformed into a heroic, sexy moustachoed arquebusier "After I'm done ~OILING~ my VICTORIOUS CHEST, I *shall* bestow DEATH uppon you!".
But as you rip open your shirt to apply sensual oiling to your marvellous frontal assets, your nemesis reveals it's portentous Portugal: "this new version of Android... " he gasps as he perishes "is incompatible with your device... "
"Ughh! Sacrebleu!" you shriek out in pain, realizing that you are now unable to ACCESS THE FUCKING DATA THAT IS IN YOUR OWN FUCKING HARDWARE BECAUSE OF A STUPID FORCED BINARY INCOMPATIBILITY.
That's right. Now even if I *do* get a new phone, I can't do shit about losing all of the family memes. And contacts and all of that shit, but the stickers are more important. A minor inconvenience, yes, and it didn't need all of this preamble but I was doing the dramatic fight scene bit inside my head as I was writing and I got into it.
Because the only documented way to transfer all of that data is to OPEN THE APPLICATION and scan some code, but everytime I go to do that, IT TELLS ME I NEED TO UPDATE. And every time I GO TO UPDATE, it says that MY PHONE is TOO FUCKING OLD!! AAAAAAAGHGHGHGHGHGHGHG!!!!
And you too, might be a dashing french man from centuries past, with both balls and tits down to your fucking knees, folding your arms in a position that exhumes smugness in a disgustingly irreverent and self-aggrandizing way, looking at me as a mere plebeian who cannot wrap his head around the mystical art of interacting with Google's black deuce box.
And you would be somewhat right in your judgement! But just having to fiddle about with these fucking pocket Elmo screens is such a traumatic experience for me that I'd rather lose my stickers.
[ADBREAK] Are you a debonair victorian undercover butt pirate, taking unparalleled care of your Falstaffian, highfalutin poils pubiens? Need your "sword" sharpened, as you browse through the pages of this magnanimous lexicon? Would you rather allocate final death to your coworkers than learn one more synonym for sonorous, supercilious and pontifical?
We all know that ALL you need to help keep that honor intact is slaying your enemies in high-stakes combat. But how to satisfy less gallant needs, when male prostitution is outlawed in more than sixteen duchies?
Look no further than BloodCurse, the ancient hex that will haunt your family for countless generations! With BloodCurse, you may crawl the earth as a mindless, shameless, piece of shit cockswallowing JUGGERNAUT that craves nothing BUT the consumption of scabbed human ass!

rant/rant update
The same friend from my previous fb rant
https://devrant.com/rants/1338708/...
sends me this 😑
1 -
Dev: Sends weekly update email on Friday, as drudgingly required by management, outlining that stress level is high recently in the past two weeks and constant polling for feedback and updates is stressing him out, needs to slow down the pace
Management: (ON A FUCKING SATURDAY): "Received your email @fullStackChris"
WOW! THANKS FOR THAT INSIGHTFUL UPDATE! I BET YOU DID! I HAVE NO DOUBT GOOGLE'S SMTP SERVERS ARE RUNNING PROPERLY. AND AFTER READING IT, YOU HAVE THE AUDACITY TO @ ME IN A WHATSAPP MESSAGE. ON A FUCKING SATURDAY. I DON'T WANT TO HEAR FROM YOU, I DON'T WANT TO THINK ABOUT THE COMPANY OR ITS TASKS UNTIL MONDAY. PLEASE STOP.
I mean they must be fucking with me at this point, right guys? Maybe I should start writing stuff like "I need more tasks and more messages throughout the day" then I would probably receive less, I mean wtf is actually going on.7 -
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 -
Guyzz!! did u check the new WhatsApp update??
Similar to snapchat ....
no more permanent status's now😫6 -
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!?
It's gone.
Now iam thinking on the developer ,who pushed this update!
#FML9 -
i didn't want to leave home today, i still had a ton of code to deploy before a deadline.
i went out, phone gets stolen. and i end up spending a lot of money i am not supposed to spend.
thankfully, i had my WhatsApp logged in on my desktop PC and the latest update allows you to use the web version even when the device is offline, was able to reconnect with clients and assure them that i haven't disappeared with their money.
I feel numb, it's probably going to feel much worse when i wake up tomorrow, i just kept sleeping for the most of today which is kinda strange but i don't want to think much about it.1 -
I like the new WhatsApp!!
There I said it.
Why?
- 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 -
A single update broke my Asus RoG phone 5S.
WhatsApp has started to silently get voice calls out of nowhere.
New messages don't ring a notification sound anymore. Nor any updates on the lock screen/notification drawer.
WiFi doesn't connect automatically after turning it on. The list doesn't even show up. I have to turn my phone off and turn it back on after 5 mins to restore that functionality.
My phone automatically switches off at 18% battery. I've seen it happen 3 times by now.
Fuck modern software.
