Search - "layer 8"
We had a short power outage this morning. 30 min later I got an "urgent" call that someone's "computer" was not working in another branch of our company.
Not one person in that branch could figure this out so after them repeatedly messaging and calling me for around an hour I decided to come over.
I found out that the power wall plug to the monitor has a switch on it which this person accidentally kicked...
I fixed his problem in around 20 seconds. This same employee was one that somehow had his email account previously "hacked" and 8000 phishing emails were sent from his account in 1 hour.
I honestly think it is amazing people like this can even use a computer at all...6
Finally got my Bluetooth earphones!
It's called Pamu Scroll, funded in Indiegogo.
I bought it for $49 without shipping fee.
Now let me write a review about it here after using for about an hour or so.
Shipment from China is slow and hard to track unless it is classified as EMS, which mine wasn't, obviously.
It has some shock protection layer, but without that, nope! It was staying still inside the packaging though.
Beautiful. Just beautiful. Period. Just see the picture below.
It opens as a papyrus, maybe that's why it is called Pamu Scroll. Both the case's end, and earphones itself has magnets to hold each other.
It has a leather feeling to both the inside and outside of the case, and the touch control area of the earphones is also leather feeling, adding a nice touch that differs with other earphonnes.
The diamond feeling finish in the end of the case makes the case itself isn't earphones, more like some expensive jewelry case.
My ears are smaller than most people, for I am young, so it sometimes fall off when I jump, but when I put it the correct way, never falls out.
I am not an audiophile. I don't really care about the audio quality and how it sounds like unless the sound is too cringy and has so many white noise.
This earphones has white noise, but just a little bit, you won't notice except when you are in a quiet room.
The bass is boosted, but low sounds, and vocals can be cringy sometimes, so I should manually tune them with my phone's equalizer.
Not tested yet, but they advertise as using it in the shower.
7. Stereo call
Yup. Stereo call. Call in both ears. But only right microphone seems to get the voice.
Using BT 5, it is a breeze to connect.
Take both of them out, put to your ear, then ding! "Connected"
wireless charging for optional purchase - 10 bucks
You have 3.5 hrs of listening time in both ears, and you can charge 2 times more each by putting in the case.
Overall, it is awesome and let's just pray it doesn't break for at least for an year.
One side note, I can activate assistant by double tapping in the left ear (yes it is touch control), but my S8 asks me if I want to customize with Automate/Tasker. Yup!
Will share that later as well.
If you have any questions, ask me! Thanks for reading my first ever product review in devRant! <311
feature xyz doesn't work.
Spent hours trying to find the bug causing the malfunction, couldn't reproduce it on my devices.
Called to the customer to have a look on his device.
Feature xyz works as intended, the only bug: Too less patience at Layer 8.
Device just needs a little moment to establish a connection.
Patience is a virtue.
Wasted so much time because I used or instead of and in an if statement. Why am I so fucking stupid sometimes.
I've been wondering about renting a new VPS to get all my websites sorted out again. I am tired of shared hosting and I am able to manage it as I've been in the past.
With so many great people here, I was trying to put together some of the best practices and resources on how to handle the setup and configuration of a new machine, and I hope this post may help someone while trying to gather the best know-how in the comments. Don't be scared by the lengthy post, please.
The following tips are mainly from @Condor, @Noob, @Linuxxx and some other were gathered in the webz. Thanks for @Linux for recommending me Vultr VPS. I would appreciate further feedback from the community on how to improve this and/or change anything that may seem incorrect or should be done in better way.
1. Clean install CentOS 7 or Ubuntu (I am used to both, do you recommend more? Why?)
2. Install existing updates
3. Disable root login
4. Disable password for ssh
5. RSA key login with strong passwords/passphrases
6. Set correct locale and correct timezone (if different from default)
7. Close all ports
8. Disable and delete unneeded services
9. Install CSF
10. Install knockd (is it worth it at all? Isn't it security through obscurity?)
11. Install Fail2Ban (worth to install side by side with CSF? If not, why?)
12. Install ufw firewall (or keep with CSF/Fail2Ban? Why?)
13. Install rkhunter
14. Install anti-rootkit software (side by side with rkhunter?) (SELinux or AppArmor? Why?)
15. Enable Nginx/CSF rate limiting against SYN attacks
16. For a server to be public, is an IDS / IPS recommended? If so, which and why?
17. Log Injection Attacks in Application Layer - I should keep an eye on them. Is there any tool to help scanning?
If I want to have a server that serves multiple websites, would you add/change anything to the following?
18. Install Docker and manage separate instances with a Dockerfile powered base image with the following? Or should I keep all the servers in one main installation?
19. Install Nginx
20. Install PHP-FPM
21. Install PHP7
22. Install Memcached
23. Install MariaDB
24. Install phpMyAdmin (On specific port? Any recommendations here?)
I am sorry if this is somewhat lengthy, but I hope it may get better and be a good starting guide for a new server setup (eventually become a repo). Feel free to contribute in the comments.22
So I wonder if anybody on here has ever come across the LG G3 flickering screen issue.
I bought a LG G3 about 2 years ago. Fantastic phone.. Until all the issues started appearing.
First of all, the glass started lifting off on the left side of the phone, exposing the backlight layer, because the phone somehow managed to bend (insert iphone joke) inside my pocket. I was okay with it since it was a minor visual thing and didn't affect anything.
About 6 months ago the phone started lagging like crazy, and it kept getting worse and worse. It's so bad right now that Twitter will rarely fullscreen images, apps crash all the time, and occasionally the phone freezes to the point where it won't even react to the lock button.
About 2 weeks ago I started getting messages that my sim card was removed, and the phone starts rebooting itself. This would sometimes happen 10 times a day.
I was already pissed at all of these issues and in a desperate need of a new phone, but on Sunday a brand new issue appeared!
The phone's display randomly shut off, then wouldn't want to turn on, and occasionally turn on just to fade out or flicker away.
I of course went to google to see if anybody else has this issue... And it turns out that youtube is full of videos about it. Apparently the overheating issue these phones have slowly ruins the solder on the chips, which in turn creates a poor connection and causes these issues. The only way to solve it seems to be to reflow the chip, but others that tested that only got it to work for around 2 weeks before the issues started reappearing. I haven't tested it myself yet, but after disassembling, fucking around with it, and putting it all back together 3 times I sort of got it to work to the point where I can use it for several minuted before the displays fails. While writing this rant the display only quit on me once at the very beginning.
What I'm wondering is, why is it that nobody at LG decided to address the heating issue by perhaps throttling the CPU more? And I heard the G3 isn't the only LG phone with these issues?
This crap made me lose all my trust in the company. I wanted to upgrade to a G6 or V30, but because of this crap I think my next phone might be a Xiaomi.
This rant is now so long that it's barely even a rant or on topic. I think I should end it here since I have nothing more to say other than the LG G3 is a beautiful but crap phone, oh, and the new iPhone 8 is a flop9
8-layer tanh networks don't want to converge. Theory says it's fine, but they have to. The thesis chart will suck otherwise.
Has anybody experience with Scrum in small web development agencies? Especially estimating stories with story points instead of hours/days?
We have a new junior project manager, without any practical experience working agile, who wants to establish scrum because what he read about it sounded so good... I already worked agile with kanban before and I loved it, but I only have little experience with scrum.
I think scrum, or agile in general, won't work with the clients we have. Most of the time, our clients have a fixed deadline, a fixed budget (either money or time) and they know their requirements, so there is no much room for beeing agile.
Regarding story points, I just adding an unneccessary layer of abstraction, because the customer wants to know how long a specific feature takes. Sure, story points are just another, more dynamic unit for time, but then why nut estimate in static time unit in the first place? Another fear I have, is that some devs may be more ignorant regarding deadlines and expectations on customers side. "yeah I'm working for 10 days on this story, but it's 8 points!" instead of informing the project manager "Currently I spend 2 days on this feature, we estimated 3 days, but it seems I need 3 days more".
Maybe I shouldn't be worried, but it would be great if you could share your experience and learnings. Thanks in advance!14

Christ people. This is just sh*t.
The conflict I get is due to stupid new gcc header file crap. But what
makes me upset is that the crap is for completely bogus reasons.
This is the old code in net/ipv6/ip6_output.c:
mtu -= hlen + sizeof(struct frag_hdr);
and this is the new "improved" code that uses fancy stuff that wants
magical built-in compiler support and has silly wrapper functions for
when it doesn't exist:
if (overflow_usub(mtu, hlen + sizeof(struct frag_hdr), &mtu) ||
mtu <= 7)
and anybody who thinks that the above is
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it.
The code could *easily* have been done with just a single and
understandable conditional, and the compiler would actually have
generated better code, and the code would look better and more
understandable. Why is this not
if (mtu < hlen + sizeof(struct frag_hdr) + 8)
mtu -= hlen + sizeof(struct frag_hdr);
which is the same number of lines, doesn't use crazy helper functions
that nobody knows what they do, and is much more obvious what it
I guarantee that the second more obvious version is easier to read and
understand. Does anybody really want to dispute this?
Really. Give me *one* reason why it was written in that idiotic way
with two different conditionals, and a shiny new nonstandard function
that wants particular compiler support to generate even half-way sane
code, and even then generates worse code? A shiny function that we
have never ever needed anywhere else, and that is just
And yes, you still could have overflow issues if the whole "hlen +
xyz" expression overflows, but quite frankly, the "overflow_usub()"
code had that too. So if you worry about that, then you damn well
didn't do the right thing to begin with.
So I really see no reason for this kind of complete idiotic crap.
Tell me why. Because I'm not pulling this kind of completely insane
stuff that generates conflicts at rc7 time, and that seems to have
absolutely no reason for being anm idiotic unreadable mess.
The code seems *designed* to use that new "overflow_usub()" code. It
seems to be an excuse to use that function.
And it's a f*cking bad excuse for that braindamage.
I'm sorry, but we don't add idiotic new interfaces like this for
idiotic new code like that.
Yes, yes, if this had stayed inside the network layer I would never
have noticed. But since I *did* notice, I really don't want to pull
this. In fact, I want to make it clear to *everybody* that code like
this is completely unacceptable. Anybody who thinks that code like
this is "safe" and "secure" because it uses fancy overflow detection
functions is so far out to lunch that it's not even funny. All this
kind of crap does is to make the code a unreadable mess with code that
no sane person will ever really understand what it actually does.
Get rid of it. And I don't *ever* want to see that shit again.
