The most common mistake people do is trying to learn some complex cutting-edge technology from scratch. Cutting-edge technology is just combining old technology in new ways to solve new problems. To learn it, first learn existing technology. Existing technology is here to stay, it's well-explained, and it's usually much simpler to understand. Then the rest will just click.7

Question for leads...
Have you found that it's possible to have a balanced leadership style instead of ruling with an iron fist?
Let me explain what I mean.
There's always going to be room for improvement, there's going to be at least the occasional issue that happens, etc.
As a lead, your job is to not have issues happen and to have the team work effectively.
Now, for me, my goal was to have a balanced style in the sense that if there's a small issue or small room for improvement, but the team is already stressed, I take the heat for it if necessary and let them relax so they're not stressed and they can focus on the bigger things.
For medium improvements, I essentially put it to the vote so the team can have their say in whether they agree with the proposal on improvement.
And so on, idea being to have a balance between "Do what I tell you" and "do whatever you want".
However, I have found that doing so does essentially nothing to improve team morale and team cohesion. Any thing that needs doing and I force them into it, any thing I don't protect them from, any thing they don't agree with will still manifest as problems in the team, a single "you have to do this" will make them complain about the leadership style being "force to implement".
Being completely hands off and essentially not a lead, just basically a support dev more or less, is not what I'm really looking for, but also isn't good for a team that does genuinely have things that need to improve (stupid errors not being caught in dev OR review, system not being fully testable because of external dependencies that are not really necessary for tests, etc).
So the only option I see there is simply ruling with an iron fist and leaning into being that hated lead that just forcea you to do things and "doesn't care about you".
I've already stepped down from this lead position because I don't want to be that guy, but if I'm looking for another position I'm curious if this is just universal or hae you guys found that it IS possible to have a "good team" where you can be adults and discuss things as a team and improve as a team?6 -
Hello everyone.
So, i am thinking about where to get lists of programming languages, frameworks and softwares that is fundamental. For example:
If i would like to develop a web site. I would use html, css, js & php. Maybe a site or frameworks for reference and 'roadmap'. I want to become a good programmer.6 -
I absolutely love the email protocols.
IMAP:
x1 LOGIN user@domain password
x2 LIST "" "*"
x3 SELECT Inbox
x4 LOGOUT
Because a state machine is clearly too hard to implement in server software, clients must instead do the state machine thing and therefore it must be in the IMAP protocol.
SMTP:
I should be careful with this one since there's already more than enough spam on the interwebs, and it's a good thing that the "developers" of these email bombers don't know jack shit about the protocol. But suffice it to say that much like on a real letter, you have an envelope and a letter inside. You know these envelopes with a transparent window so you can print the address information on the letter? Or the "regular" envelopes where you write it on the envelope itself?
Yeah not with SMTP. Both your envelope and your letter have them, and they can be different. That's why you can have an email in your inbox that seemingly came from yourself. The mail server only checks for the envelope headers, and as long as everything checks out domain-wise and such, it will be accepted. Then the mail client checks the headers in the letter itself, the data field as far as the mail server is concerned (and it doesn't look at it). Can be something else, can be nothing at all. Emails can even be sent in the future or the past.
Postfix' main.cf:
You have this property "mynetworks" in /etc/postfix/main.cf where you'd imagine you put your own networks in, right? I dunno, to let Postfix discover what your networks are.. like it says on the tin? Haha, nope. This is a property that defines which networks are allowed no authentication at all to the mail server, and that is exactly what makes an open relay an open relay. If any one of the addresses in your networks (such as a gateway, every network has one) is also where your SMTP traffic flows into the mail server from, congrats the whole internet can now send through your mail server without authentication. And all because it was part of "your networks".
Yeah when it comes to naming things, the protocol designers sure have room for improvement... And fuck email.
Oh, bonus one - STARTTLS:
So SMTP has this thing called STARTTLS where you can.. unlike mynetworks, actually starts a TLS connection like it says on the tin. The problem is that almost every mail server uses self-signed certificates so they're basically meaningless. You don't have a chain of trust. Also not everyone supports it *cough* government *cough*, so if you want to send email to those servers, your TLS policy must be opportunistic, not enforced. And as an icing on the cake, if anything is wrong with the TLS connection (such as an MITM attack), the protocol will actively downgrade to plain. I dunno.. isn't that exactly what the MITM attacker wants? Yeah, great design right there. Are the designers of the email protocols fucking retarded?9 -

In today's episode of "Am I paranoid already?" - Caching Bind resolver forwarding queries to a DoH client connecting to Cloudflare
A fun little thing to configure, and now, anytime I am on my VPN, all my DNS traffic should be completely untrackable.
Does that make me paranoid? Maybe a little... But, the knowledge that noone - not even my ISP, can see what I am doing on the internet, is kinda... Heartarming.
Now, all that's left, is for eSNI to roll out and get implemented by all major web browsers, and most snooping will be completely done for...4 -

I'm 54 y.o.
I think I'm completely outdated in my skill, as in the last 14 years, I worked on a specific business problem, with an old technology: a JSP application + javascript + postgres.
I do understand software development, agile, web application development, linux server, basic/moderate AWS skills, etc.
Now they laid me off instead of including me in the evolution of version 2 of the software. Maybe covid, company had almost no cash-flow. Well they have now...So basically they fired me to find money to rewrite the application.
I feel without hope at my age.
I'm a generalist.
I can understand fairly well everything you'll throw at me, reactnative, angular, nosql, python, but I have little first-hand experience.
I don't have a lot of management skills, even if I've given frequent presentations to C-roles and board, and I implemented a whole agile methodology in my team.
I don't know what to do.
The amount of technology to study is huge nowadays. When I was younger I could get away with some php and java.
Full-stack developer is a big word for me. Maybe I could handle a full stack web application, but not from scratch.
I feel at my age, I'll compete with 20-something guys with better skills and lower salary requests.
I don't think I can pull a night anymore.
I'm trying to shoot high to management positions with no much success.
I'd like to go on developing, I know that there are 50-something developer out there, but who managed to find a new position at 55? at 60?
As soon as I finish the few money I spared, I'll be on the street, I'l be the "website for food" guy.49 -
The last Windows 10 update (10 days ago) has fucked up my dual boot with Elementary OS (Linux distro). I tried many things to retrieve it but with no success !
So I reinstalled it ! So now I would like to know how to prevent this shit happened again. Is there a way to do that ? Maybe a /boot partition or it's unnecessary ?7 -

*In a team meeting*
Me: *happily jotting down notes in markdown*
Other guy: "Dude what are you doing? Pay attention."
Me: "Umm... I'm taking notes?"
Other guy: "But why does your MS Word have black background?"
Me (a bit lost): "Umm... That's not Word. That's my text editor."
Other guy: "Alright... But how do you convert your notes into Word then?"
Me: "... I don't."
Other guy: *stares at me*
Me: * stare back*
It was a nice conversation.12 -
Just wrote a (PHP based) proxy which can cache resources being requested and serve them to clients.
The idea is that (I'm going to write a firefox add-on for it too, yes) you can install the add-on and any resource (js/CSS, general web resources which would be downloaded off of googleapi's etc) hosted with Google would be proxied through the server running the proxy, meaning that one wouldn't have to connect to the mass surveillance networks directly anymore as for static resources.
I think checksum verify stuff would still work as the proxy is literally a proxy, the content will be identical to the 'real' resource. (Not sure about this one, enlighten me if this isn't true)
Input appreciated!17 -

I'm a back-end developer trying to improve my front-end skills, is there any good website that I can replicate/remake so I can improve my skills?3

Things have been a little too quiet on my side here, so its time for an exciting new series:
practiseSafeHex's new life as a manager.
Episode 1: Dealing with the new backend team
It's great to be back folks. Since our last series where we delved into the mind numbing idiocy of former colleagues, a lot has changed. I've moved to a new company and taken a step up as a Dev manager / Tech lead. Now I know what you are all thinking, sounds more dull and boring right? Well it wouldn't be a practiseSafeHex series if we weren't ...
<audience-shouting>
DEALING! ... WITH! ... IDIOTS!
</audience-shouting>
Bingo! so lets jump right in and kick us off with a good one.
So for the past few months i've been on an on-boarding / fact finding / figuring out this shit-storm, mission to understand more about what it is i'm suppose to do and how to do it. Last week, as part of this, I had the esteemed pleasure of meeting face to face with the remote backend team i've been working with. Lets rattle off a few facts to catch us all up:
- 8 hour time difference to me
- No documentation other than a non-maintained swagger doc
- Swagger is reporting errors and several of the input models are just `Type: String`
- The one model that seems accurate, has every property listed as optional, including what must be the primary key
- Properties go missing and get removed at the drop of a hat and we are never told.
- First email I sent them took 27 days to reply, my response to that hasn't been answered so far 31 days later (new record! way to go team, I knew we could do it!!!)
- I deal directly with 2 of them, the manager and the tech lead. Based on how things have gone so far, i've nick named them:
1) Ass
2) Hole
So lets look at some example of their work:
- I was trying to test the new backend, I saw no data in QA. They said it wouldn't show up until mid day their time, which is middle of the night for us. I said we need data in our timezone and I was told: a) "You don't understand how big this system is" (which is their new catch phrase) b) "Your timezone is not my concern"
- The whole org started testing 2 days later. The next day a member from each team was on a call and I was asked to give an update of how the testing was going on the mobile side. I said I was completely blocked because I can't get test data. Backend were asked to respond. They acknowledged they were aware, but that mobile don't understand how big the system is, and that the mobile team need to come up with ideas for the backend team, as to how mobile can test it. I said we can't do anything without test data, they said ... can you guess what? ... correct "you don't understand how big the system is"
- We eventually got something going and I noticed that only 1 of the 5 API changes due on their side was done. Opened tickets. 2 days later asked them for progress and was told that "new findings" always go to the bottom of the backlog, and they are busy with other things. I said these were suppose to be done days ago. They said you can't give us 2 days notice and expect everything done. I said the original ticket was opened a month a go *sends link* ......... *long silence* ...... "ok, but you don't understand how big the system is, this is a lot of work"
- We were on a call. Product was asking the backend manager (aka "Ass") a question about a slight upgrade to the new feature. While trying to talk, the tech lead (aka "Hole") kept cutting everyone off by saying loudly "but thats not in scope". The question was "is this possible in the future" and "how long would it take", coming from management and product development. Hole just kept saying "its not in scope", until he was told to be quiet by several people.
- An API was sending down JSON with a string containing a message for the user with 2 bits of data inside it. We asked for one of those pieces to also come down as a property as the string can change and we needed it client side. We got that. A few days later we found an edge case and asked for the second piece of data to be a property too. Now keep in mind, they clearly already have access to them in order to make the string. We were told "If you keep requesting changes like this, you are going to delay the release of the backend by up to 2 weeks"
Yes folks, there you have it, the most minuscule JSON modifications, can delay your release by up to 2 weeks ........ maybe I should just tell product, that they don't understand how big the app is, and claim we can't build it on our side? Seems to work for them
Thats all the time we have for today,
Tune in for more, where we'll be looking into such topics as:
- If god himself was an iOS developer ... not
- Why automate when you can spend all day doing it by hand
- Its more time-efficient to just give everything a story point of 5
- Why waste time replying to emails ... when you can do nothing instead
See you all next week,
