This thread is for discussion about electronics and other related topics.

Literature to get you started in the hobby of electronics:
Getting Started in Electronics Forrest Mims III
The Art of Electronics by Paul Horowitz and Winfield Hill

Is reading literature not something you enjoy doing? You can learn about electronics by watching many of electronics YouTube channels instead:
eevblog
mikeselectricstuff
w2aew
Mr Calrson's Lab
Kerry Wong
Marco Reps

Pic related is my AVR dev board I've made last weekend, as I got tired breadboarding microcontroller every time I wanted to experiment with it. How's my layout and soldering? On the bottom of the board I've added +5v and GND header rails for easy access.

I was actually working on a simple irrigation system which is quite literally a relay hooked up to a 9 volt battery that will open or close a valve using GPIO pins but it turns out the water pressure was too much for the valve... I'll post pictures once I get a new one in the mail.

hell yeah! noice!

If you end up building a lot of this stuff, check out Kynar, also known as wire-wrapping wire, as an alternative to solid-core copper for the longer point-to-point connections on boards like that. It's a solid core 30AWG, so a smaller gauge, but very strong. I find it easier to work with, though it does need a little stripping tool (cheap) and a pair of needle-nosed pliers to take a little bit of insulation off the ends without mangling it.

Why do you have colored blobs in your captcha when you could remove them with CSS?

#captchaImage {
filter: url("data:image/svg+xml,<svg xmlns=%22http://www.w3.org/2000/svg%22 height=%220%22><filter id=%22rmblobs%22><feColorMatrix type=%22matrix%22 values=%221 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 1 0%22/></filter></svg>#rmblobs");
}

Honestly pretty neat. Had no idea CSS could do that.

I am typing this on a Macbook Pro right now.

I trust Apple more than Google and Microsoft, and I have been using their products for quite some time and have been pleasantly surprised each and every time. They make their product usage extremely straightforward and simple, and it saves me time whenever I need to accomplish tasks.

Acrobat Reader Alternative Anonymous 04/25/2017 (Tue) 08:35:05 [Preview] No. 8388 [Reply] [Last 50 Posts]
Are there any alternatives for browsing pdfs in browser that don't require Adobe Acrobat? The main problem is having to allow it each time in Firefox because it's apparently not secure.

You could technically open it in photoshop. Pdfs take forever to open no matter what you use.

It's for work and they come in from corporate, so for better or worse I'm not too concerned about potential security issues with them. I couldn't tell you the last time I used a pdf for anything on my personal BEAST!

Requirements for Secure Clock Synchronization Anonymous 10/20/2017 (Fri) 04:12:22 [Preview] No. 11578 [Reply] [Last 50 Posts]
https://arxiv.org/abs/1710.05798

This paper establishes a fundamental theory of secure clock synchronization. Accurate clock synchronization is the backbone of systems managing power distribution, financial transactions, telecommunication operations, database services, etc. Some clock synchronization (time transfer) systems, such as the Global Navigation Satellite Systems (GNSS), are based on one-way communication from a master to a slave clock. Others, such as the Network Transport Protocol (NTP), and the IEEE 1588 Precision Time Protocol (PTP), involve two-way communication between the master and slave. This paper shows that all one-way time transfer protocols are vulnerable to replay attacks that can potentially compromise timing information. A set of conditions for secure two-way clock synchronization is proposed and proved to be necessary and sufficient. It is shown that IEEE 1588 PTP, although a two-way synchronization protocol, is not compliant with these conditions, and is therefore insecure. Requirements for secure IEEE 1588 PTP are proposed, and a second example protocol is offered to illustrate the range of compliant systems.

Apparently I gave you too much credit when I assumed you had at least read the abstract. I guess you didn't even do that. Or couldn't, because of your poor English.

Once again, you're crying about something you're apparently incapable of understanding. You're fucking worthless.

All I know is I haven't touched my personal clocks in fifteen years to adjust for daylight saving time, or any other reason.

And I haven't worn a watch for even longer.

To this day I still run across systems and organizations that are helpless without a highly payed technician onsite to adjust for DST, actively babysit routine time-clock synchronizations, etc.

The underlying (in)security aspects are important too but—man oh man—people still can't embrace the basics.

Absolutely, imagine this progressive movement took complete control, a dystopian totalitarian maxist tranny future. A cyberpunk future where incorrect use of pronouns is prisonable and people break the law to share illegal opinions. It could be the 1984 of our time.

Sounds like the plot to Aerannis. It's some inventive stealth game, although 2D stealth games are getting so good lately I doubt it holds a candle.
