Reproducible builds
Whilst anyone can inspect the source code of free software for malicious flaws, most Linux distributions provide binary (or "compiled") packages to end users.
The motivation behind "reproducible" builds is to allow verification that no flaws have been introduced during this compilation process by promising identical binary packages are always generated from a given source. This prevents against the installation of backdoor-introducing malware on developers' machines - an attacker would need to simultaneously infect or blackmail all developers attempting to reproduce the build.
This talk will focus heavily on how exactly software can fail to be reproducible, the tools, tests and specifications we have written to fix and diagnose issues, as well as the many amusing "fails" in upstream's code that have been unearthed by this process. In addition, you will learn what to avoid in your own software as well as the future efforts in the Reproducible Builds arena.

Ryobix is a loyal warrior and guard to his master, Valior. Being mostly robotic, the only living tissue is overgrown. Thus creating spikes and his hunched, slender shape. He runs the main AI controlling system for the TRS models. Mostly to keep the system updated, clean, and virus/Trojan/malware free. Ryobix uses his holographic screens and pre-recordings to speak; even though he can speak himself. Ryobix himself is a very advanced robotic system, years ahead of our technology today. Skilled in the ways of defense and doesn't ever flinch.

Example of Android malware that asks permission to sent SMS messages to numbers cybercriminals can profit from.
Headline news states that in the UK many businesses and NHS Trusts ave been victims of a computer encryption virus - here is how it may have happened. An incoming eMail to an employee refers to an unpaid invoice, the employee clicks on a link to an external website (eg. Sharepoint) where the criminal hackers have been allowed to host their encryption ransomware / malware.

Quoting from the placard:
The Morris Internet Worm source code
This disk contains the complete source code of the Morris Internet worm program. This tiny, 99-line program brought large pieces of the Internet to a standstill on November 2nd, 1988.
The worm was the first of many intrusive programs that use the Internet to spread.
-- The Computer History Museum
Quoting from Wikipedia | Morris Worm:
The Morris worm or Internet worm of November 2, 1988 was one of the first computer worms distributed via the Internet. It is considered the first worm and was certainly the first to gain significant mainstream media attention. It also resulted in the first conviction in the US under the 1986 Computer Fraud and Abuse Act. It was written by a student at Cornell University, Robert Tappan Morris, and launched on November 2, 1988 from MIT.
It's somehow less impressive to just have a copy of a program on exhibit like this.
I mean, for starters does this floppy even work anymore, or has it demagnetized over time? Is there a backup somewhere, and if so, does it work?
Questions like this is why people hate making museum exhibits for computer nerds.

The taste of shame is what Kenzero loves the most. The Kenzero Twins work together, one half investigating, uncovering every deepest secret of their victim, just so the other half can reveal everything as loud as it can, to everyone. If you have something to hide, it's already too late: everybody will know what you've done.

Example of Locky ransomware.
Locky is ransomware malware released in 2016. It is delivered by email and after infection will encrypt all files that match particular extensions.
After encryption, a message (displayed on the user's desktop) instructs them to download the Tor browser and visit a specific criminal-operated Web site for further information.
The current version, released in December 2016, utilizes the .osiris extension for encrypted files.
Many different distribution methods for Locky have been used since the ransomware was released. These distribution methods include Word and Excel attachments with malicious macros,DOCM attachments and zipped JS Attachments.

I'VE BEEN SCAMMED!!! My son informed me that the whole computer VIRUS thing that I mentioned the other day was a SCAM! My Bank said the first step is to phone the company and cancel the 5-year Protection I paid for and to ask for a refund, which I have just done. Doubt that will happen. Also have to now take my computer in to be cleaned of all the malware, etc. they have installed on my hard drive. What a PAIN! I'm always very careful of scams, but I sure fell for this one.

Our weather forecast for this morning gives a temperature of -2C (windchill -4C). We are under a Freezing Drizzle Advisory, too. Whatever happened to sunshine and warmth? Recently, we have been having rainy, dreary (and the day before yesterday, very foggy!) weather. A decision needed to be made - to go or not go on a birding day trip east of the city. Usually, people don't have to register for most outings, but the trip on 20 September 2018 was different, thanks to a change in how outings will be run in the future. I had registered, which helped push me out of the door on a day with a forecast for rain all day. So glad I did go, though, as once the dense fog eventually pretty much lifted half way through the day, the sun came out and it was beautiful.
Our route took us to places such as (very foggy) Weed Lake and, much further east, Marsland Basin. I love our trips in this direction from the city, even more so because I very rarely do the drive myself.
As for birds, 56 species were spotted, most at extremely far distances. As usually happens, I only saw some of them, but was happy with the ones I did see. Not much chance to take photos of birds, but as usual, my camera lens turned to everything else around me - scenery, wildflowers, insects, old barns and sheds, and a few beautifully delicate spider webs covered in dew, rain or fog drops. I loved finding these! I wish I knew what kind of spiders create the much more random webs - different from the full-circle ones I normally come across. I can only imagine what these webs might have looked like in sunshine, instead of heavy fog. Still, I'm happy that a few photos are fit to post, to remind me of nature's beauty this day.
After our first stop, we decided to have an early coffee break, in hopes that the fog would improve. Eventually, it did, slightly. Fog is definitely not what one wants on a birding trip! I think we had seven stops in total, including one at Marsland Basin, our most distant destination. Such a great place to visit and enjoy. While everyone else was peering through their binoculars at the distant wetland, I was wandering through the trees and grounds surrounding Lynn and Sue's home, catching a Sunflower shot here and a donkey shot there, and so on. One of my favourite places. Sorry we missed you, Lynn!
Many thanks as always, Andrew, for yet another very enjoyable trip. Thanks, too, for everyone combining to create the list of total species. So many great pairs of eyes. It felt so good to be away from my computer for hours, too, especially after getting a Virus the previous day and coming very close to losing everything on my computer!
