Software Engineering / These 15 unsung women in tech changed the world
« on: March 29, 2018, 08:54:13 PM »
The first programmers weren't men, and the first computers weren't machines. What they were, in both cases, were women.

Women's many contributions to technology are frequently left out of the history books. But lately, that's been changing — at least a little.

Ada Lovelace considered the first computer programmer and a visionary for what programming and computers could eventually become, has a technology award named after her, and a holiday devoted to celebrating her legacy. Katherine Johnson meanwhile, the NASA "computer" responsible for successfully plotting the flight paths of some of America's earliest space exploration expeditions, was the subject of the Hollywood blockbuster Hidden Figures (and the book it's based on).

1. The women who cracked the secrets of the universe with computation: Williamina Fleming and the Harvard "Computers"
2. The first computer programmers: The Women of ENIAC
3. The 'mother of computing': Grace Hopper
4. The woman you have to thank for hybrid car batteries: Annie Easley
5. The person who pioneered the gift that is 'WFH': Mary Allen Wilkes
6. Her work inspired Steve Jobs' creation of the first Apple computer: Adele Goldberg
7. The woman who basically invented online dating: Joan Ball
8. 'Google-ing' something would never have occurred to men without her: Karen Spärck Jones
9. Before there was GoDaddy, there was this woman: Elizabeth "Jake" Feinler
10. The person who made retro gaming awesome (before it was retro): Carol Shaw
11. Using Apple computers then and now was so intuitive because of her: Susan Kare
12. She paved the way for the smartphone market: Donna Dubinsky
13. She helped Obama save the internet: Megan Smith
14. The Marvel Cinematic Universe is awesome because of her: Victoria Alonso
15. Tech is more inclusive than ever thanks to her: Angelica Ross

It is just a sensor.

The winter of 2017-18 has recently become a throwback to the winters of yore — the ones your parents told you about. You know, back when they had to walk uphill both ways to school in the blinding snow and 0-degree temperatures?

Have you heard of cryptojacking? It's the practice of secretly using your computer's resources to mine cryptocurrency without the user's permission.

Typically, you'll see the practice on shady websites — popular Bittorrent site The Pirate Bay appears to have experimented with it at one point — but a cryptojacking program has recently been found in a popular Chrome extension.

Exactly nine years ago, on Jan. 3, 2009, the first block in Bitcoin's blockchain was mined.

Apple just confirmed that nearly all of its devices are impacted by the serious vulnerabilities affecting processors made by Intel and other chip makers.

In the company's first public statement on the vulnerabilities, Apple confirmed that all of its Mac and iOS devices are affected by the bugs known as Meltdown and Spectre.

"These issues apply to all modern processors and affect nearly all computing devices and operating systems. All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time," the company said.

Apple also explained that most exploits rely on apps with malicious code, reiterating that users should only download software from "trusted sources," such as its own App Stores. The company says it has addressed the bugs with its own software updates for MacOS (10.13.2), iOS (11.2), and tvOS (11.2).

For Safari, Apple says users can expect a software update meant "to help defend against Spectre," in the next few days. Google and Microsoft also previously issued patches meant to address the vulnerabilities, which first came to light earlier this week.

Software Engineering / CPU vulnerabilities, Meltdown and Spectre
« on: January 05, 2018, 09:51:28 PM »
By now you've probably heard. A large portion of the world's computer processors are vulnerable to at least one of two exploits that render them susceptible to hackers. But what, exactly, is going on — and what can you do to protect yourself?

While the answer to the first question is complicated, thankfully the answer to the second isn't. It turns out that companies like Google and Microsoft have been working behind the scenes to create patches for what the security community has named Meltdown and Spectre.

But we're not out of the woods yet, and, depending on your operating system, you still need to take some proactive measures to make sure your data is safe.

What's in a name: Meltdown and Spectre
One of the reasons this latest threat is so complicated is because it's actually multiple vulnerabilities that were unveiled at the same time. They're similar in some ways, but differ in important others — a fact hinted at by their names.

According to researchers, Meltdown "basically melts security boundaries which are normally enforced by the hardware." Spectre, meanwhile, "breaks the isolation between different applications" allowing "an attacker to trick error-free programs, which follow best practices, into leaking their secrets."

And what does that actually mean? Essentially, either of these vulnerabilities could be theoretically exploited to steal sensitive data, like passwords, off your computer. Spectre is also a threat to your smartphone, so no escape there. 
Furthermore, while Meltdown can be mostly mitigated with software patches, it is thought only certain exploitations of Spectre can be stopped in this manner. In other words, the latter is going to haunt us for some time and either could potentially require new processors for a complete fix (maybe).

So, who has patched?
Companies, if they haven't already, are rushing to release the aforementioned "mitigations" against possible attacks that could exploit Meltdown or Spectre (a helpful patch list can be found on the Computer Emergency Response Team site). Why mitigations? Well, because the patches and updates mitigate the risk — but might not remove it completely.   

Microsoft, on Jan. 3, released an update for devices running Windows 10 that was downloaded and installed automatically.

Google, for its part, issued a lengthy blog post on the same day detailing all the steps it had taken to protect users against both Spectre (Variant 1 and 2) and Meltdown (Variant 3). While a lot of that work happened behind the scenes, there are still some actions you need to take yourself. For example, you should definitely enable site isolation on Chrome.

Android devices with the most recent security updates are also protected from the above mentioned variants.

Apple was a little late to the customer-facing party, but on Jan. 4 made it clear that it is indeed paying attention. Specifically, the company said that — just like with its competitors — its products are at risk. That includes "all Mac systems and iOS devices," to be exact.

But wait, there's good news! Patches to help defend against Meltdown were released in iOS 11.2, macOS 10.13.2, and tvOS 11.2, and Spectre-focused patches for Safari should be hitting "in the coming days."

What do I need to do?
Meltdown and Spectre are the real deal, and rightly have security professionals concerned. However, at this time there are plenty of things you can do to protect yourself that don't involve buying a new computer.

Security researcher Matt Tait writes that, at least when it comes to Meltdown, typical computer users can mostly breathe easy. First and foremost, make sure your system is up to date. Download any all all patches for your operating system and browser of choice.

But, because more updates are coming down the pike, you're not done. Be on the lookout for any and all future security releases and make sure to install them immediately. Don't pull the classic "remind me later" bit.

And what about Spectre? This one is a little trickier.

"Spectre is harder to exploit than Meltdown, but it is also harder to mitigate," explain the researchers behind the discovery. "However, it is possible to prevent specific known exploits based on Spectre through software patches."

In other words, while nothing is perfect, much of the same advice applies as with Meltdown: update, update, update.

Which, well, has always been good advice.
