Twitter was atwitter yesterday with news of a big change to the site’s security protocols: users can now choose to enable two-factor authentication. That’s big news for everyone, even if you don’t use the social media site. After all, remember that fake tweet by a hacker that caused the stock market to briefly nosedive?

The new feature, which must be enabled by individual users, requires two steps to log in. You first enter your password (as always). Second, the system sends you a text message with a six-digit code that must be entered to get access to the account. It begs two very important questions: what about organizations and what about third-party tweeting apps?

With Memorial Day weekend coming up, it's time to think about treating yourself and your family to a much-needed vacation. It's difficult to leave a busy practice behind for some lawyers, but it is really important to de-stress once in a while. You will feel rested and refreshed when you return to the office in a couple weeks.

It used to be we would have to notify everyone of our absence and clear our schedule. Now, tech and vacations can work together. If you don't actually have to be somewhere, as the Lawyerist reminds us, technology can free us to get out of town and not look back. Well, not look back too much.

Here are five ways you can take a tech-sponsored vacation without your clients or opposing counsel making you regret it:

We've seen it again and again -- startups revolutionize a traditional practice only to meet resistance from outdated or misapplied laws. When Square introduced an iPhone attachment that processed credit card payments (genius), it ran afoul of state money transmitter laws. Uber allows you to hail a taxi from your phone (brilliant), but it clashed with state and city taxi laws across the country.

And now we have AirBnB. This ingenious startup allows you to sublet a spare room, or an apartment, for a few days at a time. For those visiting a pricy city, it's a godsend. In fact, Crain's New York notes that the startup is expected to generate nearly $1 billion in economic activity in New York City in 2013, most of which is outside the cluster of hotels in the midst of Manhattan.

The only problem is, the entire thing is illegal, at least in NYC.

FindLaw columnist Eric Sinrod writes regularly in this section on legal developments surrounding technology and the Internet.

Up until recently, and for years, I was a lawyer addicted to his BlackBerry. My BlackBerry always was on my hip, ready for immediate use. I became so proficient that I literally could type as fast with two thumbs on the device as I could with all of my fingers on my desktop keyboard at work. But other attorneys kept whispering in my ear, "Try the iPhone -- once you do, you will never go back to the BlackBerry."

So, over the New Year holiday, I tried my daughter's iPhone. I must say, I was most intrigued by Siri and the voice-recognition feature, not to mention the much larger screen.

Yesterday, we covered three suggested “pragmatic” gifts — the sort that will help advance your dear law graduate’s professional life. A laptop could help with cover letters and hopefully, paid legal work. Tablets are great for bar review apps (and bar review breaks!). Smartphones help her answer emails and take calls from potential employers.

They are all good gift ideas, but sometimes, fun trumps function. After all, your grad has been working hard for years to get her degree, and now little Jane will be taking a bar review course and searching desperately for an entry-level legal position. Maybe now is the time for something a little less pragmatic.

Little Jimmy is about to venture onward and conquer the world. You watched him cross that stage after three years in hell, three years of Socratic interrogation, three years of working towards an uncertain future in a profession suffering from unprecedented contraction.

But you don't want him to think about that last part. This is a time for happiness, optimism, and preparation for the next phase of his life (bar review!). You're probably considering graduation gifts. Instead of a traditional gift, such as a watch, how about a pragmatic gadget instead? These three tech toys will not only delight him with hours of Angry Birds, but also will help him study for the bar, send and receive job-related correspondence, and give him access to vast quantities of information from apps, the web, and the cloud.

As a faithful Nexus 4 and Nexus 7 (Google’s homebrewed Android phone and tablet, respectively) user, I am almost as enthusiastic about Android as that Droid Lawyer guy. So when I received an email from the ABA announcing the newly published Android Apps in One Hour for Lawyers by Daniel Siegel, my curiosity was piqued. A book that promises to introduce me to an already familiar world? Why not? Maybe I’ll learn something new.

Best of all? The ABA kindly provided a copy of the book for review, saving my $40 for more apps.

When we reviewed Total Attorneys way back in February, we walked away with a generally positive impression. Though the interface was less polished then its competitors, and though it lacked a couple of desired features, the bottom line was the bottom line: $1 per attorney.

That's $1 for calendaring, contact management, billing, invoices, trust accounting, and document storage. We figured the price was a lure to get users in, with hopes that they'd pay for upgrades, such as the $35/month for payment processing. Even if it was a lure, $1/user/month was an insanely low price.

The insanity just ended.

By now, many of you have heard of Prenda Law. The porn-trolling "law firm" spent years sending demand letters to (and filing boilerplate lawsuits against) those who illegally downloaded porn. Many of the letters contained shades of blackmail, with hints that their investigation of the matter would reveal that person's pornographic proclivities to neighbors and relatives if a settlement wasn't reached quickly.

The legal basis of the scheme was simple: The lawyers acquired the copyrights to pornographic films and assigned the rights to a number of newly-formed shell companies, such as Ingenuity 13. Prenda Law would then monitor BitTorrent for IP addresses and file subpoenas to obtain the identities behind the IPs.

The lawyers would then send the blackmail letters, offering to settle for about $4,000. They'd also file boilerplate lawsuits in bulk, hoping for default judgments. If anyone lawyered up and fought the case, they'd drop it and move on to the next porn pirate.

Though lawyers are becoming increasingly mobile, we can’t do everything on a tablet or cell phone. Truth be told, there’s nothing quite like the ol’ QWERTY keyboard and 100 wpm typing to burn through a brief or blog post in a hurry.

It’ll be awhile before we reach the “post-PC” age. You likely still do most of your lawyering on your computer, and it you are nearing your upgrade time, you might be perusing your options.

Wait.
