If you are taking advanced operating systems course at Georgia Tech (OMSCS) and want to run the the lab environment on your mac laptop (or desktop) using Virtualbox, then follow the below instructions. Below, you’ll find a Vagrantfile that will launch a virtual machine, install Ubuntu and configure nested virtualization:
After reading Daniel Wessel’s post1 on creating a virtual library, I’ve decided take the leap and convert the majority of my books — classic literature will remain sitting on my book shelf — into digital form. To accomplish this, I invested in a Fujitsu ScanScan IX500. The scanner runs for about $400.00. I selected this model based off of the many reviews2 touting that this scanner scans fast (duplex scan takes about 1 second for front and back), produces high-quality documents, and provides an easy to use intuitive touch screen interface. And after receiving and unpacking the equipment last night, I agree wholeheartedly.
I’m pretty embarrassed of how disorganized and messy our house looks and feels. I forget the color of the bathroom tile since its hidden from view due to dirty clothes sprawled out across the entire floor. I’m afraid of raising my standing desk for fear of a monitor toppling over due a caught wire and afraid of one of the many mugs spilling four day old tea. I cannot wipe down the kitchen counter because of the mega sized Maggi Soy Sauce (super delicious, by the way) towering over the stacked, dirty (or maybe clean) plates. By living this way, we’re sort of disrespecting our house, not taking care of it and looking after it in the way we should.
It’s time for a change.
Today I practiced my guitar for 20 minutes, a generous amount of time these days (if you are parent you’ll understand). During this practice session, I worked ear training: I looped the song The Funeral (Band of Horses) on my iPhone and played along, plucking the individuals notes in chord progression on my Traveler’s acoustic guitar.
During the practice session, I was able to nail down all the notes from the first two chords (triads) and was also able to determine that song was written in the key of G# (thanks music theory). However, I am a bit confused because the 2 of a major key, normally a minor chord, was played as a major. Is this swap of minor and major chord an example of modal mixture?
Ultimately, I was unable to play the entire chord progression by ear and ended up finding a guitar tutorial1; uploaded on YouTube. Despite that, I’m happy with the progress I’ve made over the last two years of working on my music craftsmanship.
Have you ever read a passage that flows (i.e. has cohesion) but it just … doesn’t make any sense, no matter how many times you read it? You can lexically parse the passage (i.e. makes grammatically sense) but you cannot grasp the meaning? If so, the passage probably lacks coherence.
According to Joseph Williams2, author of Style – Ten Lessons in Clarity & Grace, a passage is coherent when the sentences merge into a unified passage. The passage’s author not only needs to link pairs of individual sentences, but they need to sequence the sentences so that together, the sentences are unified. To this end, Joseph Williams suggests focusing the topics to a limited number of concepts. By doing so, the author helps prevent scattering the reader’s sense of what a passage is globally about. Moreover, Joseph Williams suggests using “connectives”, helper words that link one sentence to the next, words such as: and, but, or, therefore, nonetheless, however, even though, despite.
But it’s … not that simple. Should connectives always be sued? According to Steven Pinker1, using too many connectives will belabor the obvious and potentially water down the material, patronizing the reader. On the other side of the spectrum, using an insufficient number of connectives can leave the reader puzzled and confused as to how one statement follows from the last.
Wanting to better understand how to achieve a coherence, I read the chapter “Coherence” in Steven Pinker’s book. In the section that follows, I’ll share the 13 of the different ways one sentence can flow to another. These different methods are also known as coherence relations.
If you are looking for a quick, delicious, healthy (no oil), plant based meal that takes only 30 minutes (15 of those minutes are waiting for the dish to cook in an instant pot) to whip up, look no further. Check out Jill McKeever’s video on “The Red Lentil Stew From Instant Pot”:
I’ve taken her recipe and slightly modified it, changing the proportions of the ingredients. More specifically, I kick up the number of potatoes. In the video, you’ll see she tosses only in 1 potatoes or so; I like my dish a little more starchy and tend to chop up and throw in in twice the amount (about 4 or 5 potatoes). And occasionally, I’ll mix it up with a zucchini (or as my British wife calls it: “Courgettes”).
So the modified recipe is as follows:
Definitely try this out. It’s so easy and so delicious! Bon Appetit!
Many people (including myself) fear that we will be perceived as a fool if we publish on a post blog that contains a mistake, a public mistake. Nobody wants to be humiliated publicly. This fear is encapsulated inside of a quote that Sacha shares:
“Better to remain silent and be thought a fool than to speak and remove all doubt.”
But like Sacha, I’d rather know when I’m being a fool. At work, I never shy away from asking “dumb questions”. I’ve come to realize that there’s normally at least one other person who has the same question but they often shy away from asking it for fear of looking stupid. I’ve been that person and I later kick myself in my butt for not speaking up.
If you don’t put your thoughts into words — verbally or written — then its very easy to convince yourself that you understand something, when you really don’t. So many times in both my career and personal life I thought I understood some topic but when I started forming those thoughts into my own words, I realized I had gaping holes in my understanding. For example, my co-worker asked how and why we prefetch in our code base, and when I started explaining, I realized I had to refresh my memory on the cost of certain instructions and CPU pipelining.
In summary, do yourself a favor and when you are learning something, try and explain it someone. You might discover gaps in your understand. And that’s perfectly okay because your writing becomes a “history of change and learning”. This allows us to take a step back and honor our progress and allow us to remember our mistakes and lessons learned along the way.
