What happens if someone crops and scrubs the metadata of the original image and then shares it? Can mediachain identify the original source of the new image?


Any metadata that is stored in EXIF or part of the file can be easily stripped out. This is why Mediachain uses perceptual recognition technology similar to Shazam or Google Image search to identify media based on how it looks or sounds, automatically resolving to metadata stored in Mediachain. Near duplicate image detection is quite far along and works very well even for images that are cropped, distorted, etc.

More on our approach in this post: https://blog.mediachain.io/perceptual-resolution-9c00ad5ca55...

                    ~~~ The Palace ~~~
                 by Rudyard Kipling, 1902

  When I was a King and a Mason -- a Master proven and skilled --
  I cleared me ground for a Palace such as a King should build.
  I decreed and dug down to my levels. Presently, under the silt,
  I came on the wreck of a Palace such as a King had built.

  There was no worth in the fashion -- there was no wit in the plan --
  Hither and thither, aimless, the ruined footings ran --
  Masonry, brute, mishandled, but carven on every stone:
  "After me cometh a Builder. Tell him, I too have known."

  Swift to my use in my trenches, where my well-planned ground-works grew,
  I tumbled his quoins and his ashlars, and cut and reset them anew.
  Lime I milled of his marbles; burned it, slacked it, and spread;
  Taking and leaving at pleasure the gifts of the humble dead.

  Yet I despised not nor gloried; yet, as we wrenched them apart,
  I read in the razed foundations the heart of that builder's heart.
  As he had risen and pleaded, so did I understand
  The form of the dream he had followed in the face of the thing he had planned.

  When I was a King and a Mason -- in the open noon of my pride,
  They sent me a Word from the Darkness. They whispered and called me aside.
  They said -- "The end is forbidden." They said -- "Thy use is fulfilled.
  "Thy Palace shall stand as that other's -- the spoil of a King who shall build."

  I called my men from my trenches, my quarries, my wharves, and my sheers.
  All I had wrought I abandoned to the faith of the faithless years.
  Only I cut on the timber -- only I carved on the stone:
  "After me cometh a Builder. Tell him, I too have known!"

No, there was no time limit


omg, you're right.


Kind of sneaky to put important details in parentheses like they did. I would have let that omission slide, especially considering the typical candidate we get.


my thoughts exactly


Yep, all the source code is in the page.

The hard part is parsing your gmail.mbox file from google takeout. You can use `egrep '^From [0-9]|X-Gmail-Labels' gmail.mbox` as a good starting place for finding the labels and dates for each email. Personally, once I had the data I stored that data in a SQL database and ran an aggregate query to count the emails for each label every month.

I'm sure there is a better way to do it.

Solid advice from the comment section in the article: "Major in business? Just read Business Week and the Economist every week and you'll pick up more than you will in a business program. Major in something worthwhile."


An undergraduate degree in business isn't that useful by itself. An engineering degree will buy you a lot more credibility down the line, no matter what you end up doing. But the real money isn't in being an engineer--it's in finance, operations, and strategic management. So the MBA is still crucial--it allows you to transition between the two domains.


Do you really think an MBA is that important for operations?

I sometimes think it would be fun to get one (although, since I dropped out of MBA undergrad, the only easy way for me to get one is LSE or LBS or another UK or EU school).

I know finance to the extent of "how to read a balance sheet", run a startup, or do very basic investment analysis, but nothing really exciting. If an MBA actually would be useful for something beyond credentialing in operations/management, I might consider it more.


I have a business degree and an MBA and I agree with this statement. If I could go back, I would major is something more technical.

But, I also have an MBA. And I would get that again.


> I have a business degree and an MBA and I agree with this statement. If I could go back, I would major is something more technical.

I don't know much about MBA programs, but don't you study Economics, Accounting, Finance...? Or Economics isn't considered technical enough?


I wouldn't consider economics to be technical at all. Traditional Economics is the art of taking outdated physical models as analogies for sociological phenomena. There are modern branches of economics that are useful and arguably even technical, but I doubt you get into them as a typical undergraduate.


In my opinion you don’t get a lot of hard skills at a MBA program. MBA program usually gets you 1-2 courses on any specific topic. If you get a Harvard MBA, you'll get two Finance and one Accounting course, and part of one course will cover econ. Just look at the curriculum http://www.hbs.edu/mba/academic-experience/curriculum/Pages/...

I had the choice of getting an MBA or MS in Finance. I went for the MS Finance and took these courses; 2 stats, 2 econ, 2accounting, 2 Managerial Analysis, and 8 Finance courses as my paid for course load. I took non-required courses in Operations management, MIS, Leadership, Business Law, and Marketing at the cheap Grad student rate and sat in the same classes as MBA’s.

Go to my schools website and you can see the simple thought approach difference between an MS and MBA The MBA program landing page is all about school rank, how to get in, cost. The course work isn’t directly linked to that page. http://bauer.uh.edu/graduate-studies/mba/index.php The M.S. Finance page tells you the goals about what they want you to learn, and has the curriculum http://bauer.uh.edu/graduate-studies/ms-finance/index.php MBA programs are LARGELY about getting credentials. They are profit centers for universities, and get run that way. Most students are there to punch a card. You can see that mindset in terms of how the websites are set up.


I don't have a problem with MBA course flaunting their rankings, but why sacrifice learning? You can very well flaunt your ranking, and teach statistics and economics.
