With the official letter in my hands, this concludes the long journey that started years ago. Thanks to all who supported me!
PS Well, there may be one more step, if my parents insist on the commencement ceremony.
Finally I figured out which curriculum applies – they have changed it 5 times since I’ve started my PhD. Lucky as I am, the classes and ECTS that I have collected so far can still be used today. Some bureaucratic hurdles later, the university online system now says that I have completed all my ECTS duties. Yay!
The road to my PhD is a bumpy one. But finally I think I am at the point where it becomes realistic for me to close this nasty open loop within the next 3 months.
The first step (that I am willing to blog about) was the informal submission of my thesis today. I submitted it both to my supervisor and the second, external examiner from the University of Ulm.
You have to watch this youtube video:
To me Fred Hersch’s version of “Both Sides Now” is profoundly beautiful and touching. It clearly stands out compared to the millions of stimuli that I get on a day to day basis. When I say stimuli I mean everything ranging from music, photography, writing, management presentations, engineering solutions, mathematical equations to coffee table discussions. In my quest to understanding “Life, the Universe & Everything” I can’t resist to ask: “Why?”.
To tell you the truth, I don’t think I have a way to test my answers (hypotheses) in a “true-or-false” manner. However my intuition at the moment tells me this:
For lack of scientific methods, I can’t be sure that this list is correct or exhaustive. But what I can say is that I find all of these qualities in Fred Hersch’s “Both Sides Now” and that I should certainly make sure they are in the random coffee table discussion to make it just as beautiful and touching.
Public-Key Cryptography is a truly magical thing and I often wonder why we don’t use it more often. We go on and complain about how it is too easy for government agencies to look into our digital lives, while we do have all the tools to prevent it. Only we don’t use them and we don’t seem to ask facebook, gmail and so on to use them – not that they would. The funny part is that it would not require a lot of effort, because computers could automatically do all of that stuff in the background. All that would be needed is that we were able to securely store one, long password (the private key).
In a nutshell public-key cryptography is a mathematical concept that allows us to encrypt a message that is intended to be read by just one person and to sign something to guarantee that it really came from you.
Let’s take a closer look: public-key cryptography is based on a pair of keys, lets call them #1 and #2. When one uses key #1 to encrypt a message one can only decrypt it again using key #2. The same is true for a message encrypted with key #2 – it can only be decrypted using key #1. In other words the two keys are kind of reversible operations that work in both directions. For instance
In addition to that it is important to know that it is (almost) impossible to find the keys from the Plain text and/or the Cypher Text.
Usually a person or entity (lets call this entity Alice) creates a pair of keys, where one is made public (the public key) and where the other key is kept secret. There are two typical use cases:
The secret key is Alice’s crown jewel that she must not lose or share with anyone, because anyone in possession of the secret key can do what Alice can do. Well that is why it’s called the secret key.
Again, all of this can stay in the background and as it can be done for you by software on your computer/phone/…, that has access to your locally stored secret key. If you are interested in implementing some of this stuff in your life, you might want to take a look at
Just by reading this article and by understanding it, you should have a pretty good idea about what level of protection encryption can give you and where potential problems may lie. Again, never forget: your secret key is your crown jewel that you must never share and that your software must never leak. By the way, this is something that is especially hard to check with closed source software and also something that the heartbleed bug may have caused.
I’ve started writing about it so I should finish it.
Where we left off: I had a job interview last week and I was expecting an offer in the next couple of weeks. Guess what: I received an offer today. And it did not come via a professional employer organization. No: Infineon made a valid, legit offer that truly is worth a thought.
In terms of money the offer is neither particularly good nor exceptionally bad.
Knowing what kind of salary to expect is one of the hardest things. Nobody in Austria really talks about their salary so you mostly rely on what friends tell you, internet research and what public research institutions pay (which has to be made public, because of transparency). Here are some examples of how I evaluated Infineon’s offer.
I have friends (also PhDs) working at Siemens VAI who earn about 5% more without the all-in option that Infineon has in all its contracts. The all-in option in Austrian contracts means that overtime will not be paid, as the salary is said to cover any overtime already. You would have to fight really hard to get rid of that option and accept a reduction in salary of about 15%. As 5% is not that much, it really comes down to the question of how much overtime you are expected to do. -> Neither good nor bad.
The post-doc position that my friend Reinhard has at university comes with exactly the same salary (according to the collective contract of the Austrian university system). My adviser also offered me a position as post doc, but I don’t think that the university landscape is for me. At any rate: -> Neither good nor bad.
Some information about what PhD graduates earned in Germany in 2012 can be found at http://www.ingenieurkarriere.de/_library/content/download/obj2407_Einstiegsgehaelter_fuer_Ingenieure_2012.pdf – Being just a little below what was the 50% mean tells me: -> Neither good nor bad.
It comes down to this: I will not sign that contract right away (as I would have if the offer were really outstanding) but I am also not going to turn it down. Starting in mid-March I will start looking for other options and when I have a range of offers, I will sit down to do my pros and cons list. The fact that I could put to use my knowledge in the probably most efficient way will be on the pros side and the salary will not be everything as long as it is above my personal limit of … well I am not going to share that number.
Actually I will not share any other information about my job search on this blog from now on. With HR being good at googleing these days, I guess it is safer that way. I am still glad I blogged about this first job application as it helped me bring order to my thoughts, realize what is important to me and define what my limits are.
In my last post I claimed that part of my research is paid for by Infineon, the rest of the money is actually coming from public funding. That is why we have to provide an annual report about our activities once a year. Today I spent most of my time preparing the 2013 report.
The afternoon mostly went into updating my CV and preparing job application material. This week’s discussions made me understand that I should at least be able to hand in something at any given time. – You gotta be prepared ;)
Ok, I’ll finally talk about my job. I am a PhD student and I am employed by the Johannes Kepler University Linz. However I am not involved in the teaching side of university apart from supervising Bachelor and Master Theses. I am a research assistant, I don’t TA and my research is (mostly) paid for by a company called Infineon.
To be a little bit more specific: I am doing research in the field of mm-wave radar systems. I’ve had quite a good time as PhD student. Lots of interesting conferences, research directions, research questions + great researchers around me. However (hopefully) I am going to graduate soon. Which brings me to the title of this post: I am going to be looking for a new job soon (May/June)!
I can’t help it, I have to make this yet another pleading for getting an engineering degree. One of the reasons: If you were flexible regarding the exact location, getting a job as an engineer has never been a problem during the last 20 years. To give you an example: As of today I haven’t applied for a single job, but I have received 6 job offers during the last year.
Today I was invited to yet another “job interview” at Infineon. – If you believe what some people say about a major Japanese customer awarding Infineon with a design win regarding automotive radar, you could image that they’d have a few of job openings in that field, such as
Actually it was less of an interview, because they know about my background. At any rate it was an interesting discussion and they are definitely on the list of addresses when I am going to start sending out job applications in April.
If you are a talented engineer, are looking for a job, would like to shape tomorrow’s driver-assistance system or maybe even self-driving transportation systems (aka cars), and are willing to move to a nice and dynamic city, I do highly recommend taking a look at the job offers above. Please apply even if you don’t think you’re the perfect fit!
Designing and building stuff that exploits physics to serve a specific function, that’s what I think it comes down when you ask me about what engineering is.
Today I took this screenshot that is almost like a stereotype for what we electrical engineers do. Actually this PCB (short for printed circuit board) was not even designed by me. It was designed by a gifted colleague who did it according to my specifications.
It’s the power supply for my newest 77-GHz radar front-end, which would be the really interesting part. Sadly I can’t show you the radar, because if I would I’d not be able to publish it in any scientific journal or conference. Something like this http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6507334 or http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6697594. And publications is what the scientific engineering community also lives for.
