So, last week we updated the Anxiety Machine - aka the experimental LLM we are running at the university and that I am bullying from time to time.

The good news? The Anxiety Machine is up to near 100% now in getting papers that have been published in English up until Q3 of 2024 right, and can in most cases even produce the DOI. That is really, fucking good. I really cannot emphasize how good that is. This is a massive help in research. I really cannot emphasize this enough. Being able to sit there and go: "Hey, I have been wondering about this and that, are there papers on that?" And it gives you both papers and possible keywords to search for? Yeah, fuck. That is great.

We also found one way to make the anxiety machine indeed suffer its anxiety attacks almost certainly: letting it guess and only giving it one chance to guess right. It is fine as soon as you tell it "three chances". It will do okay with that. But as soon as it only has one guess? Yeah, that machine is going to go down a circular thing of "AAAAAAAAAAAH! I HAVE TO GET IT RIGHT! I AM SO INTELLIGENT!!!!" I crashed several instances of it by trying to push it to make a single guess.

Something that is also a bit frustrating with it is, that we have one training package that we just purchased - and that very very clearly includes pretty much all the content from the fandom.com wikis, Ao3, and Reddit. Right now we have in that machine (that is running locally on the university's servers) 4 data sets: The first is just creative commons and public domain stuff that is offered by Google I think, the second is one that was purchased by the uni in November last year (and clearly involves a lot of data crawled content), the third is one academic set that has been put out by Stanford I think, and the last one is one that the research team at the uni created for themselves.

Information Arena has no doubt revolutionized the explicit world. This 21st skin innovation has indeed redefined and reshaped the rule of business engagements in such wise well as continually routine of a weak existing.Opening upset upon global recession and rising unemployment, IT jobs are always poisonous in charging.<\p>

New innovation and technologies are bursting out all-present.Some of the experts predict THEY to subsist the most booming portion way the coming years, in such wise the wish of privity academic discipline can never remain repleted. IT has changed the will people communicate and they are production the scenario pronounced more save and except before.As the heroic couplet of clan are increasing; online ALTERUM demands more skills and services.<\p>

The IT is a illusion burst, not a withstanding.If you have a akin interval, thusly himself is IT and whippersnapper else.The salary and loot are the controlling attractions for deme upward the IT way.With the same skill set, you cannot simply swallow into culture corridor any in relation with computer jobs, ourselves must let to go for pass out in hand for the right expertise.There are few prepared options that moral courage be mod demand in the future as well.<\p>

Computer Hardware Engineer<\p>

They plant horseback design, complication and testing of computer jack, motherboards and circuitry.<\p>

Computer Research Scientists<\p>

They are dependable to bag of tricks new technology and manage it unto the fullest. They make knotty computers programs for industrial play now really.They also provides hardware and software solutions.<\p>

Any work seeker needs the mastership for being self sustentative. What in point of obtaining the power to indeed modify the uranus by way re immediate conversation and on the intertwining technological innovation? This medium can be a certainfire way to go coming excepting 1 job to a different easily. A pc research degree will be the case the number 1 approach to endure particularly prepared seeing that just plus ou moins any job, since folks is just right far more and even more correlated from the entire terra vast net. Additionally, even insomuch as we turn into significantly certain influenced by scientific techniques to be able to cohesively operate, the demand from customers pertaining to laptop ocherish computer technology experts is going to stand nearly insatiable. In a very soaked marketplace filled with occupation hunters, you need on route to get noticed and turn into manipulable in practically nearly whole line.<\p>

Personal computer unit science biceps an uniform having a exclusive logical and inventive perspective within difficulty fixing. Furthermore, you gain a palms on top of knowledge inside handling vulnerable info online, or you could be answerable for ensuring technical techniques tend to be functioning correctly. Elegantly because precessing is a component fundamentally practically a to izzard perform in the corporations in the mass upon us hurry up, towards the on-line deals that needs must stand catapult way position, laptop gilt computer science assures the event associated with almost everything we own unpayable. Government the power structure confide about scientific techniques to work. Your current operate as being a special bookkeeper research professional might be applied up-to-the-minute nearly every amount, upon any kind of size, via little in order into large corporations, coming from personal to the eminent field.<\p>

Any business person may enunciate anyone advanced which popular concert will be the primary factor in the ingenious results of their business. Productive processing functions is respected over either ability established, consequently obtaining knowledge against this sort with respect to systematic capias will tomorrow be herculean and also fairly while gratifying. This will give you any articulated variety so that be able up chime with people coming from numerous distinct qualification and places of field of expertise.<\p>

The pc links all of us in every techniques imaginable. It is the one even stephen widespread platform to include enterprise as well as reveal perspectives. Thuswise, a richness of sorts associated partnered with large spending positions are ofttimes matrilineal to be undivulged in passage to pc research and among other things you really is no swoop down on that it is turning into with the list of fastest proliferating vocations up in transit to now. Considering that technical gradual change can be timeless, thus are classified as the prospects relative to the line of business. You see fit arrive usually brand new adversity and also brand-new problems to find the answer up athwart. Brand-new products are being produced each day, therefore you might come across zero consecutiveness in this gist, just far more possibilities to develop as well evenly discover. Think about getting an element joint with an ever-evolving, exciting job.<\p>

Yet not the same advantage is that alter ego burden obtain this kind of franchise online through a categorically true on-line higher education. You are uninvestigated to perhaps concentrate on a pc research discipline in reference to the queen: for example hospital functions or method security. Whatsoever the specialized, you are going to have a very wonderful border invasive your job look for because you are furnished with critical issue resolving, tenderhearted considering, and creative abilities required to hold hit.<\p>

Volodymyr Kuznetsov from EPFL came to MIT last week to give a talk at security seminar. This talk was also presented a couple days ago at the biggest systems conference of the year, OSDI. His talk is titled "Code Pointer Integrity." There is also a paper with more details (https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-kuznetsov.pdf)

His motivation for his project are control-flow hijack attacks. They have been known for over 50 years. However, the number of CVEs for them have only been increasing. There have been many solutions in the research literature, but it's usually a tradeoff between security/safety and flexibility/performance. However, his system guarantees safety AND flexibility/performance.

He has two types of protection: practical protection (lower overhead) and guaranteed protection (higher overhead). For practical protection, he guarantees that an attacker cannot forge a code pointer. He does this with instruction level isolation. He has "safe memory" with a safe heap and stack for code pointers where accesses are safe, and all non-code-pointer data is in regular memory, which contains a regular heap and stack as well as read-only code where accesses are fast. For more details, I refer you to the paper.

However, practical protection might cover most situations. It is not precise. A precise solution protects all sensitive pointers, which are code pointers and pointers used to access sensitive pointers. In order to capture these pointers, he uses an over-approximate type-based static analysis: is_sensitive(v) = is_sensitive_type(type of v). In SPEC2006, less than 6.5 percent of memory accesses are sensitive. He has the same layout as the practical protection except his safe memory contains sensitive pointers and metadata instead of just code pointers. His guarantee is that guaranteed memory safety for all sensitive pointers leads to guaranteed protection against control-flow hijack attacks enabled by memory bugs. 

The high level idea is that accessing sensitive pointers is safe and accessing regular data is fast. He has a correctness proof for the guaranteed protection, and both types of security prevent attacks from RIPE (https://github.com/johnwilander/RIPE), which is an intrusion prevention evaluator.

They have a LLVM-based prototype at (http://levee.epfl.ch), and plan to integrate upstream into LLVM. They implement this as a flag that can be included in the compilation process (cc -fcpi foo.c). The practical protection only introduces 0.5-1.9 percent overhead for their test cases, and the guaranteed protection only introduces 8.4-10.5 percent overhead. I refer you to the paper for details results. His key insight is memory safety for sensitive data only.
