kraemate··on Nvidia Becomes First Company to Reach $4T Market Cap
Wow, who knew making proprietary accelerators could be so profitable.
kraemate··on Researchers craft a fully edible battery
Its called a fruit?
kraemate··on Microtargeting as Information Warfare [pdf]
So, are people who work for microtargeting platforms (FB etc) war criminals?
kraemate··on Apache Mesos to be moved to Attic
IIRC you could always overcommit in Mesos using DRF weights and accepting resource offers in your application. I could be wrong.

The larger point is that Mesos introduced a new, exciting way to do truly distributed allocation (where the cluster manager (i.e., Mesos) and various applications coordinated and cooperated in how they use computing resources). In contrast, Kubernetes is centralized, pretty vanilla, and I would love to know what new ideas it has introduced (from an algorithmic and architecture perspective).

kraemate··on Apache Mesos to be moved to Attic
Mesos made a ton of new contributions to distributed resource management. Resource offers and application integration can allow high cluster utilization and efficiency. Giving applications the opportunity to take part in resource allocation and scheduling was similar to the Exokernel design, and led to many interesting middleware architectures.

Mesos also introduced Dominant Resource Fairness for allocating resources to competing applications, which has become an important concept in CS and specifically computational economics in its own right.

Mesos achieved the rare combination of using CS research towards a widely deployed operational system. Its C++ code is simple enough to understand and hack, and seemed like one of those projects that you can/want to reimplement on your own "in a few days".

It is sad how quickly it has become obsolete.

kraemate··on Why I’m Losing Trust in Open Source
In almost all cases, the support of these giant corporations is towards feature-sets that are inherently self-serving. In many cases, they wield too much power and hijack the direction of the opensource projects. For example, there's plenty of optimizations for server-side CPU performance on Linux, often to the detriment of desktop interactive performance (see Con Kolivas' scheduler and his 10+ year long struggle).
kraemate··on Elon Musk wants clean power. But Tesla's carrying Bitcoin's dirty baggage
You can apply this logic for any wasteful activity. Lets boil the ocean with coal-fired plants, because something something production vs. consumption.
kraemate··on Reddit valued at $6B on a $250M round
Sorry, why is this downvoted? There is a serious argument to be had about the source of income for surveillance and tracking driven websites. If the oft-used line of "users being products" is true, then where's our profit?
kraemate··on Reddit valued at $6B on a $250M round
So, do its main revenue generators (i.e., users) get a share of the profits?
kraemate··on CSI-MURDER: Prevent WiFi CSI from being used to survey environment
It's in the paper: https://github.com/seemoo-lab/csicloak
kraemate··on Multiway Turing Machines
Very interesting and different way to "visualize" non determinism. The connection to quantum mechanics is intriguing...
kraemate··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
He is the richest person in the world. Such trivial rules dont apply to him...
kraemate··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
It is Elon Musk---why would he care about the proles' "environment"
kraemate··on GraphScope: A One-Stop Large-Scale Graph Computing System
I have always wondered what common usecases such systems address. How large are the graphs typically? Are graphs really that big that they dont fit in a single machine?
kraemate··on Firecracker – Lightweight Virtualization for Serverless Computing
OK I had missed the kata containers blurb in the FAQ, thanks for pointing it out. In fact the tweets make my point: we are all so blinded by new shiny releases that we forget their highly incremental nature.
kraemate··on Firecracker – Lightweight Virtualization for Serverless Computing
Clear containers (now called kata containers) did this more than three years ago, with similar performance numbers (sub 200 ms boot times). It is frustrating, but not surprising, to see the same regurgitated solution receive this much excitement. The firecracker documentation also does not mention the similarity with prior work, oh well.

[Not affiliated with Intel in any way---just a long-time proponent of the clear containers approach.]

kraemate··on My VM is lighter and safer than your container
How many custom kernels are out there?

Given the already sad state of most user-space software, do we really want a proliferation of supposedly light-weight kernels?

kraemate··on Multipath TCP Check
MPTCP's bandwdith aggregation properties are cool---you can effectively use all your network interfaces for (MP)TCP connections.

Has anyone deployed it in data-center/cloud environments? I know that both Apple and Android support it for the mobile devices to use WiFi and LTE at the same time.

kraemate··on Ggplot2 – The code powering all those excellent charts is 10 years old
I've always wanted to switch from python's matplotlib to ggplot, but never found sufficient advantages to make the switch. Especially considering that I use python for doing data analysis, and pandas+ipython-notebook can be tightly integrated with matplotlib.

Plus I've found it easier to create compact figures necessary for academic publishing with matplotlib. ggplot's defaults create graphs that take up too much space!

kraemate··on Containers vs. Zones vs. Jails vs. VMs
We wrote a paper comparing containers and VMs for the middleware conference: http://people.cs.umass.edu/~prateeks/papers/a1-sharma.pdf
kraemate··on Space Radiation Devastated the Lives of Apollo Astronaut
Infact, Table-1 in the paper confirms this. The astronauts that went to the moon lived significantly longer (65 compared to 56 years).
kraemate··on Space Radiation Devastated the Lives of Apollo Astronaut
What about the relative lifespans of the astronauts? The ones selected to go to the moon were probably older, fitter, and more experienced when they made the trip. Did they outlive the other astronauts and the general population? Since mortality due to heart disease increases with age, did the moon astronauts just live longer?
kraemate··on Hammerspoon – Powerful automation of OS X with Lua
I have always lamented the lack of such automation techniques on Linux. Even though Linux systems are open and free software platforms, their desktop interfaces are ironically less programmable as compared to OSX and Windows.
kraemate··on Ask HN: How do you handle transferring large files over the internet?
Wow, thanks for the script. Surprising in its simplicity. I would have thought this use-case was popular enough to warrant specialized tools etc. Especially in the scientific community where they transfer large files.
kraemate··on Ask HN: How do you handle transferring large files over the internet?
Does rsync auto-resume after failed connections?
kraemate··on Postfix has no public version control
The first poster in that thread was just asking for trouble, bringing that know-it-all attitude.
kraemate··on A Motion-Sensing Keyboard
What can this do that cant be done with a keyboard shortcut?
kraemate··on Facebook's new optical storage solution [video]
Surely, credit-card info can't span 100s of terabytes, even if they record each and every transaction.
kraemate··on Facebook's new optical storage solution [video]
Does anyone know what data is Facebook trying to archive? Old user posts? But that doesn't fit this usecase because of the high latency.

Or maybe its just a nice content delivery mechanism to the NSA. Just ship a bunch of blue-rays instead of pesky optical fiber interception.

kraemate··on Netflix uses FreeBSD 9.0
I'm confused, doesn't Netflix use AWS for all their servers? AFAIK you can't run FreeBSD on EC2 without significant challenges.
