More protocols and utilities are coming soon, so stay tuned.
The C99 libraries are already included for your convenience as submodules. You should perform a recursive clone git clone --recursive
or initialize the submodules via git submodule update --init
. These dependencies are compiled by CMake as part of the build process.
If you want to manage these dependencies manually (e.g. you're using them in other projects), configure CMake with -DBUILD_DEPS=OFF
and -DCMAKE_PREFIX_PATH=<install>
pointing to the absolute path where you have them installed.
If you want to use a statically linked MSVCRT (/MT, /MTd), you can add -DSTATIC_CRT=ON
to your cmake configuration.
There are no non-OS dependencies that AWS does not own, maintain, and ship.
To do anything with IO, you'll need to create a few objects that will be used by the rest of the library.
For example:
Will load error strings for debugging purposes. Since the C libraries use error codes, this will allow you to print the corresponding error string for each error code.
This performs one-time static initialization of the library. You'll need it to do anything, so don't forget to create one.
To use any of our APIs that perform IO you'll need at least one event-loop. An event-loop group is a collection of event-loops that protocol implementations will load balance across. If you won't have very many connections (say, more than 100 or so), then you most likely only want 1 thread. In this case, you want to pass a single instance of this to every client or server implementation of a protocol you use in your application. In some advanced use cases, you may want to reserve a thread for different types of IO tasks. In that case, you can have an instance of this class for each reservation.
If you plan on using TLS, you will need a TlsContext. These are NOT CHEAP, so use as few as possible to perform your task. If you're in client mode and not doing anything fancy (e.g. mutual TLS), then you can likely get away with using a single instance for the entire application.
Lastly, you will need a client or server bootstrap to use a client or server protocol implementation. Since everything is non-blocking and event driven, this handles most of the "callback hell" inherent in the design. Assuming you aren't partitioning threads for particular use-cases, you can have a single instance of this that you pass to multiple clients.
Please note that on Mac, once a private key is used with a certificate, that certificate-key pair is imported into the Mac Keychain. All subsequent uses of that certificate will use the stored private key and ignore anything passed in programmatically.

L5: FIRST CITY IN SPACE A film review by Mark R. Leeper Copyright 1997 Mark R. Leeper
Capsule: The first science fiction film in IMAX 3-D is the curiously subdued story of a rather prosaic mission to help maintain the L5 colony. The process may be more interesting than the rather sterile and idealized view of life on the nearly self-sustaining space colony. But besides the size of the screen there is little in the process that was not present in 3-D films of the 1950s. Rating: low 0 (-4 to +4)
Back in the 1950s and 60s the film industry wanted to give the public something they could not get on TV. They invented a wide-screen process using three strips of film and a screen that wrapped around the audience. The process was called "Cinerama." And the films made in this process were mostly just demonstration films to show what could be done. The films had names like THIS IS CINERAMA, CINERAMA HOLIDAY, WINDJAMMER, and THE SEVEN WONDERS OF THE WORLD. Eventually the public got bored with just picturesque documentaries and the filmmakers had to start putting plots into the films, but they kept them simple and episodic with big action sequences. After all audiences did not need Cinerama for MACBETH. They wanted exciting action sequences. So they made films like HOW THE WEST WAS WON which was really more a set of short stories which featured thrill scenes like runaway stage coaches. THE WONDERFUL WORLD OF THE BROTHERS GRIMM actually had a story that went the length of the film, but it also had sequences of fairy tales. The films were intentionally kept big and kind of stupid to make the best use of the process. The final film I remember being made in the process was supposed to take the viewer on a scenic ride into space. I suspect it was originally intended to be that and to have only the faintest whisper of a plot. It was given a kind of vacuous name to imply that it was a sort of WINDJAMMER in space. It was to be called 2001: A SPACE ODYSSEY. By the time this film was finally made some of the people behind it had sort of meddled with the concept a little. For one thing it was not really an odyssey any more, but it was still a sort of futuristic, science-fictional demonstration of the new medium. And it proved to be the most popular of the Cinerama films.
For the new IMAX 3-D process they did not wait so long to try science fiction. One of their first films is a voyage into space. And not to mix my analogies, but just as the film THE CONQUEST OF SPACE was heavily based on a speculative non-fiction book, THE CONQUEST OF SPACE by Willy Ley, L5: FIRST CITY IN SPACE is based heavily based on Gerard K. O'Neill's THE HIGH FRONTIER, in which the author describes in detail a mammoth space station that will be placed at the L5 point. L5 is a point first described by the mathematician and astronomer Comte Joseph Louis Lagrange which will hold onto matter in a stable equilibrium. As soon as the matter starts to move away from the point gravitational forces from the Earth and the Moon will pull it back. A space colony placed at the L5 point will need to expend no energy to remain at the that point. O'Neill described a sort of perfect world, nearly self- sufficient, hanging in space at the L5 point. L5: FIRST CITY IN SPACE is a story set in this future world.
Director Toni Myers seems to share Stanley Kubrick's belief that in space the furniture will not be wooden but all the people will be. The story seems to be performed by catatonics. There is not a lot to the story here, since the entire film is only 34 minutes long (and sports a hefty ticket price of $9). The film starts with a sort of tour of the interior of the L5 station, much as it was described in THE HIGH FRONTIER. Interiors are short live-action but the exteriors are done in 3-D animation, but using art very much the style of O'Neill's illustrations. We meet Chieko, a little girl living in the L5 colony with freshets of water feeding long rows of perfect palm trees, hydroponically grown to produce perfect fruit of exotic types. But her parents and grandfather are worried (note the worried expressions on their faces). The L5 colony has a problem, just about the most prosaic problem imaginable. It is not the same problem that plagued the runaway forest in SILENT RUNNING, but it is just as basic and it is just as amazing that it takes the characters by surprise. But it is a serious problem, enough so that the actors can look worried. Fixing the problem involves travel to a comet that happens to be hurtling by. But the story is told with little dramatic tension in explaining threat so there is not much excitement. There is just quiet worry that is eventually alleviated.
Among the things that bothered me about the film was that in the exteriors the stars seemed to be in 3-D with some appearing closer than others. In a word we got parallax on stars. This is a total absurdity added to use the 3-D effect. The film shares the book's optimism that everything on the L5 colony would be just about ideal. The fruit grown from hydroponics is just perfect looking. And even the view of Earth from the colony is perfect and beautiful. On the dark side the cities show up as perfect little jewels of bright light. I could believe some pinpoints, but not as big as the film shows them to be. The final unlikely element is the presence of a Holodeck sequence--I know of nothing else to call it--whose technology is unexplained.
Some comments should be made about the IMAX 3-D process itself. First the screen in New York seems smaller than other IMAX screens I have seen, at least as I remember them. Even sitting close to the screen, due to arriving late, I could see both edges at the same time. The fact that we are seeing a 3-D process makes the screen look even smaller. I do not know exactly why that is, but 3-D processes I have seen seem to make the screen look smaller than it looks without the goggles or glasses. This 3-D process is actually quite primitive, in spite of the supposedly advanced presentation. The goggles use simple polarized lenses and if one tips ones head only the slightest, a ghost image comes into view. The ghost image often would show up even without tipping. The 3-D process, in short, presented little technology that was not present for DIAL M FOR MURDER in 1954.
It is not clear that you can rate a little demonstration film like it was a feature film in a more standard theater, but this one satisfied like a film that would have gotten a low 0 on the -4 to +4 scale.

Alcohol |
(liquid) |
The first time I drank alcohol, I was 14 years old. During my freshman year of high school, I began dating a boy named C. One Friday night he and I went to a party. C was a junior, older than I, and his friends were big metal heads who drank and smoked and did drugs while listening to Pantera. I had never had alcohol at that point, but when C offered me a beer, I accepted it.
He got me a Beck's (I'm a vegan) and a Coors for himself. My first sample made me grimace a bit. It tasted like a stale, bitter tea but after a couple of mouthfuls, I got used to it. An hour later, I had finished 3 bottles of the stuff.
Three beers may seem petty even for a first time drinker, but for a little girl on an empty stomach, it was excessive. I began feeling nauseous and dizzy and my head was pounding. When I went into the bathroom, I saw my reflection, pale and sweating in the mirror. I told C I wasn't feeling well and he drove me home. He helped me up to my room and stayed with me until I fell asleep.
When I woke up at around 2 in the morning, the first thing I did was run to the bathroom and vomited. Up the beer came, looking not much different than it had when I first drank it. After successfully emptying myself of the horrid stuff, I took a shower, dressed in clean clothes and went back to sleep.
Due to the less than wonderful reaction I had with alcohol my first time, I stayed away from alcohol for a time. The following summer though, my own friends started drinking. Whenever they offered me a beer or a shot, I always turned it down. This usually meant I was the only sober one of the group, but it never bothered me much. They knew of my last unfortunate experience with alcohol, but blamed it on the beer being bad or something of that sort.
So I agreed to give it another try. B, W, L, M and A won the rights to 'pop my drinking cherry' after a tumultuous rock-paper-scissor battle. We all gathered in W's room with a big bottle of Jack Daniels and 6 shotglasses and started drinking. They knocked back their shots like nothing. Hard liquor tasted even worse than beer, I figured out. Beer was unpleasant, but at least it didn't burn a hole in my throat on the way down. To the delight of my friends, I drank my first glassful like someone would with tea, sipping it tentatively and ended up coughing.  It still burned like mad and tasted disgusting, but I kept drinking anyway.
I can't recall how much time passed, but it was a lot. I had 8 shots and the rest of them had done about 12 or 13.  But I wasn't feeling drunk at all. Just sort of sleepy. And my legs felt heavy. No double vision or incoherent slurring. I wondered if something was wrong with me.
And then suddenly, it hit me. All of a sudden I felt very, very, very sick.  I felt as if I was going to die. The ground beneath me began twirling and the mouths of my friends were not coinciding with the words they were speaking. It was like one of those scenes in a movie just before the character blacks out. I swayed, no longer having enough balance to sit up straight and Derek caught me before I hit the floor. I looked up at him and said quite placidly 'I feel ill'.
As tanked as they all were, they somehow got together enough coordination to get me to the bathroom. B carried me to the toilet and two seconds later, with someone carefully holding back my hair, I threw up violently for what seemed like forever. My stomach heaved up the rejected liquor repeatedly until I was weak and empty and half dead.
 I brushed my teeth and washed my face and went downstairs to the living room to find five guys sleeping in their boxers with the porn channel still playing on the television. I cannot remember the rest of the night too lucidly, but from what I heard they called my parents and told them I was sleeping over at W's. Then they carried me into his bedroom, tucked me into bed, debated whether or not to undress me and in the end, took off my shoes and left a wastebasket next to the bed.
It's been 3 years since that incident and to this day, I rarely drink.  I don't mind not drinking at parties even though everyone else around me for miles is chugging down beer and vodka. I am the ultimate non-drinker.
Maybe in my next life, I can be an alcoholic.

One of the annoying features of PowerShell is that the Stop-Service

and Restart-Service
cmdlets don't have ComputerName
parameters to start/stop/restart a service on a remote computer. You have to use Get-Service
to get the remote service:
$service = Get-Service -Name DeathStar -ComputerName Yavin

$service.Start()
# or (and no, you can't pipe the service directly to `Restart-Service`)

SapphireDb comes with an alternative for controllers. They are called ActionHandler. You can use them like
controllers in Asp.Net. You can define public methods that are exposed through the sapphire interfaces.
Basic example
Just create a class in your project and derive it from ActionHandlerBase.
You can use dependency injection in the constructor of the class.
The methods allow any serializable return type and you can also use async methods.
Calling the methods on client side is pretty easy. Just pass the name of the handler as first parameter and the name of the method as second.
Every other parameters will be used as parameters for the method.
Stream data from server
You can also stream async data from server to client.
Streaming data from client to server is also possible. It is also possible to do both.
();\n
this.streamValueResponse$ = this.db.execute('example.StreamTest', subject$);\n
subject$.next('value');\n
subject$.complete();
\f:(csharp:AsyncActions.cs:Server)
public class AsyncActions : ActionHandlerBase\n
{\n
\tpublic async IAsyncEnumerable StreamTest(IAsyncEnumerable inputStream)\n
\t{\n
\t\tawait foreach (string input in inputStream)\n
\t\t{\n
\t\t\tyield return input + " from server";\n
\t\t}\n
\t}\n
}
]]>
Notifications
Because SapphireDb allows a bidirectional communication between client and server you can also send additional
notifications during method execution. This is useful to transfer a state for example.
Use the Notify-method in your action handler to achieve that.
The client side can use the action helper to distinguish between notification and final result.

'We can’t sit idly by'; Feinstein cosponsors Horseracing Integrity Act
by Press ReleaseCalifornia Sen. Dianne Feinstein released the following statement after joining as a cosponsor of the Horseracing Integrity Act, a bipartisan bill introduced by New York's Kirsten Gillibrand and Arizona's Martha McSally to end doping of American racehorses and create a uniform national standard for drug testing.
“I’m cosponsoring the Horseracing Integrity Act because it’s past time that we end the rampant doping that plagues horse racing and is contributing to racehorse fatalities.
“Drugs, including the much-prescribed Lasix, allow trainers to mask illnesses and push horses beyond their physical limitations. The result is too often a catastrophic injury requiring the horse to be euthanized. There is no reason a healthy horse should need drugs to race.  Period.
“The tragic deaths of racehorses at Santa Anita and Del Mar only scratch the surface of the sport’s serious issues. Doping is a problem bigger than any track. It demands a national solution.
“Banning doping is one of the biggest steps we can take to clean up the problems with horse racing. It will save horses’ lives, and that’s something we should all support.”
Key provisions of the bill:
• Establishes a uniform, national standard to prohibit doping and medication for racehorses. Currently, each state establishes its own, creating a patchwork of standards.
• Creates a new independent body to oversee the use of drugs and medication on racehorses. This body would be overseen by the U.S. Anti-Doping Agency and have the power to make rules, testing requirements and enforcement mechanisms.
• Immediately bans Lasix (furosemide) and other medications dangerous to racehorses. It also requires international anti-doping and medication control standards to be considered when developing a U.S. anti-doping program.

Fran Bartolic (2020-)
I advised Fran Bartolic as part of the
CCA
pre-doctoral program. Fran is a graduate student at the
University of St. Andrews working on microlensing and statistical
methods for astronomy. Our project, however, was somewhat outside both Fran's
and my
wheelhouse: mapping volcanoes on the surface of Io, the moon of Jupiter.
There is a lot of high-quality archival data on occultations of Io by Jupiter
and the other
Galileian moons (Europa, Callisto, and Ganymede), which Fran used to infer the
locations and brightnesses of the main volcanic regions on the moon. The
significance
of this project lies in the fact that (1) we know the ground truth to some
extent
from fly-bys of Io, so it's a great benchmark for exoplanet secondary eclipse
mapping
in the near future; and (2) we don't know the ground truth
all that well, since Io's surface is
constantly
evolving. Fran is working on a joint analysis of all observations of Io to
infer the time evolution of the surface in a principled, Bayesian way, which
could lead to new insights into the physics of the moon's interior and its tidal
interaction with Jupiter.

Organized chaos: managing randomness
This post gives a bit of background on the Random Number Generator (RNG) in the recent MirageOS v2.5 release.
First we give background about why RNGs are really critical for security. Then we try to clarify the often-confused concepts of “randomness” and “entropy”, as used in this context. Finally, we explore the challenges of harvesting good-quality entropy in a unikernel environment.
Playing dice
Security software must play dice.
It must do so to create secrets, for example. Secrets can then serve as the keys that protect communication, like the Diffie-Hellman key exchanged between two TLS endpoints. Proof of the knowledge of a particular secret can be used to verify the identity of someone on the Internet, as in the case of verifying the possession of the secret RSA key associated with an X.509 certificate. As an attacker guessing a secret can have disastrous consequences, it must be chosen in a manner that is realistically unpredictable by anyone else — we need it to be random.
There are other reasons to use randomness. A number of algorithms require a
unique value every time they are invoked and badly malfunction when this
assumption is violated, with random choice being one way to provide a value
likely to be unique. For example, repeating the k
-parameter
in DSA digital signatures compromises the secret key, while reusing a
GCM nonce negates both confidentiality and authenticity. Other
algorithms are probabilistic, in that they generate random values before
operating on an input, and then store the chosen values in the output, such as
the OAEP padding mode for RSA. This is done in order to confuse the
relationship between the input and the output and defeat a clever attacker who
tries to manipulate the input to gain knowledge about secrets by looking at the
output. Still other algorithms pick random numbers to internally change their
operation and hide the physical amount of time they need to execute, to avoid
revealing information about the secrets they operate on. This is known as
blinding, and is one way to counter timing side-channel
attacks.
Randomness is therefore quite pervasive in a security context. In fact, many cryptographic algorithms are designed under the assumption of a readily available source of randomness, termed a random oracle. The security analysis of those algorithms is conditional on the oracle; we know that they have certain security characteristics, like the difficulty of guessing the correct message or impersonating somebody, only given an ideal random oracle.
And so security software has a problem here. Computers are inherently deterministic, made to behave reproducibly given a known program and starting state. How to go about solving this?
Random failures
Before taking a look at how we try to solve this problem, let’s instead consider what happens if we fail to do so. There is even a Wikipedia page about this, which is a nice starting point. Some of the highlights:
The first public release of Netscape’s original SSL, version 2.0, was broken several months after its release. The weakness was in initializing the RNG with the current time, the process ID and the parent process ID of the browser. The time stamp can be guessed to a certain precision, leaving only its sub-second part and the two PIDs unknown. This relatively small unknown space of initial values can be brute-forced.
About a decade later, Debian patched their version of OpenSSL and reduced RNG initialization to the current PID. As a result, only 32767 random sequences were possible. This flaw went undetected for two years and became known as the Debian fiasco. Personal reports indicate that some of the 32767 distinct secret keys that could be generated with OpenSSL on a Debian system during that time are still in circulation.
Computing the largest common divisor of a pair of numbers is much faster than discovering all the prime divisors of a particular number. RSA public keys contain a number, and secret keys contain its factors. An RSA key is usually generated by randomly picking the factors. If a pool of keys was generated with a heavily biased random number generator, such that factors are likely to repeat, it is possible to search for common factors in all pairs and crack the affected keys, a technique which produces spectacular results.
Recently, a bitcoin application for Android was discovered to be downloading its random initial value from a website. It wasn’t even necessary to intercept this unencrypted traffic, because the website started serving a redirect page and the Android application was left initializing its RNG with the text of the redirection message. It therefore started generating the same private ECDSA key and the associated bitcoin address for every affected user, an issue which reportedly cost some users their bitcoins.
Playstation 3 game signatures can be forged. Sony reused a
single k
-parameter, which is supposed to be “unique, unpredictable and
secret”, for every ECDSA signature they made. This lead to complete compromise
of the signing keys. Admittedly, this is not really an RNG
problem in itself, but it shows where such a malfunction can lead.
These are only some of the most spectacular failures related to random numbers. For example, it is widely known in security circles that RNGs of embedded devices tend to be predictable, leading to widespread use of weak keys on routers and similar equipment, amongst other things. So when implementing a unikernel operating system, you don’t want to end up on that Wikipedia page either.
Random sequences and stuff
But what are random numbers, really? Intuitively, we tend to think about them as somehow “dancing around”, or being “jiggly” in a sense. If we have a software component that keeps producing random outputs, these outputs form a sequence, and we hope this to be a random sequence.
But such a thing is notoriously difficult to define. The above linked page opens with the following quote:
A random sequence is a vague notion… in which each term is unpredictable to the uninitiated and whose digits pass a certain number of tests traditional with statisticians.
The intuitive jigglyness is captured by statistical
randomness. We require each output, taken
independently, to come from the same distribution (and in fact we want it to be
the uniform distribution). That is, when we take a long sequence of outputs, we
want them to cover the entire range, we want them to cover it evenly, and we
want the evenness to increase as the number of outputs increases — which
constitutes a purely frequentist definition of randomness. In addition, we want
the absence of clear patterns between outputs. We don’t want the sequence to
look like 7, 8, 9, 10, ...
, even with a bit of noise, and we
don’t want correlation between outputs. The problem here is that no-one really
knows what “having patterns” means; it is entirely possible that we only
searched for patterns too simple, and that in fact there is a pattern that fully
explains the sequence lurking just around the complexity corner.
Nonetheless, there is a well established battery of tests to check statistical randomness of RNG outputs, called the Diehard Tests, and serves as the de-facto standard for testing random number generators. Here’s the beginning of a certain sequence that passes the test with flying colors:
3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9, 3, 2, 3, 8, 4, 6, 2, 6, 4, 3, 3, 8, 3, ...
We still would not recommend using digits of π
as a secret key.
Neither would we recommend
releasing software for everyone to study, which uses that sequence to generate
the secrets. But what went wrong?
The other concept of randomness. Roughly, a random sequence should not be predictable to anyone with any knowledge other than the sequence itself. In other words, it cannot be compressed no matter how much we try, and in the extreme, this means that it cannot be generated by a program. While the latter restriction is obviously a little too strong for our purpose, it highlights a deep distinction in what people mean by being “random”. Jumping around is one thing. Being actually unpredictable is a wholly different matter.
There are many other simple mathematical processes which generate sequences with high statistical randomness. Many of those are used to produce “random” sequences for various purposes. But these are still completely deterministic processes that exhibit random behaviour only in the statistical sense. Instead of being random, they are pseudo-random, and we call such generators Pseudo-Random Number Generators (PRNGs).
We can look for something approaching a “true” random sequence in nature. The current agreement is that the nature of quantum processes is random in this sense, and random sequences based on this idea are readily available for download. Or we can use the microphone and keep recording; the lowest-order bits of the signal are pretty unpredictable. But we cannot write a program to generate an actually random sequence.
Still, we need to compromise. The real problem of common PRNGs is that knowing the rule and observing some of the outputs is enough to predict the rest of the sequence. The entire future behavior of Mersenne twister, one of the most commonly used generators in various programming packages, can be predicted after observing only 624 outputs in a row. A step up from such a process is a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG). Their key property is that it is computationally prohibitively expensive to distinguish their outputs from a “true” random sequence. This also means that it is computationally prohibitively expensive to reconstruct their internal state, just by looking at their outputs. In a sense, someone trying to predict the outputs can not take shortcuts, and is instead forced to perform the laborious task of starting the generator with all the possible states and checking if the output matches the observed sequence. This is how we can quantify a CSPRNG unpredictability: it takes trying about half of all the possibilities to guess the state.
MirageOS’ security stack contains a CSPRNG, a design called Fortuna.
What it really does, is encrypt the simple sequence 0, 1, 2, 3, ...
with AES
(AES-CTR) using a secret key. This makes it as resistant to prediction as AES is
to known-plaintext attacks. After each output, it
generates a bit more, hashes that, and uses the result as the next key. This is
not to improve the statistical randomness, as it is already guaranteed by AES.
Rather, it’s a form of forward secrecy: an attacker who
learns the secret key at some point would need to perform the preimage
attack on the hash function to figure out the earlier key
and reconstruct the earlier outputs.
Entropy
Although resistant to prediction based solely on the outputs, just like any other software RNG, Fortuna is still just a deterministic PRNG. Its entire output is as unpredictable as its initial value, which we call the seed. From the information perspective, a PRNG can only transform what was unpredictable about its initial seed into an equally unpredictable sequence. In other words, we typically use PRNGs to stretch the unpredictability inherent in the initial seed into an infinite stream. The best PRNGs do not give out more hints about their starting position, but they can never out-race the amount of unpredictability that they started with.
We often call this quality of unpredictability entropy. In a sense, by employing an algorithmic generator, we have just shifted the burden of being unpredictable to the beginning. But now we’re cornered and have to search for entropy in the only place where a computer can find it: in the physical world.
A typical (kernel-level) RNG-system reaches out into the world around it through hardware interaction: as hardware events happen, various drivers tend to emit small packets of data, such as the time, or hardware-specific state. These events are a product of the user interactions with the keyboard and mouse, of network packets arriving at an interface, of the hard drive asserting interrupts to signal the end of a DMA transfer, and the like. They are combined together and used to seed the internal (CS-)PRNG.
In fact, describing them as a seed from which the entire sequence is unfolded is a deliberate oversimplification: what really happens is that the PRNG is continuously fed with random events, which change its state as they arrive, and the requests for random bytes are served from the PRNG. The PRNG is used to “mix” the unpredictability inherent in its input, that is, to smooth out various timestamps and similar values into a statistically well-behaved sequence.
Do Virtual Machines Dream of Electric Sheep?
Our problem here is that a virtual machine (VM) in a typical configuration barely sees any physical hardware. Users do not interact with VMs in server scenarios using a directly-connected keyboard and mouse. VMs make use of a virtualized network interface and virtualized disks. Even the CPU features can be intercepted and virtualized. Virtual environments are entropy-starved.
This is a known problem and various analyses of the weakness of random outputs in virtual environments have been published. The problem is especially severe right after boot. The gradual trickle of unpredictability from hardware events slowly moves the pseudo-random stream into an increasingly unpredictable state, but at the very start, it still tends to be fairly predictable. Typically, operating systems store some of their PRNG output on shutdown and use it to quickly reseed their PRNG on the next boot, in order to reuse whatever entropy was contained in its state. Unfortunately, it is common to boot several machines from the same system image, or from a pristine image lacking a seed, making random outputs in a virtual machine vulnerable to prediction close to the startup phase.
To help solve these problems, we employ several sources of entropy in MirageOS
unikernels. The case of a Unix executable is simple, as we reuse the system’s
own RNG, as exposed via /dev/urandom
, as the source of our entropy. This is
because the kernel is in a much better position to enter an unpredictable state
than any single process running under its supervision. The case of Xen
unikernels is harder. Here, we group the entropy sources into those that
originate within the unikernel itself, and those that originate externally.
In the external case, we again rely on the kernel interacting with the hardware, but this time it’s the dom0 kernel. We have a background service, Xentropyd, which runs in dom0, reads the RNG and serves its output to other domains through the Xen Console. The problem is that in many scenarios, like hosting on popular cloud providers, we cannot expect this degree of cooperation from dom0. A bigger problem is that although most of the code is present, we haven’t fully fleshed out this design and it remains disabled in MirageOS 2.5.0
So we need to be able to achieve unpredictability relying purely on what is available inside a unikernel. A unikernel has no direct exposure to the hardware, but it is of course interacting with the outside world. To tap into this ambient entropy, we have to continuously sample all inter-event timings in its event loop. This process is analogous to what happens in a full-blown OS kernel, except our events lack the extra hardware context, and our timers are potentially less granular (for example, on ARM). This makes our interaction-based events somewhat more predictable, or in other words, they have a little less entropy.
Recent Intel chips come with an on-die random generator, which ultimately
derives from thermal readings, and is available through RDRAND
and (more
directly) RDSEED
instructions. The community has expressed concern that
relying exclusively on this generator might not be a wise choice: it could
silently malfunction, and its design is hidden in the hardware, which raises
concerns about potential intentional biases in the output — a scheme not
unheard of. However, since entropy is additive, its output can never
reduce whatever unpredictability the system already has. Therefore, if
available, we continuously sample this on-die RNG, and inject its outputs into
our PRNG.
The combination of event timings and a built-in RNG does have good unpredictability in the long run, especially if our unikernel is running on a multi-tenant host and competing for CPU with other instances. But the entropy in each individual event is still relatively low: we can assume that a determined attacker can guess each individual time stamp up to a certain precision that we don’t know, but which is potentially quite high. This creates the following problem: imagine that an attacker knows the current PRNG state, and can measure the time of the next event, but not with sufficient precision to know the last two bits of the timestamp. To this attacker, our event contains two bits of entropy. If we immediately update the PRNG, the attacker only has to observe some of the output and check four candidate states against it, to fully recover knowledge about the state and negate our entropy addition. On the other hand, if we decide to wait and try to accumulate many more events before updating the PRNG, we keep generating a fully predictable sequence in the meantime.
And here is where Fortuna really shines. It keeps accumulating events in a number of internal pools in a round-robin fashion. These pools are constantly being activated, but with an exponentially decreasing frequency. The pools activated too frequently are wasted, but one of them is activated with just the right frequency to contain enough entropy to make it prohibitively expensive for an attacker to enumerate all the possibilities. This design was shown to be within a constant factor from optimal entropy use, and in particular, scales robustly with the actual amount of entropy inherent in the input events.
This leaves us with the problem of boot-time entropy. Not only can the saved random seed be reused by cloning the disk image, but in many cases, a MirageOS unikernel is running without such storage at all!
Following the design of Whirlwind RNG, we employ an entropy bootstrapping loop. It’s an iterated computation, which measures the time it took to perform the previous iteration, and then performs the amount of work that depends on the time, many times over. In this way, it creates a feedback loop with a fragile dependency on any non-determinism in the physical execution on the CPU, such as any contention or races in the CPU state. Even on ARM, which currently uses a less fine-grained timer and whose design is not as parallel as Intel’s, this yields an initial value which varies wildly between boots. We use this value to kickstart the PRNG, giving it quick divergence, and ensuring that the state is unpredictable from the very start.
Parting words
While some of our techniques (in particular bootstrapping on ARM) need a little more exposure before we place our full confidence in them — and users should probably avoid generating long-term private keys in unikernels running on bare Xen just yet — the combination of boostrapping, continuous reseeding, and robust accumulation gives us a hopefully comprehensive solution to generating randomness in a unikernel environment.
We intend to re-evaluate the effectiveness of this design after getting some
experience with how it works in the wild. To this end, we particularly
appreciate the community feedback and

JACK and TIN CUP A film review by Jim Maguire Copyright 1996 Jim Maguire
JACK Starring : Adam Zolodin, Fran Drescher, Bill Cosby and Robin Williams. Directed by : Francis Ford Coppola.
TIN CUP Starring : Kevin Costner, Rene Russo, Don Johnson and Cheech Marin.
Directed by : Ron Shelton.
Comebacks. They mean something. A comeback can be better than it would be if the director or the star of the movie wouldn't have had two good back-to-back films.
Both Ron Shelton (COBB) and Francis Ford Coppola needed a comeback. Coppola needed one because he hasn't made a good film in ages, all the way back to APOLOCALYPSE NOW. Shelton, whose disaterous COBB made my top 5 worst films of the year, looked like it was made by a wild crazy lunatic who had no idea on the subject of filming. They both put forth movies now, TIN CUP for Shelton, and JACK for Coppola. It would seem that Shelton, whose name is not as catchy in Hollywood as Coppola's, would have a long way to come. But, Coppola panicked at the last second, and threw some hypier-sad fluff at us. Shelton played it cool, and therefore his movie just works. It works on every level.
Speaking about comebacks, need I mention Kevin Costner and Bill Cosby. Costner hasn't made a good film since DANCES WITH WOLVES, and he hasn't made anything thrilling, (not counting pictures with budgets over 150 million) since FIELD OF DREAMS, and even then he had to use a character actors help in James Earl Jones. With bombs like WATERWORLD and THE WAR, Costner HAS BEEN blown out. He's nothing in the Hollywood arena. He only got in this film because of Shelton, who worked with him on BULL DURHAM. Bill Cosby, who never can explore much in any character, needed some variety to boost his upcoming ONE FOOT IN THE GRAVE based on the British comedy. They both freeze out here.
JACK is about two parents who have a baby, and find out that he is ageing four times too fast. So, by the time JACK is ten, he'll have the body, and the body organs of a forty-year old. He's tutored by Bill Cosby, who's the only real reason this film is close to surviving. Cosby's very charimatic, surprisingly subtle, and if anything, cool. Of course, who else to play the forty year old that Robin Williams. Williams is in the middle of a great stretch of his career, playing characters that are totally centered around their comic tension, and nothing around sentimentality. JACK fails for this reason. Williams yells and screams, and looks and sounds like a ten year old Jodie Foster in NELL. So, Williams shouldn't be there. He's wasted his talent playing someone with too much well, character, that he ends up losing the character. Was this supposed to be an Oscar attempt for Williams? Was this supposed to bring him to the top? THE BIRDCAGE did that. I expected everything that was in MRS. DOUBTFIRE, THE BIRDCAGE, and JUMANJI combined. That was a high expectation, but I got none of it. Also, Williams doesn't play JACK right, either. Does your ten-year old child crawl into a slide underport and ask her teacher if she wants a gummi-bear? Does he jump up and down, get scary dreams and leap into your bed at night. Jack eventually meets a friend. How nice, Jack gets a friend. Adam Zolodin daftly plays 'the friend' role, with his very ditzy mother played by Fran Drecsher. The movie's real arrogance is that it actually expects us to laugh, cry and get touched. So much for that idea.

 As much as I love to try gussying myself up for the day, there is nothing better in the world then coming home and slipping on clothes that I can move, sleep, play, and even do yoga in if the mood strikes.

 Gorgeous, I tell you. Absolutely gorgeous. As much as I love bright, fun colors, I love that Yogi Clothing mostly consists of beautiful, soothing neutrals that make it perfect for mixing with other workout clothes or even with your regular every day clothes.
Since I’m not only about aesthetics with my clothes, I also have to rave about the quality of their clothing. I was sent the Cowl Back Cardigan, and the Burnout Stripe Racerback Tank and immediately buried my face into them. Both items were SO soft I couldn’t wait to get them on my body but most importantly, I loved that they were supportive enough to get me through a gentle workout yet soft enough to lounge all day in.
Also, both items passed the “chase after toddler, play in the grass test” with flying colors 😉
Since I didn’t get a great picture of me with the front of the cardigan showing (impatient husband behind the camera) here’s a better picture of the top from the web site:
I used this cardigan during one of my favorite warm vinyasa classes. It was the perfect top to throw over the skimpy tank I was wearing so I wouldn’t feel so exposed during my commute, and the top held up during the first half hour of my warm flow class. It held up just fine in the wash and I’ve found that it works perfectly to wear around the house because it’s so comfortable, yet it’s cute enough to run errands in without announcing to the world that I’m wearing yoga clothes.
And the back of the cardigan is a magnet for compliments. SO cute, right!?
As for the racer burnout tank, I was surprised at first at how thin and loose the tank was. I’m used to tight, conforming tanks but loved how the top flowed with me as I ran, did CrossFit, and did yoga. There’s also a built in support bra in the tank which I also wasn’t expecting but discovered I needed, even with the support of a regular sports bra underneath.
See? The tank also works for running after a toddler 😉
And just like the cardigan, I loved that the tank was versatile enough work out in, but to also wear as a regular top for going out. It doesn’t scream “I’m a workout tank” and I dug that. Comfortable AND cute, which is right up my alley.
One last thing about this brand that I love, love, LOVE? They post daily WODs (workouts of the day) that are insanely fun and perfect to do at home. You can check them out here.
LOVE.
Speaking of love…

Comparison Operators
Comparison operators are supported in read requests on numeric, date and string parameters by prefixing the mathematical symbol in the value. This is used in the GET by Query method.
The following operators are supported:
| Operator | Symbol | URL Encoded Symbol | Example | URL Encoded Example |
|---|---|---|---|---|
| Greater than | > | %3E | price > 100 | price=%3E100 |
| Greater than or equal to | >= | %3E%3D | price >= 100 | price=%3E%3D100 |
| Less than | < | %3C | price < 200 | price=%3C200 |
| Less than or equal to | <= | %3C%3D | price <= 200 | price=%3C%3D200 |
Ranges will be supported by specifying the parameter twice, as in:
- price between 100 and 200: price=%3E100&price=%3C200
- price between 100 and 200, inclusive: price=%3E%3D100&price=%3C%3D200
To use a literal < or > as the first character in a parameter value, you must escape it with a URL encoded backslash (%5C). For example, the title=%5C%3Chello
find records with title matching '<hello' (encode as '\<hello').
HTTP Status Code 400 (InvalidRequestException) will returned to the requestor if a parameter is supplied:
- more than once if no comparison operators are present
- more than twice if comparison operators are present
Multiple parameters will be ANDed in the SQL. No ORing will be supported.
For Java API usage, prefix the value in a NameValuePair object with the unencoded operator. Zero or more of these are passed in a List
of parameters when creating a Request object with the Factory.

Connecting PC to bb/rpi3 serial console
How to connect your PC to the serial console on the BeagleBone Black or Raspberry Pi 3. The serial console will allow you to view stdout as well as access the Linux shell.
USB-to-TTL serial cable
A 3.3V FTDI cable is needed to access the output. These cables are available from:
bb – 6pin FTDI cable:
rpi3 – 4pin FTDI cable:
Connecting to Device
bb
The console is configured to output to ttyS0
by default on the bb
.
UART ttyS0
is accessible by the 6 pin header labeled J1 on the Beaglebone Black. Pin 1 on the cable is the black wire and connects to pin 1 on the board, the pin with the white dot next to it.
A 4-pin cable may also be used, with only the GND, RX, and TX header pins connected.
rpi3
By default, the rpi3 will use HDMI for the console. To override and use ttyAMA0
you need to modify your faninit.props
(make sure to run fan studs asm
after):
# Override the controlling terminal (ttyAMA0, tty1, etc.)
tty.console=ttyAMA0
Then the cable can be connected to UART ttyAMA0
via the GND, RXD, and TXD header pins:
Opening a serial session
On macOS and Linux you can use the screen
command to open a serial session to the BBB:
$ screen /dev/tty.usbserial 115200
The actual device name tty.usbserial
will vary. It will typically include usb
somewhere in the name. You can use tab completion to search for the correct device. You can also ls /dev
before and after inserting your USB cable and see what new port shows up.
Power on your BBB and you should now be able to view the stdout as Linux boots and your application is started.
To access the shell, make sure you configure faninit.props
for exit.action
and exit.run
:
exit.action=hang
exit.run=/bin/sh
With these settings, when your Fantom application exits, or you press Ctrl+C
from the console, you will exit to a Linux shell.

The last time he directed a screen adaptation of a best-selling book - Robert James Waller's "The Bridges of Madison County" - Clint Eastwood was working with a slender piece of fiction that required extensive reworking and fleshing-out. With John Berendt's "Midnight In The Garden Of Good and Evil," he faces exactly the opposite dilemma: You need not have read the book to suspect that, even with its generous two-and-a-half hour running time, the movie is a severely abridged version of a longer, richer story. That said, it should also be noted that much of what Eastwood has managed to capture is deliciously decadent, and it's crowned by a smashing performance by the always-mesmerizing Kevin Spacey as Jim Williams, the story's pivotal figure. Even amongst the numerous eccentrics who populate sultry Savannah, Williams is a true character, a suave antiques dealer who's amassed a fortune in the past decade and isn't shy about showing off his money. "I'm nouveau-riche," he tells Town & Country magazine reporter John Kelso (John Cusack), "but then, it's the riche that counts." But in the shadows of his lavish lifestyle lurks a slightly sordid secret life involving young hustlers and drugs. When Williams wraps up one of his sumptuous Christmas parties by shooting a young man he's been arguing with, he simultaneously blows off the door of his closet as well, and the skeletons come tumbling out. New Yorker Kelso, who's in town to cover the annual holiday bash, finds himself perversely enchanted by Williams and the sundry other locals he encounters in the Georgia town. "It's like "Gone With The Wind" on mescaline!" he enthuses to his editor. That proves to be only a slight exaggeration, what with a voodoo priestess, a local lunatic who keeps horseflies tied to his shirt, and a devoted servant who still tends to the ghost of a long-dead dog, all walking the streets.  Each of these people is intriguing, but "Midnight" can't find the time to give each his/her due. Remember those "Want to know more?" buttons that surfaced throughout "Starship Troopers"? You'll be wishing they'd pop up here. Eastwood packs many amusing and eerie moments into "Midnight," elegantly evoking both the wearying heat and the wild heart of Savannah, and treating his cast of eccentrics with a certain degree of dignity. By this time though, he ought to have learned that nepotism doesn't pay: Casting his son Kyle in "Honkytonk Man" handicapped that film, and putting daughter Alison in "Midnight" is a similar mistake. While by no means a disaster along the lines of Sofia Coppola in "The Godfather III," Ms. Eastwood doesn't demonstrate much allure as the siren who puts the make on Kelso; the part seems to cry out for an Ashley Judd or a Mira Sorvino instead.
