I had just eaten some fried chicken. I went to the store and bought a 4 ounce bottle of VICKS with just DMX in it. I drank the whole thing. Got home about 30 minutes later, drank another bottle of VICKS, but this one had pseudophedrine in it as well. After about 3 hours, I was feeling stoned and drunk, but I could still be coherent, and walk normally. I was getting pissed, because usually it doesn't take 3 hours. I decided to drink another half bottle of VICKS with pseudophedrine. Bad move. Turns out, the food had delayed the reaction.
At this time, I began to watch the movie snatch. My parents were gone at this time, and as I watched the movie, I began to consider the actors characters in a video game.  I lost track of time, and thought my parents had been gone for about 6 hours. It had been about two. I called them, told them I was lonely, and that they should come home. I was beginning to slur my words. They didn't notice though.
My dad is an ER doctor. He sees quite a few people tripping, so I had decided to stay in my room that night and watch my colored lights and listen to Floyd. Good idea. I staggered upstairs to my room as soon as I heard the car pull in. I stayed in there for about 30 minutes, but I started overheating and got really thirsty, so I went downstairs to get a drink of water.
My parents were standing there in the kitchen talking about something.  I couldn't really tell where my legs were, so sometimes I would stomp my feet down, sometimes putting them down very lightly - I fell once, which I think tipped them off. I got up, and opened the cupboard and got a glass. My parents are watching me still. I filled it up with water, and tried to drink some.  I turned to stomp/stagger up to my room, when my mom says, STOP. At this point I was tripping so bad it didn't register I was going to be possibly caught. She says, why are your eyes so dilated? Jesus Christ! Look at his eyes! My dad looks, and says, yep. They are dilated. Are you high?
I said no quite vehemently. I actually yelled it, so I pretty much said 'Yes, I can't control the volume of my voice!' That's what it amounted to. Anyway, they started a ruthless interrogation, which dragged on for hours, actually about 5 minutes. During this time, my answers were complete gibberish, if I managed to get the whole sentence out before my mind trailed off into the trippy, trippy, DMX high. One question was, why are you so thirsty? My answer:
Hime notch hirsty I gust..... then I looked around until they told me to go to my room.
The next morning, I received a drug test. I was positive for Amphetamines and PCP. My dad informed me that he had found 3 bottles of cough syrup in the trash, and that DMX and pseudoephedrine can cause false positives. I have to get another drug test in about a week.

On this course I've learned how to implement float menu to switch pages, header, footer, divisions on page to fit the text, embedded multimedia (local and from YouTube) and pictures, zoom in on pictures, pictures legends and forms. In addition to that, there are too many CSS3 configurations on header, texts, links, etc. The video below shows the main implementations made on the site.

Oh, no, not another package format!
This is probably the first thought many people might have when hearing about xPacks. There are enough package formats and package managers, why would we need yet another one?
Well, first, the xPacks project does not introduce a new package format, but uses exactly the same format as npm, and xPacks can be stored in the same repositories, public or private.
And xpm, the project manager, is built on top of npm, the very popular JavaScript package manager, extending it with new language neutral features, so things are not that scary as they seemed initially.
I’m perfectly happy with my development environment, why would I bother with xPacks?
The current development environments are indeed great, and rolling distributions like Arch and Homebrew do a tremendous job in keeping the systems up-to-date, but not rarely the latest and greatest available versions break older applications and various complex processes, like build scripts, that depend on older versions.
The xPacks dependency mechanism is intended to solve exactly this problem, by providing a simple and uniform solution of installing different versions of the same package in different folders, and managing dependencies.
Nix also provides reproducible builds, plus lots of packages, why bother with xPacks?
Nix is a great project, and takes a very strict path in controlling the versions, down to the individual library. However, by design, it uses links to files, which are not available (or are not reliable) on Windows, thus Nix is currently available only on GNU/Linux and macOS. Plus that the Nix language requires quite some efforts to master.
Why could npm not be used as-is and why exactly was it necessary to invent xpm?
Because each package manager implements a strategy for managing dependencies. npm/yarn/pnpm all implement various strategies specific to ECMAScript dependencies.
Unfortunately these strategies do not work for other languages, like C/C++; plus that it would be very difficult and require ugly hacks to accommodate development dependencies to binary archives (for tools like compilers).
Why bother to manage versions when auto-configure can sort out the differences?
The traditional way of dealing with different versions and variations between systems is to add a complex auto-configure mechanism that is able to detect which tools/components are present, which versions, and with this input do its best to parametrise the process (for example a project build), to accommodate for all these differences.
This approach started with GNU configure, and today use even more complex solutions, like CMake or meson scripts.
Well, instead of permanently wondering how to make use of the new versions, and making the auto-configure scripts more and more complex with every day, why not allow the application to ask for the exact versions that are known to be compatible, and let an automated tool handle the dependencies?
The xPacks project manager can do just this, bring in the project exactly the versions needed, thus making the auto-configure step superfluous.
But what are xPacks?
In brief, xPacks are general purpose multi-version software packages.
By multi-version it is understood not only that packages can have multiple versions, but they can be installed in parallel, allowing each project to have its own set of dependencies.
Based on the installed content, there are currently two types of xPacks: source and binary:
- source xPacks are packages that install source files, generally libraries used by the project.
- binary xPacks are packages that install standalone executables/binary files, generally tools used during the build process, like toolchains, builders, etc; standalone means they are self-contained and do not depend on other shared libraries or tools.
Where does the name come from?
xPack, pronounced ɛks-pæk, can be understood as Universal Package, or Any Type Package, and tries to suggest that, when compared to npm packages (which are basically JavaScript packages), xPacks are more general, and not linked/limited to a specific programming language.
Initially the x came from eXtended, so eXtended Packages can be another choice.
What exactly is an xPack?
The full definition is:
package.json
file, defining at least
the package name
, the package version
, and an xpack
property,
even empty.Given the direct inheritance from npm packages, a canonical definition might be:
xpack
property defined in package.json
.xpack.binaries
and xpack.bin
properties defined in
package.json
.Package formats
As for npm, a package is any of the following:
- A folder containing a
package.json
file. - A gzipped tarball containing (1).
- A URL that resolves to (2).
- A
<name>@<version>
that is published on the registry with (3). - A
<name>@<tag>
that points to (4). - A
<name>
that has alatest
tag satisfying (5). - A
git
url that, when cloned, results in (1).
How to convert my project to an xPack?
Create a package.json
file in the root folder of your project with at
least the following definitions:
{
"name": "my-awesome-project",
"version": "1.0.0",
"xpack": {}
}
package.json
has a few more
fields, please read
Creating a package.json file
for details.A more automated method is to use xpm init
:
% mkdir xyz && cd xyz
% xpm init --verbose
xPack manager - create an xPack, empty or from a template

Why would I convert my project to an xPack?
The top reasons are:
- to automate dependencies management
- to automate path management for dependent tools
- to manage multi-configuration builds
These are both simple and complicated things. To better understand them, please continue to read how binary and source xPacks work.
How do binary xPacks work?
Let’s assume that ‘my-awesome-project’ needs the arm-none-eabi-gcc
toolchain to build,
and not any version but a specific one, like 12.2.1
; it also needs
the latest CMake, ninja and the liquidjs npm module.
For this, in the project folder, issue the following command, which will install the required tools in a global xPacks store location, and add links to them.
% xpm install<EMAIL_ADDRESS>@xpack-dev-tools/cmake@latest @xpack-dev-tools/ninja-build@latest --verbose

{

"xpack": {
"minimumXpmRequired": "0.14.8",

}
^
used in the version field is
a npm/semver convention that means compatible, in other words the
highest version that does not change the major number, if available.^
means exact version.
Use this syntax for binary xPacks with longer version numbers,
which generally do not abide by the semver requirements.The result is the tools being downloaded and installed in the global
xPack store (a folder in user’s home) and links from the project
to that folders created in the local xpacks
folder, with links to
individual programs added in xpacks/.bin
(or .cmd
stubs on Windows).
Similarly for liquidjs, which is a Node.js CLI npm module, after
installing the module, npm will
add a folder node_modules/.bin
where links to the executables
will be created (or .cmd
stubs on Windows).

When later running actions like xpm run build
, the PATH
is automatically
adjusted to xpacks/.bin:node_modules/.bin:$PATH
, so the exact versions
of the tools required in the dependencies list will be preferred over any
existing tools with the same names that might be present in the PATH
.
Binary xPacks are probably huge, aren’t they?
Not at all; on the contrary, binary xPacks are very small, just a
package.json
file, since they include only the URLs where the binaries
are actually stored (for example links to GitHub Releases), not the
binaries themselves.
How do source xPacks work?
Even simpler. Let’s assume that the ‘xyz project’ also needs the
µOS++ trace support, which is available as the source xPack
@micro-os-plus/diag-trace
.
% xpm install @micro-os-plus/diag-trace --verbose
xPack manager - install package(s)

Example
A real example is an embedded project that lists as dependencies two source xPacks, one Node module and three binary xPacks:
{
"name": "h1b",
"version": "1.0.0",
"description": "An xPack with a blinky application running on HiFive1",
"...": "...",
"devDependencies": {
"xmake": "^0.3.9"

"@gnu-mcu-eclipse/openocd": "^0.10.0-7.1",
"@gnu-mcu-eclipse/windows-build-tools": "^2.10.1"
}
}
}
The two source xPacks actually pull in six source xPacks, and the binary
xPacks contribute a lot of links to xpacks/.bin

THE "HA-AF" A FACE.
JAMES BERRYMAN said, "Fa-ather took a house doun to Lelant, whear we lived for a bra' bit. Very often after I ben in bed, our ould cat wud tear up, coover its ars like a ma-aged thing, jump uppon the bed, and dig her ould hed under the clothes, as if she wud git doun to bottom, and jest after, a man's face, with a light round un, wud cum in; kwas ha-af a face like, and it wud stop at the bottom of the bed. I 'ye sen it many times; and fa-ather, though he didn't say nothin', was glad enough to leave the place. I was tould that the house belonged to an ould man, and that two rich gentlemen, brothers, who lived close by, wanted the place, and put on law, and got the place from the poor ould man. When they war goin' to turn un out, the poor fellow stopped and looked round crying, and then fell down in a fit, was put to bed, and died in the house; and 'twas he, they said, that used to come back."

6 Conclusion
The goal of this project was to use Natural Language Processing to classify fake news. To do so, a dataset web scraped from PolitiFact was used. The text was cleaned, the vocabulary reduced, and features were extracted. Then, seven different machine learning models were fit using these features. The two most basic algorithms (Naive Bayes and basic logistic regression) performed the worst with accuracies of 60% and 62% respectively. The other five models performed relatively equally: they all had accuracies around 70%.
 With a topic such as fake news, which has already hurt much of the American public’s perception of the government, any misclassification is exacerbated. A 70% accurate fake news classifier used in practice has poor implications in terms of improving the public’s trust in what is fake and what is not. Thus, far more work is needed in order to create a reliable fake news classifier. Luckily, there are clear areas in which this work can be improved upon due to the limitations laid out in the next section.
6.1 Limitations
Among other things, the raw PolitiFact dataset used in this project contains the original PolitiFact URL, the PolitiFact truth rating, the claim of the article being assessed, and the URL and text from the article where the claim came from. The original idea of this project was to use the original article text (along with the PolitiFact truth rating) to train a fake news classifier. However, each article’s text is not necessarily making the claim that PolitiFact is grading in each entry since each PolitiFact grade is based on the claim that an article is reporting on, and not the article itself.
For example, if an article is reporting on a claim that is false—and casting the same doubt on that claim that PolitiFact does with their truth rating of “False”—then the article text itself is not necessarily false (even though the claim it’s reporting on is). This means that the target of “False” would not be aligned with the article text. There’s no way to check whether or not an article’s text is casting doubt on a claim rather than presenting the same claim that PolitiFact is fact-checking without manually going through each article. Since this is infeasible, the project switched from using the original article text in feature extraction to the claim being graded by PolitiFact. This meant that duplicate PolitiFact entries could be removed from the dataset (as they all have the same claim and truth level).
Additionally, this project initially tried to classify all six different PolitiFact truth levels. In the end, only the PolitiFact claims rated as “True” (\(1\)) or “Pants on Fire!” (\(6\)) were used. This was done as a way to simplify the many models fit in the project as well as to increase model performance. A process where all ratings from 1-3 were classified as “True” and all ratings from 4-6 were classified as “False” was attempted, but this resulted in worse model performance. The reason for this is likely because article claims are inherently very short pieces of text and because determining the difference between a “Half-True” and “Mostly False” article is a very difficult task when only looking at an article’s claim by itself.
The many models fit in this project suffered at the expense of the amount of data available. After dealing with the limitations mentioned above, only \(1911\) rows were left in the dataset. This is not nearly enough data in the context of NLP, especially when using deep learning algorithms. In standard NLP deep learning problems, datasets have somewhere on the order of tens of thousands of observations (instead of \(1911\) in the case of this project).25
6.2 Future Work
The largest areas for future work in this project are to collect more data and to fine tune the deep learning methods used. As mentioned in Section 6.1, the amount of data used in this project was not on the same scale as other NLP deep learning models. The collection of more—and higher quality data—is paramount in increasing the accuracy of a fake news classifier. Additionally, there is much work to be done to improve the performance of the models used in this project. A limited amount of hyperparameter tuning was done in this project, as performing robust hyperparameter tuning for seven different models is beyond the scope of this project. In particular, there is much work to be done in fine-tuning the deep learning models due to their inherent “black box”26 nature.
“How to Build a Neural Network With Keras Using the IMDB Dataset” (n.d.)↩
In machine learning, “black box” refers to the idea that “data goes in to a model, decisions come out, but the processes between input and output are opaque.” “Black Box” (n.d.)↩

Basic mouse operations
There are four basic mouse operations: Touch, Pick-up, Carry, Place-down
- Touch an object (the square root in this example)
- Pick up its copy (left mouse click)
- Carry it wherever you want
- Touch where you want to place it down (the insertion point between 14 and z in this example)
- Place-down the carried object by left mouse click
Touching aim the mouse pointer at an object and it will highlight blue. By pointing at right spots you can touch whole expressions and even whole equations...
- To touch more than one object (multi-touch), hold down the Shift key (or mouse button) and move the pointer over the equation.
- You can also touch insertion points. Touched insertion point is represented by blue or green line (as in the step 4. of the example above).
Picking-up and carrying once you touched something, mouse-click to pick up a copy of it. The copy can then be carried away with your mouse.
- The mouse arrow becomes black when you carry anything.
- You can always throw away whatever you carry by pressing the Esc key, or by right-click at empty document area.
Note: Instead of copy, you can cut touched object by holding the mouse button down for a longer time (a long-click) while you performing the pick-up action. The effect is the same as if you used Ctrl+X (cut).
Placing-down you can place down the carried object by mouse click. There are several distinguished ways to place-down:
- Over other object(s) touch object(s) while you carry something and then mouse-click. The touched object(s) will be replaced
- At an insertion point touch an insertion point while you carry something and then mouse-click. The carried objects are inserted.
- At empty document area point the mouse button at empty area while you carry something and mouse-click. A new object is created.
The Insertion Point
The Insertion point is a place (usually between two elements in an equation) where you can insert new elements. When touched, the insertion point is visible as a blue or green line. Two things can happen if you left-mouse-click at an insertion point:
- if you carried something, this will be inserted here
- if you didnt carry anything, the keyboard entry mode will start

New York Giants' Janoris Jenkins skewered for missed tackle on Dallas Cowboys tight end
by Ryan GaydosNew York Giants cornerback Janoris Jenkins was roasted on social media Monday during a game against the Dallas Cowboys.
The one particular play Jenkins was catching heat for his effort, or lack thereof, trying to tackle Cowboys tight end Blake Jarwin as he rumbled into the end zone. Jarwin caught a pass from quarterback Dak Prescott and broke a few tackles to score.
SPORTS BROADCASTER KEVIN HARLAN GIVES DRAMATIC PLAY-BY-PLAY OF BLACK CAT'S METLIFE STADIUM INVASION
Jenkins appeared to be frozen in time and stuck his arm out as Jarwin zipped by him.
The veteran defensive back was immediately skewered on Twitter by fans and media for the seeming lack of effort.
BLACK CAT HALTS GIANTS-COWBOYS MONDAY NIGHT FOOTBALL GAME, LEAVING VIEWERS TRANSFIXED
The score came with under a minute to play in the first half. Dallas would get the ball one more time and finish the half with a 52-yard Brett Maher field goal to obtain the lead, 13-12.
The Cowboys wouldn’t lose the lead again. Dallas outscored the Giants 24-6 in the second half and went on to win the game, 37-18.
Dallas improved to 5-3 on the season with a slight edge over the Philadelphia Eagles in the NFC East division. The Giants fell to 2-7 on the year.

The Index is Key
Storing and Organizing Data in Ruby
February 22, 2015
This week was pretty exciting for me. We got an intro to Ruby. I learned that basically everything is an object…. And in order for these objects to function, we need to call methods on them. Because Ruby can hold so much data, in variables, classes, methods, etc, it is important to keep the data in some sort of order. This is where arrays and hashes come in.
Arrays and hashes are both classes (a larger type of object in ruby), which store other objects (strings, numbers, variables, other arrays and hashes, you name it, arrays and hashes can store them). While arrays and hashes are very similar, they have some key differences. So how do we know when to use which?
First let’s talk about arrays. An array is an ordered list that stores objects. The easiest way to identify (and actually create an array), is by using square brackets “[ ]”. Let’s say we want to teach someone the proper symbols to use for math methods. We can create an array to store these symbol. We can name our array ‘math array’ and then set it equal to empty square brackets:
math_array = []
That’s it. That’s an array. It’s that simple. Obviously this array is empty, but we can go ahead and fill it whenever we’d like. We would call the math array, and set it equal to the square brackets, filled with the objects we choose. For our math array, we’ll fill it with math operators:
math_array = [‘+’, ‘-’, ‘*’, ‘/’, ‘%’, ‘**’]
So now that we have our array set, we can access all of those operators by calling math_array. When we call our array, it will just print out a list of those operators. But what if we don’t want the whole list? The objects in an array are integer-indexed, starting at 0. This means that in order to access the first value, we would use index 0, the second value would be index 1, third would be index 2, and so on. When you call the index on the array, it outputs the value in that position. Since our array only has six values, let’s go ahead and call them all. On the left you’ll see how to call the objects in the array using the index number, and on the right you will see the output, or value:
math_array[0] => +
math_array[1] => -
math_array[2] => *
math_array[3] => /
math_array[4] => %
math_array[5] => **
Pretty cool, right? We’ve received the operators as outputs. But what if we can’t remember what the operators, or symbols stand for?
That’s where a hash may be more appropriate. A hash is an ordered list that stores objects… But wait?! Isn’t that an array? Yes! A hash is a type of array (but let’s not get ahead of ourselves yet.) A hash is easily identified by curly brackets “{ }.” Like an array, a hash can be created by setting its name equal to empty curly brackets, like so:
math_hash = {}
And like an array, that’s it. That’s a hash. So how do we add and access the actual information? Here lies the biggest difference between a hash and array. Hashes use key/value pairs. This means instead of using an index number, to call our objects, we will use a key. For the sake of this example, we will keep our values, the same as the values in the array above:
math_hash = {
“Add” => “+”,
“Subtract” => “-”,
“Multiply” => “*”,
“Divide” => “/”,
“Modulo” => “%”,
“Exponent” => “**”
}
So there we have our math_hash. By calling the keys on math_hash, we’re asking for the value as our output. This is similar to calling the index number on our array. Check it out below:
math_hash["Add"]=> +
math_hash["Subtract"] => -
math_hash["Multiply"] => *
math_hash["Divide"]=> /
math_hash["Modulo"]=> %
math_hash["Exponent"] => **
It’s a lot easier to understand when to use an array vs. when to use a hash, when you can actually visualize what they are. As you can see, a hash serves almost like a dictionary, or a key. And an array works as an index, kind of in reverse, you look up the index number, and it tells you what you would find there.
Next week we will be going over calling methods on our arrays and hashes. This will make up the bulk of some of our projects. Come back next week for more info on Ruby, and methods!
Thanks for stopping by!

Discussion about Komodo scalability. Komodo has demonstrated 20,000 TPS.
100 messages
Before 05-Dec-19 12:00 AM
blackjok3r17-Jul-18 08:26 AM
However if you just want data to say a blockchain can run at full block capacity, you could just point to BTC at the end of last year... every block was full for months straight.
I dont see a need to prove what has already been proven.
Mylo17-Jul-18 08:29 AM
OK fair point.
What has been the largest scale test tx/s to date?
blackjok3r17-Jul-18 08:30 AM
The 1024 chain test.
but they were 100 pyamnt TX's so the 20,000 number is far lower than theortically possible.
The 256 chain test, to test kubernetes should eclipse that number easily... theoretical maximum is ~37k tx/s.
If we need higher than that we can use 512 chains to double it.
Either size will give us the data we need.
Mylo17-Jul-18 08:50 AM
It's pretty much processing bytes of tx data across a decentralized chain cluster. Correct?
100 chains ~= 200MB/min
1000 chains = ~=2000MB/min
10000 chains = ~=20000MB/min
I want to build a template/HOWTO so others can take our work and implement their own test.
Possible now? Or some doc gaps to fill ?
blackjok3r17-Jul-18 09:21 AM
for a single payment TX.... which is 1 vin to 2 vouts (your payment and the change returned to the first address) you can fit 8859 TX's into a 2MB block.
For a 100 payment TX, (1 vin to 101 vouts) you can fit 557 TX into a block. Anything inbwteeen should follow a fixed ratio, you can check this by creating some TX's and seeing how big the raw hex generated is.
Each chain can process on average 2MB per minute,
The transaction size also would work the other way, ie, combining 100 vins to 1 vout, to "join" the UTXO's back together.
With this data you can do math to work out how many chains is required to achieve any required amount and size of transactions.
My repo's would need some updating and some more docs for others to start at square 1, with no chains, and generate the JSON with the chain cluster parameters. But its not really that hard, with some updates to my scipts and docs, you can generate any number of chains in a cluster and all required scripts automatically to launch a notary node network to notarize them to KMD.
It took me about 2H from zero notary network to a network of 4, and min sigs for a notarization of 2.
In real world, I think min sigs would need to be more than 2 and notary nodes would need to be more than 4, however the compute resource required for these is pretty small. Biggest requirement is RAM and network bandwidth.(edited)
Mylo17-Jul-18 09:49 AM
This is great, thanks heaps
So, with your engineers hat on - in case it wasn't , a "real world" use case would have multiple vin:vout combos and there'd be many more addresses.
blackjok3r17-Jul-18 09:49 AM
Yes.
Which is why I think we should describe it as maximum payments, however even then, the size of the transactions will still vary and the amount of payments in a block will also vary. It totally depends on use case. Designing your cluster to run at capacity is also not clever, likey you would use 50-100% more chains than you 'need'.
Mylo17-Jul-18 09:54 AM
Pretty much bytes processing throughput, with a handful of variables that us clever humans use to measure these concepts as payments and transactions.
Noted re: deployment rationale.

Result = tech will be on site tommorow afternoon
I have my suspicions that connection issues are due to amplified "metadata" retention, and the tech is actually an ASIO spook, but as long as the c*nt sorts out my connection I'll scrub down the filth afterwards

past that. got my paperwork in order. Dont tend to make threats without being ready to execute them. If ASIO tech fixes it, no need to esculate, but sad thing is they dont do much without the threat.
GatewayBOT18-Jul-18 10:19 PM
[matrix] <mylo5ha5:matrix.org> ASIS are who you wanna watch out for - make sure your tech doesn't have the secret handshake :P
smk762 - dracocanis ominator19-Jul-18 07:54 AM
... they must know I'm on to them... tech didnt show up. I noticed they reported 'no fault', and blamed internal wiring, but never showed up to confirm by actually testing the internal wiring.

blackjok3r20-Jul-18 01:02 AM
@patchkez When you have some free time, whats the status on the kubernetes stuff? I noticed yesterday there are 3 small 8 core instances left running on the KomodoPlatform account, doesn't seem like they cost a huge amount, just wondering if you got them working or just forgot to shut them down.
My Internet changes over (to FTTN) on the 27th of July, so I would say if we dont get the next stage up and running by then, it would be best to leave the 256 chain test until next month when @smk762 - dracocanis ominator 2 is back from holidays and hopefully both our Internet connections are up and running. This also leaves plenty of time for marketing to work out their end.
Of course we need to test a small 24 chain test on kubernetes first to make sure your YAML etc is correct and everything is working with my recent changes. I have ported the dockerfile and all scripts so its the same for all chains, and everything is set in the docker-compose.yml so set-up should be trivial in that regard.

@blackjok3r I killed those instances yesterday, I do not need them now. I am still trying to fix problem with kubectl not able communicate to Kubernetes cluster. I tried to recreate cluster several times, modified kube config but still when communicating with cluster, it is asking for username and password. Just FYI I followed this guide https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html. Heptio authenticator is configured correctly, it can use AWS credentials. I will open support case today and ask for help.

All good. We had an issue yesterday too, trying to use API keys to access a DynamoDB, it always said DB does not exist, despite me being able to fill it with data no problem using the same Keys, maybe these things are somehow related?
Hopefully support gets back to you in a reasonable time frame.

@Mylo some nice bio petri dish loooking visualisations there. Lots of vertices, even on 10 min blocks at 3-4tx/s
Once the scale tests hit 1 million, I might have a crack at geovisualising notarisations of kmd and asset chains
Acura22-Jul-18 06:31 AM
Can anybody give me a link to a source of the 45k TPS Test ? It is for a webmaster that compare‘s Projects with there TPS Results
That is an interesting read. That definition of sharding sounds like taking the long route to the destination (the destination being scalability)
What are the key differences between KOMODO’s approach to scalability and ‘sharding’?
Komodo is the world's only blockchain platform to offer both security and limitless, on-demand blockchain scalability to every project on the platform.

Awesome thanks for sharing the info Mylo. Those links gave me some clarification.
Is the scaling test still scheduled for the end of the month?
Mylo25-Jul-18 07:31 AM
Waiting. Combo of things to wait on. Internet upgrades (we have some shitty internet here in AU), holidays, AWS support ticket re: kubernetes.
We are able to use google cloud but because of all the waiting involved, at least waiting for next week when internet upgrades should have been completed and hopefully AWS has looked at the support request.

blackjok3r25-Jul-18 07:33 AM
We are not 100% sure when the next test will be, @smk762 - dracocanis ominator has internet back so we are going to run some simulations tonight and make 100% sure everything is still working as expected. I will contact @patchkez and find out the status of the AWS once he is available. I really hope we can get a 24 chain test launched on kubernetes before the end of this week, which gives me next week to get everyhting ready for the 1 million TX test while smk is on holdiays.(edited)

Have fun with that. It took months to even be able launch EC2 instances.
Seriously though, we are all good to wait, hopefully they help you out.
64 chains for the above. Simulated data exceeded 1.2mil at 8192 chains. Just waiting for aws to sort things out and we should be able to replicate that running live

Hermes26-Jul-18 06:06 PM
Hi guys
Question from a Telegram User:
45,000 TPS means you can handle 45,000 transactions per second.
transaction means one smartcontract.
However, Komodo's block generation cycle is one minute.
Does that mean that 45,000 X 60 = 2,700,000 tx/min is possible every minute?
Or is it possible to contract every second?
Mylo26-Jul-18 11:14 PM
45k tx/s but if you waiting for a confirmation, then yes 2,700,000 tx/min (with testing due soon to 60,000,000 tx/min 1st confirmation) & per contract if required when it get released, because contracts run in their own blockchain and implement cross-blockchain interoperability as per the crypto-conditions standard published by the IETF (internet engineering task force), that manage internet standards like IP addresses, DNS, email protocols etc.

the -ac_cc=3 needs to be changed to -ac_cc=1001 or higher
blackjok3r29-Jul-18 11:15 AM
Ok... We finally found the problem with skipped blocks in the website live display today. Using AWS has is drawbacks, but the advantage of not needing a webserver that can handle 8000+ connections per minute outweights them, once we figured out what was happening that is.
Also what branch of komodo should I be using now, it was on momo but I changed it to dev when CC were merged in. Is this still the one I need to use? @jl777c
jl777c29-Jul-18 11:16 AM
dev branch will work with -ac_cc=1001
blackjok3r29-Jul-18 11:17 AM
No problem, I will update coins.json with new values.
Just waiting on AWS support to help @patchkez with kubernetes deployment, also looking at out account limits, there is no way we can launch 8192vcpu's at this stage, so someone needs to talk to them about that.(edited)
I am very close to launching a fully notarized test though. Could do mayb 256 chains, with first 64 notarized in a couple of weeks. Depends on what marketing wants, I would rather use that test to run kubernetes and kill two birds with one stone, after we confirm its working with a very small cluster.
blackjok3r29-Jul-18 11:50 AM
changed everything to ac_cc=1001 and pushed to repos.
Mylo29-Jul-18 11:59 AM
if you run 64 chains and all 64 are notarized, that's about 6k tx/s isn't it? i can use that info for dApp develop HOWTO documentation. 64 chains notarized @ 100KMD per year is 6k KMD. @300KMD it's 19k KMD.
6k tx of the 1 payment per tx
blackjok3r29-Jul-18 12:17 PM
that depends.
The first time I tried it, i had it set a freq.2
and it burned through all myt UTXO's in an hour
Been a fair while though, cant quite remember exactly how much it was.
Mylo29-Jul-18 12:24 PM
ok - well if you want a hand doing 64, i'm keen to get some docs for it.
can budget for all of it
then execute on said budget
those sort of figures will be handy too
blackjok3r29-Jul-18 12:36 PM
no worries. I already did it once... I have a repo that builds all nessary scripts, just need t add pubkeys and IP's to it and your away.
I think there was 1 or 2 steps missing from my notes.

Memory storage/state for a single AddressSpace.
Class for setting and getting memory values within a space The basic API is to get/set arrays of byte values via offset within the space. Helper functions getValue and setValue easily retrieve/store integers of various sizes from memory, using the endianness encoding specified by the space. Accesses through the public interface, are automatically broken down into word accesses, through the private insert/find methods, and page accesses through getPage/setPage. So these are the virtual methods that need to be overridden in the derived classes.
| MemoryBank::MemoryBank | ( | AddrSpace * | spc, |
| int4 | ws, | ||
| int4 | ps | ||
| ) |
Generic constructor for a memory bank.
A MemoryBank must be associated with a specific address space, have a preferred or natural wordsize and a natural pagesize. Both the wordsize and pagesize must be a power of 2.
| spc | is the associated address space |
| ws | is the number of bytes in the preferred wordsize |
| ps | is the number of bytes in a page |
|
static |
Decode bytes to value.
This is a static convenience routine for decoding a value from a sequence of bytes depending on the desired endianness
| ptr | is the pointer to the bytes to decode |
| size | is the number of bytes |
| bigendian | is true if the bytes are encoded in big endian form |
|
static |
Encode value to bytes.
This is a static convenience routine for encoding bytes from a given value, depending on the desired endianness
| ptr | is a pointer to the location to write the encoded bytes |
| val | is the value to be encoded |
| size | is the number of bytes to encode |
| bigendian | is true if a big endian encoding is desired |
| void MemoryBank::getChunk | ( | uintb | offset, |
| int4 | size, | ||
| uint1 * | res | ||
| ) | const |
Retrieve an arbitrary sequence of bytes.
This is the most general method for reading a sequence of bytes from the memory bank. There is no restriction on the offset or the number of bytes to read, except that the range must be contained in the address space.
| offset | is the start of the byte range to read |
| size | is the number of bytes to read |
| res | is a pointer to where the retrieved bytes should be stored |
|
protectedvirtual |
Retrieve data from a memory page.
This routine only retrieves data from a single page in the memory bank. Bytes need not be retrieved from the exact start of a page, but all bytes must come from one page. A page is a fixed number of bytes, and the address of a page is always aligned based on that number of bytes. This routine may be overridden for a page based implementation of the MemoryBank. The default implementation retrieves the page as aligned words using the find method.
| addr | is the aligned offset of the desired page |
| res | is a pointer to where fetched data should be written |
| skip | is the offset into the page to get the bytes from |
| size | is the number of bytes to retrieve |
Reimplemented in MemoryPageOverlay, and MemoryImage.
|
inline |
Get the number of bytes in a page for this memory bank.
A MemoryBank is instantiated with a natural page size. Requests for large chunks of data may be broken down into units of this size.
|
inline |
Get the address space associated with this memory bank.
A MemoryBank is a contiguous sequence of bytes associated with a particular address space.
| uintb MemoryBank::getValue | ( | uintb | offset, |
| int4 | size | ||
| ) | const |
Retrieve the value encoded in a (small) range of bytes.
This routine gets the value from a range of bytes at an arbitrary address. It takes into account the endianness of the underlying space when decoding the value. The value is constructed by making one or more aligned word queries, using the find method. The desired value may span multiple words and is reconstructed properly.
| offset | is the start of the byte range encoding the value |
| size | is the number of bytes in the range |
|
inline |
Get the number of bytes in a word for this memory bank.
A MemoryBank is instantiated with a natural word size. Requests for arbitrary byte ranges may be broken down into units of this size.
| void MemoryBank::setChunk | ( | uintb | offset, |
| int4 | size, | ||
| const uint1 * | val | ||
| ) |
Set values of an arbitrary sequence of bytes.
This the most general method for writing a sequence of bytes into the memory bank. There is no restriction on the offset to write to or the number of bytes to be written, except that the range must be contained in the address space.
| offset | is the start of the byte range to be written |
| size | is the number of bytes to write |
| val | is a pointer to the sequence of bytes to be written into the bank |
|
protectedvirtual |
Write data into a memory page.
This routine writes data only to a single page of the memory bank. Bytes need not be written to the exact start of the page, but all bytes must be written to only one page when using this routine. A page is a fixed number of bytes, and the address of a page is always aligned based on this size. This routine may be overridden for a page based implementation of the MemoryBank. The default implementation writes the page as a sequence of aligned words, using the insert method.
| addr | is the aligned offset of the desired page |
| val | is a pointer to the bytes to be written into the page |
| skip | is the offset into the page where bytes will be written |
| size | is the number of bytes to be written |
Reimplemented in MemoryPageOverlay.
| void MemoryBank::setValue | ( | uintb | offset, |
| int4 | size, | ||
| uintb | val | ||
| ) |
Set the value of a (small) range of bytes.
This routine is used to set a single value in the memory bank at an arbitrary address It takes into account the endianness of the associated address space when encoding the value as bytes in the bank. The value is broken up into aligned pieces of wordsize and the actual write is performed with the insert routine. If only parts of aligned words are written to, then the remaining parts are filled in with the original value, via the find routine.
| offset | is the start of the byte range to write |
| size | is the number of bytes in the range to write |
| val | is the value to be written |
