Last week I got the chance to face an interview for the position of a Softwre Engineer, (Intern) and I thought I would share the details. Hope this would be helpful for anyone who is looking for some tips before going to an interview.
So let’s start with the CV. When you’re preparing the CV don’t include each and every achievement, experience and project you did. CV is mainly a marketing document. Do some research on the company you’re applying, and customize your CV so that it only includes relevant data about yourself, which might come in handy if you get to work in that particular company. (E.g. If a company is heavily using a particular framework, emphasis your experience and the projects you did using that framework.)
If you’re adding a project that you did on the CV, you’re expected to answer any question regarding that project. So if you decide to include a group project, you should know all the aspects of it. When the interviewer asks a question about the client-server communication aspect of a particular project, you shouldn’t say that “I only did the database part and I have no idea about the communication part”. It would only display your ignorance and negligence.
And keep in mind to add your interest in the CV too. Don’t add a particular topic just because it is the current trend. Instead add topics which are relevant and you’re passionate about.
Before going to the interview, polish your knowledge on certain topics like OOP principles, databases, design patterns, algorithms and languages like Java. You can Google and find out what kind of questions are asked frequently in interviews from above topics. And also don’t forget to research and get the gist of the technologies which are mostly used by that particular company you’re applying.
When going for the interview, wear something simple, but professional. And get to the place at least 15 minutes early. Always be polite, smile, pay your full attention to the interviewer and do not lie under any circumstance. If you don’t know the answer to a question, be humble enough to say that you don’t know. When answering the questions don’t rush, take your time and explain yourself clearly. If you don’t understand the question, politely ask to explain it a bit more instead of answering without comprehending the question. Keep in mind that having good communication skills can play a key role in an interview. You might be a really intelligent person, but poor communication skills might let you down. So if you think that there is room for improvements, better get started working on that right away.
Last but not least, and interview is a chance to market yourself and to convince the other party that you’re the one they’re looking for and you’d be a valuable asset for the company. And if you failed to do that analyze what you did wrong, learn your lessons and be more prepared for the next opportunity.


Barricade allows apps to get responses to API requests by intercepting them using an OkHttp Network Interceptor. The responses are fetched from local assets based on the configuration.
Barricade also supports multiple responses per request, unlike other local server implementations and presents the user with a UI for modifying which response to return for a request at runtime. It also provides an option to change the response and latency of the API call programatically
The source code of Barricade, and the sample app is available on GitHub.
compile 'com.mutualmobile:barricade:(insert latest version)'
annotationProcessor 'com.mutualmobile:barricade-compiler:(insert latest version)'
Barricade supports Android 4.1+
Barricade
is the runtime class which is used to initialize and configure the library
dynamically.
BarricadeConfig
is the class which is generated at compile time based on the
@Barricade annotations and data provided inside it.
BarricadeActivity
is an activity class which provides a UI to select the default
response for each API endpoint.
Below are the steps to configure Barricade in an Android application -
Install Barricade in the onCreate()
method of your Application
class.
@Override
public void onCreate() {
super.onCreate();
new Barricade.Builder(this, new BarricadeConfig()).enableShakeToStart(this).install();
...
}
Note: Setting enableShakeToStart to true starts BarricadeActivity when device is shaked
twice.
Add your API response files to assets/barricade/<endpoint_name>
for
different types of responses (success, invalid, error etc).
In the Retrofit service API interface, annotate the methods with @Barricade. The @Barricade
annotation accepts 2 parameters:
@Response
annotations corresponding to various
responses barricade can return
@GET("/users/{user}/repos")
@Barricade(endpoint = "repos", responses = {
@Response(fileName = "get_repos_success", isDefault = true),
@Response(fileName = "get_repos_error", statusCode = 500)
}) Single<ReposResponse> getUserRepositories(@Path("user") String userId);
...
Each @Response
annotation corresponds to a unique response for the given
endpoint. It takes 4 parameters:
assets/barricade/endpoint/
Add BarricadeInterceptor
to OkHttpClient
OkHttpClient okHttpClient =
new OkHttpClient.Builder().addInterceptor(new BarricadeInterceptor())
...
.build();
Barricade can be enabled or disabled at runtime.
To enable - Barricade.getInstance().setEnabled(true);
To disable - Barricade.getInstance().setEnabled(false);
Change response for endpoints
Barricade allows changing the response time and the default response for an endpoint at runtime.
If enableShakeToStart was set to true during Barricade initialization, the following process can used to configure Barricade -
You can also change the above settings programmatically which can be helpful for testing -
Barricade.getInstance()
.setDelay(100)
.setResponse(BarricadeConfig.Endpoints.REPOS, BarricadeConfig.Responses.Repos.GetReposSuccess);
Note: Changes made using setDelay and setResponse are persisted in SharedPreferences.
If you would like to contribute code you can do so through GitHub by forking the repository and sending a pull request.
When submitting code, please make every effort to follow existing conventions and style in order to keep the code as readable as possible.

LM- and NT-hashes are ways Windows stores passwords. NT is confusingly also known as NTLM. Can be cracked to gain password, or used to pass-the-hash.
NTLMv1/v2 are challenge response protocols used for authentication in Windows environments. These use the NT-hash in the algorithm, which means it can be used to recover the password through Brute Force/Dictionary attacks. They can also be used in a relay attack, see byt3bl33d3r’s article [1].
If you’re still confused, I would recommend reading the Wikipedia articles. I do hope this intro clears up the confusing language and can somehow help you.

The client authentication is carried out according to the policy on the prevention of money laundering on the basis of the law of the 4th European Union anti-money laundering Directive (AMLD IL) on June 5, 2015 with the observance of the rules of combating money laundering in the UK http://www.legislation.gov.uk/all?title=Money%20Laundering
The KYC rule for assessing potential risks
One of the "soft" international benchmarking is the rule KYC – Know Your Client, an established translation of which into Russian language is formulated as "Know your customer!". In accordance with the practice of this principle it would be better to translate into Russian as "the Rules for selection of customers." Its essence boils down to the need to provide a potential customer of the financial organization of documents containing regulated information about his identity.
What documentation identificeret personality in the system of the KYC
A set of standardized documents for legal
entities and individuals and its composition is determined by
the nature of the procedure. For example, to open a Bank account you will need along with the filled
application form submit:
- a notarized copy of important (with photo and signature) pages of the passport;
- proof of residency (it can be a certified translation of the passport of a resident with a photo, signature and place of residence or, for example, a certified copy of the accounts for the provided utilities);
- recommendation from a Bank where the applicant already has an account, or a letter of recommendation or a lawyer or a chartered accountant the accompanying activities (it should describe the status of the relationship).
How does KYC
The system performs several functions. On the
one hand, KYC financial structure gives an opportunity to
protect their interests:
- it certifies the identity of the client;
- allows security to determine the degree of risk of customer involvement in illegal activities (a priori it is considered that such a risk is subject to each individual client);
- allows you to manage your own risk to install the filter, regulating the type and number of transactions for a specific customer;
- allows you to monitor unusual client transactions and, if necessary, to initiate their investigation.
On the other hand, in most cases, KYC plays into the hands and to the client. They provided truthful information will help the Bank employee to give him such an account that will meet real needs – whether they support the business or asset protection. Broker of a stock exchange, knowing the financial situation of his client and the specificity of its activity, will give him the most suitable investment advice, and financial Advisor will select the best solution for asset management.
Thus, the policy customer identification KYC is a kind of protective mechanism and for clients and accompanying them to activities of business entities. It clearly structures the admissibility of relevant financial transactions and protects both parties from possible penalties.

I asked for button objects that do what I want. Somebody else did all the programming. The buttons are components that can be added with minimum effort.
This is similar to going to a hardware store to get components for your home improvement project. Most of the parts you need already exist. You just assemble them.
In Java programming, you can get the GUI components you want merely by asking for them. Most of the work has already been done and is contained in the Swing package. Swing contains windows, frames, buttons, menus and other components.
A user interacts with a GUI application by causing events. The application must respond to events in the order they arrive. The picture shows this. Each time the user interacts with a component, an event is sent to the application. Different events are sent to different parts of the application. The application has to work correctly no matter what the user does. (Usually an application ignores events that are not relevant to its purpose.)


Files CCore/inc/MakeFileName.h CCore/src/MakeFileName.cpp
MakeFileName is a simple Helper Type. It is derived from the MakeString<MaxPathLen> and may contain some file path. It should be used to build such path from a directory path and a file name.
class MakeFileName : public MakeString<MaxPathLen>
{
public:
MakeFileName();
MakeFileName(StrLen dir_name,StrLen file_name);
MakeFileName(StrLen dir_name,StrLen file_name,StrLen auto_ext);
StrLen operator () (StrLen dir_name,StrLen file_name);
StrLen operator () (StrLen dir_name,StrLen file_name,StrLen auto_ext);
};
Default constructor creates a null object.
MakeFileName(StrLen dir_name,StrLen file_name) creates the object with the full path, combined from the directory path and the file name. dir_name may ends with a slash.
MakeFileName(StrLen dir_name,StrLen file_name,StrLen auto_ext) adds the given auto-extension, if the file name has no one.
operator () resets the object and does the same job as the correspondent constructor. It returns the result as the StrLen.
An exception is thrown in case of overflow.

There are two different colors of nodes in the graph. The orange node indicates that the node is a central node, a blue node indicates that the node is not.
When hovering over the graph using a cursor, multiple pop-ups can be seen. These pop-ups occur when hovering over a node or a link. When hovering over a node, the node's ID (provided from the Facebook API) will be shown. When hovering over a link, the link's value will be displayed. This value represents the number of likes/comments (depending on which type of graph is selected) between the two nodes.
With regards to what the "Central Node Value" is measured with, it is measured according to degree, not distance.
The reset button resets the page, in case something is not loading. Also very helpful when coding and updating the page. The clear button just clears the current graph that is displayed. Really has no use as selecting a new graph will automatically clear the old graph by default.

Computes (ST(1) ∗ log2 (ST(0))), stores the result in resister ST(1), and pops the FPU register stack. The source operand in ST(0) must be a non-zero positive number.
The following table shows the results obtained when taking the log of various classes of numbers, assuming that neither overflow nor underflow occurs.
ST(0)
| − ∞ | − F | ±0 + ∞****− ∞ | +0<+F<+1 + ∞+ F + 0 − 0 − F − ∞ | + 1 −0 −0 +0 +0 | + F > + 1 − ∞− F − 0 + 0 + F + ∞ | + ∞− ∞− ∞+∞+∞ | NaN NaN NaN NaN NaN NaN NaN |
| NaN | NaN | NaN | NaN | NaN | NaN | NaN | NaN |
Notes: F Means finite floating-point value. * Indicates floating-point invalid-operation (#IA) exception. ** Indicates floating-point zero-divide (#Z) exception.
If the divide-by-zero exception is masked and register ST(0) contains ±0, the instruction returns ∞ with a sign that is the opposite of the sign of the source operand in register ST(1).
The FYL2X instruction is designed with a built-in multiplication to optimize the calculation of logarithms with an arbitrary positive base (b):
logbx ← (log2b)-1 ∗ log2x
This instruction’s operation is the same in non-64-bit modes and 64-bit mode.
ST(1) ← ST(1) ∗ log2ST(0); PopRegisterStack;
| C1 | Set to 0 if stack underflow occurred. Set if result was rounded up; cleared otherwise. |
| C0, C2, C3 | Undefined. |
| #IS | Stack underflow occurred. |
| #IA | Either operand is an SNaN or unsupported format. Source operand in register ST(0) is a negative finite value (not -0). |
| #Z | Source operand in register ST(0) is ±0. |
| #D | Source operand is a denormal value. |
| #U | Result is too small for destination format. |

I was born in the year of the Iran-Contra Scandal. I don't know if that means anything, but it's kind of interesting. I was also born in the same hospital as the guy who played Geordi La Forge.
Busy, busy, busy.
I moved from Texas to Chicago in 2010 with the love of my life. She's pretty awesome.
I love Netflix-binging, writing, and trying out fancy whiskies. I can name more members of the Justice League than presidents. I'll forever be angry that I don't have superpowers.
But I do have coding–specifically, I work in: Ruby, HTML5, CSS, and JavaScript. I'm a big fan of Rails and Sinatra (The framework, not the lounge singer). You can see some of my work at my GitHub.
I'm currently open for work--shoot me a tweet (@jordythedev) or hit me up on Google Plus.

Quigley: ‘Hearsay Can Be Much Better Evidence than Direct’ Evidence
Democrat Rep. Mike Quigley (D-IL) defended “hearsay” evidence during the first public hearing of the impeachment inquiry on Wednesday.
by Kristina WongDuring the hearing, witnesses Bill Taylor and George Kent, both senior State Department officials, could not present direct evidence of President Trump trying to leverage military assistance or a White House visit in exchange for Ukraine launching investigations into Joe Biden and his son — only what they heard from other officials.
But Quigley tried to defend the use of “hearsay” as evidence, claiming it could be “much better” than direct evidence.
“Hearsay can be much better evidence than direct evidence,” he said.
That declaration prompted mocking on social media, including from the president’s son Donald Trump Jr.
“Can you believe this insanity? ‘Heresay [sic] can be much better evidence than DIRECT EVIDENCE’ according to Democrat Mike Quigley. Are you fricken kidding me? 3rd and 4th party info better than hearing it yourself?” Trump Jr. tweeted.
In his opening statement at the hearing, House Intelligence Committee Ranking Member Devin Nunes (R-CA) recalled how Democrats “falsely” claimed there was “more than circumstantial evidence” of collusion between Trump and the Russians.
In one notable moment from the hearing, Rep. Jim Jordan (R-OH) mocked witnesses’ hearsay evidence as more complicated than “prayer chains.”
“’Ambassador Taylor recalls that Mr. Morrison told Ambassador Taylor that I told Mr. Morrison that I conveyed this message to Mr. Yermak on September 1, 2019, in connection with Vice President Pence’s meeting to Warsaw and a meeting with President Zelensky,'” Jordan said, reading from U.S. Ambassador to the European Union Gordon Sondland’s testimony.
He said to Taylor, “We got six people having four conversations in one sentence, and you just told me this is where you got your clear understanding.”
“I’ve seen church prayer chains that are easier to understand than this,” he added.

An extension of {{ this.title }} may be formalised as a profile. A profile is a {{ this.title }} which extends the default specification towards more specific needs.
A profile is declared on the profile
property. For the default {{ this.title }} descriptor, this SHOULD
be present with a value of default
, but if not, the absence of a profile
is equivalent to setting "profile": "default"
.
Custom profiles MUST
have a profile
property, where the value is a unique identifier for that profile. This unique identifier can be in one of two forms. It can be an id
from the official Data Package Schema Registry, or, a URI that points directly to a JSON Schema that can be used to validate the profile.
As part of the {{ bag('site', 'name') }} project, we publish a number of {{ this.title }} profiles. See those profiles below.

module Cryptodbm:sig
..end
This library provides an encrypted layer on top of the Dbm and Cryptokit packages. The improvements over Dbm are:
As a quick example, the following uncrypted bindings (key => data):
"john-doe" => "age 36" "some secret" => "The cake is a lie." "Motto" => "For relaxing times, make it Suntory time"
are stored as follows in the encrypted file (with variations depending on the password, and other parameters):
[S~j....O.Q..tk^.2] => [...F...).Hsl..tB] [...y;....~.:.6V.2] => [....I...JR..w.E9..G..q=...K....b] [..'.C...F.x.3K.y2] => [1.)9q..M...et.b.] [S.....5 Y....8..2] => [.D........2..u...q.......}Z.b..z.zo.}.l3l.....>.]<EMAIL_ADDRESS>=> [hb..2.._B....Y?0....|.....tM....] [K.#i.7j..H.ZZ.^.2] => [..z....,........]
Including several subtables in the same database file avoids having to deal with multiple files to store related information, and also prevents information leak through the number and sizes of a set of database files.
This library was primarily designed to store encrypted exam files on a university server. A common layout consists in several subtables encrypted with a global password, as well as an uncrypted subtable containing (public) meta-information.
Install and compile
Install using opam: opam install cryptodbm
Compile with ocamlbuild by adding the following to your _tags file:
<**/*> : package(cryptodbm)
Performance
I have not benchmarked this library. Keep in mind that every access (reading or writing a binding) requires to encrypt the key, and encrypt the data (when writing) or decrypt the data (when reading). Don't be pessimistic, though: it seems all right for non critical applications.
Also, there is only a global key-index for the whole table, no key-index for individual subtables. As a consequence, subtable iterators actually iterate over the whole table index (selecting only the expected subtable indexes).
A few technical details
When a database file is encrypted,

Barrick agrees sale of super pit as it begins $1.5bn asset disposal
by Edward ThicknesseBarrick Gold, one of the world’s largest mining corporations, has begun the disposal of $1.5bn (£1.2bn) of its non-core assets by agreeing to sell its 50 per cent stake in Australia’s Kalgoorlie mine for $750m.
The so-called “Super Pit”, located in the renowned golden mile region of Western Australia, will be bought by Saracen Mineral Holdings, an ASX-listed company which already owns two other gold mines in the area.
Read more: Gold miner Acacia’s shareholders overwhelmingly approve Barrick takeover
The Kalgoorlie mine produced 490,000 ounces of gold in the last financial year, making it one of Australia’s largest.
Newmont Goldcorp, the world’s leading gold company, will retain its 50 per cent stake in the joint venture.
Mark Bristow, Barrick chief executive officer, commented on the sale: “The sale of our non-operating interest in KCGM represents the first step in our plan to realize in excess of $1.5 billion from the disposal of non-core assets by the end of next year.
“While this iconic gold mine has been a valuable contributor to Barrick over the years, the asset does not fit with our strategy of operating mines that we own. The sale allows us to further focus our portfolio on core operations.”
Saracen managing director Raleigh Finlayson said that the acquisition would support the company’s strategic goals:
“This transaction will enhance our business across a variety of key financial and operational metrics and provide our shareholders with exposure to a third high quality Western Australian gold asset.
“The transaction establishes Saracen as a leading gold miner with anticipated production in excess of 600koz per annum exclusively from the Goldfields region of Western Australia for many years to come.”
Read more: Odey hedge fund backs Barrick Gold takeover of Acacia Holdings
In September the shareholders of Tanzanian miner Acacia Holdings forced through a motion to sell the business to Barrick, in an attempt to end a two-year standoff with the Tanzanian government.
It means that Acacia, which was spun off from Barrick in 2010, will come back under the watchful eye of the Canadian giant.

Help & Manual
Robot settings
no available settings, to set password go to Router Password page. Please remember your password, the robot is secure at the moment there is no easy way to recover lost passwords. You can also decide not to set a password and keep logging in without one, however in this case you will not have ssh access. Default password is: robot
Camera Settings
Changing camera settings will be available in future updates. You can also change these settings in /etc/config/mjpg-streamer
Note: quality 80 will start the camera in yuv mode. This is the only way ro make some cheap cameras work. If you have a webcam that supports on board compression you will not need yuv mode and you can use considerably higher resolution and framerate as it won't use the on board cpu.
default values.
device = 0
resolution = "320x240"
fps = "10"
quality = "80"
port = "8080"
Motor calibration
By default the motors do not use encoder feedback (open loop)
You can change this by editing /etc/config/robot where the motor numbers are percentages.
Example: if your robot is bearing left on a straight the right side is faster so assuming your right side is plugged into motor channel 1 you want to reduce motor channel 1. Try 90, then continue tweeking until it is correct. Robot will need reboot to reload this setting.
default values:
motor1 = 100 %
motor2 = 100 %
motor3 = 100 %
motor4 = 100 %
Sensor calibration
No available settings, future updates will let you add analog sensors and calibrate them.
Arm add-on settings
No available settings, Future updates will let you enable arm plugin.
Storage Devices
Your USB flash memory will be mounted automatically. At this point only the first one (the one that you plug in first) will be used for storing images.
For advanced setup: Mount Points
Connect to existing network
In future updates there will be a way to connect to existing networks easily.
In the current implementation the network resets every reboot, this is recommended as there is no easy way to recover mistakes in wireless connection.
You can keep an new wireless setting during multiple reboots by changing /etc/config/robot reset parameter to the number of reboots.
If you change it to -1 the wireless won't be reset anymore. Only do this when you are confident your new setting is working or if you have a serial programming lead.
Update Firmware
To update firmware please use router's interface: Flash operations

Just want to know if somebody knows this game :D
This is the Menu-Music and it's just awesome!

If anybody wants to play the game, or need help with installing it on Win7 here:
http://www.youtube.com/watch?v=bcdhQdJHq8Q
This way is totally legal and free, the game was adware on gamenewspapers often enough though.
When you want to use the Trackeditor, you need an .dll-file and put it in the editor Folder
This right there:
http://de.dll-files.com/d3drm.dll.html
: DO NOT PRESS ANY ORANGE BUTTON JUST THIS ONE BELOW IN THE PIC!
Picture:
dll.PNG
Then you just need to unzip the File.
Have FUN while playing! :D


In West Philadelphia, born and raised, on the playground is where I spent most of my days:
- Chilling out
- Maxing
- Relaxing, all cool
I was shooting some b-ball outside of the school when a couple of guys — they were up to no good — started making trouble in my neighborhood.
I got in one little fight and my mom got scared. She said,
“You'll move in with your
Auntie and your Uncle in Bel-Air.”

r/TrollXChromosomes, a subreddit within reddit.com, has over 180,000 subscribers on reddit, not to mention lurkers who read the subreddit without creating an account. r/TrollXChromosomes developed as an offshoot of another subreddit dedicated to female perspectives (r/TwoXChromosomes), and was originally devoted to sharing and commenting on rage-comics and memes centering female perspectives. Five years after its inception, it has developed an identity of its own and has truly become a Third Place (Oldenburg, 1999) for women on the Internet.
Via participant observation and semi-structured interviews of the community members, we sought to understand why women (and men) participate in this online community, the main themes of content shared and discussed of the community, and to gain a deeper insight into how the community works. Through a combination of participant observation and semi-structured interviews of r/TrollXChromosomes members, we discovered why members are drawn to the community, along with emergent themes defining the site’s experience - such as support, authenticity and humor.
Customer Driven Innovation (CDI) is a repeatable method for creating great ideas and products. It is based on a rigorous understanding of your customers and their needs. Developed from the principles of Design Thinking by the Stanford d.School, similar variations are in use at companies across the world, such as PayPal, eBay, Google, IDEO, Lego, and many more.
The goal of the stakeholder-user study was to understand the broader sales cycle, capture the pain points around current demo request and delivery processes, and gauge requirements for the upcoming demo. Semi-structured interviews were conducted with 18 stakeholders involved at various stages of the sales process (Solutions Consultant, Sales Managers, Channel Development Managers, Project Managers). Each interview session lasted for approx. 30 minutes during which there were questions around their prevalent processes, their challenges and pain points and their perceptions and aspirations for the newer product version and the corresponding version of the sales demo. Interviews were conducted over phone which were recorded and analyzed.

[telegram] <mark> Hi, thread. Two of us are trialling BarterDEX, but are finding it very hard going. Will we be able to get advice here?
[telegram] <Acura360> At youtube there are many tutorials videos or you can test HyperDex (re @mark: Hi, thread. Two of us are trialling BarterDEX, but are finding it very hard going. Will we be able to get advice here?)

[telegram] <mark> Hey, Acura. Have been extensively over the Youtube material, and not found it helpful
[telegram] <Acura360> Oh ok (re @mark: Hey, Acura. Have been extensively over the Youtube material, and not found it helpful)
[telegram] <jamescheng25> join komodo on discord ttps://discord.gg/kS3vx9J
[telegram] <jamescheng25> and ask in support channel, you might get a better luck
[telegram] <mark> Thank you, James. That's a great idea
[telegram] <jamescheng25> actually currently slack is better, but the team is in the process of migrating to discord
(edited)
[telegram] <mark> One of my communities recently did the same thing
[telegram] <jamescheng25> yes, discord is so much cooler
[telegram] <jamescheng25> btw what kind of problem do you have with barterdex?
[telegram] <jamescheng25> I've used it a few times
[telegram] <mark> Several related problems, James. No matter how I prepare the UTXOs, I have a low success rate with trades, and I presently have several trades market 'Finished' in purple, but they are clearly hung
[telegram] <Acura360> Which Barterdex Version do you use (re @mark: Several related problems, James. No matter how I prepare the UTXOs, I have a low success rate with trades, and I presently have several trades market 'Finished' in purple, but they are clearly hung)
[telegram] <mark> 1.0.6rc
[telegram] <jamescheng25> 1.0.7 rc is the latest one
[telegram] <Acura360> NEW Barterdex Release 1.07. is out !!
https://github.com/KomodoPlatform/BarterDEX/releases/tag/v1.0.7-rc
Changelog
-New Coins: SPK, CRDS, ATB, HXX, VRSC, MLM, XSN, DCN, ELF, GPN, SRN, LRC, DROP, SANC, UCASH, RVT
-Updated Marketmaker binaries (re @mark: 1.0.6rc)
BarterDEX: Decentralised Exchange and Cryptocurrency Market
[telegram] <jamescheng25> so it is finished but the coin is not in your wallet?
[telegram] <jamescheng25> did you use the block explorer and check? sometime barterdex takes a bit to show the balance
(edited)
[telegram] <mark> Acura, will try latest B-DEX right now. James, have been trying to figure out the trade status data. Been trying to reconcile balances shown on the site with the status of trades
[telegram] <Acura360> (re @mark: Acura, will try latest B-DEX right now. James, have been trying to figure out the trade status data. Been trying to reconcile balances shown on the site with the status of trades)
[telegram] <mark> Will come back tomorrow. Don't wanna seem hostile, but just exhausted with wading through Youtubes and calculating UTXOs but still not being able to reliably trade. (My favourite crypto is listed on B-DEX, so we have an interest in figuring it all out!)
[telegram] <jamescheng25> ok, sure take your time. It definitely takes some learning curve ;)
[telegram] <jamescheng25> Hyperdex is more user friendly but not supporting as many coins as B-dex yet
[telegram] <mark> Well, such an admission goes a long way to helping me maintain my patience — and really, my mob has a big interest in DEXes overall
[telegram] <jamescheng25> nice, which coin if i may?
[telegram] <mark> I'm gonna go out on a limb here: I'd like to see smaller-scale stuff that both works and has fine instructional material, than many-biggee-listings projects that are unnecessarily hard. (re @jamescheng25: Hyperdex is more user friendly but not supporting as many coins as B-dex yet)
[telegram] <jamescheng25> the next iteration of marketmaker should make trading on barterdex and hyperdex much smoother.
[telegram] <mark> I really am looking forward to HyperDEX.
[telegram] <jamescheng25> currently both DEXes depend on marketmaker version 1 , i hopefully marketmaker 2.0 will make everything easier
(edited)
[telegram] <mark> And FYI, James, my mob is actually a trust-alliance of crypto geeks rather than members of one coin's community: a number of us are working over a number of DEXes
(edited)
[telegram] <Matt> Thats not real?? (re @stayfrosty1: )
[telegram] <jamescheng25> very cool , Mark. I am also a big believer in DEXes
(edited)
[telegram] <jamescheng25> maybe once you get it working, you can learn how to be a Liquidity Provider - making money while providing liquidity for your favorite coins
[telegram] <mark> https://distribuyed.github.io/index/ — although only hobbyists, James, we aren't newcomers. We do stuff with energy; but as you appreciate . . . there's so much stuff! So, we found a list of two hundred DEXes. Put on the coffee pot
A comprehensive list of decentralized exchanges (DEX) of cryptocurrencies, tokens, derivatives and futures, and their protocols.
[telegram] <mark> This is exactly the sort of enterprise that might attract us in the long term (re @jamescheng25: maybe once you get it working, you can learn how to be a Liquidity Provider - making money while providing liquidity for your favorite coins)
[telegram] <mark> James, could I 'bookmark' you for future questions?
[telegram] <jamescheng25> yes, sure , I am not the expert, but I know where to direct you to ;)
[telegram] <mark> Off to the garden, me. Thanks for your energy.


//! API bits for the Secure Computing facility in the Linux kernel, which allows
//! processes to restrict access to the system call API.
//!
//! Seccomp started life with a single "strict" mode, which only allowed calls
//! to read(2), write(2), _exit(2) and sigreturn(2). It turns out that this
//! isn't that useful for general-purpose applications, and so a mode that
//! utilizes user-supplied filters mode was added.
//!
//! Seccomp filters are classic BPF programs, which means that all the
//! information under `std.x.net.bpf` applies here as well. Conceptually, a
//! seccomp program is attached to the kernel and is executed on each syscall.
//! The "packet" being validated is the `data` structure, and the verdict is an
//! action that the kernel performs on the calling process. The actions are
//! variations on a "pass" or "fail" result, where a pass allows the syscall to
//! continue and a fail blocks the syscall and returns some sort of error value.
//! See the full list of actions under ::RET for more information. Finally, only
//! word-sized, absolute loads (`ld [k]`) are supported to read from the `data`
//! structure.
//!
//! There are some issues with the filter API that have traditionally made
//! writing them a pain:
//!
//! 1. Each CPU architecture supported by Linux has its own unique ABI and
//! syscall API. It is not guaranteed that the syscall numbers and arguments
//! are the same across architectures, or that they're even implemted. Thus,
//! filters cannot be assumed to be portable without consulting documentation
//! like syscalls(2) and testing on target hardware. This also requires
//! checking the value of `data.arch` to make sure that a filter was compiled
//! for the correct architecture.
//! 2. Many syscalls take an `unsigned long` or `size_t` argument, the size of
//! which is dependant on the ABI. Since BPF programs execute in a 32-bit
//! machine, validation of 64-bit arguments necessitates two load-and-compare
//! instructions for the upper and lower words.
//! 3. A further wrinkle to the above is endianess. Unlike network packets,
//! syscall data shares the endianess of the target machine. A filter
//! compiled on a little-endian machine will not work on a big-endian one,
//! and vice-versa. For example: Checking the upper 32-bits of `data.arg1`
//! requires a load at `@offsetOf(data, "arg1") + 4` on big-endian systems
//! and `@offsetOf(data, "arg1")` on little-endian systems. Endian-portable
//! filters require adjusting these offsets at compile time, similar to how
//! e.g. OpenSSH does[1].
//! 4. Syscalls with userspace implementations via the vDSO cannot be traced or
//! filtered. The vDSO can be disabled or just ignored, which must be taken
//! into account when writing filters.
//! 5. Software libraries - especially dynamically loaded ones - tend to use
//! more of the syscall API over time, thus filters must evolve with them.
//! Static filters can result in reduced or even broken functionality when
//! calling newer code from these libraries. This is known to happen with
//! critical libraries like glibc[2].
//!
//! Some of these issues can be mitigated with help from Zig and the standard
//! library. Since the target CPU is known at compile time, the proper syscall
//! numbers are mixed into the `os` namespace under `std.os.SYS (see the code
//! for `arch_bits` in `os/linux.zig`). Referencing an unimplemented syscall
//! would be a compile error. Endian offsets can also be defined in a similar
//! manner to the OpenSSH example:
//!
//! ```zig
//! const offset = if (native_endian == .Little) struct {
//! pub const low = 0;
//! pub const high = @sizeOf(u32);
//! } else struct {
//! pub const low = @sizeOf(u32);
//! pub const high = 0;
//! };
//! ```
//!
//! Unfortunately, there is no easy solution for issue 5. The most reliable
//! strategy is to keep testing; test newer Zig versions, different libcs,
//! different distros, and design your filter to accomidate all of them.
//! Alternatively, you could inject a filter at runtime. Since filters are
