Axis
Extends:
The Axis class is responsible for drawing the axis onto the canvas and setting the new origin used for the canvas. All objects displayed will be referenced to the position of the axis. Therefore, by changing its position the origin is also displaced.

--- title: AES Random Number Generator layout: post tags: [crypto] uuid: df183700-1207-311d-619a-c9c97bebe7a7 ---
I came across the Ultra High Security Password Generator the other day, which uses a very high quality pseudo-random number generator to generate passwords and keys. The idea is not to use the full 63 characters as a password, but rather a contiguous subset, such as the first 8 characters.
The website is served securely, so no middle man can sniff at it. If you trust the maintainer not to store the generated numbers somewhere, which he claims not to be doing, then you can use it as a nice password generation service. If you are nervous about matching password possibilities to your IP, then grab a batch through the Tor network.
In terms of brute-force attacks, each letter from hexadecimal characters is worth 4 bits, from random printable ASCII characters is worth about 6.6 bits, and alpha-numeric is worth about 6 bits.
If you go with the set of printable ASCII characters, 6 to 8 characters (39 to 52 bits) should be good enough for an account password, where an attacker must guess through an attempt-limiting authentication system. 8 to 12 characters (53 to 79 bits) should be plenty for a passphrase used as an encryption key, where an attacker can brute force passphrase attempts at his leisure.
I wouldn't use this website for any serious encryption, though. If he is logging generated passwords, he will have a nice short list of possible passphrases to try against your encryption. So don't use it for your GPG passphrase. Generate those locally.
This is where the purpose of my post comes in! He describes the pseudo-random number generator he uses to generate the random numbers at the top of the page. It's the AES block cipher in cipher-block chaining (CBC) mode encrypting a 128-bit counter. A picture (well, diagram) is worth a thousand words,
Note that the diagram is actually being explicit about CBC mode, so the AES cipher in the diagram is in electronic codebook (ECB) mode. I missed this myself when initially interpreting the diagram and writing my implementation. Here is the same diagram with the AES cipher already in CBC mode,
I don't know if he designed this himself or not. I implemented it in C to study it a bit. You can grab it here with git (or follow the link and get a snapshot),
git clone git://github.com/skeeto/aesrng.git
To build it, you will need libgcrypt installed (with headers).
Here is about 100 megabytes analyzed with ent, a pseudo-random number sequence test program.
Entropy = 7.999998 bits per byte. Optimum compression would reduce the size of this 100000000 byte file by 0 percent. Chi square distribution for 100000000 samples is 275.58, and randomly would exceed this value 25.00 percent of the times. Arithmetic mean value of data bytes is 127.5095 (127.5 = random). Monte Carlo value for Pi is 3.141182766 (error 0.01 percent). Serial correlation coefficient is 0.000005 (totally uncorrelated = 0.0).
Wow! These results are great! This is exactly what you would see if
you ran 100 megabytes of /dev/random
, a true
random number generator, through ent. It is also pretty fast,
generating that 100 megabytes on my laptop in about 7 seconds. That's
much faster than Linux's /dev/urandom
(over a minute
here), whose ent results aren't quite as good, either.
Note: Before you go using this somewhere important you should make sure this PRNG has been peer reviewed and carefully studied by professionals with cryptanalysis. It may have fundamentals flaws. I only found this on a website somewhere!
Still, that's a pretty damn cool pseudo-random number generator.
The generator is only useful if you want to generate more than 512 bits worth of numbers, because it takes 512 bits of randomly generated numbers to initialize the generator. If you want to generate a single password if the same strength, give this a shot,
head -c 50 /dev/random | tr -cd "A-Za-z0-9@#\!\$%^&*()_+=-~;,.<>/[]{}|?:'\\\`" && echo
It uses a true random number generator and selects from 94 printable ASCII characters (space not included).

Guidance
How system leaders can help schools improve how they spend their pupil premium budget.
A pupil premium review looks at how a school is spending its pupil premium funding. As a reviewer, you will work with the school to improve the school’s pupil premium strategy so that they spend the funding on approaches shown to be effective in improving the achievement of disadvantaged pupils.
You will carry out a focused review of their current provision and work with the school to put in place an improved strategy, including planned spend, on specific evidence-based interventions.
A guide to effective pupil premium reviews has been developed by the Teaching Schools Council in partnership with teaching schools, the Department for Education and the Education Endowment Foundation.
You should be able to provide evidence of having improved the achievement of disadvantaged pupils, in schools that you have either led or supported closely. Evidence of this can include:
If you would like to become a pupil premium reviewer, email<EMAIL_ADDRESS>.
In the email, please provide a short description of your experience of having improved the achievement of disadvantaged pupils.
‘Champion’ teaching schools have been appointed in each region to provide training and support to pupil premium reviewers. A list of the schools can be found on the Teaching Schools Council website.
A review will be recommended following an Ofsted section 5 inspection that finds that a school:
Schools do not need to wait for an Ofsted inspection recommendation to seek a review. Any school can arrange a review at any time to improve the work they do with their pupil premium budget.
We offer an online directory listing independent experts who are designated system leaders and have a track record in raising the achievement of disadvantaged pupils.
The output will be a written document signed off by you. A copy is sent to the school’s headteacher and chair of governors. Ofsted may review this at future monitoring visits.
After the review, the school should have an improved strategy for raising the achievement of disadvantaged pupils and spending their pupil premium funding, informed by the recommendations in the review. You should write the strategy with the school, and you should have an opportunity to comment on a draft of the strategy. The strategy should be agreed by the school’s governing body or trustees. If they would like you to provide any further support, you can arrange this with them directly. This would be considered a deployment.
In addition to the pupil premium review, a review of governance may also be recommended.
You are not required to do a specific number of reviews.
Schools are responsible for paying for their pupil premium review. There is no set cost for a review and it is up to you to negotiate an appropriate amount. As a guide, day rates should reflect pay and expenses for a senior leader or headteacher, including the costs incurred by their school to release them. A typical day rate for a system leader is around £300-£500. The review will probably take between 2 and 4 working days.
If you have any questions about system leaders, please email<EMAIL_ADDRESS>or contact our help desk.

Dear Sir, Naturally this letter will come to you as a surprise since we do not know each other, please permit me however to introduce myself. I am Didan Kimati, a staff of the Ministry of Finance and Economic planning here in Ghana. At the risk of boasting, I wish you to understand that I am a top personal aid to the Minister and therefore, I am privy to several pieces of information. This aside, I am the secretary to the Contract payment committee. Subsequent upon the recent debt relief granted by the G8 Nations to the Republic of Ghana, the Government under the leadership of his Excellency, President John A. Kufour, has decided to pay off all the accumulated back-log of contract debts owed to both local and foreign contractors. However, some of these contract debts span from the regime of his excellency, Osagyefo Dr. Kwame Nkrumah down to the PNDC government of Flt. Lt. John J. Rawlings and to his NDC government days even to the first tenure of President Kufour. To this effect, some of the contractors can no longer be traced as they have tried severally to receive their payment success. Obviously, some may have died. The proposal: I wish to implore you to come in as our partner to claim the sum of $745 Million United States Dollars which is payment due some contractors who built the Akosombo Hydro-electric dam. The contract was divided in 3 phases. The civil contractors, the water engineers and the electrical engineering companies. I understand that you may not know anything about this subject and you may not even be conversant with the procedure for building a dam. But do not worry as we have covered all the bases. All we need to do is apply for an initial payment of $475 Million United States Dollars for the first phase of the contract. As soon as this is successfully transferred to your account, we will apply for the other balance. You do not need to worry about the original contractors. This has already been taken care of. We removed some of the files when we took them for review. All we have to do is replace them with your company details. As soon as this is done, we shall approve your file for immediate payment. Once again, do not worry about this, it will be approved. At this juncture, I wish to point out that the funds are currently deposited at the Swiss National Bank and I am currently in Geneva where I have held series of meetings with the bank officials at the Swiss National Bank who have assured me that once the neccessary documentation are in place the funds will be directly wired to the designated account. Of course we will give them something for their troubles. While I am here you may reach me on telephone number<PHONE_NUMBER>355 We have estimated that it will take between 10 and 14 working days to complete this project. Should you wish to participate, please contact me. You may be worried about the legitimacy of this, you may also be worried about if it were found out. The answer is do not worry, everything has been carefully thought out and planned. Should you have any questions of whatever nature, please do not hesitate to ask me. By the way, you may be worried as well, that this is a scam. There is no need for you to worry. We do sincerely hope to work this out with you. As regards what's in it for you, we propose a sharing ratio of 60:40. 60% for us and 40% for you. If you have any problems with this, please note that we are open to negotiations so long as they are reasonable. Do accept our heart felt good wishes as I look forward to your response. Until I hear from you, I am with very kind regards, Didan Kimati

- For videos that require a rotation, this is the clockwise
rotation in degrees that the application should apply for the video for it to be rendered
in the correct orientation. This value will always be zero on API levels 21 and above,
since the renderer will apply all necessary rotations internally. On earlier API levels
this is not possible. Applications that use TextureView
can apply the rotation by
calling TextureView.setTransform(android.graphics.Matrix)
. Applications that do not expect to encounter
rotated videos can safely ignore this parameter.pixelWidthHeightRatio
- The width to height ratio of each pixel. For the normal case of
square pixels this will be equal to 1.0. Different values are indicative of anamorphic

What is the difference between <div> and <frame>?
Answer:
<div> tag is the division or section of the HTML document. You can define the specific format to the elements defined in the div tag in CSS so when you would like to apply the same style to that particular element then you just need to call that div tag.
<frame> tag is specifically used with the HTML5. It has the particular frame/set to the frameset.
<div> tag is just for the grouping in the styling while <frame> used to sub divide the page.

I won’t make the mistake of ‘third term’ -Buhari
by Kamarudeen OgundeleKamarudeen Ogundele, Abuja
President Muhammadu Buhari has said that he would not make the mistake of attempting a third term in office.
The President spoke at the opening of the ongoing National Executive Council meeting of the All Progressives Congress in Abuja.
Apart from age, the president said he was limited by the two terms stated in the constitution.
“I’m not going to make the mistake of attempting a third term. Besides the age, the constitution makes provision for only two terms,” he said.


Matrix divide each submatrix of two 3D arrays without looping. type controls the matrix multiplication to perform (for each i): 1 - C(:,:,i) = A(:,:,i)\B(:,:) 2 - C(:,:,i) = A(:,:,i)\B(:,:,i) 3 - C(:,i) = A(:,:,i)\B(:,i) Corresponding dimensions of A and B must match appropriately. Other cases (see multiTimes.m) are not yet implemented.

Login
GitHub redirects back to this pack with a
?code
query
parameter, which then can be exchanged for the user-to-server token
using the Client ID
and
Client Secret
credentials. The request for the exchange
cannot be sent to GitHub directly from browsers due to lack of CORS
headers, so we use a small stateless Netlify function to proxy that
request.


Given an array of n integers. Write a program to find the minimum number of changes in the array so that array is strictly increasing.
In strictly increasing array A[i] < A[i+1] for 0 <= i < n
This problem is a variation of the Longest Increasing Sub-sequence problem.
To find the minimum number of changes required to make the array strictly non-increasing is to find the elements that are not part of the LIS.
Algorithm Overview:
1. Find the LIS of the given array. This can be done in O(NlogN)
2. Subtract the length of the array and the length of the LIS.
The above approach can be implemented as follows:

A redesign of Tjetak Name Card page to improve the customer experience when customer want to order.
The Problem
A customer wants to print business cards online through the website: Tjetak.com.
This customer does not have any preferences related to the business card they want to print, but
they want to:
Make a business card with a cheap price and,
Make a bussiness card then completed it in quick time (assume in 1 day
only).
A Redesign is needed because the current interface of name card page is only based on requirement
which is most of people doesn't know much about it.
Current Tjetak Name Card Page
My Role
I am responsible for all aspects of the UX process, from creating the personas, user flow, user
journey, lo-fi until it completed by hi-fi design.
A Persona
The personas is about a new startup founder names Alexander want to create a new name card for his
business with fast and cheap.
User Journey
User journey is the story of user why the user would to use some of service on the internet and found tjetak.com with the services.
Here's the assumptions of user journey that I create for this case:
User Flow
User flow is used to what users would do for the first phase to complete their goals.
They want to go to card name category and then going to this flow.
Result - Part I
Based on the background of the user journey above and background what is the problem that user faced. The result of page that I created is:
I make the estimated time for completed order at the first place.
For the price it's flexible, so the user could input by themself from the lowest price and to higher price, and it would impact to card name category.
The last is I put the delivery option and type of delivery.
Result - Part II
After completed the order we could check our order in order review below:
It's all for this case study.
Any feedback is welcome. you could directly reach me out here.


We are arguably the best joint in town. We offer both sit-ins and home deliveries on our Pizza flavors. We have been doing this over the years with a well preserved culture on good food and perfect services with a dedicated pool of workers that offer exquisite services.
We would like you to sample the various flavors. Welcome

Testing whether tabindex="-1" and aria-hidden="true" will hide an iFrame from Screen Readers
Why would there be such iframes?! Well, I learned recently that people like to use them for behind-the-scenes coding, but they are not supposed to be part of the user interface.
iFrames without any code to hide them from screen readers

Reference models for technology adoption (e.g. The Chasm) are stale.
Need more human and social stuff to understand adoption. Wants/needs/fears/goals vs trends/driving forces/events/black swans.
Every 20-30 years generations go through major shifts.
New trend: modal fluency: users go through seamless movement between different modes of interaction. (Is this really a trend... I don't see DS owners taking their DS play to the Wii, or online. And it's one of those things that's been mooted for yonks now.)
Apologies for poor notes, I'm flagging not blogging...


The locale currency mask directive masks form inputs to display currency propperly for a given locale.
The string value which determines what locale the input should use (ex: 'en-US').
The string value which determines what currency the input should use (ex: 'USD').
The boolean value which determines which side the currency symbol should located.
The boolean value which determines negative values are allowed.

Annotation details¶
Aside from adding \sameword{}
-macros as appropriate the script also converts
all combined unicode characters into single point variants where they are
available. That means that if you compose 006F (o) and 0308 (̈) they will be
converted into the single code point 00F6 (ö). This ensures matching in these
ambiguous cases if the two systems should be mixed. On this, see here
Languages¶
The script is fully Unicode 10 compliant and should therefore handle any language that is represented in unicode characters. Characters that are considered to be part of a word matches the Unicode definition.
It has however not been tested with any languages that are not left-to-right.
If you find any problems with any language, you should file a bug report.
Overlapping apparatus entries¶
In cases where it is necessary to create two apparatus entries that overlap, the
line numbers of the overlapping structure must be indicated manually (the
\xxref{}
can assist with that).
\beginnumbering
\pstart
One %
\edtext{
and two
\edtext{and}{\xxref{start}{end}\lemma{and–and}\Afootnote{overlapping}}\edlabel{start}%
four
}{\lemma{and–four}\Afootnote{del.}}
and\edlabel{end} five.
\pend
\endnumbering
Here the two labels \edlabel{start}
and \edlabel{end}
indicate the
extent of the inner overlapping note.


I opened my briefcase and took from it my Bolshevik Tomato Paste Scoop. I was so pleased with it. I had snapped it up on eBay, where it was going for a song. The song I opted for was “Essay On Pigs” (1968) by Hans Werner Henze. Strictly speaking, this is actually five separate songs, but I got away with it. The Bolshevik Tomato Paste Scoop arrived in the post four days later. I will be sure to take it with me, in my briefcase, on my forthcoming trip, by hot air balloon, to the Lost City of Karencarpenter, far far away, beyond the mountains of madness, where night-penguins fringe a yawning abyss.


PG_TERMINATE_BACKEND
Terminates a session. You can terminate a session owned by your user. A superuser can terminate any session.
Syntax
pg_terminate_backend( pid )
Arguments
- pid
-
The process ID of the session to be terminated. Requires an integer value.
Return Type
None
Usage Notes
If you are close to reaching the limit for concurrent connections, use PG_TERMINATE_BACKEND to terminate idle sessions and free up the connections. For more information, see Limits in Amazon Redshift.
If queries in multiple sessions hold locks on the same table, you can use PG_TERMINATE_BACKEND to terminate one of the sessions, which forces any currently running transactions in the terminated session to release all locks and roll back the transaction. Query the PG__LOCKS catalog table to view currently held locks.
If a query is not in a transaction block (BEGIN … END), you can cancel the query by using the CANCEL command or the PG_CANCEL_BACKEND function.
Examples
The following statement queries the SVV_TRANSACTIONS table to view all locks in effect for current transactions:
select * from svv_transactions; txn_owner | txn_db | xid | pid | txn_start | lock_mode | lockable_object_type | relation | granted ----------+-----------+-------+------+---------------------+-----------------+----------------------+----------+-------- rsuser | dev | 96178 | 8585 | 2017-04-12 20:13:07 | AccessShareLock | relation | 51940 | true rsuser | dev | 96178 | 8585 | 2017-04-12 20:13:07 | AccessShareLock | relation | 52000 | true rsuser | dev | 96178 | 8585 | 2017-04-12 20:13:07 | AccessShareLock | relation | 108623 | true rsuser | dev | 96178 | 8585 | 2017-04-12 20:13:07 | ExclusiveLock | transactionid | | true
The following statement terminates the session holding the locks:
select pg_terminate_backend(8585);

Nicole Scherzinger slammed by X Factor fans after 'motorboating' Louis Walsh
Judge Nicole, 41, became a little wild tonight as she got up close and personal with Louis Walsh - and X Factor: Celebrity fans weren't impressed
by Rose Hill, https://www.mirror.co.uk/authors/rose-hill/Nicole Scherzinger was slammed by viewers this evening after "motorboating" Louis Walsh live on The X Factor : Celebrity.
The judge, 41, became a little wild tonight as she got up close and personal with Louis.
Moving over to hug him, she pressed her boobs into his face.
Fellow judge Simon Cowell didn't appear too phased and was busy clapping in the background.
However viewers were not impressed, insisting that it was supposed to be a "family show".
They also accused Nicole of inappropriate behaviour and that if she had been a man she would have caused an uproar.
One fumed on Twitter : "Nobody bats an eyelid at Nicole forcibly motorboating a fellow judge. Just imagine the furore if a male judge thrust his schnangus into her face. It would be career ending. #CelebrityXFactor."
While another commented: "Why does Nicole always have to be so sexual. Stuffing her boobs in Louis' face #CelebrityXFactor #XFactorCelebrity."
A third remarked: "Nicole sticking Louis head on her tits, what on earth is going on #CelebrityXFactor #XFactorCelebrity."
"Wtf is Nicole doing shoving her breasts in Louis' face? #CelebrityXFactor," another tweeted.
Another wrote: "Umm Nicole rubbing her boobs in Louis’ face... is that ok?! Imagine if Louis rubbed his bits on her face! #CelebrityXFactor."
*The X Factor: Celebrity returns next Saturday on ITV

DAPP Developers¶
DAPP Developer can create a MicroChain and running his DAPP on the MicroChain. He need to deposit enough MOAC in the MicroChain to reward the SCSs running the MicroChain.
DAPP Developer need to make his own MicroChain contract or use some template provided by MOAC.
B1、Deploy MicroChain control contract¶
subchainbase is the contract for the DAPP developers to control the MicroChain. It provides the MicroChain launch and running methods.
The parameters are as following:
- proto：subchainprotocolbase contract address, obtain from MOAC team;
- vnodeProtocolBaseAddr：vnodeprotocolbase contract address，obtain from MOAC team；
- min：min SCSs required to launch MicroChain, suggest value > 3;
- max：max SCS required to launch MicroChaib, suggest value < 100;
- thousandth：default is 1;
- flushRound：MicroChain flush interval between MotherChain blocks, min number is 100;
- The gas limit need set to 6700000 for deploying.
Example:
chain3.personal.unlockAccount(mc.accounts[0], 'passwd',);//unlock the account to deploy
var proto = "0x8fab1913cc......2deb725" ;
var vnodeProtocolBaseAddr = "0x8fab1913c......2db52deb725" ;
var min = 1 ;
var max = 10 ;
var thousandth = 1 ;
var flushRound = 20 ;
var subchainbaseContract = chain3.mc.contract([{"constant":true,"inputs":[],"name":"maxMember",......,"type":"event"}]);
var subchainbase = subchainbaseContract.new(
proto,
vnodeProtocolBaseAddr,
min,
max,
thousandth,
flushRound,
{
from: chain3.mc.accounts[0],
data: '0x6060604052600c601555670d...708e8ee3c23da8b02d0278eb0029',

}, function (e, contract){
console.log(e, contract);
if (typeof contract.address !== 'undefined') {
console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
}
})
B2、RegisterOpen：¶
The RegisterOpen is doing the following tasks:
- Dapp developer call this function on MotherChain to start the MicroChain；
- MotherChain broadcast the call to all the VNODES. If the VNODE contains a valid SCS, it will wait for the selection signal；
- If SCS receives a selection signal, it need to send a transaction to the MicroChain contract to finish the registeration (This is why SCS need to have some initial MOAC deposit).
- MicroChain will collect the confirmations undtil it reaches the max limit as defined in the contract.
The MicroChain chooses in the SCS pool to form the microChain validators. By default, this process is random. The microChain creator can also change the selection process and only allow specific SCSs to join.
Example:
function subchainRegisterOpen(dappAddr,dappPasswd,subchainAddr)
{
chain3.personal.unlockAccount(dappAddr, dappPasswd,0);
sendtx(dappAddr, subchainAddr, '0','0x5defc56c' );
}
Comments:
- dappAddr、dappPasswd：Dapp Developer account and password to make the call；
- subchainAddr: subchainbase contract address;
- data：In sendtx, ‘0x5defc56c’ is a constant to send with. It was generate from the first 4 bytes in the hash of registerOpen() function.
Example:
subchainRegisterOpen('0x1b9ce7e4f15...38913a56cd986786',
‘123’,
'0x6f5b81365fb1d3d...536cc78749af2c')
After registerOpen is called，DAPP developer can use the following methods to check how many SCS nodes registed in the MicroChain:
Method 1：
In the Console, check after call RegisterOpern in subchainBase:
This is to call the nodeCount function in subchainBase contract.
> subchainBase.nodeCount()
Method 2:
In the Console, call the subchain address to check the value of nodeCount (‘0x0e’):
> mc.getStorageAt(subchainAddr,0x0e)
When enough SCS nodes registerd in the MicroChain, continue to next Step: RegisterClose().
B3、RegisterClose：¶
The RegisterClose is doing the following tasks:
- Dapp developer call the RegisterClose function;
- The contract checks if the number of SCS registered is larger than the min number required in the MicroChain contract. If yes, continue. Otherwise, the register is void;
- The contract is broacast to all the VNODEs and SCSs that the registration is closed;
- The registered SCSs receive this broachasting, init the MicroChain and start generating MicroChain blocks.
After RegisterClose，SCSs cannot register through the MicroChain contract. The SCSs registered can participate the and get rewards from the MicroChain.
Example：
function subchainRegisterClose(dappAddr,dappPasswd,subchainAddr)
{
chain3.personal.unlockAccount(dappAddr, dappPasswd,0);
sendtx(dappAddr, subchainAddr, '0','0x69f3576f' );
}
Comments:
- dappAddr、dappPasswd：Dapp developer account and password to send the TX;
- subchainAddr：MicroChain contract subchainbase address;
- ‘0x69f3576f’: constant, generated from the subchainbase registerClose() function by using Keccak256 hash.
Example:
subchainRegisterClose('0x1b9ce7e4f15......e0e38913a56cd986786',
‘123’,
'0x6f5b81365fb1d3......6907fa536cc78749af2c')
Besure to have enough SCS nodes registered befor calling Registerclose. Otherwise you need to start the process again.
B4、Deploy DAPP contract on the MicroChain¶
DAPP contact can be deployed on the MicroChain through directcall. Directcall can be performed under the console using mc.sendTransaction.
- from: The DAPP source account, need to unlock;
- value: Direct call don’t need any mc, you can put any non negative number here, suggest 0.
- to: MicroChain contract subchainbase address;
- gas: Direct calls don’t use any gas, put 0;
- gasPrice: Direct calls don’t use any gas, put 0;
- shardingflag: Need to set value to ‘0x1’;
- nonce: Note this is the nonce for the MicroChain.
- data: The data is generated from compiled DAPP contract. After compiled the DAPP contract, you need to put the BIN as data.
- via: this need to be a VNODE-PROXY address. You can get this address by run a local MOAC VNODE as proxy or use one from others.
To check the deploy results, referring to B6.
Example:
function deploycode()
{
chain3.personal.unlockAccount(mc.accounts[0],'',0);
chain3.mc.sendTransaction(
{
from: mc.accounts[0],
value:chain3.toSha('0','mc'),
to: subchainbase,
gas: "0",
gasPrice: "0",
shardingflag: "0x1",
nonce: 1,
data: '0x606060405234156......9c6697187ac00029',
via: '0x78e1b4584085......e3cff29f11f8d5e08f54dc'
});
console.log('sending from:' + src + ' to:' + tgtaddr + ' with data:' + strData);
}
B5、DAPP function calls¶
To make the DAPP function calls, users also need to make a direct call. First, user need to compile the DAPP function calls and saved in the data section. Then send a transaction to MicroChain address, with correct parameters (B4). The results can be checked later (B6).
Example：
function testSet(num)
{
chain3.personal.unlockAccount(mc.accounts[0],'',0);
chain3.mc.sendTransaction(
{
from: mc.accounts[0],
value:chain3.toSha('0','mc'),
to: subchainbase,
gas: "0",
gasPrice: "0",
shardingflag: "0x1",
nonce: num,
data: '0x4f2be91f',
via: '0x78e1b45840850......ff29f11f8d5e08f54dc'
});
//console.log('sending from:' + src + ' to:' + tgtaddr + ' with data:' + strData);
}
B6、Check MicroChain status¶
The status of the DAPP can be checked through SCS monitor service. User can start a SCS with monitor service by using the RPC option:
- -rpcaddr [addr] SCS turn on rpc ip
- -rpcport [port] SCS turn on rpc port
Data structure：
type Args struct {
Sender common.Address // Dapp owner
SubChainAddr common.Address
}
type ArgsData struct {
Sender common.Address // Dapp owner
SubChainAddr common.Address
Func string // eg:"SetData()", "rpcGetData()"
}
