[DVC]DevCoin - Official Thread - Moderated

Moneychanger is the Open Transactions client for Grandma:
https://github.com/Open-Transactions/Moneychanger

I'd like people to try it out. The first person who does and makes an informative post (at least 50 words) gets four shares, the second 3, the third 2, and the last 4.

I think this will get the Open Transactions Client for Grandmas bounty:
http://www.devtome.com/doku.php?id=devcoin_bounty_now#open_transactions_client_for_grandmas

but because it's a big bounty I want to be sure and I want people to know more about it.

I have tried it on Fedora 17 and on Fedora 19.

Fedora might maybe have some kind of problem with the concept of a "system tray", which seems to be a mac and/or windows concept.

However, it might be the case that more grandmas use windows or mac than use various types of Linux? (Is Android a type of Linux?) so maybe that is okay?

What I could access of it worked, but without any apparent way to make its "system tray icon" actually appear on my screen I was unable to properly use it because for some reason or lack of reason its main menu is in or popped up from the system tray icon. The main windows that appear for example when you first fire it up and it walks you through creating an account and so on has no way to get to the main menu.

I also had problems when I used "ssh -X" to ssh to the Fedora 19 box I built it on and installed it on from my graphics workstation where all the GUI stuff of any X-windows applications I run on various boxes should display. (The graphics workstation is basically just my desktop box that runs nothing itself ideally and instead merely serves as a graphical display terminal from which to run various apps on various boxes.)

When I ran Moneychanger directly from the screen and keyboard and mouse that were directly attached to the Fedora 19 box, Moneychanger fired up okay, but when I used ssh -X from my desktop box, which is still stuck with Fedora 17, the app popped up (on my Fedora 17 box's X-windows display) an error popup saying it could not find any support for a system tray.

So it looked like Moneychanger did think that Fedora 19 itself directly, using its own graphics card to drive its own local X-windows display, did have system tray support, as it did not pop up that error in that situation. But in the real world real use case of having the application run on an application-server box with its graphical display being on a graphics server (X-windows server) on the user's desk, the support for system tray could not be found.

FellowTraveler basically just says Fedora must be using a broken windowing system or something.

#fedora and #gnome type channels on Freenode never responded at all to any inquiries as to what is a system tray and whether gnome (the windowing system) even has such a thing, nor on whether system tray icons are or are not intended to be able to appear on the end-user's remote graphics server (graphical display, graphical terminal, X-windows server) or are deliberately restricted to only working on displays that are directly driven by the graphics card that is in the same machine that the application itself is run on.

I have problems running more machines to test this currently as all my circuit breakers are full almost to popping due to all the mining gear mining, I have all my machines turned off to free up electrical capacity for mining gear. But, I now have put Fedora 19 on a laptop so should now be able to again try to find what the system tray problem is and whether Fedora has such a tray and if not whether I can get one and install it or what.

(Possibly the machines I initially tried with might have broken X-windows installs or broken gnome3 windowing managers or something; the laptop is a fresh clean install so should let me at least find out if the problem is built into Fedora ab initio or was just something my specific old machines might have broken something over the years in the course of updating through several Fedora versions instead of using clean fresh installs from scratch.)

Also, Moneychanger cannot be built on default Fedora 17 lately, because the QT user-interface-editor they now use to create its user-interface is too new for the QT that comes with Fedora 17 to use. The QT that comes with Fedora 19 can build it just fine though.

dvcticker.bugs3.com is capable of saving data over 3 months (I schedule a 15-minutely cron job)

I believe it qualifies for the 18-share DVC-USD chart.

http://devtome.com/doku.php?id=devcoin_bounty_now#devcoin_usd_chart

Can you force the display of the full eight digits after the decimal?

It took a moment to deduce that maybe you are using eight digit accuracy but that your format is losing the trailing zeroes, the current per devcoin value of devcoins was shown as 0.0000011 BTC instead of as (for example, at a wild guess, assuming you really are using eight digit accuracy) 0.00000110 BTC.

Those of us used to quickly visually scanning the number of satoshis are subject to a bit of cognitive dissonance when we see what looks like 11 satoshis instead of 110...

-MarkM-

I am using php, so I just use the round() function.  Should I change the interval from whole BTC to satoshis?  That might be better.

I also am upgrading hosting and getting a domain!  http://devticker.pw

It will be available in about 24 hrs

Does php have format statements? Or maybe a printf (or sprintf) type of thing? A way to tell it how many digits to display even if they turn out to be zeroes?

I would imagine it must, otherwise dollars displays on websites would lack their cents digits or have only one digit of cents instead of two in cases where the least significant digit was a zero, and I have not noticed that being a prevalent dollars-display format on php-based websites in general.

So I am guessing php must have some kind of format-statement in it somewhere? Unless people always do the correct thing in dealing with money of not using floating point at all and instead using integers and themselves manually inserting a dot where they want it when printing the integer number of cents as a two decimals accuracy number of dollars...

You are right! 

Code:

<?php
echo round($price, 2);
printf("%.2f", $price); ?>

I will change it on the new site.

To all:  I have not updated the music on the devcoin video because youtube is giving me trouble... I will keep trying though!

Thanks for your post about Open Transactions, you get 4 shares, the next informative poster will get 3 shares.

[weisoq]

Not an informative post, but for reference there are OT install instructions here: http://opentransactions.org/wiki/index.php?title=Installation
(I haven't tried yet, or moneychanger, as need to read it all a few more times to understand what I'm doing)

I am hosting a scavenger hunt: http://www.devtome.com/doku.php?id=scavenger_hunt_admin_eeh_1

Try your luck and be the first person to win the prize!

[smeagol]

There is an 18 share bounty for an exchange or marketplace.  There are three people eligible for the award, and here is how we plan to divide the shares:

Tagbond: 9 shares for devcoin integration
Sidhujag: 6 shares for working with Mark to get devcoin onto tag bonds exchange
EEh: 3 for tagbond site http://devcoin.tagbond.com/

Does that seem fair to all?

Also, @sidhujag, is mark the markm, or some other Mark?

Please reply with some feedback on the division, and if you have a dispute please add reasoning to why you should get more or less.

After four days pass with no objections, the shares will be officially put into the bounty file.

[eeh]

Thanks for the share!

By the way, anyone wanting to be part of the community, please send me your Tagbond ID number or submit an invitation request to devcoin.tagbond.com.

Smealgol, I would be willing to forfeit a share to sweeten the pot for other outstanding bounties, if that's helpful. I would like to forfeit one share and give it to unthinkingbit to either keep or redistribute. If it's too much fuss, then disregard.

[shakezula]

If I may, I'd like to submit this installer for the remaining bounty:

http://media.andarazoroflove.org/Devcoin-Installer.exe

This is a commercial-grade installer, creates shortcuts on the Desktop for Devcoin and has a brief intro to Devcoin in its about dialog.







It has full uninstall support and is built using the Devcoin and devcoind binaries from the official Devcoin site. It also contains a link back to Devcoin. Feedback is appreciated, nearly every item in the installer can be customized and I hear by pledge to maintain the installer upon future releases of the client.

[Unthinkingbit]

Emfox gets 12 shares for the first round countdown clock:

..
I've done that, intergrated with my faucet page: http://faucet.d.evco.in/ you may find it on the header of the faucet.


Edit: incase of interest, here's the code, https://github.com/emfox/devcoin-faucet/commit/ea7ec0b3c1aa23e80de6441de37cc59955364892

Hunterbunter gets 6 shares for the second clock:

If that's acceptable for any bounty, my address is: 1LHVxAkzcN8BzSdrT7J2W3CCpiz5Rgj72E

Edit 1: Hmm although I seem to be getting a different time to you lot - looks like I had a local time in there...fixing atm

Edit 2: Nope I'm not seeing why I'm getting a different ETA. At this present moment it's 15th Dec 14:04 UTC, there are 2106 blocks to go (120,000 - 117894), which is 21,060 minutes to go = 351 hours converts into 14 days and 15 hours. Going by this, the target date and time should be the 1400 on the 29th of Dec plus 15 hours, or 30th December at 0500. I think I'm correct.

No awards remain, the bounty is finished.

Hunterbunter, since this is your first time on the bounty list, please check that your address is correct at:

For anyone with Windows, please test this installer, the first informative post (at least 50 words) gets 2 shares, and the second 1 share. Once someone posts that they used the installer successfully, Shakezula will get the bounty.

The 6 shares were decided a long time ago, when we didn't have much money:
http://www.devtome.com/doku.php?id=devcoin_bounty_now#windows_installer

Today we can afford more, so I suggest the bounty be boosted to 12 shares, also Shakezula would get 1 share ongoing as long as he maintains the installer upon future releases and fixes any problems that come up. Any objections, or should something be changed?

[emfox]

though I think it's a not so hard task, maybe 10 or 12 shares are enough.

After Weisoq's post:

Countdown clock - all it needs is a spreadsheet link, could probably just be added to smeagols dvc price site:
Using an old start point for calc: In A1 enter '12/05/2013  21:50:00' (date formatted, this is GMT for ref if want to be specific). In A2 enter current DVC Block. In A3 (also date formatted as above) type =A1+((120000-89150)/((A2-89150)/(NOW()-A1))). Right now that gives 31/12/2013 10:24 GMT

I agree that it's not so hard, so I suggest 12 for the first person to accomplish it, and 6 for the second.

Hello, We are both correct.

Since the hashpower of the whole dvc network varies from time to time, one block is not accurately generated in 10 minutes, sometimes longer and sometimes shorter.
As you use 10 mins as one block time, And I using average time of the older blocks (e.g. 1000 blocks before today) as block time. these two method is both ok, and the result won't be too different, maybe in one or two days.

Hello, I installed it, and my Anti-Virus (Eset Smart Security 4) said it an 'Unknown NewHeur_PE virus", and the devcoin.exe was removed. don't know what happened...

Edit: I use the one from http://dls.21stcenturymoneytalk.org/dls/devcoin/devcoin-win32.7z, also said it's the same virus. I suppose this is the official devcoin.exe ? so not the installer fault, there's something error with the original exe.

Very interesting! Yes, this is the devcoin-win32.7z from that same link simply packaged in to an installer. I know quite a few coins come up as false positives--could this be similar? Here's looking forward to a newer build!

I ran it through Virustotal and only one thing flagged it as a trojan (Dr. Web). The anti-virus on my computer doesn't hate it either. Installer seems to run fine, accesses the same %appdata files as my previous installation. Seems to be making connections and has an accurate count on the blocks according to the devcountdown site. I'm going to do a faucet test, and will update this post when I get results (EDIT: which depending on if this faucet really does only pay out on the end of the round may be a very, very, very long time).

Edit: Also noticed the same bug that the label field for each address gets cut off so I can't see the text, just a very thin strip at the top, and maybe a few pixels of the characters.

Edit: Just ran the unintaller after backing up my wallet, then restarted my computer. It left all the %appdata files, which is good for not deleting your wallet.dat file. Might be something to mention in an uninstall dialogue in case people want to remove all traces from their computer so they at least know where to look. I've just reinstalled the client and everything looks normal.

On an unrelated note, I've noticed that the dvc client always takes a proportionally really long time to load, especially considering its size and (at least superficial) simplicity.

Giftculturewriting, I sent you 23 devcoins so you can see if Shakezula's version works completely, please post or message me when you receive them. You get one share for your post:

It has to download the receiver files the first time it runs. After that it should be able to grab them from disk quickly, I don't know why it would be slow then.

This month there are 3 writers earning 46% of all devtome earnings (of ~30 writers). One of them is 120 shares! If your rating method is going to bound between <1 and >1 doesn't the max round share need to be cut. Not just because of the absolute number and absolute equivalent fiat but because the larger shares also serve to undermine all others.

There was a thread discussion on this and nobody seemed to object to something around 30-40, including these writers:
Wiser: https://bitcointalk.org/index.php?topic=233997.msg3781834#msg3781834
Matt608: https://bitcointalk.org/index.php?topic=233997.msg3782941#msg3782941
Markm: https://bitcointalk.org/index.php?topic=233997.msg3782966#msg3782966

Wiser even wrote a previous article on the issue:
http://devtome.com/doku.php?id=on_writing_and_market_forces#capping_the_number_of_shares_per_round

Since the admins want it to be lower, the max words counted has been changed to 50,000, effective in round 31. The code only has a limit for words counted, not total shares. Because the rating can go to 1.5, that means a max payout of 50 x 1.5 = 75 shares per writer. Also the weighting for ratings has been boosted to 60%, the categorization weighting has been increased to 10% and the popularity weighting has been reduced to 30%. The other reason the popularity rating has been reduced is because advertising is cheap and can otherwise boost the popularity so much that it overwhelms the actual quality. I want people to link to their articles and talk about them, because that lasts for a long time, but advertising is a short term popularity boost that skews the earnings. The highest normalized rating of the prolific writers is 1.07, so with a higher rating weighting, the current high earners will have a lower payout.

[Hunterbunter]

Is this bounty still open?

http://www.devtome.com/doku.php?id=devcoin_bounty_now#devcoin_usd_chart

The dvc/usd chart.

I've coded up a webserver that gets the averages from a few different places, but I couldn't find a long term history of DVC.

The chart is here: http://dvcusdchart.blisteringdevelopers.com

It's filling up with data as I just reset it after testing, and it'll log and show data indefinitely. If people want more options etc, say what you like and I'll code it in. I'll make a few more tweaks to make it clearer what's what, but it's up and running now in any case.

EDIT: Obviously it looks a bit silly now but that's because data's just started collecting...it should fill out soon enough
