"Our immediate calls for assistance at their github were met with hostile and unhelpful comments - after a while, our request was even tagged as "off topic" and closed. We were shocked to receive an even more aggressive reply from them in our Support the next day."

Immediate?  13 days ago, Gulden v2 came out more than 2 month ago
Hostile comments? Maybe short and dry instead of super friendly explaining him basics of how blockchains work. It's github, not slack/forum chat. Some understand the difference, others obviously not.

Other side of the story:
https://dev.gulden.com/a-clarification-on-coinomi/

They (coinomi) demanded money to delist NLG because they could not handle the chain?

And for those who can read a block format:
https://github.com/Gulden/gulden-official/issues/138

LOL he sees a block getting orphaned after the chain tip increased (longer chain), doesn't understand it and demands changes to keep the orphaned one valid (means to invalidate the valid one with the rest of the valid blocks following).
Make a guess what would happen than?

The first block he saw (the orphaned one) was only propagated to a part of the network before it was replaced by the second version (and its followup block).
And to make it clear: There is not 1 blockchain out there that has no orphans and all handle them by themself (see chain reorg).
Orphans are unavoidable and and part of the blockchain design is to handle them.

It's block 682412, so 4/30 was a guess depending on block times.
We passed that block like 30 min ago, now the update is in progress and expected to take a couple of hours

Either
you are a genius coder and I look forward to see your stable code release within the next 2-3 weeks
or
this is your way to say that you need to start reading about the technical details of p2p blockchain technology.

BTC carries the burden of keeping old/long time outdated nodes on the network, limiting the savings alot for another couple versions (translates into years!).
They are on v0.15 and I still see v0.10 nodes on the network.  

During the activation phases (giving users time to update their wallets), Gulden 2.0 will leave old 1.6 nodes step by step behind and is than free of that burden.  
Pretty sure this is part of the magic.
Still doesn't take anything away from the great dev work.

0.00002% of 17m population?
0.0000002 * 17000000 = ? 

 

The number of merchants accepting Gulden directly is already more than 0.0003% of the population.
Gulden slack channel: Number members close to 0.0008% of NL population.
Direct Twitter followers of Gulden (most of them look dutch to me) equals to 0.005% of NL population (indirect followers not included).
Direct Twitter followers of Nocks (here too, most of them look dutch to me) equals to 0.02% of NL population (indirect followers not included).
That's only a few numbers put together quickly. 

Including family members and friends that got talked about it, it looks like a good amount of people to me.

So be careful
For now I hear a couple alarm bells ringing

Anytime since April 4th, 2014. 

Welcome MiningPool(dot)tk/pool/NLG/   
and congratulation to your first block 303747

Damn, what is Prime?
Oh wait, I should know?
Right, I do know!

Clicked a faucet for you, so now you have your donation.

Now act like you are a man/woman and stand to you word: Remove the traces of your latest troll fart from this thread.

It is a usual routine for exchanges to temporary disable wallets for some maintenance, doing it a few coins at a time (not all at once).
This is a good process and nothing to worry about as long as it doesn't take a few hours for a wallet like ours.
Trading can still continue during this time, only transfers (in/out) are getting delayed until the wallet is in active state again.

Edit: Just saw a bigger than usual amount of wallets disabled right now, so it looks more like a general maintenance of their internal server structure.
Still, it's a usual routine they do once in a while.

The block chain is 240MB right now, a zipped bootstrap like 160MB.
Not spammed like the btc chain
As long as you have a decent internet connection there is no real advantage using a bootstap file.

2 days ago I did a full resync on a 32bit system (wallet limited with 6 - 8 connections) in only 17 minutes 

Right now it is better for the for of Gulden to concentrate the volume on less exchanges than spreading it over every bigger exchange that exists.
Lets not loose the focus for Gulden: Use as a currency in daily life.
That's why it is good to get it into the hands of many.
Gulden is still far too young to become victim of speculative investors for quick profit.
What we want and need are the longtime investors that believe in work and future of Gulden.

Said that, a second major exchange that can bring us additional serious investors can become an advantage; as long as it does not only spread the existing trading volume.
That's why I say we don't need to be on every exchange out there; we need to pick those that have to offer us something.
Others will follow anyway over time, no need to pay any of them for it
Better invest that money into Gulden itself

That part stratum+tcp is for mining at a pool, for solo mining I think (long time since I did some solo mining) it is http.
If you get an error message about longpoll, than add -no-longpoll.

Said that, chances are small to get a block solomined with you 6 chip zeusminer, you should better mine at a good pool and get your share there.

Right, the electricity cost can make the difference here.
On the other side something isn't mentioned yet:
https://bitcoinwisdom.com/bitcoin/difficulty
You have to expect a decreasing btc income over time.
"Estimated Next Difficulty:    59,756,916,129 (+4.91%)" means ~5% less btc and those diff changes happen how often a year?
Summarize that over a year to see how much hashrate you have to steady add to keep the btc income stable.
At the end it all depends on how cheap the electricity costs are and how fast you have to get additional equipment for the same amount of btc.

only my 2 sat

BAG sold BOL.com 2002 to an investment group and since 2012 it is owned by Ahold.
Not that I think that makes it easier to convince them

LOL
"You do not know what you are talking about."

Do you even know the difference between retarget time and block time?

Your retarget time (for the diff) is 5 minutes, your block time is 30 seconds!
See here https://github.com/AmsterdamCoin/AmsterdamCoin/blob/master/src/main.cpp#L1104-L1106
Took longer to find the link to your repo than to find those lines.

Oh wait, 5 weeks ago you said in the LiteDoge thread: "... I am not sure if I can help with heavy c++ coding."

Not that the difference between block time and retarget time is 'heavy c++ coding'.

static const int64 nTargetTimespan = 5 * 60; // AmsterdamCoin: 5 minutes
static const int64 nTargetSpacing = 1 * 30; // AmsterdamCoin: 30 seconds
static const int64 nInterval = nTargetTimespan / nTargetSpacing;

block time is 30 seconds, not 5 min
retargeting diff every 10 blocks

That's one of the minor things MaNi was refering to; we want to move away from those years/weeks for the progress bar anyway.

To verify again, I replaced my 64bit wallet with the 32bit version without any problems on win7 64bit.
Smooth replacement, no problems, no surprises

For every day use I don't think you will see a difference between 32bit and 64bit version.

@BartCrypto
Can you give us the exact error message with the version number of the MS VC++ Runtime lib and it's location?
