Changing Workunit Priority to 1 from 0
Hi Everyone,

In order to use the "Use Reliable Host" feature built into the BOINC server software, we must change our workunit priority to 1 from 0. I am implementing this now and will check in over the weekend to make sure everything is running well.

If you have any questions or see any issues, please let me know.

Nbody 1.68 release
Hi All,

A new version, v1.68, of nbody has just been released. I have not yet released the mac multi-threaded version (OpenMP). I will release this at a later date.

In this release we have added a new way of constraining the width of the stream. Previously, we were using a measure of the velocity dispersion in each histogram bin. This led us to fit our parameters quite well. Unfortunately, we found that this may not be the best method in the long run. I have added a measure of the beta coordinate dispersion which, from initial findings, will be (hopefully) easier to fit our parameters with.

As always, please let me know if there are issues.

Thank you all for your continuing support,
Sidd

Reducing Workunits to Unreliable Hosts
Hey Everyone,

I just tried turning on some options to reduce workunits sent to hosts that return a significant number of errors. If you see any issues, please let me know.

Thank you all for your continued support.

Validation Inconclusive Errors
Hi all,

There has been some reports of validation inconclusive issues occurring with the Nbody workunits. It seems to be isolated to the nbody app. I believe this coincided with a database issue on our end. I am working on resolving the issue.

Thank you for you patience and continued support,

New Team Creation Requirement (1 Credit Awarded)
Hello Everyone,

We have noticed an uptick in spam teams being created by users with 0 credits crunched. These teams are often advertising sketchy services and are not created in the spirit of working together to help crunch workunits or build a community. In an effort to combat this, we recently implemented a newer version of reCaptcha during account creation to reduce abuse of the team system by spammers and bots.

This new reCaptcha seems to have helped, but not enough. Effective immediately, we are requiring any new team owners crunch 1 credit to before creating team. In reality, this will not be an issue for anyone signing up for the project to actually contribute to the community. It will however make it vastly more difficult for bot accounts to create teams.

If you have any suggestions for helping us reduce abuse of our website and the team system, please let me know below and we can discuss.

Thank you all for your continued support.

Repealing Net Neutrality Could Affect MilkyWay@home
Hello Everyone,

On December 14th, 2017, the Federal Communications Commission (FCC) plans to take a vote to remove the Title II classification of Internet Service Providers (ISPs). In effect, this will remove the FCC's authority to enforce the doctrine known as net neutrality. Net neutrality is the idea that all traffic on the Internet, regardless of its origin, should be treated equally. This doctrine is responsible for the massive success of the Internet today. It allows any company, institutions, and individuals to host their own websites and web services without the fear of having their web-traffic throttled to accommodate another company, institute or individual who has more money to pay for their traffic to be prioritized. It also prevents ISPs from throttling or being paid to throttle websites for any reason, such as, political, or ideological reasons.

Why is this important for MilkyWay@home? As a research group that survives off of donations from our wonderful volunteers and government grants, we do not have the means to pay for things like paid prioritization, or any other potential ransoms that ISPs may decide to charge in the future to transmit data. This could lead to a decrease in our workunit availability and overall reduction to our abilities to make discoveries. The repeal of net neutrality can also lead to new fees for our volunteers. For example, ISPs will be allowed to sell access to certain websites as part of "bundled" packages. This means to receive workunits from us or any other BOINC project, or visit our websites, you will have to buy into a "bundle" that includes our or other BOINC websites. In our minds, this is not a partisan issue as there is overwhelming support for net neutrality from both parties, (76% of Americans, 81% of Democrats and 73% of Republicans). [1]

If you live in the United States and would like to help protect net neutrality, the best thing you can do is contact your congressmen and senators to let them know how you feel about net neutrality, why it is important to you, and why they risk your vote in future elections if they do nothing to protect it. Additionally, if you would like to help fund larger efforts to prevent the repeal of net neutrality or if you live outside of the United States and would still like to help, consider donating the Electronic Frontier Foundation or the American Civil Liberties Union to allow them to cover the costs of the looming legal battle.

Thank you all for your continued support and I hope for everyone's sake network neutrality can be saved.
