While there has been a lot of type about the little helicopter that was inside the rover running Linux, the rover itself runs BSD. *** ### Practical Guide to Storage of Large Amounts of Microscopy Data (https://www.cambridge.org/core/journals/microscopy-today/article/practical-guide-to-storage-of-large-amounts-of-microscopy-data/D3CE39447BFF5BBF9B3ED8A0C35C6F36) > Biological imaging tools continue to increase in speed, scale, and resolution, often resulting in the collection of gigabytes or even terabytes of data in a single experiment. In comparison, the ability of research laboratories to store and manage this data is lagging greatly. This leads to limits on the collection of valuable data and slows data analysis and research progress. Here we review common ways researchers store data and outline the drawbacks and benefits of each method. We also offer a blueprint and budget estimation for a currently deployed data server used to store large datasets from zebrafish brain activity experiments using light-sheet microscopy. Data storage strategy should be carefully considered and different options compared when designing imaging experiments. *** ## News Roundup ### OpenBSD guest with bhyve - OmniOS (https://www.pbdigital.org/omniosce/bhyve/openbsd/2020/06/08/bhyve-zones-omnios.html) > Today I will be creating a OpenBSD guest via bhyve on OmniOS. I will also be adding a Pass Through Ethernet Controller so I can have a multi-homed guest that will serve as a firewall/router. > This post will cover setting up bhyve on OmniOS, so it will also be a good introduction to bhyve. As well, I look into OpenBSD’s uEFI boot loader so if you have had trouble with this, then you are in the right place. *** ### NextCloud on OpenBSD (https://h3artbl33d.nl/blog/nextcloud-on-openbsd) > NextCloud and OpenBSD are complimentary to one another. NextCloud is an awesome, secure and private alternative for propietary platforms, whereas OpenBSD forms the most secure and solid foundation to serve it on. Setting it up in the best way isn’t hard, especially using this step by step tutorial. MySQL Transactions - the physical side (https://blog.koehntopp.info/2020/07/27/mysql-transactions.html) So you talk to a database, doing transactions. What happens actually, behind the scenes? Let’s have a look.
