The question of managing unstructured data is very broad and impossible to answer with a definitive correct answer. NoSQL is different than relational databases but the data have some kind of structure. This structure is different than traditional relational databases but it is not correct to call them unstructured.

Adblocks don't fully block facebook ads. To block unecessary facebook clutter, I suggest FB purity. It enables to customize facebook and remove facebook ads.

In case you are using Safari on iOS (version 9 and above):
1. Open web-page
2. Tap Share button (arrow in a box, located in the middle below)
3. Choose option "Request Desktop Site"

There are seems to be also some tools to visualize data by accessing to a SPARQL endpoint (e.g. Apache Jena Fuseki provides the possibility to have a SPARQL endpoint, in addition to publicly available SPARQL endpoints, if that's of an interest). This might be a bit off-topic, but I hope at least related to your challenge :)

It might be possible 1) to also make use of a proxy server, configuring it appropriately in your operating system or in your browser. There are also some free public proxy servers, which are rather slow. Another potential solution is 2) to use one of the so-called DNS redirectors. Be also aware of possible resulting breaches of the respective law :)

One way of watching those videos is changing the proxy server. If you take a proxy server of your home country and put it in your browser, you'll be able to watch every content of that country.

NoSQL is a whole new way of thinking about a database. NoSQL is not a relational database. The reality is that a relational database model may not be the best solution for all situations. The easiest way to think of NoSQL, is that of a database which does not adhering to the traditional relational database management system (RDMS) structure.

Using Html/Javascript you can only select files using the file upload html component (I think Flash / Silverlight wrap this to make things easier but its still sandboxed)
You can however use Java Applets (orwhatever they are called these days), Native ActiveX controls or .Net Controls to provide additional functionality (this hase security implications and required VM/Runtimes Frameworks etc)
Adobe Air or other client side technology might work, but looks like you want to do this in JavaScript. In this case, uploading the file to the server and manipulating from there is the best bet.

One of the possible solutions would be to retrieve the available photo previews into a temporary local folder (keep in mind possible privacy issues), similarly as web browsers require to store web content locally to display it. Wget is a powerful yet simple tool to download content from web servers, supporting pattern matching of files being retrieved.

1) Determine the (potential) URL of the photos from the event of interest on FinisherPix (e.g. the Vienna City Marathon 2017 is apparently an event with the ID 1700, and photos being stored in the form https://fp-zoom-eu.s3.amazonaws.com/1700/1700_000064.JPG ).

2) Construct web content (resource) pattern for Wget (e.g. https://fp-zoom-eu.s3.amazonaws.com/1700/1700_*.JPG).

3) Download multiple available photos for the event of interest to a local preview all at once using Wget (e.g. by executing the command of the type wget -r -l1 -np "https://fp-zoom-eu.s3.amazonaws.com/1700" -P /tmp -A "1700_*.JPG").

Again, be aware of the possible privacy implications resulting from such workaround.

Make use of a time-based scheduler Cron, which is available on Debian (as well as on other Unix-like operating systems). Quartz offers a seamless integration with Java applications. Scheduling a particular script (e.g. restarting server) can be easily done using Cron expressions in form of a string consisting of five or six fields (separated by white space), which are respectively responsible for: minutes, hours, day of month, month, day of week, year.

1) Implement a procedure to restart server (e.g. integrated in Java application or through system script).
2) Make use of Quartz to provide Cron functionality to Java application, in particular to make use of Cron expressions.
3) Provide an option for (privileged/administrator) users to manage Cron expression string for restarting server in web interface.
4) Explain in a short summary the principle of functioning of Cron expressions, providing examples of the most common usages.
