building an opensource collection of 'net services
hi there! im mia :) im a computer nerd with too much time on her hands.
im making this post to bring a project of mine into the world; a fully opensource and collaborative collection of online tools. this will grow over time, but for now, there is one thing active and two planned. (read on below)
CalicoDrive
a nextcloud instance! currently offering a bunch of very useful things:
50GB of free cloud storage
a Markdown notetaking tool
a shareable, open calendar
a photo gallery
web bookmark storage, and
some organisation and collaboration tools.
many of the cloud storage services we rely on are corporate, and require exorbitantly priced subscriptions. alongside that, data on them is often subject to a huge array of impenetrable terms/conditions.
what makes this different? firstly, your data is controlled by you. it is entirely encrypted on disk and can only be decrypted with your selected password. you own the data the same way you would were it on an external hard drive or flashstick.
secondly- its free! while you can pay 20$ once off or 5$ a month to upgrade storage quota and support the project, the core of it is entirely and utterly free to use.
matrix.calicocore
(full disclaimer- this service isn't online yet. it's planned to be active within the next month at the very maximum, very likely sooner.)
what's matrix? i am absolutely sure you've heard of IRC- internet relay chat. im also sure you've heard of discord.
matrix is a modern federated chat protocol- if you took the best of IRC, and you took the best of Discord, and combined them into an opensource and *free* protocol for real-time messaging? that's matrix, baby!
matrix functions similarly to the fediverse (more on that later). when you sign up, you select a homeserver, which is the infrastructure your account is hosted on. your homeserver determines who you're federated with, your most easily accessible spaces, and the little tag at the end of your name.
so what's matrix.calicocore going to be? a homeserver! the idea here is to bring communication and community into our hands, and away from the hands of big tech corporations who really don't care about us. it'll be federated with other spaces and servers, and run collectively.
fedi.calicocore
if you've ever used mastodon, fedi.calicocore will be a server compatible with it. this is still in the very very early stages as a project, so i cant detail much, but stay tuned.
things to note, disclaimers, etc
this project is in its early days. i cant guarantee perfect stability, though it has been tested and run for a few days already. please don't expect a perfect replacement for existing services YET.
secondly, in regards to calicodrive; your data is fully encrypted in two ways, both within the nextcloud instance and on the physical spinning rust. this means if you majorly forget your password, there's a possibility of losing it- but that trade-off is worth it for the security.
this all sounds great! how can i sign up?
for now, this is the link to the nextcloud:
https://drive.calicocore.space
in the very near future, there'll be a central discussion space on the matrix, too, which you're encouraged to introduce yourself on!
lastly:
who is this for?
these services and tools are made by a disabled trans woman. they will prioritise people vulnerable on the current internet, and focus on building a safe space for trans, non-binary, and queer people; as well as disabled people and people of colour.
you can sign up if you are not one of these, however you will be expected to defer to the marginalised members and be generally respectful of the purpose of the space!

Skittering Data Harvesters
Keeping your data secure is tricky. Every time you send a message electronically there is a chance of digital eavesdropping. There is not such thing as total security— your goal is to minimize risk.
So you secure your home network— VPNs, encryption, not a single ‘smart’ appliance. Ad blocker on everything, chat only on closed platforms. You do your best to minimize and anonymize your digital shadow.
But. you’re still getting targeted ads? You get a loan offer for your exact credit debt?
And then you lift your wireless router while cleaning and see a metallic shimmer as something scurries off the back of the table.
Of course. You’ve got bugs.
Literal and Figurative Bugs
As more people install ad blocker and opt out of data collection what are advertisers going to do? Stop collecting every shred of data they can about you? That sure doesn’t sound like capitalism. Turning to shady data collection by legally separate 3rd parties? That sounds a bit more likely
So in come bugs, which are small, cheap data sniffers that crawl themselves into place, collect data until their storage is full, crawl back to a public network and upload your cache. Repeat
They come in hundreds of varieties— colors, features, specializations. Most look like some variation of beetle (a good design is a good design)
They get past digital security by crawling past physical security. They are not looking at what sites you visit— they are clinging to your laptop cloning your entire hard drive. It latched on to your purse when you set it down grabbing coffee, and now you can’t get them out your apartment. You smashed a few and keep seeing more, so you are certain they built a Queen (you found the remnants of your old phone— they must have stripped it for parts)
You also learned you can’t just stomp them and throw them away. You broke the shell but the data is still there. And turns out they don’t just clone their bodies— they clone their data. So they all have your data. And they are going to sell it.
How is this even grey area legal? Because it is anonymous. They don’t target, they infect. The data is random and disorganized. Overwhelming noise to signal ratio. They are supposed to scrub all identifying details, bank info, etc.
So the reality is that it is horrific and predatory but hugely beneficial to advertisers so regulation is minimal and the legal battles protracted.
Oh, and part of the reason it’s so hard to control is that it is an opensource project. The software is on github and parts off the shelf. The hundreds of varieties of the hundreds of competing companies, trying to out perform each other, trying to snipe data from each other.
But no one is sure who wrote the original program (the github author claims to have found it on a forum and the thread gets more tangled from there)

Fivetran and BigQuery for automated fraud detection
Tumblr media
What is fivetran?
Fivetran is a modern, cloud-based automated data movement platform, designed to offer organizations the ability to effortlessly extract, load and transform data between a wide range of sources and destinations.
Is fivetran opensource?
In 2012, Fivetran was developed as a managed, closed-source ELT solution.
Businesses require quicker data analysis and predictive insights in today’s dynamic environment in order to recognize and handle fraudulent transactions. Generally speaking, combating fraud using data engineering and machine learning involves these essential steps:
Data acquisition and ingestion: To ingest and store the training data, pipelines across multiple, disparate sources (file systems, databases, third-party APIs) are established. The development of machine learning algorithms for fraud prediction is facilitated by the abundance of valuable information present in this data.
Data analysis and storage: To store and process the ingested data, use an enterprise cloud data platform that is scalable, dependable, and high-performing.
Development of machine-learning models: Creating training sets from stored data and applying machine learning models to it in order to create predictive models that can distinguish between authentic and fraudulent transactions.
When developing data engineering pipelines for fraud detection, the following issues frequently arise:
Scale and complexity: When an organization uses data from multiple sources, ingesting that data can be a challenging process. Building internal ingestion pipelines can take weeks or months of data engineering resources, taking important time away from primary data analysis tasks.
Maintenance and administrative work: Manual data administration and storage, including cluster sizing, data governance, backup and disaster recovery, and data storage, can seriously impede business agility and postpone the creation of insightful data.
Steep skill requirements and learning curve: Implementing and utilizing fraud detection solutions can take a lot longer when a data science team is assembled to build machine learning models and data pipelines.
Three key themes need to be prioritized in order to effectively address these challenges: time to value, design simplicity, and scalability. These can be handled by utilizing BigQuery for sophisticated data analytics and machine learning capabilities, and Fivetran for data movement, ingestion, and acquisition.
Fivetran streamlines data integration
Unless you happen to be living it and dealing with it on a daily basis, it’s easy to underestimate the challenge of reliably persisting incremental source system changes to a cloud data platform. Their DB2 source required the addition of a new column, which set off an arduous process that took six months to complete before the change appeared in their analytics platform.
The company’s capacity to supply downstream data products with the most recent and accurate data was severely impeded by this delay. As such, any modification to the data structure of the source caused lengthy and inconvenient outages for the analytics process. The company’s data scientists were forced to sort through out-of-date and incomplete data.
To create efficient fraud detection models, all of their data had to be:
Curated, contextual: The data must be of the highest caliber, credible, transparent, and reliable, and it must also be unique to their use case.
Timely and accessible: Data must be high-performing, constantly available, and provide seamless access with well-known downstream data consumption tools.
The company selected Fivetran primarily because of its ability to handle schema drift and evolution from multiple sources to their new cloud data platform in an automated and dependable manner. Fivetran’s more than 450 source connectors enable the creation of datasets from a variety of sources, such as files, events, databases, and applications.
The decision changed the game. Fivetran’s reliable supply of high-quality data allowed the company’s data scientists to focus on quickly testing and improving their models, which helped them get closer to prevention by bridging the knowledge gap between insights and action.
The fact that Fivetran automatically and dependably normalized the data and handled any necessary changes from any of their on-premises or cloud-based sources as they moved to the new cloud destination was crucial for this company. Among them were:
Modifications to the schema (including additions)
Table modifications (adds, deletes, etc.) within a schema
A table’s columns can be added, deleted, soft deleted, and so forth.
Data type mapping and transformation (with SQL Server serving as an example source)
The company chose a dataset for a new connector by simply telling Fivetran how they wanted changes to the source system to be handled; no coding, configuration, or customization was needed. Based on particular use case requirements, Fivetran set up and automated this process, allowing the client to decide how often changes would be moved to their cloud data platform.
Hoe does Fivetran replicate databases
Beyond DB2, Fivetran showed that it could handle a broad range of data sources, including other databases and a number of SaaS applications. Big data sources, particularly relational databases, could handle substantial incremental change volumes with Fivetran. The current data engineering team was able to grow without adding more employees thanks to Fivetran’s automation. Business lines were able to start connector setup with appropriate governance and security measures in place thanks to Fivetran’s simplicity and ease of use.
Complete data provenance and good governance are essential in the context of financial services companies. These issues are addressed by the newly released Fivetran Platform Connector, which offers quick, easy, and nearly instantaneous access to rich metadata related to any Fivetran connector, destination, or even the entire account. End-to-end visibility into metadata (26 tables are automatically created in your cloud data platform – see the ERD here) for the data pipelines is provided by the Platform Connector, which has no Fivetran consumption costs. These pipelines include:
Source and destination lineage: schema, table, and column
Volumes and usage
types of connectors
Records
Roles, teams, and accounts
Financial services companies can better understand their data thanks to this increased visibility, which builds confidence in their data initiatives. It is a useful instrument for supplying data provenance and governance, which are essential components when discussing financial services and the data applications they use.
The scalable and effective data warehouse of BigQuery for fraud detection
BigQuery is an affordable, serverless data warehouse that is efficient and scalable, which makes it a good choice for enterprise fraud detection. Because of its serverless architecture, data teams can concentrate on data analysis and fraud mitigation techniques by reducing the amount of infrastructure setup and maintenance that is required.
Some of BigQuery’s main advantages are:
Faster generation of insights: BigQuery enables quick identification of fraudulent patterns and rapid data exploration by running ad hoc queries and experiments without capacity constraints.
Scalability on demand: BigQuery’s serverless architecture automatically adjusts its size in response to demand, preventing overprovisioning and guaranteeing that resources are available when needed. Data teams will no longer have to manually scale their infrastructure, which can be laborious and prone to mistakes. Understanding that BigQuery can scale while the queries are running or in-flight is crucial because it sets it apart from other contemporary cloud data warehouses.
Data analysis: BigQuery datasets are capable of storing and analyzing financial transaction data at nearly infinite scale, thanks to their ability to scale to petabytes. This gives you the ability to find hidden trends and patterns in your data for efficient fraud detection.
Machine learning: Using straightforward SQL queries, BigQuery ML provides a variety of pre-made fraud detection models, ranging from anomaly detection to classification. This facilitates quick model development for your unique requirements and democratizes machine learning. Here is a list of the various model types that BigQuery ML supports.
Model deployment for large-scale inference: Google Cloud’s Vertex AI can be used to make predictions in real-time on streaming financial data, even though BigQuery only supports batch inference. Use Vertex AI to deploy your BigQuery ML models and receive instant insights and actionable alerts that will protect your company in real time.
Fivetran and BigQuery work together to solve a complex problem with a straightforward design: a fraud detection tool that can produce actionable alerts in real time. In the upcoming blog series, we’ll concentrate on developing ML models in BigQuery that can precisely predict fraudulent transactions and implementing the Fivetran-BigQuery integration in a hands-on manner using an actual dataset.

The Free Lossless Audio Codec (FLAC) is the most well-liked lossless format, making it a good selection if you wish to store your music in lossless. While the primary goal of. an audio converter software is to transform audio from one format to a different, there are different features you need to look for to raised manipulate the audio. For instance, a program that may extract audio from video can save you time as you don’t have to use a separate program to do the same. Click on Convert to convert your AIFF file(s).
To convert songs currently in your iTunes library, open the software program and discover the Preferences menu from the iTunes dropdown on a Mac or Edit dropdown on a Windows laptop. Next, click on the Basic tab, then find the Import Settings within the lower part of the Preferences window. After that, click the dropdown subsequent to Import Utilizing, select the format and click on OK to save lots of that import format as the default setting. iTunes permits for batch changing, so the ultimate step is to select all the files you wish to convert, click on the File menu, then select Convert and click on on Create MP3 Version. If you happen to chose a unique output format, it shows that format moderately than MP3.
Audio recordsdata are available various totally different codecs. Some are lossy, comparable to AAC and MP3; they save area in comparison with the unique recordsdata, but a number of the authentic knowledge is lost throughout compression. Some codecs are lossless, resembling Apple Lossless, FLAC, and SHN; these files may be transformed again to their unique kind with out the lack of a single bit. Finally, some are uncompressed, akin to WAV and AIFF; they signify the exact information from a CD or a grasp.

A most of 18 surround channels, stereo down combine channel and bit stream indicators with non-PCM coded data can also be stored within the file format. RF64 can be utilized in the entire programme chain from capture to editing and play out and for short or long term archiving of multichannel information. He gave me his recording in aiff format for some reason. I pulled it into S1 with no problem and exported it as a stem in wav format so all recordsdata were in the identical folder. As soon as I sync the files collectively I begin to notice a drift because the recording progresses, it is noticeable after a minute or so.
Hamster Free Audio Converter is claimed to work with Home windows 7, Vista, XP, and 2000. • You can even email the converted file URL to others. I have tried removing theaiff extension on sound recordsdata and dragging them into storage band. It worked for a couple of files however it’s actually hit or miss. File any reside classes or unable to obtain music from any online websites.
The worst thing about FileZigZag is the time it takes to add the audio file and obtain the link in your e mail. Nevertheless, most audio recordsdata, even long music tracks, come in a reasonably small dimension, so it isn’t often an issue. Select which audio information you want to merge. These might be added out of your laptop or system, by means of Dropbox, from Google Drive, or from some other online supply that you just hyperlink.

Should you’re certain you have got a 16-bitWAV or AIFF file at a 44.1kHz sample fee, and it still will not import into the SPD-SX, then the file might have embedded metadata, or “tags,” that are causing the error. This could happen with recordsdata that come from DAWs (“Digital Audio Workstations”), other audio packages, or sample libraries. You possibly can strip this extra info from the file by changing it to Apple Lossless or FLAC format. After converting to Apple Lossless or FLAC, convert that file back to WAV or AIFF, sixteen-bit and forty four.1kHz.
I do not disagree at all – and I will expand upon this crucial topic quickly. Tagging is the KEY to a correct music system and wendiweathers98.hatenablog.com people get very touchy about it – and understandably so. For those of us that have invested tons of of hours curating and sprucing our metadata, we want that point and personal touch to be honored. I do suppose Roon does not respect that enough.

Telegram?
I’ve mentioned Telegram before, but stopped short of writing an introduction about it since we probably won’t really taking the whole moving thing seriously. However, it seems tumblr’s starting to screw up with its UI & user posts AGAIN, while some simmers are worried about SFS. I’d like to explore the possibility to use Telegram as an alternative. Besides, Telegram is a powerful and useful tool that worth trying even for personal use. I'd like to share what I’ve learnt about it and how we can make use of it as an ordinary user and a simmer. You can find other much more comprehensive tutorials or user guides on the internet.  
What is Telegram?
Telegram is a social platform founded by a Russian IT expert/billionaire Pavel Durov, who created this message app to defend the freedom of speech against the Russian government. It is now funded by a dedicated foundation, proving a highly-encrypted message service and popular among tech-savvy. Learn more about Telegram: Telegram FAQ
Pro:
Safe & Stable-as mentioned above. This is why I think Telegram is better than most of other potential alternatives like Pillowfort, Waterfall (not stable enough with funding risks), Discord (closed community with questionable shareholder Tencent, Telegram allows preview historical records before joining in) . Its background, source of funding and user base guarantee it won’t be gone or dramatically change after a buyout, at least not for a foreseeable future.
(Nearly) Unlimited file storage- Telegram allows its users to upload all kinds of files with the only restriction of up to 1.5GB/per file. All the chat records or pictures, videos are all saved to the could. We could use this to diversify the risk from SFS. Besides, Telegram provides both mobile and desktop version. For example, I often drag the songs I like to the desktop version and then download and save the files to my smart phone when I decide to change my ring tone or alarm. This is also handy when I need to compare the reference photos to the sim I’m creating in CAS. All I have to do is to paste the link to these reference photos with the desktop version, then I can easily check them up with my phone.
Channel vs Group- Telegram allows its user to create channels to broadcast (you can subscribe certain channels to keep up with the latest info) and groups for group chat (pretty much like FB or Line chat room but allows up to 200,000 members)  I think we can have multiple groups for like cc release, roleplay, challenges or events, basically everything we have with Discord, and at least one channel as TS3 bulletin, broadcasting the latest news in the community. Each simmer can also set up their own channels & groups to interact with their followers.
Search and categorize by tags- We can use tags to sort out the cc like what we do with Tumblr. Moreover, Telegram provides a cross-channel/group tag search system. 
Powerful Bot-This is probably the most innovative advantage of Telegram. Bot can help you with all kinds of tasks, even more useful than Discord. 
  -As a simmer, you can use the bot to make posts to different        channels/groups simultaneously, for instance, I write a post about my new cc  on my personal channel and the bot will automatically post it to the cc update group.  There’s also inline blot can help non-English speaker to translate the messages when needed, like Translate Me-bot or ReadUp Inline Translator. 
As for personal use, you can use  @utubebot  or @YouTube Audio Downloader to download videos from  YouTube, or upload a file and create a shareable link with @TGhost_bot, or search for meme/gif with @imagebot​ and ofc @Feed Reader Bot to subscribe RSS feed. Telegram also provides numerous free stickers and you can make custom ones with @stickers &  @big_text_bot. Btw, Telegram allows its users to customize the UI theme.
You can also create your own bot with Telegram’s opensource API.
Proxy Server-Users in Russia and Iran won’t have to use telegram via VPN. The official bot @mtpro_xyz_bot will automatically protect users in these regions once properly sets up.
No NSFW censorship- I think this one is pretty self-explanatory.  
Con-
Registration requires your phone number- Telegram starts as a message app and develops into a platform for multiple communities later. Hence, it requires a valid phone number during registration. There are also ways to bypass this restriction, like using a virtual phone number. BUT! It would be a problem if someone else gain access to this number after you. I don’t recommend that. If you worried about privacy, you can decide who can see your phone number in the setting. I turned mine off as soon as I finished the registration process.
Telegram is banned in Russia, Iran and China as its wide use among activists and dissidents during protests (ie, Hong Kong.) Simmers in these regions will need to use Proxy or VPN to access. 
Requires more time and efforts to learn and adopt its powerful functions
Of course the best part will be we can finally say goodbye to Tumblr without worrying about our posts being swallowed or flagged, the automatic unfollowing function, or the possibility of find the blogs we worked on for years just disappeared overnight.    
I’ve been observing Telegram for quite some time, I think it worth a shot. what about you? Moving to another platform will be difficult, but I kinda tired of complaining over Tumblr.

FreeNAS Nedir?
Merhaba,
FreeNAS Nedir? isimli bu yazımda sizlere homelab ortamında kullanabileceğiniz hem de opensource bir storage ürünü olan FreeNAS hakkında bilgi vereceğim. Öncelikle şunu söylemem gerekiyor ki ben de ilk başlarda FreeNAS’ı aşağıdaki ortamda kullandım.
VMware Home Lab
FreeNAS Nedir?
Makaleme başlamadan önce TrueNAS ve FreeNAS ‘dan bahsetmek istiyorum. FreeNAS’ın ismi yakın bir zamanda değişti ve TrueNAS Core ismini aldı. Tabiki FreeNAS ile aynı özelliklere sahip ancak FreeNAS’e ekstra olarak yeni özelliklerde içinde barındıracaktır. Bu konu ile iligli duyuruyu aşağıda görebilirsiniz.
https://www.ixsystems.com/blog/freenas-truenas-unification/
FreeNAS ilerleyen günlerde ismini değiştirecek ve TrueNAS Core ismini alacak. Ancak şuanda TrueNAS Core production ortamlarında kullanımda değil. Kısa süre içerisinde production ortamlarında kullanmaya başlayacağız.
FreeNAS Nedir?
Ben makaleme FreeNAS Nedir ile başlayacağım ancak bu isim yakın bir zamanda değişecek.
FreeNAS Nedir?
FreeNAS kesinlikle kullanmanız gereken opensource bir storage yazılımıdır. Hatta zaman geçtikçe aslında bir storage markası olmaya kadar ilerlemiştir. Freenas ilk olarak 2005 yılında Olivier Cochard-Labbé tarafından kendi file storage ihtiyacın karşılamak amacı ile yapılmıştır. FreeNAS o dönemde yapılırken, FreeBSD üzerinde geliştirilmiştir. Hatta FreeNAS ismide aslında buradan esinlenmiştir. O dönemlerde bu şekilde bir ürün çok çok fazla olmadığı için bu projeyi duyanlar hemen bu projeye ilgi gösterir ve FreeNAS ile ilgili bir canlı topluluk oluştu. Böylece FreeNAS gereçek bir ürün olarak şekillenmeye başladı. File Storage ihtiyacını karşılamak için oluşturulan ürün kısa bir zaman içerisinde, file sharing, media streaming özellikleride eklendi.
2010 yılından itibaren Cochard-Labbé, FreeNAS projesini devam ettirmek için artık yeterli zaman ve kaynak sağlayamadı, bu yüzden kontrolünü genel olarak open source diye tabir ettiğimiz açık kaynak yazılım desteği ve FreeBSD desteği ile tanınan bir şirket olan iXsystems’a verdi. Bunu, büyüyen bir FreeNAS geliştirme topluluğunun ihtiyaçlarını karşılamak için yazılımın güncellenmesi ve modernizasyonu ve proje altyapısının geliştirilmesini içeren önemli bir geliştirme çabası dönemi izledi. iXsystems geçtiğimiz günlerde
Kullanıcı arayüzü tamamen yeniden yapıldı ve ZFS pool‘lar için disk şifreleme ve kernel’de olmayan hizmetlerin kurulumunu destekleyen bir 3 party eklenti sistemi gibi özellikler eklendi. Bugün, FreeNAS, her sürüm için yüz binlerce indirme ile çok aktif bir geliştirme aşamasındadır – kuruluşundan bu yana toplamda 5,5 milyondan fazla indirme olmuştur.
Yazımın başından buraya kadar okudğunuzda FreeNAS sayesinde bir opensource storage oluşturabildiğini anlamış olmanız gerekiyor 🙂 FreeNAS ile evet storage ihtiyaçlarınızı çözebiliyorsunuz ancak iXsystems sadece FreeNAS’ı bize sunmuyor. FreeNAS, home ve SMB gibi ortamlarda tercih edilirken daha büyük ortamlarda kullanılmak üzere çıkarmış olduğu ürünlerde bulunmaktadır. Örneğin TrueNAS isimli ürünü ile  kritik BT ortamında bulunan ihtiyaçlarınız karşılayabilirsiniz. TrueNAS kurumsal düzeyde bir depolama yani storage’dır. TrueNAS sayesinde, failover, performans ayarları, raporlama ve hem donanım hemde yazlım seviyesinde 7/24 destek ve bakım alabilirsiniz. Ancak yazımın başında da belirttiğim gibi FreeNAS’ın ismi artık TrueNAS Core olarak değişecektir. Ancak enterprise müşteriler için TrueNAS yine kullanılmaya devam edecek.
Ben bu yazımda FreeNAS Nedir? hakkında bilgi vereceğim, TrueNAS’ı ayrı bir makalede anlatırım eğer merak eden olursa 🙂 FreeNAS’ı aslında FreeNAS yapan yani başarılı bir opensource storage haline getiren ZFS ‘dir. ZFS diye burada bahsettiğim aslında dosya sistemidir.
FreeNAS’ın temel özelliği ZFS’dir (veya “Zettabyte” File System). Başlangıçta Sun Microsystems tarafından geliştirilen ZFS , büyük depolama kapasitesi ve silent data corruption, volume management ve RAID 5 “write hole” gibi birçok depolama sorununu ele almak için tasarlanmıştır.
ZFS’nin yazma üzerine kopyalama teknolojisi, çok etkileyicidir çünkü bu teknolojiden dolayı performans alınmaktadır.. Veriler diske yazılana kadar data block’lar güncellenmediğinden, tipik RAID write hole sorunu ZFS için geçerli değildir. ZFS ayrıca, snapshot alındığı sırada mevcut olan dosyaların bir parçası olan blokların silinmesini önleyerek çalışan bir snapshot özelliğini de destekler. Bu bloklar daha sonra değişmediği sürece, snapshot’ı  korumak için neredeyse hiç alan kullanmaz. ZFS deduplication’a benzer bir şekilde çalışır ve hangi bloklarda hangi blokların kullanıldığı tabloları korur.
FreeNAS o kadar güzel bir ürün ki, grafik ara yüzünde nested olan ZFS dataset’lerinin yönetimini sağlayabilirsini ve bunu destekler. ZFS dataset’lerinde, her dataset için compression ve data deduplication’ı yapılandırabilirsiniz. Yani bu işlemleri dataset bağımsız yapabilirsiniz. Bunların zaten örneklerini ayrıca yazacağım. Ancak FreeNAS genel olarak sizin tüm ihtiyaçlarınıza cevap verebilecek düzeydedir. Örneğin ZFS dataset’leri üzerinde snapshot alabilir ve bunları zamanlayabilirsiniz.
FreeNAS sürümleri ile birlikte sürekli yeni özellikler gelmektedir ancak ben genel olarak FreeNAS’ın özelliklerinden kısaca bahsetmek istiyorum.
Yönetim arayüzü özellikleri;
Web tabanlı grafik arayüzü ve isteğe göre SSL encryption
Ortalama 20 adet dil desteği
Web, Console ve SSH erişiminin ayarlanması
Grafik performans raporu
S.M.A.R.T. disk diagnostics
Local sertifika yönetimi ve kendi içine bulunan Certificate Authority role.
Download edilebilir konfigurasyon dosyası
2 factor authentication desteği
Web-based graphical user interface with optional SSL encryption
Alarm desteği ve bunun özelleştirilebilmesi. Yani siz isterseniz bunu email ile raporlayabilirsiniz.
Dosya Sistemi Özellikleri:
Feature Flags (OpenZFS v5000) ve 16 Exabyte’lık teorik depolama sınırına sahip son derece esnek ZFS dosya sistemi. ZFS dosya sistemi özellikleri tamamen yapılandırılabilir.
Compression (lz4 ve gzip dahil),
Tam volume şifreleme (GELI ve AESNI hardware acceleration destekli disk encryption),
Snapshot
Data Deduplication
Kullanıcı kotaları
Fiziksel diskler tamamen taşınabilirdir ve veri kaybı olmadan diğer FreeNAS sunucularına veya OpenZFS’nin uyumlu bir sürümünü destekleyen herhangi bir İşletim Sistemine taşınabilir. Bu oldukça önemli bir özellik. Sadece buradan bence ayrı bir makale konusu çıkar.
Veri güvenilirliği yani Data reliability özellikleri – mirroring / RAID (ZFS RaidZ dahil), güvenilirlik için seçilen verilerin ve meta verilerin birden fazla kopyası ve gerektiğinde tüm sistem sağlama ve arka plan veri onarımı (scrubbing)
Server Güvenilirlik Özellikleri:
Replication ve Failover
Multi version boot – boot menüsü, FreeNAS’ın versiyonunu güncellediğinizde ve güncel versiyonda bir sorun yaşadığınızda tekrar eski versiyonunuza kolay bir şekilde dönebilirsiniz.
UFS2, NTFS, FAT32 ve EXT2 / 3 için disk read ve data import
Kullanıcı / Grup izinleri – Klasik Unix / Linux izinleri ve / veya ACL tabanlı (Microsoft dosya sistemleri için ACL’ler dahil)
Network hizmetleri ve özellikleri
Samba / SMB / CIFS (Microsoft ve diğer ağlar için), AFP (Apple), NFS, iSCSI, FTP / TFTP protokol destekleri
LDAP ve Active Directory desteği
Apple Time Machine ve Microsoft File History desteği
rsync data sync ve replikasyonu (sunucu / client)
Link aggregation ve failover
VLAN
Dynamic DNS Client
Remote syslogd yönlendirme
SNMP izleme
Bakır kablo, fiberoptik kablo, WiFi dahil FreeBSD tarafından desteklenen çok çeşitli ağ donanımı ve ortamları
UPS (Kesintisiz güç kaynağı) desteği
GUI tabanlı yönetim
iozon, netperf, OpenVPN, tmux ve diğer yardımcı programlar
FreeBSD depolarından 20.000’den fazla paket ve bağlantı noktası mevcut ve kurulabilir.
FreeNAS ‘ı peki hangi ortamlarda kullanabilirsiniz? Storage yatırımı yapmak istemiyorsanız ve ileri seviye ZFS ve Linux bilginiz var ise FreeNAS’ı kullanabilirsiniz. Özellikle VMware ortamlarında vSphere HA ve vSphere DRS gibi teknolojileri kullanmak istiyorsanız shared bir datastore’unuzun olması gerekir. Shared Datastore ihtiyaçlarınız isterseniz VSAN ile isterseniz External bir Storage ile isterseniz de fiziksel bir sunucu üzerinde diskleri ekledikten sonra FeeNAS ürününü kurup bir storage haline geetirebilirsiniz. Üstelik FreeNAS üzerinde hem ISCSI hemde Fibre Channel protokollerini kullanabilirsiniz.
https://www.ixsystems.com/blog/openzfs-keeps-your-data-safe
FreeNAS peki güvenilir mi? Buna şöyle cevap vermek istiyorum. FreeNAS’ın sağlamlığı aslında ZFS’den geliyor. ZFS çok sağlam bir dosya sisteim olduğu için FreeNAS’ı güvenli kılıyor. Yazımın başında da belirtitğim gibi FreeNAS’ın gelişmiş bir topluluğu bulunmaktadır. Burada sorularınızı sorailir ve hızlı bir şekilde cevap alabilirsiniz. Eğer isterseniz ücreti olarak support’da alabilirsiniz.
https://www.ixsystems.com/freenas-commercial-support/
Özellikle storage yatımı yapmak istemeyen kişilerin, firmaların hatta hosting firmalarının kullanması gereken bir ürün olduğunu düşünüyorum. VDS Satışı, VPS satışı, Cloud sunucu sataın hosting firmaları için ideal olduğunu düşünüyorum. Değerlendirmenizde fayda var 🙂
Kurulum gereksinimleri oldukça düşük ancak merak edenler aşağıdaki linki inceleyebilir. Zaten kurulum bölümünde ayrıca bunu anlatacağım. FreeNAS Nedir? isimli makalemi burada sonlandırıyorum.
https://www.freenas.org/hardware-requirements/
Umarım faydalı olmuştur.
İyi çalışmalar.

- Structured Query language (SQL) pronounced as "S-Q-L" or sometimes as "See-Quel" is the standard language for dealing with Relational Databases. A relational database defines relationships in the form of tables. NoSQL is a non-relational DMS, that does not require a fixed schema, avoids joins, and is easy to scale. NoSQL database is used for distributed data stores with humongous data storage needs. NoSQL is used for Big data and real-time web apps. For example companies like Twitter, Facebook, Google that collect terabytes of user data every single day.- - #data #programmer #programmerslife #programming #programminglife #programmerrepublic #worldcode #coding #codinglife #webdevelopment #webdeveloper #java #javascript #code #sql #python #perl #php #html #development #software #linux #learntocode #linuxfan #nerd #geek #coders #opensource #computer https://www.instagram.com/p/B5sqrmIgeGt/?igshid=1v7z3yhuah5wl

Raspberry Pi: A music player!
Tumblr media
Since some of you might be unfamiliar with such a device, I will try my best to be as detailed as possible.
Things you will need:
Raspberry Pi 3 (any model will do: A / A+ / B / B+). I used model B (v1.2) for this project. I would recommend you to purchase a case for this device. This is mainly because the mother board is completely exposed and an accidental fall might result in the dismantling or breakage of crucial components. 
A speaker with 3.5 mm headphone jack to stream music from the Pi.
A SD-Card with a minimum storage of 8 GB and preferably class 10 to install the Raspbian firmware.
Either a  PC or Mac to download and install the Raspbian firmware on Pi.
A HDMI cable to display the Raspbian software and configure the set up.
Monitor/TV to display the Raspbian software.
A mouse and USB keyboard to input the commands.
Wi-Fi USB Adapter to have internet access.
Lastly, a USB Sound card to switch the audio output.
Initial setup of Rasberry Pi:
First and foremost, you need to install the Raspbian software to run the Pi. You can find and download the software on this link. Follow the instructions as prompted and it should be pretty straightforward. 
After its successful installation, install Win 32 Disk Imager or a similar software to format the SD card and transfer the .img file downloaded to the SD Card. Then proceed with formatting the SD Card and installation of the software. Insert the SD card in the Pi and connect the Pi to your TV/Monitor via HDMI cable. Lastly, connect the Pi to a wall socket through a charging adapter and the mouse, keyboard through the USB ports on the Pi.
Once the Pi is powered up, it should boot up on its own and if you see a series of commands like pop up, don’t worry! It’s all part of the booting process and shouldn’t take too long.
Configuration of miscellaneous settings:
Start by connecting the Wi-Fi adapter to the Pi through USB ports and click on the blue Wi-Fi logo on the top right corner of the screen (similar to MacOS) and connect to your home network.
Then, set up the sound card by firstly launching LXTerminal on Raspbian. This can be easily found on the top left corner represented by a desktop logo. On LXTerminal, type the following command: aplay -l
If the Raspbian names your USB Sound card upon typing the command above, it means the sound card has been recognized successfully and we can proceed to configure other audio settings. So, as you can see in the picture below, my sound card (‘Sound Blaster Play! 2′) was successfully recognized by the Pi.
Tumblr media
After this, type Alsamixer to change the audio output. Press F6 on your keyboard and switch the audio output from ‘DEFAULT’ to your Sound Card.
Tumblr media
You are almost there. Read on to the final steps:
Its time to test the audio. To do so, hit Esc to exit the Alsamixer mode and return back to the LXTerminal. Then type speaker-test and your speakers should play a tone right away.
And that’s it! You can head over to Rasberry Pi’s browser application and play music which will we played through the speakers. If you wish to stream music using online streaming services, such as Spotify, google play music, sound cloud, etc., you may download Pi MusicBox v0.6 which will automatically detect sound cards connected and stream music.
And that’s it! You have just turned your Rasberry Pi into a streaming music player! Wasn’t this easy? I am sure you would be proud of your invention now!! 
------------------------------------------------------------------------------------------
There are endless project one could image with a Raspberry Pi and its opensource nature uplifts its ultimate potential. As such I have also done projects such as the automatic plant watering system (Pic 1 below) and the integrated sensor wireless communication through the XBee interface (Pic 2 below). So now I need not have to worry about my plants’ health whenever I travel for vacation and the wireless data transmission has taught me so much about electronic interfaces and transmission signals! Stay turned to my posts as I will write on them soon.

1Flac FLAC To MP3 Converter
A utility to convert a Flac library to MP3, Opus or Ogg Vorbis format. Lossless compression is benign in its impact on the music. It's akin to LHA or WinZip laptop data crunchers in packing the data extra effectively on the disk, but the knowledge you read out are the identical as went in. The primary difference between lossless compression for laptop knowledge and for audio is that the latter permits random entry inside the file. (In the event you needed to wait to unZip the complete 400MB file of a CD's content earlier than you could play it, you'd rapidly abandon the whole concept.) You will get discount in file measurement to forty-60% of the unique with lossless compression—the efficiency of assorted lossless codecs is in contrast right here and flac to mpc converter online no limit here —but that increases the capability of a 4GB iPod to solely 300 songs, or 20 CDs' worth of music. Extra compression is important. iConverter is a free cell app for iPhone and iPad It has a good selection of audio input and output file varieties in addition to its exhaustive record of supported doc and audio-transcoder.com video file types. This conversion app works seamlessly with the File app and permits you to drag and drop recordsdata in break up-display screen tasks. iConverter has a easy audio editing instrument and helps the most popular compression codecs to assist ship giant folders via electronic mail or textual content. Apple Lossless, also known as ALAC (Apple Lossless Audio Codec), or ALE (Apple Lossless Encoder) is an audio codec developed by Apple Inc. for lossless data compression of digital music. In keeping with Apple, audio recordsdata compressed with ALAC will dissipate "about half the cupboard space" that the uncompressed information would require. ALAC might be performed on all current iPods, iPhones and iPads, and will play on QuickTime 6.5.1 and iTunes 4.5 and on their later model. Free Lossless Audio Codec (FLAC) is a file format for lossless audio information compression. Being lossless, FLAC doesn't take away data from the audio stream, as lossy compression formats comparable to MP3, AAC, and Vorbis do. FLAC's primary writer is Josh Coalson. FLAC reduces bandwidth and storage necessities without sacrificing the integrity of the audio source. A digital audio recording (akin to a CD observe) encoded to FLAC might be decompressed into an similar copy of the audio data. Audio sources encoded to FLAC are typically contracted forty to 50 percent (forty six% in line with their very own comparison). FLAC is suitable for on a regular basis audio playback and archival, with support for tagging, cowl art and fast searching for. FLAC's free and open source royalty-free nature makes it well-supported by many software program applications, but FLAC playback help in transportable audio gadgets and dedicated audio systems is restricted at the moment.
FlacSquisher does save the original FLACs. You specify the listing that contains your Flacs, and the directory you want the transformed files to go. It converts the information while preserving the originals intact. In my case, it implies that if a new model of the encoder is launched that provides better high quality on the identical bitrate, I can just delete my lossy folder, hit "Encode", and walk away. Just like Switch, Xilisoft lets you extract audio from video recordsdata. A few of the supported video file formats include MP4, MOV, M4V, MKV, AVC, AVI, WMV, among others. This converter is compatible with 18 completely different file codecs and is able to changing information to sixteen totally different output codecs. Xilisoft is without doubt one of the most versatile audio converter software program in our lineup. FileZigZag is another free online audio converter that may assist you convert FLAC audio to MP3 and other formats totally free. Navigate to the positioning, add the audio file or URL, set the output format and then convert. But not like Zamzar, it can solely convert one file each time. Its advantage over Zamzar is it helps more enter and output codecs and the supply file is limited to a hundred and eighty MB. Flac to Mp3 - free on-line application converts audio information withflac extension to compressed Mp3 file format. Flac is the short kind for Free Lossless Audio Codec and is a high quality audio format. Unlike Mp3, flac is a lossless audio format that means that there isn't a loss in information like Mp3. One of the main advantages of Flac is that it's patent free and has a opensource implementation as effectively. Chances are you'll need to convert flac to mp3 for numerous reasons. One the explanations could be to decrease file size or must play on any widespread audio participant. Our flac to mp3 converter involves your rescue and may convert any flac file to Mp3 audio file. Our decoders and encoders are special in sustaining the very best quality vs file dimension balance.Freemake Audio Converter gives you with a number of choices for managing music recordsdata and changing them to whatever format you desire. The additional benefit with this instrument is that it will possibly course of and convert multiple information on the identical time and performs multitasking as nicely. However you'll want to buy the Infinite Pack to convert audio recordsdata that are longer than three minutes.Pazera FLAC to MP3 Converter (version 1.1) has a file measurement of eight.57 MB and is obtainable for download from our website. Simply click on the inexperienced Download button above to start out. Till now the program was downloaded 124 times. We already checked that the obtain link to be secure, nonetheless to your own safety we suggest that you simply scan the downloaded software program with your antivirus.
