hi there! i’m a high schooler and i’m seriously considering majoring in computer science when the time comes. do you think you could maybe talk a little bit about what it’s like studying comp sci? if you can. i hope you’re having a great day

hope you’re having a great day too!

What my first year of studying computer science was like

obligatory preface that courses differ between universities and colleges. i study in australia.

The biggest challenge I faced per se going into comp sci was how nothing I did at school prepared me for it. The kind of content I’ve learnt wasn’t similiar to school and the assignments have been very different. No analytical essays and scientific reports for me (there has been essays and reports tho). In my school IT class I learnt basic HTML and CSS which was the only programming knowledge I went into comp sci with. (Id also gotten pretty far on khan academy’s JavaScript course in like year ten but I’ve forgotten all of that now lol).

I have four units a semester and have completed my first year (of 3, although I’m taking less units this year so I’ll finish in 3.5 years).

What I actually did in my first year:

Semester 1 (pre-major picking, two of these were for the other major option)

Learnt general computer hardware and how it functions. The assignment was using a raspberry pi to do something that used hardware (the pi), software (basic code) and the internet (I used twitter). My project is on Twitter at SunsetIFB102

Group project app design stages. Like drawing the layouts, getting feedback, then digital sketches then semi fancy looking sketches (not comp sci major)

Python! I really liked this. Taught the basics of python and in general programming. It was kind of intimidating how many people had coded before so I had to focus on ignoring them and learning for myself. Also really salty I was 1% off a high distinction for the whole unit AGH

Databases and SQL. This would’ve been a useful unit if the lecturer was, how do I put this kindly, good at his job. (Not comp sci major, although definitely use databases later on)

Semester two (all comp sci major)

C# , basics of object oriented programming principles. Which is a fancy way of saying it taught how you should write your code so it’s laid out effectively.

C, how to program microprocessors. Basically how to program hardware machines. C is mostly used for machines like ATMs, a fridge perhaps, probably a roomba and other single purpose kind of things. Also from this I can program arduinos and read arduino code easier since arduino code is a C/C++ hybrid. (This and the previous unit had high fail rates and were honestly Tough)

Information security (apart of network security minor) This unit talked about processes of protecting information in organisations and on a single person level. Basics of cryptography was discussed and hashes and how ways information is kept secure when transferring between objects (like over the internet)

Computation mathematics (apart of intelligent systems minor). This was a weird unit to me and was mostly math majors. It taught all these different equations which allow you to make approximations. Honestly confused how it’s used for computers but we learnt MATLAB and it’s a pre requisite for an intro to robotics unit I’m taking this year :)

So yeah, that’s an account of what I actually studied. Reading over it it seems way more impressive than it probably was. Computer science isn’t easy (well, unless you want to scrape a pass each time) but it isn’t horribly difficult. It’s how different it is to high school work that can trip you up. I can’t make aesthetic studyblr notes on paper because its all on my computer and can’t turn it off when studying because I need it.

My assignments are typically big coding projects, exams (multiple choice if a coding unit) and essays if it deals with theory (like info sec did).

This coming semester I’m learning Java and GUI’s (graphical user interfaces), JavaScript and HTML and whatever else for web applications, and discrete maths which seems to be for notation used later on... it looks very strange.

Hope this helps! If you have any more questions feel free to DM me!

Also if anyone else wants to add their experiences, feel free to reblog with your tips.

something like vrf to ensure segmentation of SSID/VLANS

Manage all this via salt.. and look into dbus remote send

move to WPA3 or Radius or something more secure

Do I

local cluster/bind9 <--> local dnsmasq

local cluster/bind isc-dhcp-server <--> local dnsmasq

Why, bind9 able to look up root no fowarder required, and local entries for windows ect, but dnsmasq for fast caching .. is it overkill, bind9 is supposed to cache too in ram, but we want this highly available and fast

Same for dhcp fast/redundancy

Daily Crunch: Google backs India’s Reliance Jio

Reliance Jio continues to add billions of dollars to its bank account, Apple scores a tax victory in Europe and researchers test a system for undersea Wi-Fi (with lasers!). Here’s your Daily Crunch for July 15, 2020.

Google invests $4.5 billion in India’s Reliance Jio Platforms

Another giant tech company has invested in India’s largest telecom, following Facebook’s investment a couple of months ago. Reliance Jio has raised about $20.2 billion in the past four months — more than the entire Indian startup ecosystem raised last year. Google and Reliance Jio will also be working together to develop low-cost Android smartphones.

“Getting technology into the hands of more people is a big part of Google’s mission,” said Google CEO Sundar Pichai. “Together we are excited to rethink, from the ground up, how millions of users in India can become owners of smartphones.”

The tech giants

Apple and Ireland win appeal against the European Commission’s $15 billion tax ruling — Four years ago, the European Commission said that Ireland had failed to collect around $15 billion in taxes from Apple, but the European Court of Justice has annulled that decision.

Zoom introduces all-in-one home communications appliance for $599 — The new Zoom for Home – DTEN ME includes a large tablet with three wide-angle cameras and eight microphones.

Snap debuts a 13-week remote program to help developers create deeper Snap Kit integrations — Yellow Collabs is an expansion of Snap’s Yellow division, which previously consisted only of a startup accelerator.

Startups, funding and venture capital

Fraud detection startup Ravelin secures $20M Series C — The startup’s goal is to use machine learning to improve the fraud detection process, giving merchants more confidence in accepting customers and transactions.

Lemonade launches pet insurance — This is Lemonade’s first new vertical since it launched renters and homeowners insurance in 2016.

Substack launches Defender, a program offering legal support to independent writers — The newsletter platform said it will determine who to support on a case-by-case basis, covering up to $1 million in legal fees (or even more in “exceptional cases”).

Advice and analysis from Extra Crunch

How to do remote work right, from the teams that know it best — Tips from Zapier CEO Wade Foster, FlexJobs CEO Sara Sutton, Twilio CEO Jeff Lawson and others.

Emergence’s Jason Green thinks some of the tech backlash is justified, but the B2B opportunities still outweigh the challenges — The VC also described the death of George Floyd as “a profound moment and shift for me personally.”

Generative algorithms are redefining the intersection of software and music — Generative algorithms and growing amounts of computing power are increasingly changing what computers can do with music today.

(Reminder: Extra Crunch is our subscription membership program, which aims to democratize information about startups. You can sign up here.)

Everything else

Researchers develop laser-based underwater Wi-Fi system for sub-sea data networks — The researchers from King Abdullah University of Science and Technology managed to use their system to do Skype calls and move files back and forth, but they also burned out the Raspberry Pi using lasers that overwhelmed its capabilities.

Nissan stakes its EV future on the 300-mile-range Ariya crossover — The Ariya is an all-electric SUV with a starting price of $40,000.

Added the ByteStars networking instructions for the ByteStars preconfigured raspberry pi. Boots out of the box to the 3.5in touch screen monitor. Then connect to it via remote desktop...neat. See here: https://www.ebay.com/itm/202585866726

Start the Terminal program: >_

then type:

sudo raspi-config

Press return and select change “User Password” use a strong password if you’re going to be accessing your raspberry pi remotely - see the Network/Internet Connectivity section. Enable SSH and VNC. The default user name is: pi and password is: raspberry.

NETWORK/INTERNET CONNECTIVITY/Remote Desktop/SSH and VNC

Network connection with Ethernet: The raspberry pi Ethernet and Wi-Fi port is set to auto: Connect your wired Ethernet network cable to the raspberry pi's Ethernet port or connect to your Wi-Fi. You should now have an internet connection.

Once connected to your network with either the Ethernet or Wi-Fi connection; and you know the IP address that was assigned to the raspberry pi by your equipment: mouse over the network icons or type "ifconfig" in the terminal program to learn your IP address.

For a Remote Desktop Connection (Graphical) There are 2 ways. VNC and Remote Desktop (RDP) Some Differences/Considerations RDP is a security concern if using from outside of your network. Only use on your local network. VNC uses encryption and is more secure. VNC can be used to access your raspberry pi from outside your local network. For example, from office to home. Download the VNC client from https://www.realvnc.com/en/connect/download/viewer/: RDP can display the raspberry pi at better resolutions and creates a non mirrored screen of the 3.5 or other built-in screen. VNC displays the raspberry pi at the built-in display resolution and is mirrored to the built-in screen. VNC can do file transfers with built-in on screen controls.

On Windows/PC, use the built-in program: Remote Desktop Connection From the Windows start button: Start / Accessories / Remote Desktop Connection. the Remote Desktop Connection program will start. Type the IP address of the raspberry pi and click OK. A raspberry pi login screen will then display. Login with your User Name and Password. Neat, your desktop computer now displays your raspberry pi and so does the 3.5 display. VNC connection.

Run the VNC program and start a new connection using the raspberry pi IP address. Connect and login.

To connect to your new raspberry pi device with SSH.

Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Typical applications include remote command-line login and remote command execution, but any network service can be secured with SSH. Basically, it will allow a secure remote computer a command prompt connection to the raspberry pi. For windows download the program Putty at https://www.putty.org/ Install the free and very small 2.8mb program. Run Putty. Enter the raspberry pi IP address. A command prompt will display. Login with your User Name and Password. Neat, your desktop computer now displays a command prompt that affects the raspberry pi.

Troubleshooting connection tip. Make sure both the raspberry pi and the desktop/laptop computer are on the same network. On widows desktop, open cmd (command line terminal) and type ipconfig to see your network assigned ip address. On MAC/Linux, run the terminal program and type ifconfig. Both the computer IP address should (for example look like this: 192.168.?.?, or 10.10.?.?. The 1st ? should be the same, 2nd ? should be unique.

For outside connections, for example, from your office computer to the raspberry pi at home. You will need to configure your router for port forwarding - Another topic.

3.5 display setup (need internet connection)

// Run in terminal. 1 at a time. Or automate with a batch file.

sudo rm -rf LCD-show

git clone https://github.com/goodtft/LCD-show.git

chmod -R 755 LCD-show

cd LCD-show/

sudo ./LCD35-show

reboot //

// If you want revert back to the HDMI port. Open the terminal and type commands 1at a time to get back.

chmod -R 755 LCD-show

cd LCD-show/

sudo ./LCD-hdmi

reboot

How to Use the IonBloc SDK

Srinidhi Murthy

What is Block Chain?

A blockchain – originally block chain – is a distributed database that is used to maintain a continuously growing list of records, called blocks. Each block contains a timestamp and a link to a previous block. A blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. By design, blockchains are inherently resistant to modification of the data. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks and a collusion of the network majority. Functionally, a blockchain can serve as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The ledger itself can also be programmed to trigger transactions automatically."

Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain. This makes blockchains potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, and documenting provenance.

IonBloc

IonBloc Data flow and usage

IonBloc is our version of Open source Ethereum Blockchain network that can be setup as a public production implementation or a private test implementation depending on client needs.

In an IoT network, the blockchain can keep an immutable record of the history of smart devices. This feature enables the autonomous functioning of smart devices without the need for centralized authority. Thus, blockchain opens the door to a series of IoT scenarios that were remarkably difficult, or even impossible to implement without it.

By leveraging blockchain, IoT solutions can enable secure, trust less messaging between devices in an IoT network. In this model, the blockchain will treat message exchanges between devices like financial transactions in a Bitcoin network. To enable message exchanges, devices will leverage smart contracts which then model the agreement between the two parties.

Using blockchain will enable true autonomous smart devices that can exchange data, or even execute financial transactions, without the need of a centralized broker. This type of autonomy is possible because the nodes in the blockchain network will verify the validity of the transaction without relying on a centralized authority.

Installation:

The IonBloc SDK allows for a seamless connection to our private Blockchain. Here’s how you can do it. You need to have a Raspberry PI 3 with a 16GB SD card and running the latest Raspbian OS. Also, you need to have a stable high speed Internet connection (500 kbps at a minimum)

Download the Zip file from Github or execute a git clone command on our repository.

Extract and Install the SDK using the Installation script.

Some of the necessary support libraries are installed and you are taken to a GETH console.

Once you are in the GETH console,

Create a new account. (Noted down the password)

Provide our Admin Enode address and Pair

That’s it you are connected to our private Block Chain.

Now the possibilities are endless, but to get you started we have given a sample code and procedure to create contracts to blink an LED connected to a GPIO pin on the R-PI.

You can create contracts which have more features, which can read sensors, turn on actuators, monitor sensors etc. IonBloc SDK is just the starting point … the tip of the iceberg. Some of the more advanced use cases can be found in

IonBloc SDK is just the starting point … the tip of the iceberg. Some of the more advanced use cases can be found in

Industrial and manufacturing for improving monitoring and efficient “Just in Time” (JIT) processes.

Connected and Driverless vehicles where every vehicle becomes a node and there can be an efficient vehicle to vehicle communication.

Public infrastructure and smart cities: Smart devices are already being used to track the health of bridges, roads, power grids etc. Blockchains can be used to interconnect these to share efficiencies and to conduct maintenance, forecast usage trends for power usage, pollution etc.

We have given a limited set of features to create a working POC that can be later developed into fully fledged modules. There are many more features that can be added as a part of customization for specific requirements. We can do a lot more with IonBloc (some of the features are present in the data flow diagram).

Please feel free to contact us at the mailto:[email protected] for any information or customization.

Raspberry Pi’s $50 camera opens the door for awesome DIY photography projects

The Raspberry Pi camera has a big enough sensor to capture higher-quality images. (Raspberry Pi/)

Even if you don’t fancy yourself a coder or maker, Raspberry Pi’s tiny, dirt cheap computers offer a great entry point into that world. Just $35 will get you the essential guts for a fully working computer (you supply the mouse, keyboard, monitor, and power supply). Now, the company has announced a high-quality camera module that works with its pint-sized computers. It has a 12-megapixel resolution, a mount for interchangeable lenses, and an enticing $50 price tag.

As the price suggests, this isn’t meant for frankensteining your own DSLR, but rather for cool DIY projects. The Official Raspberry Pi Camera Guide (which is available as a free PDF), offers up ideas like building your own security system, setting up a camera trap that automatically captures images of animals as they walk by in the wild, or programming epic time lapses you can export as high-res movies. The projects take varying amounts of experience and know-how, but there’s a vast network of Raspberry Pi experts with tips to share out there on the web, which is part of what makes it such a popular platform for makers in the first place.

The new Raspberry Pi High Quality Camera replaces the old Camera Module that debuted back in 2013 and represents a serious upgrade in terms of image quality. It’s built around a Sony IMX477 image sensor, which is intended for cameras like camcorders, and is roughly the size of the sensors you’d find in a smartphone camera. So, it won’t blow your DSLR out of the water, but its 12-megapixel resolution should be plenty for most applications, unless you’re hoping to make large prints.

The most interesting part, however, is the interchangeable camera mount sitting in front of the sensor. It accepts C and CS-mount lenses, which are typically small and useful for things like security cameras that don’t need absurdly high resolution.

Raspberry Pi currently offers a pair of native lenses for the camera, including a 6mm lens for $25 and a 16mm lens for $50. If you’re familiar with lens terminology, those small focal length numbers suggest extremely wide-angle lenses—6mm typically falls well into fisheye territory. But, because the sensor is relatively small, it lessens the wide-angle effect rather considerably.

A comparison shows the difference between the older camera module and the new high-quality hardware. (Raspberry Pi /)

While you can pick up plenty of old C-mount lenses on the secondary market, you can also pick up lens adapters to convert the camera to work with modern glass. So, if you wanted to get an adapter and stick a $2,000 professional zoom lens on there, you could. It would probably earn you lots of likes on Instagram. Just know that, because of the sensor’s relatively small size, images from any attached lens will look roughly 5.6-times more zoomed in than they would on a full-frame DSLR. So, that relatively typical 200mm zoom lens will suddenly feel like a small telescope.

Compared to the old camera module, results from the new hardware look vastly improved. And with this low of a price point, it seems like a great way to get into camera hardware hacking without having to literally hack apart old pieces of gear.
