Cutter is "A Qt and C++ GUI for radare2". There are more alternatives to IDA Pro. Hopper Disassembler is one. Binary Ninja (binja) is another. Here is an independent review of Binary Ninja: https://www.trailofbits.com/research-and-development/binja/ Here is the project itself: https://binary.ninja/ I happen to know most of the people involved in Binary Ninja.

Radare, in my opinion, is mostly lacking on the user-experience sides. IDA is easier to pick-up and use. Also, I feel Radare's decompilers don't fare as-well as Hex-Rays. I equate this to Windbg - your best Windows debugger, which unfortunately is relatively tough to pick up (I'd argue, mostly due to poor UI choices). Forgoing that, Radare is absolutely packing.
I've moved on to reverse most of my projects with Radare. I'm still missing a handful of small features/plugins from IDA, but it's not a big issue.

If you're not worried about the ethical implications, Autodesk doesn't verify student info for their free student licenses.
Fusion 360 is free for hobbiests. Not just students. If I _wanted_ to be unethical, I could surely get anything I wanted. I want to buy something and be in good standing to use it to perhaps build something to sell.
Fusion is a whole other ball of wax. I was referring to the rest of the Autodesk suite. You can certainly find cracked versions of whatever, but (ab)using the student licensing will at least be some insurance against malware.
The way I look at it (and I'm obviously not a representative of Autodesk in any way, shape, or form): if it's making you money, pay for it. If it's not, don't. If you pirate it to learn how to use it, that's one thing. If you wanted to start selling whatever you're designing that would be the time to pay.
Autodesk, like Adobe, is making a huge push towards subscription licensing. I detest that stuff, but it's at least less of a hit initially unlike IDA.
I've been watching the ecosystem of radare2 GUIs for a while now. I've loved IDA for its long-standing support of numerous architectures, as well as its built-in interpreter for running Python/IDC scripts with ease, however the price is nearly inhibitive for the average student or weekend hacker. IMO, the one major reason that radare isn't as widely adopted in the RE industry is simply because of a lack of GUIs that…
I think one of the most difficult things for me with r2 is that there is no stable API and minimal detection for the internal stuff. If you're merely working on top of well supported architectures (e.g. arm, x86) you're probably going to do just fine with the "pipe" interface.
However, for more advanced features (e.g. new architectures) it's less fun. For instance, when the python bindings break the general response is "fix it yourself and submit a pull request because we don't want to maintain python bindings". Which would be great if the APIs weren't a constantly moving target.
The lack of clear documentation hurts the APIs themselves as it's not necessarily clear which parts are deprecated and which represent best practices. Hopefully with the growing community we'll see some of the cruft get cleaned up.

Reverse engineering has been a constant interest for me but I've never managed to get it to "click" for me. I don't particularly need the skill, but it's one I'd like to have (at least to the extent of being able to do simple crackmes).
It's a tricky art. It's helpful to learn some of the basics such as how variables are passed to a function on the stack for x86 or as registers with x64. Beyond that it takes practice. Things that have helped me are writing c code and dissassembling it, stepping through code with GDB and working on crackmes and CTFs. For radare2 in particular, this tutorial was helpful: https://leotindall.com/tutorial/an-intro-to-x86…
Another thing I like to do is to rewrite complex parts of the disassembly in pseudo-C (though radare has an option to do this automatically), which makes the overall logic easier to see (and is, of course, the entire point of decompilers like Hex-Rays).

My earliest exposure to computers was the ZX Spectrum, an 8-bit home-computer from the 80s, which was insanely populare in the UK. Having few games, and little budget for more, most of the kids around would swap home-copied games. I used to have fun removing protection, or hacking the games for infinite lives. At the time I was 12-15 and it was very much a case of trial or error. Assuming a game started with 3 lives…
I highly recommend anyone who's interested (particularly people who don't remember a pre-Google, pre-Facebook internet) in bold (and crazy) ideas about technology reading his work.
Edit: I suppose many if not most of the essays aren't strictly "pre-Google" but they are from its much earlier days when it was a very different service.

Currently there are countless things we can do with the applications in our smart Android mobile, from a fun time with games to productivity applications.In this way of diverse is the planet of the apps of this operating system, and is that even there are applicationstoearnsomeextra money using for a few minutes a day your phone or tablet Android.Precisamente, in this article I come to tellabout one of them, it is Whaff, which according to my experience I can catalog it as a the best applications ofthis type,orperhaps the best.
Whaff Rewards has many reasons to consider it the best application of this item, since the amounts of money that are earned with it are considerably higher in comparison to others, in addition there are a lot more of offers that we can complete and there are offersforwhichIwasto pay for day after day that we hold installed a certain application. In addition to that, we will also be given a certain amount to use Whaff daily in order to increase our balance.And what about the prizes, we can charge our money through PayPal or through different Giftcards or different gift cards platforms such as Google GooglePlayStore, Amazon, Steam, Play Station, Minecraft, Blizzard, among others. And something that also offers us Whaff, is that just by registering gives us a bonus of 20 cents, but if that is not enough, after registering you can enter the next code that I will leave now, which will give you 30centavos additional , soyou'll start at Whaff with 50 cents in your balance.Excellent, right ??
Welcome code for $0.30 cents (enter without quotes): "JR40691" you know that you can get the money using only Android is whaff rewards that provides an application for mobile devices called whaff rewards that can use to make money without capital.What do we need?to use the application whaff rewards, we just need:
1. Android 2 Facebook 3 internet
How it works: Please note this first Invitation Code ( JR40691 ) because if you do not enter this Code ( JR40691 ) you will not have $0.30 Here's how to
1. Open Playstore 2. Search >> WHAFF Rewards Or WHAFF Locker 3. Install the Application & Open the WHAFF Application 4. Login With Your Facebook After Login Then Wait Until it says ENTER INVITATION CODE Then Enter This Code [ JR40691 ] And You Will Get $0.30 Pretty Right But If You Do not Enter Your Code Will Not Get $0.30 Your Will Get$0.00 Just paste this code [ JR40691 ] let me not forget 5. Install & Play Apps Or Games Available On Pick Premium Or play videos 6. And See Dollar $ Growing
And this is as follows: how to withdraw Dollar from WHAFF to your Bank
8.Click the top left corner and the screen will display payment / payout options
9. Choose $11.5 Because $11.5 is the minimum amount that can be taken for a Paypal Account
10. If already Enter your Paypal Email And click "Request"
11. Dollar will be sent to Paypal account You For 3 Working Days
NOTE: "WHAFF Rewards" Requires Active Users We Are Applying You To Keep On Using And Running This "WHAFF Rewards" For You To Get Paid Dollars But If You Are Inactive Or Removing This Application You Will Never Get Paid So Install app or game App In this WHAFFRewards And Play For 3 Minutes

> There are more alternatives to IDA Pro. Hopper Disassembler is one. Binary Ninja (binja) is another. Sure, but radare2 is open source which cuts both ways I suppose. IDA feels significantly more polished than r2, but I've had fun implementing a not-so-common-anymore architecture as a set of r2 plugins. There's also the free version of IDA (x86 only though).
