It’s that time of the semester, folks.

I’m:

just waiting for it to end;

losing sight of the finish line;

feeling like I can’t do life anymore.

I’ve been burned out for years now. (Fellow former “gifted” kids, a show of hands please.) I really love note-taking—Mine are usually very compact but informative enough that I never have to touch other course materials again (a highly recommended strategy). But since I procrastinate a lot (what with the added fatigue of online classes), I also have a habit of abandoning entire study endeavours (sometimes entire semesters) because I don’t have enough time to put together the “best” notes.

But today I attended an online productivity workshop by UTSA (the turnout was HUGE) and was blown away by the overwhelming support. I used to go to so many of these on campus. I’ve missed it.

(I’ve randomly pasted my notes onto a couple of templates, in case they gives you hope too.)

I signed into another online talk hosted by Cornell. It put some really great career-/research-related ideas into my head.

The Linear Algebra exam I’ve lost sleep over was alright too.

Today was good. Amazingly, it also marks two months of me BuJoing (semi-) regularly.

The planner revolution never interested me (the infinite mixed-media scrapbooking possibilities give me anxiety), but the moment I first laid my eyes on a doodled-over dot-grid notebook, I was enchanted.

The Bullet Journal Method by Ryder Carroll was my first self-help book; it took my breath away with its combination of impeccable science and gentle empathy.

Last month, I used oh no nina's simplistic setup, and in combination with traditional BuJo bullets, it saved my life through a WILD sh*tstorm I never saw coming.

After over a year, I’ve found what works for me.

I am now SIGNIFICANTLY more mindful of how I divide my time.

And when I suddenly once again find myself buried under weeks of leftover work, I know how to dust myself off, reorganize my abandoned week-old bullets, and begin ticking them off again.

My resolutions after today:

Attend more online talks;

Set time aside a couple days per week for even my asynchronous classes;

Fix my sleep schedule.

Final Evaluation

My initial aim for this project was to recreate my own cabinet of curiosities by making and acquiring objects that when assembled would have a certain affect on the viewer of which I wanted to be curiosity. I wanted people to open their mind to unconventional art and try to understand it. I wanted people to wonder why it existed, who made it, what the story is behind it is. When I chose my title of ‘The Cabinet Of Curiosities’ I discovered that, without realizing before, that I had my own collections of curious objects, and so with identifying personally with this subject I didn’t find that I had any problems in the creative thinking department. This however I think did have a role to play in some of the problems I struck along the way.

A problem throughout the project was starting something and then not completing it, this nevertheless did contribute to my experimentation along the way but it just meant that I felt uncertain at a few point during this project. On the other hand to this, when I started something that I was certain in I saw what I had imagined it to be come alive, and having my ideas come to life in the exact same way I planned them in my head is a first for me and something that before the fmp I struggled with. A piece which demonstrates this is the crescent moon piece of which I knew I wanted to have people collaged onto it. I also think this piece stands out in the collection as usually with other peoples cabinets, its often a range of objects they find rather than what they make. But referring back to my project proposal, it was part of my initial plan to make my own objects that maybe one day will end up in a charity shop and someone may add it to their own collection and so it then becomes a found object rather than a handmade one.

My goal in the beginning was to create loads of little object that would fill a whole wall but as I began my thorough research into this area I found that not everything was randomly made. Objects in famous collections, especially seen in the Pitt Rivers Museum and the Derby Museum and Art Gallery, were taken from other cultures from around the world or had links to folklore or mythology or medicine etc, it was then I began making things that derived from a meaning/purpose. An example would be my Moon/Hare piece which I made based upon the information I read that stated, that in a folklore tail a hare supposedly lives upon the moon and if ever sighted would bring you luck. Although no one would ever know this unless they search for it, I think it gave me a boost with my work as once I felt like I was making something with a purpose, it came more naturally to me rather than thinking on the spot and making as I go. This particular piece also happens to be my favorite piece because I think it represents my ‘quirkiness’ perfectly and although it wasn’t a complex thing to make, it still makes my work my own.

Once I came to presenting my work I knew that it was this process that would make or break my project as with most cabinets of curiosities, the visual impact is perhaps the most important part. Once I had divided my objects and placed them where I wanted them I felt like something was missing and it was then that I decided at the last minute that I wanted to add flowers/weeds/sticks etc, to really sell the ‘antique collection’ look I wanted, and I think it was this that I think really made me happy with my final outcome. I also like the idea that throughout the exhibition the flowers/weeds naturally die and shrivel which I think is a really good outcome for a last minute decision.

Overall, I am very happy with the outcome as especially towards the last few weeks I started to doubt myself. I think this is down to the fact that although I had brought in plenty of objects, seeing what I had made felt a bit random and not really like other famous collections. However, when seeing what I had made alongside all the other things I had accumulated over the last few months, it really boosted my confidence and seeing it finished really made me proud of myself. Before this final project I had problems with finishing my work to the standards I had set myself but this time I think I created exactly what I wanted to see. I don’t think my collection is anything like the famous collections you see online but I think that a collection should also reflect the artist who made it and I think mine matches me perfectly.

Writing Tag Game

I was tagged by @vraberika literally just now holy cheese and puddings I am somewhat remembered and wow I was pleasantly surprised.

Seriously thank you so much/// You’re? The actual sweetest?

What is your total word count on AO3?

113153

Since? October of 2015 wow I write slowww

But to be fair I have tons of abandoned wips haha.

Pretty sure a huge chunk of it was from the DEH series I completed a while ago.

How often do you write?

When I get the time to do it. Between school and the translations I do on another site, there isn’t nearly enough spare time for writing than I’d like. Then there’s the writers’ blocks and those are always fun amiright

I really really wish I can write more though... at least finish up my previous wips hnggggg I’m very very sorry I’ve been so inactive but I just don’t have the time and effort to manage everything.

Do you have a routine for writing?

Not really? I just go with the flow mostly. Idk what you mean by “rountine”... I’m pretty...un-routinely.

What are your favorite kinks/tropes/pairing?

Enemies to friends/lovers probably. I don’t know why it’s always intrigued me!! I also love fantasy AUs <3

As for pairings... I have a bunch? But for the Ina fandom it’s afufubu (no surprise there)

Do you have a favorite fic of yours?

I automatically hate every fic I write because I’m never really “satisfied” with them. I mean yeah they probably took days, weeks, even months of planning and rewriting, but there’s always room for improvement, because I’m obviously not the best writer. I always get this feeling aw darn I ruined that idea. I bet [insert random fanfic writer] could do amazing things with this idea but I had to sabotage it.

As you can see I don’t have the highest self-esteem.

But if we’re really talking here.....

Probably either Freshly Drugged and Ready to be Slaughtered, which I wrote for the Haikyuu fandom, because I got to explore my version of the characters when put under the harsh environments that is the Hunger Games (and also I love writing angst AHAHA)

Or Tips to Teen Angst, Friendship Maintenance, and the Art of Matchmaking, which I wrote for the Dear Evan Hansen fandom. I got to write a bunch of fun texty dialogue. (I made them swear a lot whoops) I don’t know I really enjoyed the pacing of this one.

If we’re talking about the Ina fandom though- I’ve actually written a bunch of fics I never posted online. My favorite has got to be the one titled 吹雪（敦也）on my blog, which literally just means Fubuki (Atsuya). I like to sound sophisticated. Fight me.

I really love writing that one because I got the explore the dynamic between Aphrodi and Atsuya, who have never actually interacted onscreen!! It’s just so interesting!!! (Hi I’m a professional rarepair shipper. Romantic/platonic/rivalry we have it all!)

Your fic with the most kudos?

I don’t know what to say here because I’ve literally never put any of my Ina Eleven fics on AO3........ pysch!

How Do Friendships Work Again (Dear Evan Hansen), with 166 kudos. Which is strange. Because yes, I spent a lot of time and thought on that fic, it’s really not one I struggled with. It was not one of those ideas that I carry with me everywhere, it was not one of those stories that I spend forever revising and replanning. It was quick, it was written on a whim. I still cherish it very very much, but it just comes to show how the popularity of certain fandoms affect the stories’ feedback. I could spend grand lengths of time and devotion to this one, well thought-out fanfic I wrote of a rarepair, and get completely dismissed. I could spend a few hours to write this short, sweet fluff piece that doesn’t really hold much lore or depth, and get a bunch of attention just because people like that particular pairing.

Anything you don’t like about your writing?

Everything lol.

I have so much to work on.... The flow, the pacing, the vocabulary, the list goes on and on and on.

The only thing I can write is dialogue, and it’s not like I can make my characters talk forever.

Or maybe I could.

I should experiment it sometime.

Now something you do like about your writing?

Oops already answered that one above.

The dialogue, because I am a certified Trash-TalkerTM So I’m constantly applying that skill onto the sassier characters.

I mean people have told me that I write really fun dialogue and honestly I trust their tastes over mine.

Imma tag @ozrockbitway I guess? If you’d like? *hides behind a pillow*

I’m a huge.... outsider......... actually............because I’m always...........disappearing randomly....................and I apologize for that..............................I’malsoreallybadatmakingfriendssotheresthathaha

I’ll... try to be more active in the fandom but honestly? No promises. I love Ina Eleven because it made up a huge part of my early cringe teen years, and I always will love Ina Eleven, but I have school, I have other fandoms, I have other projects I’m working on and I don’t know how to divide my time fairly anymore. Especially recently I’ve been pushing myself to update things that I’m not really feeling, but because my followers are really looking forward to them, I update anyway. Not the healthiest, I know. I have no idea what I’m doing with my life anymore.

I honestly have a lot I’d like to say about the new Ina Eleven series, but I haven’t found the time to put them into words yet. I’d say keep a lookout if you’re interested in my piece of mind.

Thank you all so much for the support you’ve shown me in the past. You are all amazing, no matter what you might think or what others might say, every single one of you!! I hope you all have a wonderful day!!! And oh boy how in the world did this turn into a self-reflection post I thought this was a light and happy tag game.

#tag game #thank you guys so very very much when the hell am i coming out of hiatus tho #on a seperate note #broadway musicals are amazing people!! seriously you will not be disappointed

Fast Accurate Network Intrusion Detection System

Intrusion Detection System (IDS) is a valuable tool for the defense-in-depth of computer networks. However, an Intrusion detection system faces a number of challenges. One of the important challenge is that, the input data to be classified is in a high dimension feature space. In this paper, we effectively proposed PSO-DT intrusion detection system. Where, Particle Swarm Optimization (PSO) is used as a feature selection algorithm to maximize the C4.5 Decision Tree classifier detection accuracy and minimize the timing speed. To evaluate the performance of the proposed PSO-DT IDS several experiments on NSL-KDD benchmark network intrusion detection dataset are conducted. The results obtained demonstrate the effectiveness of reducing the number of features from 41 to 11, which leads to increase the detection performance to 99.17% and speed up the time to 11.65 sec.

Relyng on Internet and online procedures increased the potential of attacks launched over the Internet. Therefore, network security needs to be concerned to provide secure information channels. The concept of Intrusion Detection (ID) was proposed by Anderson in 1980. ID is based on the assumption that the behavior of intruders is different from a legal user. Intrusion Detection System (IDS) becomes an essential component of computer networks security. IDS aim to identify unusual access or attacks to secure internal networks, by looking for potential malicious activities in network traffic and raises an alarm whenever a suspicious activity is detected.

IDS can be categorized into two techniques: misuse detection and anomaly detection. Misuse detection uses well-defined patterns of attacks (attacks signatures) to identify known intrusion. While, Anomaly detection creates a normal behavior profile to identify intrusions traffic based on significant deviations from this normal profile. Anomaly detection techniques have the advantage of identifying the unknown attacks.

Several pattern classification techniques have been pro-posed in the literature for the development of IDS; including Fuzzy Logic (FL), Neural Networks (NN), Support Vector Machines (SVM), and Decision Tree (DT). One of the important problems for IDS is dealing with data containing high number of features. High dimensional data may leads to decrease the predictive accuracy of the IDS. Therefore, feature selection can serve as a pre-processing tool for high dimensional data before solving the classification problems. The purpose of the feature selection is to reduce the number of irrelevant and redundant features. Different feature selection methods are proposed to increase the performance of IDS including Genetic Algorithm (GA), Principal Component Analysis (PCA) and Information Gain (IG).

An anomaly intrusion detection system using Particle Swarm Optimization (PSO) to implement a feature selection followed by C4.5 decision tree classifier is being considered here. The effectiveness of the proposed PSO-DT IDS is evaluated by conducting several experiments on NSL-KDD network intrusion dataset. The results reveal that our proposed PSO feature selection based IDS increases the accuracy and speed up the detection time than other well known feature selection methods compared to.

An Overview

A. Feature Selection: Feature selection is one of the important techniques used for data preprocessing in IDS. It aims to improve the detection performance through the removal of irrelevant, noisy and redundant features. Feature selection can be achieved by two different methods: filter methods and wrapper methods. Filter methods rely on the general characteristics of the data to evaluate the relevance of the features, without depending on any machine learning algorithm to select the new set of features. While, wrapper methods exploit a machine learning algorithm and use the classification performance to evaluate the goodness of features. Genetic algorithm and PSO algorithm are included, with the aim of employing wrapper feature selection.

B. Genetic Algorithm (GA): Holland introduced Genetic Algorithm (GA), which has been successfully applied to solve a search and optimization problems. GA is a computational model to simulate the evolutionary processes in the nature.

The basic idea of a GA is to search a hypothesis space of individuals to find the best individuals. Each individual is called chromosome and is composed of numbers of genes. The GA procedure starts from generating an initial population of random chromosomes. Then the population is evolved for a number of generations, where the goodness of the chromosomes are gradually improve depending on the increasing value of the fitness function. Each generation of GA includes three fundamental operators: selection, crossover and mutation.

1) Selection operation: A population is created with a group of random chromosomes. Based on a fitness function the chromosomes in the population are evaluated and selected for the next generation.

2) Crossover operation: crossover randomly chooses a point in pairs of the selected chromosomes and exchanging the remaining segments of them to create the new chromosomes.

3) Mutation operation: randomly changes one or more components of selected chromosomes.

These three operations continue until a suitable solution has been found or a certain number of generations have passed. Since GA can find a global optimum solution it is well suited to the feature selection problems. Algorithm 1 shows the structure of a simple Genetic Algorithm (GA).

Algorithm 1 GA algorithm

Initialize a population of randomly individuals.

Evaluate population members based on the fitness func-tion.

while termination condition or maximum number of generation Not reach. do

Select parents from current population.

Apply crossover and mutation to the selected parents.

Evaluate offspring.

Set offspring equal to current population.

end while

Return the best individuals

C. Particle Swarm Optimization (PSO): Particle Swarm Optimization (PSO) is an evolutionary computation technique developed by Kennedy and Eberhart in 1995. PSO simulates the social behavior of organisms, such as bird flocking. PSO is initialized with a random population (swarm) of individuals (particles). Where, each particle of the swarm represents a candidate solution in the d-dimensional search space. To discover the best solution, each particle changes its searching direction according to:The best previous position (the position with the best fitness value) of its individual memory (pbest), represented by Pi = (pi1; pi2; :::; pid); and the global best position gained by the swarm (gbest) Gi = (gi1; gi2; :::; gid)

D. Decision Tree (DT):Decision tree (DT) introduced by Quinlan is a powerful data mining algorithm for decision-making and classification problems. DT classifiers can be build from large volume of dataset with many attributes, because the tree size is independent of the dataset size. A DT consists of three main components: nodes, leaves,and edges. Each node specifies a feature in the dataset by which the data is to be partitioned. Each node has a number of edges, which are labeled according to possible values of the feature in the parent node. An edge connects either two nodes or a node and a leaf.

The process of constructing a decision tree is basically a divide-and-conquer process. DT start from the root node and follow the edges down until a leaf node representing the class is reached, where it divides the dataset into subsets. This process terminates when all the data in the current subset belong to the same class. C4.5 algorithm uses Gain Ratio measure to choose the best attribute for each decision node during the building of the decision tree. Where at each H(D) finds the amount of entropy in class based subsets of the data set. That subset is split into s new subsets S = D1; D2; :::; Ds using some attribute, where a subset of data set does not need any further split if all examples in it belong to the same class. ID3 algorithm calculates the information gain of a split by and chooses that split which provides maximum information gain for the splitting purpose.

NETWORK INTRUSION DATASET

For the evaluation of researches in network intrusion detection systems MIT Lincoln Laboratory has collected and distributed the DARPA benchmark datasets. The KDD’99 dataset is a subset of the DARPA benchmark dataset prepared by Sal Stofo and Wenke Lee. KDD’99 train dataset is five million record of compressed binary TCP dump data from seven weeks of network traffic. Where, each KDD’99 training record contains 41 features (e.g., protocoltype, service, and flag) and is labeled as either normal orspecific attack type. The training set contains a total of 22training attack types, with an additional 17 attack types in the testing set only.

The attacks belong to four categories:

DoS (Denial of Service ) e.g Neptune, Smurf, Pod and Teardrop.

U2R (user-to-root: unauthorized access to root privi- leges) e.g Buffer-overflow, Load-module, Perl and Spy

R2L (remote-to-local: unauthorized access to local from a remote machine)e.g Guess-password, Ftp- write, Imap and Phf

Probe (probing:information gathering attacks) eg. Port-sweep, IP-sweep, Nmap and Satan.Leung and Leckie reported two problems in theKDD’99 dataset which affects the performance of resultsevaluation of intrusion detection systems.

10% portions of the full KDD’99 dataset contained only two typesof DoS attacks (Smurf and Neptune).These two types constitute over 71% of the testing dataset which completely affects the evaluation.

Since these attacks consume large volumes of traffic,they are easily detectable by other means and there is no need of using anomaly detection systems to find these attacks.

To solve these problems, NSL-KDD a new datasetis suggested. NSL-KDD dataset consists of selected recordsof the complete KDD’99 dataset.

C4.5 algorithm improves ID3 algorithm by using highest Gain Ratio that ensures a larger than average dividing step, C4.5 choose an attribute which provides the maximum information gain while reducing the bias in favor of tests with many outcomes by normalization.

PROPOSED ANOMOLY NETWORK INTRUSION DETECTION SYSTEM: (PSO-DT IDS) The proposed hybrid anomaly intrusion detection sys-tem is using the advantages of PSO feature selection in conjunction with C4.5 DT classifier to detect and classify the network intrusions into five outcomes: normal and four categories of intrusions. It consists of the following three fundamental building phases: (1) Preprocessing , (2) Feature selection based PSO and (3) Classification using C4.5 DT.

Concluding:The proposed PSO-DT intrusion detection system is evaluated using the NSL- KDD dataset, where 59586 records are randomly taken. All experiments have been performed using Intel Core i3 2.13 GHz processor with 2 GB of RAM. The experiments have been implemented using Java language environment with a ten-fold cross-validation.

Analyzing Facebook

Ronald J. Pawley

March 6, 2020

Many folks have conflicting thoughts as they evaluate Facebook that are both negative and positive influences. Some folks try to make a conscious effort to remove the negative as much as possible.

Facebook is great for social networking. Revealing too much about yourself on Facebook, however, can become quite detrimental to you.

It can also injure/destroy relationships with your friends and others in so many ways. I have seen this happen. Clearly, when you say offensive and insulting thing about others on a social network like Facebook, “you can’t unring the bell” the damage to that person is harmful and can last a lifetime.

I found the following research about Facebook very interesting and informative:

Top Economists Study What Happens When You Stop Using Facebook

February 29th, 2020

In the most recent issue of the prestigious American Economic Review, a group of well-known economists published a paper titled “The Welfare Effects of Social Media.” It presents the results of one of the largest randomized trials ever conducted to directly measure the personal impact of deactivating Facebook.

The experimental design is straightforward. Using Facebook ads, the researchers recruited 2,743 users who were willing to leave Facebook for one month in exchange for a cash reward. They then randomly divided these users into a Treatment group, that followed through with the deactivation, and a Control group, that was asked to keep using the platform.

The researchers deployed surveys, emails, text messages, and monitoring software to measure both the subjective well-being and behavior of both groups, both during and after the experiment.

Here are some highlights of what they found:

“Deactivating Facebook freed up 60 minutes per day for the average person in our Treatment group.” Much of this time was reinvested in offline activities, including, notably, socializing with friends and family.

“Deactivation caused small but significant improvements in well-being, and in particular in self-reported happiness, life satisfaction, depression, and anxiety.” The researchers report this effect to be around 25-40% of the effect typically attributed to participating in therapy.

“As the experiment ended, participants reported planning to use Facebook much less in the future.” Five percent of the Treatment group went even farther and declined to reactivate their account after the experiment ended.

“The Treatment group was less likely to say they follow news about politics or the President, and less able to correctly answer factual questions about recent news events.” This was not surprising given that this group spent 15% less time reading any type of online news during the experiment.

“Deactivation significantly reduced polarization of views on policy issues and a measure of exposure to polarizing news.” On the other hand, it didn’t significantly reduce negative feelings about the other political party.

This study validates many of the ideas from Digital Minimalism (indeed, the paper even cites the book in its introduction). People spend more time on social media than they realize, and stepping away frees up time for more rewarding offline activities, leading, in turn, to an increase in self-reported happiness and a decrease in self-reported anxiety.

The main negative impact experienced by the Treatment group was that they were less up to date on the news. Some might argue that this isn’t really negative, but even for those who prioritize current events knowledge, there are, obviously, many better ways to keep up with news than Facebook.

Perhaps most interesting was the disconnect between the subjects’ experience with deactivating Facebook and their prediction about how other people would react. “About 80 percent of the Treatment group agreed that deactivation was good for them,” reports the researchers. But this same group was likely to believe that others wouldn’t experience similar positive effects, as they would likely “miss out” more. The specter of FOMO, in other words, is hard to shake, even after you’ve learned through direct experience that in your own case this “fear” was largely hype.

This final result tells me that perhaps an early important step in freeing our culture from indentured servitude in social media’s attention mines is convincing people that abstention is an option in the first place.

Overview of Software Wallets, the Easy Way to Store Crypto

Similar to a bank account for fiat currency, a crypto wallet is a personal interface for a cryptocurrency network that provides reliable storage and enables transactions. Whether a cryptocurrency is securely stored or not, much depends on the wallet, which is only as secure as its private keys.

Wallets are generally either hot or cold. The funds in a hot wallet can be spent at any time, online. A cold wallet functions in contrast: not intended for regular cryptocurrency transactions, but funds can be received at any time. Wallets can also be divided into three groups: software, hardware and paper. Today, we will take a look at the most widespread group of crypto wallets ー software.

What is a software wallet?

Software wallets come in many forms, each with its own set of unique characteristics. Most are somehow connected to the internet and are hot in nature. Wallets are distinguished by a set of supported cryptocurrencies and software platforms such as Windows, Mac and other operating systems. Software wallets are available in three forms — desktop, mobile and online:

Desktop wallets are computer programs that store cryptocurrencies on a PC so that its information is not accessible to anyone but the user, whose private keys are kept only on the desktop.

Mobile wallets come in the form of a smartphone app and are easily accessible to their users at any time, considering most people don’t leave their homes without their phones. However, it is worth remembering that mobile devices are vulnerable to various malware and can be easily lost.

Online wallets are web wallets that can be accessed from anywhere and any device, making them more convenient, but the private keys are stored by website owners rather than locally on user devices.

So, the burning question on everyone’s mind is: Which of these software wallets do I choose?

Exodus

Exodus is one of the most popular software wallets for storing Bitcoin (BTC) and supports over 110 other cryptocurrencies. Launched in 2015 and based in Nebraska, the service is supported by all major software platforms.

The Exodus code is partially open-source. Private keys are controlled by the users and do not leave the device where the wallet is installed. The service’s philosophy implies the absence of any personal identification and interaction with banks. Exodus uses the instant digital asset exchange ShapeShift for its wallet’s exchange function, although fiat money exchanges are not supported.

Exodus is a free service, while its transaction fees are paid only to miners and determined automatically using the Bitcoin fee service. The size of a transaction in the wallet is determined by the number of inputs and outputs. The more input, the more expensive the transaction becomes. The wallet charges a portion of the commission for facilitating transactions made within the system.

Electrum Bitcoin Wallet

The Electrum Bitcoin Wallet is a reliable service that has been around since 2011. It is a so-called “thin” cold wallet, where the entire blockchain is not downloaded to the user’s device but is rather stored on the network servers. In this case, private keys are stored on the user’s computer in an encrypted form and are never sent to the server.

Versions of the Electrum Bitcoin Wallet can be automatically synchronized on different computers. If users want to use another client program or an online service in the future, they can easily export their keys there or import keys into a cold wallet.

This crypto wallet can sign transactions on a device disconnected from the network by saving a new transaction onto a USB flash drive and then loading it onto a device connected to the internet, where the new transaction can be imported onto the network. The wallet is functionally an analog of a hardware wallet, albeit with a slightly more complex chain of actions, and also uses two-level encryption.

Jaxx Liberty

Based in Canada, Jaxx was launched in 2016 by Anthony Di Iorio, CEO and founder of Decentral as well as a co-founder of Ethereum. Jaxx is available on most popular operating systems: Windows, Linux, Mac OS, Android, IOS and also as an extension in the Google Chrome web browser.

Over 80 cryptocurrencies are available as the ShapeShift exchange is also integrated into the Jaxx wallet for easy and fast transactions. The Jaxx platform does not support fiat money exchange operations or multi-signature. It is a free service, and its transaction fees are paid to miners and differ by currency. When transferring BTC, users choose from three options for fees, depending on the urgency of the transfer.

All of Jaxx’s code is open-source except for the user interface. Private keys are controlled by users and do not leave devices that have had wallets installed on them. To verify transactions, centralized validation technology is used. The intuitive controls render this wallet user-friendly and convenient to use.

However, the company has had its rough times. In 2017, Jaxx was hacked, and more than $400,000 in various cryptocurrencies was stolen. However, Jaxx Chief Technical Officer Nilang Vyas said in a Reddit post that, unlike hardware wallets, Jaxx is not designed for long-term storage of crypto assets and that users should store only small amounts of funds in their Jaxx wallets.

Atomic Wallet

Founded in 2017, Atomic Wallet is a desktop app that provides users with full control over their cryptocurrency savings, as the private keys and transactional data for this service are stored on users’ computers rather than on the provider’s servers.

Atomic Wallet is compatible with all known operating systems and currently supports more than 300 cryptocurrencies, including the most common ones, alongside most ERC-20 tokens and its own Atomic Wallet Coin (AWC). The app can be downloaded for free, but it does contain certain paid services:

Purchasing cryptocurrency with a credit card (a 2% commission and minimum commission of $10).

Currency transactions within the wallet, such as peer-to-peer.

Transactions conducted through ShapeShift.

As a solution that lacks servers, Atomic Wallet does not require registration from its users. Therefore, the wallet does not store any confidential personal information and does not utilize the services of intermediaries to conduct transactions.

All data transferred is encrypted, as users receive a unique “backup phrase” comprising 12 randomly generated words to recover access to their wallets to serve as a backup should other forms of verification fail, or in case a mobile phone is lost.

Bitcoin Core

Bitcoin Core was created in 2009 and is based on the wallet program code that was published along with Bitcoin’s project software, thereby ensuring streamlined functionality along the network.

In 2012, the Bitcoin Foundation began developing applications based on the original Bitcoin project code. The main focus was on the wallet as a dominant app that met the primary needs of the network: storage and money transfer.

Bitcoin Core was one of the first wallets to support SegWit technology and serves as a reference cold wallet for BTC. No other currencies are supported. The wallet can be downloaded as a desktop application on Windows, Linux and Mac.

The main advantage of Bitcoin Core is its security. All information is stored on the user’s PC, independent of third parties and other entities’ servers. A file with private keys is generated and stored by the user — no one else can access it.

With Bitcoin Core, the user can be guaranteed complete anonymity, including anonymized payments. Bitcoin Core uses an address rotation system, making it practically impossible to track the sender and the recipient addresses — provided that different addresses are used for each transaction.

Among the wallet’s shortcomings is low mobility, which may be unappealing for many potential users. Bitcoin Core lacks a mobile version, and this is likely to remain the case, as mobile use contradicts the wallet’s foundational principles of operation and security. Installing a wallet on another computer or even on a reinstalled OS will also not help to recover the funds, as the entire synchronization process (i.e., data downloading and verifying validity) would need to be repeated.

BitGo

BitGo is a blockchain company founded in 2013 and headquartered in Palo Alto, California. While originally a BTC wallet, BitGo has added support for other popular cryptocurrencies over the years. The BitGo wallet is a web wallet that can be connected through a desktop computer, laptop or other devices. The mobile version of the wallet allows storing keys on user devices. Additionally, keys can be transferred to other devices.

The company has developed two versions of its wallet for either individual or business use.

In addition to being an online wallet, BitGo offers a service providing reliable storage of digital assets for institutional investors through its partnership with Kingdom Trust. In the spring of 2018, the wallet began supporting the ERC-20 standard, expanding the list of supported digital currencies to 90. However, this is of little use to ordinary investors, as all ERC-20 tokens on BitGo are available only to institutional investors.

Each BitGo wallet has three keys: One is stored on BitGo, the second on the user’s device and the third through the Key Recovery Service software. To avoid third-party involvement, just two signatures are required to complete transactions. Access to the wallet is protected by two-factor authentication, and users must confirm their IP every time they log in to their wallets. BitGo charges a fee of 0.25% on all withdrawals up to 1 BTC alongside the usual mining fees.

Like Jaxx Liberty, the BitGo wallet has been at the center of a scandal. In 2015, BitGo and Bitfinex announced their collaboration to create a multi-signature wallet system. The companies decided to put user funds into a mixed storage, in which some were stored on large, offline wallets and the rest online. As a result, each user had three keys, two of which were stored by Bitfinex and the third by BitGo.

However, in August 2016, Bitfinex discovered that more than $60 million in BTC had been withdrawn from its users’ hot wallets. To this day, no explanation has been offered as to how the attackers managed to pull this off other than BitGo confirming on its official Twitter page that its servers had not been breached.

Crypto wallets going forward

Cryptocurrency wallets are an integral part of using Bitcoin and other cryptocurrencies. They are a fundamental element of the crypto infrastructure that allows funds to transfer across blockchain networks. Each wallet has its own advantages and disadvantages, so understanding how they work and what kind of activities they facilitate is essential before moving on to using them.

In any case, software wallets are becoming increasingly popular, and according to Atomic Wallet’s PR manager, Kristina Khachatryan, they are becoming more accessible and attractive every day:

“The software wallets are getting to be more and more accessible for a larger number of people, more multifunctional and filled with cool features at the same time losing nothing in the performance or the security issue. Moreover, the possibility of the decentralized staking is the central opening of this year. That’s why we see high potentials in this field of the software wallets and believe that the market will be surely driven to grow by the increased popularity of this product.”

Exodus’s communications manager, Davey Zelaya, is confident that the software market will develop at a faster pace as more cryptocurrency and blockchain solutions continue to be launched:

“We expect the market to continue to demand user-friendly software to interact with the increasing number of blockchain products and applications. In short, we want to make crypto easy for everyone. Right now, decentralized apps are still bulky and sometimes difficult to navigate. We want to change that.”

Design Fundamentals Portfolio

Design basics:

When it came to the design of my logo I decided to look a lot of classic Hip-Hop logos, one of my favourite designs was that of the infamous Death Row Records. Using basic line and shape techniques they created a logo which not only resonates with the name of the company but even the record label as a whole. This inspired me to create a logo using line techniques as the concept of only using lines is rather simple but the possibilities are exceptional.

This logo for a motorcycle store really stood out to me when I was looking for inspiration for my own logo as it embodies everything I personally feel a logo should have; it combines sleek typography and a few simple lines to create a stylish and minimalistic logo which accurately represents the brand. I hope to be able to carry this technique into my own logo however I would add some colour into mine to make it more attractive.

I explored several image formats for my app and I decided to use an SVG file for my map and logo as SVG images work using vectors rather than pixels, this is especially important for the map as people would need to zoom in order to see the map in detail so an SVG image format is necessary. For the other components of my app such as the interface itself I decided to use PNG and JPEG file formats as these will not be enlarged therefore it is not needed.

Colour is an important aspect of everything in life not just an app interface, if something has too little it won’t be very stimulating for the user and they may ignore it sometimes even unconsciously on the other hand if something is too colourful it may be overstimulating and the user may not be able to bear looking at it, therefore a perfect balance is needed. Throughout my research I discovered what is known as colour harmony; this refers to colours that are pleasing to the eye. There are several methods as to how to decide which colours are aesthetically pleasing alongside each other, such as analogous colours which refers to neighbouring colours on the colour wheel, there is also what is known as complementary colours which are the colours that lie opposite each other on the colour wheel among several others. The method for choosing a colour scheme I found most interesting was a colour scheme based on nature, this enticed me as I believe nature makes no mistakes therefore even if the colours in a particular nature setting do not follow a thematic colour scheme they still work well together and I found this to be a liberating and creative way to choose my colour scheme.

An app that does not follow a consistent set of design themes and structure will most likely be unappealing to the user as it will take them too much effort to work out the different designs, an app that is too difficult to navigate will lose its user fairly quickly. A good way of keeping to a consistent design is by using grid systems, by looking at websites such as the ones displayed above it is clear to see how designers separate the page into a series of boxes, this allows them to assign content into each of these boxes and keep a consistent level of design throughout, I intend to follow a similar procedure.

Visual hierarchy refers to the method of using all previously discussed design techniques such as typography, colour, size and space to guide a user through your design and allow them to navigate to the most essential information with ease. In the above examples we see how these illustrators use techniques such as size and colour value to emphasise the information that is most important or that should be read first.

Museum Research:

I looked at a number of the world’s most popular museums when conducting my research. I was very fond of the layout of “The Louvre” as it gave me an idea as to how I could structure my museum similarly. Since the whole point of my museum is to experience the progression of Hip-Hop from start to end I feel like a similar structure would be beneficial to my museum as I could locate the entrance at one end, have the exit at the other end and that way guests may experience the museum in chronological order.

The Natural History Museum gave me some inspiration as to how to structure the rooms inside the museum; I noticed that they not only divide the exhibitions based on each specific species but also by “zones”. These zones include a collection of rooms which are somewhat related to each other such as marine invertebrates and underwater mammals, this is a useful idea as it gives the guest a sense of familiarity whereas randomly scattering the rooms might confuse guests and ruin their experience. I decided I could implement this into my museum by basing the zones on sub-genres that have similarly sounding styles.

My museum will not only focus on the evolution of Hip-Hop as a whole but also on the individuals that helped shape it, this picture I took in the Stax Museum of American Soul Music gave me the idea to include items that belonged to some of Hip-Hop’s greatest pioneers such as Grandmaster Flash’s first turntable or Eminem’s lyric book.

This picture is from the Country Music Hall of Fame, this Wall of Records of the greatest country albums of all time felt like a brilliant idea and one which I could include in my museum. I decided to include this at the entrance to my museum as I believe it’s a great introduction to all of the amazing music available throughout the museum. I also believe it’s a great free attraction for guests who may not decide to purchase a ticket as they can still see every record that shaped Hip-Hop.

Interface/App design research:

The Student Beans app is a good example of good app design; it has a stylish colour palette but not one that is too obtrusive, it starts you out on a “featured” page which shows you all of the top deals, so you can start scrolling straight away. It has the common search icon at the top right-hand side of the screen exactly where you would expect to find it which is perfect and on the left hand side is the menu where you can access settings and all the more specific features of the app. Along the bottom of the app there are 4 tabs which allow quick and easy access to online offers and in store offers so you can easily look through the ones that suit you, there is also a fourth tab which takes you to student id at the click of one button. Not all apps have the same level of design and they aren’t as user friendly for example Snapchat; Snapchat recently revamped its interface, this is something never goes down well with users as once they become accustomed to having things in certain areas it becomes difficult to learn a whole new interface. Another bit of bad design from my perspective is the fact that the app opens straight away on the camera, on newer phones this might not be such a problem but only models that have become slightly more sluggish the camera can be slow to open which is not a good way to introduce users to your app.

Classroom tasks:

For my map I took inspiration from the design of the Louvre as I felt it would work well with the idea for my museum as it allows people to experience the evolution of Hip-Hop from its conception to where it stands today. For my logo I went with a vinyl record, I chose this design because in the early days of Hip-Hop records were the main form of listening to music other than cassette tapes, therefore I feel this design resonates closely with the museum and app as a whole. For my icon I chose the lone record as I felt it was simple enough to be used as an icon but still distinguishable for what it is meant to be.

The images above are an early concept for my app. I decided the main navigational options would be located along tabs at the bottom of the screen, this allows the user quick and easy access to the most important features of the app. The most notable features in my app are the personal tour guide and the timeline feature. The tour guide works by entering the number associated to the room you are in, a pre-recorded tour will then begin which explains everything in the room to you. The timeline feature is a way to take the museum home with you in a sense, as the whole point of the museum is to experience Hip-Hop’s evolution. The timeline feature allows you to do just that as you scroll and read through the moments that shaped Hip-Hop. I also decided to include a QR scanner that can be used to listen to snippets of every artists hit songs, this is an integral part to the museum and the app as it allows people to broaden their range of music.
