I had difficulty in making my latest post.  It would fail at Submit.

I had success when I saved a draft post.  I was able to edit the draft to submit.

Hi, 
How can I load a .m file with the big green arrow ?

Today we celebrated International Women's Day at Maplesoft. As part of our celebration, we had a panel of 5 successful women from within the community share their experiences and insights with us. 

Hearing these women speak has given me the courage to share my personal experience and advice to women in technology. If what I write here helps even one woman, then I will have accomplished something great today. 

-----

What do you do at Maplesoft?

My name is Karishma. I'm the Director, Product Management - Academic. 

Where did you grow up and where did you go to school (Diploma/degree)?

I was born and raised in Montreal to parents of Indian descent. Like most Indian parents, they “encouraged" me to pursue a career in either Law, Medicine, or Engineering, despite my true calling to pursue a career in theatre (at least that's what I believed it to be at the time). 

Given that I had no siblings to break the ice, and that rebelling wasn't my Modus Operandi (that came much later), I did what any obedient teenager would do: I pursued a career in Electrical Engineering at McGill University. In my mind, this was the fastest way to landing a job and fleeing the proverbial nest. 

Electrical Engineering was far from glamorous, and after two years, I was ready to switch. It was due to the sheer insistence of my mother that I completed the degree. 

So how did I end up pursuing a graduate degree in Biomedical Engineering at McGill University? It wasn't the future I envisioned, but the economic downturn in 2001-2002 saw a massive decrease in hiring, and the job that I had held-out patiently for during those four years became a far-off dream. So I did the thing I never imagined I would: I accepted the offer to pursue a Master's and the very generous stipend that came with it. In case you are wondering, I only applied because my father nagged me into submission. (Insistence and nagging are two innate traits of Indian parents). 

Contrary to what I expected, I loved my Master's degree! It gave me the freedom to immerse myself wholly in a topic I found exciting and allowed me to call the shots on my schedule, which led to my involvement in student government as VP Internal. But apart from the research and the independence, pursuing a master's degree opened doors to opportunities that I couldn't have imagined, such as an internship with the International Organization for Migration in Kenya, a job offer in Europe, and the chance to work at Maplesoft. (I guess my parents did know what was best for me.) 

What is the best part of your job?

It's figuring out how to solve problems our users have as well as the ones they might not realize they have. 

At Maplesoft, I work with some most brilliant minds I've ever encountered to build a product that makes math more accessible to our users, whether they be a student, researcher, scientist, or engineer. 

Some of the aspects of my role that I love the most include: 

• speaking to and learning from our customers, 
• interpreting the meaning behind their words, facial expressions, vocal intonations, and body language, and
• collaborating with the sales, marketing, and development teams to turn what was 'said' into tangible actions that will enhance the product and user experience. 

Most nights, when I leave work, I do so with a sense of excitement because I know my actions and the actions of those I work with will help our users achieve their goals and ambitions. There's no better high. 

What advice do you have for young women interested in a career in your field? 
Throughout my career, I've had the privilege to work with some amazing women and men who've given me advice that I wish I had known when I was an undergraduate student. If you are a woman pursuing a STEM degree or starting your first job in a tech firm, here are three tips that may help you: 

1.   Don't be scared of the 'N' word. 
Don't be scared of NETWORKING. I know it can be intimidating, but it truly is the best way to land a job, advance your career, or meet the person you admire most. Remember that networking can take place anywhere - it's not exclusive to networking events. Some advice that I received that helped me overcome my fear of networking: 

• Smile - Before you approach a person or enter a networking session, force yourself to smile. It will help you diffuse any tension you are holding and will make you appear more approachable. 
• Research - Take the time to research the person(s) you would like to meet. Find out as much as you can about them and their company. Prepare some icebreaker questions and other questions to help carry the conversation forward ahead of time. Remember that people like to talk about themselves and their experiences. 
• Don't take it personally - The person you approach may find networking equally tricky. So if they seem disinterested or aloof, don't take it personally. 
• Just do it - Networking gets easier with practice. Don't let a failed attempt set you back. The worse thing that will happen is that you don't make a connection. 

 2.   It's ok to ask for help.
If you are a woman in an environment that is dominated by men, you might hesitate to ask for help. DON'T! There's nothing wrong with asking for help. That said, many women ask for help in a way that undermines their confidence and thus erodes others’ perception of them. Next time you need help, have a question or require clarification, take a moment to phrase your request, so you don't inadvertently put yourself down. 

3.   Play to your strengths
Don't think you need to know everything. Nobody expects it. If you landed a new job or co-op placement, and you are finding yourself doing things you've never done and don't come naturally to you yet, don't let your brain convince you that you don't deserve it. Remember that you earned it because of your qualities and strengths. 

I want to set up an RSS or IFTTT so that I get a notification on my phone whenever there's something new in the Active Conversations stack. My phone uses Google Android. I'd prefer to not need to rely on email/gmail for the notification; something more endogenous to Android would be preferable. I've never used RSS or IFTTT, so detailed instructions are preferable.

I found that i can use  simplify under assumption to gain the result :

simplify((-p^3)^(1/3), assume = negative);
                               -p

simplify((p^3)^(1/3), assume = positive);
                               p

But confusing ! I expected the simplify command just with the option=symbolic works at the same manner ?

Recently I posted a question "how to insert a loop".
Without my knowledge, the post is deleted.
Mention the reason for deleting the post.
 

We need a check-off box for Maple Companion in the Products category of Question and Post headers.

While you're looking at that, there's also a bug that the Product indication gets stripped off when converting a Post to a Question, which is a common Moderator action.

Is anyone accessing the https://www.mapleprimes.com/questions redirected to this page https://www.mapleprimes.com/errors/500.aspx?aspxerrorpath=/questions/default.aspx ?

Hi, 

does anyone remember of a recent question (maybe a post) about a bouncing ball over a hilly ground?
I can't put the finger on it.

TIA

One decade on MaplePrimes

Always I Wish A Wonderful Year In Mathematics As Annus mirabilis

We are currently in the process of updating the support FAQs at https://faq.maplesoft.com. We’ve been working on updating the existing content for clarity, and have added several new articles already.

The majority of our FAQs are from questions people ask us in Technical Support at support@maplesoft.com, but we’d also like to like to add content from other sources.

Since we have such a great community here at MaplePrimes, we wanted to reach out and ask if there are any articles or questions that you'd like to see added to our FAQ.

We look forward to hearing your feedback!

When writing a post on MaplePrimes it is possible to access the source code, which allows to introduce/edit many attributes. Is it possible to observe the source of another post?

Generally when I respond to questions on this site, I make sure that I tick the checkbox requesting that I get an email when updates are made to the thread.

I've just realised that I have been receiving no such updates for a week or so. Two possibilities

1. Problem with Mapleprimes website, meaning that email updates aren't being generated/sent
2. Problem with my ISP

Before I try investigating (2) above, I'd just like to know if anyone else has seen any issue which might be explained by (1) above
